• Strong Python skills — FastAPI or similar production web framework experience required
• Strong frontend skills (React, Next.js, TypeScript) for the chat, memory, and activity surfaces
• Experience with auth, billing, and multi-tenancy in production products
• Container orchestration experience (Kubernetes, Nomad, ECS, or equivalent)
• Experience with AI-native tools (Cursor, Claude Code, model APIs)
• Knowledge of agents, LLM gateways, rate limiting, and abuse prevention
• Comfortable working across frontend, backend, infrastructure, and AI workflows

The kind of person we want: someone who has shipped a consumer or prosumer product they're still proud of, and who responds to an aggressive timeline with "tight but doable if we cut X, Y, Z" rather than "let me spec it first."

Bonus skills:

• Experience with agent frameworks (Hermes, OpenClaw, LangGraph)
• LLM gateway or proxy work
• Stripe subscription billing at scale

1. Introduction

We are building a multi-tenant hosted platform that gives anyone their own personal Hermes agent running in the cloud in under 60 seconds. No terminal, no API keys, no configuration. The agent persists, remembers them, and gets better over time.

This project includes:

• Per-user Hermes containers with network and storage isolation
• A warm pool provisioning system for instant signup-to-first-message
• A production-hardened chat, memory, and activity interface
• An LLM gateway that meters usage, enforces caps, and prevents abuse
• Bundled Claude Sonnet access — users never see an API key or model selector
• Stripe billing infrastructure and self-serve subscription flows

2. Requirements

Platform and provisioning

• Per-tenant container orchestration via Kubernetes or Nomad
• Warm pool pattern for sub-90-second provisioning
• Idle sleep and fast wake (under 2 seconds on incoming message)
• Persistent per-tenant memory and conversation storage
• Auth via Clerk or Auth0 (email + Google OAuth, email verification required)

Frontend

• React, Next.js, TypeScript, Tailwind, shadcn

• Graceful handling of connection loss, agent timeouts, container restarts
• Streaming responses, conversation history, new-thread flows

LLM gateway

• Proxy every Anthropic API call from every tenant container
• Hold Anthropic API keys server-side; tenant containers never see them
• Per-tenant metering with second-by-second granularity
• Hard daily and monthly cost caps
• Circuit breakers for runaway loops
• Ops kill switch for any tenant

Billing and ops

• Stripe subscription integration at $20/mo
• Self-serve upgrade, downgrade, cancel
• Internal ops dashboard for user management and anomaly response
• Runbooks for common failure modes

3. Non-Goals

• Developer-facing platform
• Self-hosted desktop or mobile apps
• Skills marketplace or plugin ecosystem
• Workflow builder, triggers, scheduled agents
• Team accounts, SSO, enterprise features
• Multiple LLM providers or model selection
• Bring-your-own API key
• Forking Hermes — we track upstream and contribute back

4. Prior Art

• Hermes Agent — the open-source framework we build the hosted experience on top of
• OpenClaw — the largest agent framework today and reference for community patterns and growth dynamics
• LangGraph Deep Agents — architecture patterns for stateful long-running agent workflows
• Anthropic MCP — server design patterns for tool interfaces and permission-aware context
• Cowork (Anthropic) — polish bar and UX patterns for non-technical AI agent products
• Cursor agent UI — interaction model for AI agents in consumer products

Location: Remote — Anywhere (Open to applicants located anywhere around the globe)

Fueled is a leading digital strategy, design, and engineering agency. We are a 300+ person team that has designed and built hundreds of digital products and experiences for brands like Google, Apple, The New York Times, ESPN, Victoria’s Secret, MGM Resorts, Albertsons, and CLEAR.

As a Senior React Native Engineer at Fueled, you will champion the power of React Native to architect, build, and scale high-performance, cross-platform mobile applications that deliver premium user experiences.

Drawing on your prior experience with React for the web, you’ll design end-to-end solutions utilizing React Native, Expo, TypeScript, and Node.js-based back-end integrations. You will rely on strong typing to create robust data models, state management, and application architecture for complex, business-oriented apps.

Additionally, you’ll integrate with REST/GraphQL APIs, implement effective caching strategies, and establish automated mobile CI/CD pipelines to ensure seamless testing, building, and deployment of reliable, real-time functionality at scale.

Your work will turn ambitious ideas into maintainable, future-ready mobile systems that evolve with client needs, raise the bar for quality and performance, and consistently drive measurable outcomes.

Intentionally remote and globally distributed across six continents, our team thrives in a culture that values flexibility, creativity, and cutting-edge technology. Together, we’re shaping the future of digital experiences.

What you will do:

• Architect and build polished, cross-platform mobile experiences that turn user engagement into lasting loyalty. You’ll apply modern React Native (Expo) patterns and tooling to deliver performant applications that feel truly native on iOS and Android.
• Own the end-to-end delivery of key product features, from concept to app store deployment and beyond. You won't just code tickets; you'll shape the technical approach, make critical architectural decisions, and ensure what we ship is robust, scalable, and maintainable.
• Elevate the team’s velocity and craft by introducing, validating, and championing tools and practices that raise the technical bar. You’ll proactively identify bottlenecks – whether in state management, native bridges, or CI/CD pipelines – and implement solutions that make the entire team more effective.
• Bridge the gap between ambitious creative vision and technical reality in a mobile context. You’ll collaborate closely with designers and strategists to challenge assumptions, explore what’s possible on mobile, and deliver solutions that balance exceptional user experience with a first-class developer experience.

What you will achieve:

• From Day 1, you’re shipping a tangible feature for a live client project, building immediate momentum.
• Within the first month, you’ll own and deliver a key mobile feature end-to-end and improve a core performance metric (like app startup time or frame rate) by at least 10%.
• You will enhance team efficiency by creating reusable components, scripts, or processes that are adopted by your peers.
• By end of the project, you’ll have spearheaded a significant project phase from concept to app store launch, on time and to a high standard.
• Your expertise becomes a multiplier, evidenced by positive client or team feedback on your ability to solve complex mobile challenges.

About you:

• You think in cross-platform systems and reusable components. You get genuine satisfaction from designing a React Native architecture that is intuitive, performant, and delivers a consistent, high-quality experience on both iOS and Android.
• You’re a proactive problem-solver who doesn’t wait for perfect requirements. You thrive on digging into ambiguity, asking "why," and prototyping solutions to complex challenges involving native modules, third-party SDKs, and smooth data flow.
• You have a strong point of view, held loosely. You can articulate a compelling case for a specific technology or architectural approach (like state management libraries or navigation patterns) but are equally committed to the team's final decision and its success.
• You see the "full stack" as a single, interconnected challenge. You're comfortable crafting a polished, dynamic mobile UI with React Native and then diving into the back-end logic, API design, or platform-specific native code that makes it all possible.
• You are a natural collaborator and translator, able to explain mobile-specific constraints to designers and strategic goals to other engineers, ensuring the entire multidisciplinary team is building momentum together.

You will bridge the gap between business requirements and technical implementation, taking an active role on both sides and defining how the application looks as well as how it works.

Your responsibilities include:

• Ensuring that precise financial instruments are easy to use and to understand.
• Optimizing every millisecond of user interactions.

• Strong attention to detail, ensuring clean, organized, and maintainable code.
• The ability to effectively collaborate with coworkers across multiple time zones.
• Familiarity with cryptocurrency and blockchain technologies.
• A Bachelor’s degree in Computer Science, or a closely related field.

About the Role:

We're looking for a backend engineer who can own and evolve our Ticketing & Ride Request (TRR) system — the service that handles everything from a rider tapping "Request a Ride" to a vehicle arriving at their station. This is a high-throughput, event-driven system where reliability isn't optional; real people are standing on a platform waiting for their ride.

You'll also contribute to the broader backend infrastructure that supports our suite of applications — think message queues, caching layers, database performance, and service-to-service communication. If you've ever been the person on your team who gets pulled into debugging the weird one, you'll feel at home here.
We care far more about how you think than where you went to school or how many years are on your resume. To show us you actually read this posting and aren't auto-applying, start the first sentence of your cover letter with the words "Ride request received." — we'll know you're paying attention.

• Designing and maintaining the TRR backend — ride matching, station queueing, request lifecycle management, and fare calculation
• Building and operating services on top of PostgreSQL, Redis, and RabbitMQ in a Kubernetes environment
• Improving system observability — tracing, metrics, alerting — so we catch problems before riders do
• Collaborating on API design with our frontend, mobile, and operations teams
• Participating in incident response and post-mortems; we run blameless retros and expect engineers to dig into root causes, not just restart pods
• Contributing to capacity planning and load testing as we scale to new deployment sites

• Deep fluency in at least one backend language (TypeScript/Node.js, Go, Python, or Java) — we use TypeScript heavily but value polyglot thinkers
• Hands-on experience with PostgreSQL (query optimization, indexing strategies, schema migrations) and Redis (caching patterns, pub/sub, rate limiting)
• Familiarity with message broker patterns — RabbitMQ preferred, but Kafka or NATS experience translates well
• Solid understanding of distributed systems fundamentals: consistency models, failure modes, backpressure, idempotency
• Experience with Kubernetes in production — not just deploying, but debugging networking issues, resource contention, and pod lifecycle surprises
• Strong debugging instincts: you're the kind of engineer who reaches for tcpdump or strace before restarting the service

• Experience with event-driven architectures or CQRS patterns
• Familiarity with Temporal.io or similar workflow orchestration frameworks
• Background in transit, logistics, or any domain where latency directly impacts a physical-world experience
• Experience operating multi-tenant or multi-site deployments
• You've written a runbook that actually saved someone at 2am

Job Description:

B12's engineering team views software as a craft, but improving the world as the reason to practice it. Our engineers are responsible for prioritizing, conceptualizing, co-designing, building, testing, and engaging users for any concept we are building out. We’re generalists in encouraging each other to experience the full stack, but we’re also aware of each other’s preferences in the stack. For this role in particular, we’re searching for a full-stack engineer who brings strong backend skills (and an interest in using them) to the product. We mentor and teach where we can, both inside and outside of the company.

We value sharing our work with the outside world. Our team has published papers on forming expert flash teams and machine-mediated worker hierarchies. We’ve baked our research into Orchestra, the system that coordinates our expert and machine teams, and released Orchestra into open source to contribute our software back to the community.

We hope our engineers have more longevity than any one tool we use, but here is a sampling of our current thoughts about technology:

• We live on Python/Django and TypeScript/React.
• We store blobs in Amazon’s S3, munch on them in Amazon’s EC2, develop in Docker, and deploy containers to Amazon’s Elastic Beanstalk.
• We believe PostgreSQL should be the first system you consider when thinking about persisting structured data.
• We clean and centralize data in Amazon’s Redshift, and are able to answer almost any question in SQL.
• We leverage AI in our product and our internal tooling, and faced with a landscape in constant flux, try to pick the right model or agent on a task-by-task basis.
• We have near-full test coverage on the backend, and are making progress on our frontend and integration tests.
• We set up continuous integration and deployment because, while this model comes with its own pains, we’ve disliked being on fixed release schedules on previous projects.
• We like to move fast and support point-in-time recovery :).

You’d be a good fit if

• You have at least 4 years of experience building products and systems in production.
• You are an amazing communicator.
• You feel comfortable managing your time and deciding among competing priorities.
• You are passionate about the future of work.
• You enjoy learning and teaching.
• You have some mobile experience.
• You are comfortable working with backend and frontend technologies, but have a deeper background and interest on the backend side.
• You care about and want to contribute to our mission of helping people do meaningful work.

Don’t fear:

• We're somewhat flexible on the number of years of previous experience for this role. We highly favor talent and interest.
• Some candidates may see this list and feel discouraged because they don’t match all the items. Please apply anyway: there’s a good chance you’re more wonderful than you think you are.
• B12 is a safe place for human beings. We particularly encourage you to apply if you identify as a woman, are a person of color or other underrepresented minority, or are a member of the LGBTQIA community.

How to apply

Please provide:

• A pointer to your CV, resume, LinkedIn profile, or any other summary of your career so far.
• If you have a profile on websites like GitHub or other repositories of open source software, you can provide that as well. If you don’t have one, it’s still very possible for us to get along just fine!
• In addition to the traditional application details, we also ask that you complete a small technical challenge below. Two notes:
  • By virtue of submitting your application via a public platform like GitHub, it's possible for people to search for projects with "B12" in the repository name/description/contents and see that you have applied. You can obfuscate these details for your privacy, but contact us if you could benefit from a slightly different process to further protect your privacy.
  • We’ve never tried a “write code to apply to B12” exercise before, and introduced it because of a recent deluge of AI-generated/AI-mediated applications that has made reviewing inbound applications infeasible for us. We hope that introducing this exercise results in a smaller number of qualified candidates without serving as too much of an impediment. You are welcome to use AI assistance on this exercise (we did!). We imagine we’ll iterate on this experiment, and very much welcome your feedback on your experience.

To submit an application, create the following Python script that is executed via a GitHub Action (or continuous integration on any other Git forge). The script should:

• POST to https://b12.io/apply/submission with the following JSON-encoded payload in the body. All fields are required:
  

  {

    "timestamp": "2026-01-06T16:59:37.571Z",

    "name": "Your name",

    "email": "you@example.com",

    "resume_link": "https://pdf-or-html-or-linkedin.example.com",

    "repository_link": "https://link-to-github-or-other-forge.example.com/your/repository",

    "action_run_link": "https://link-to-github-or-another-forge.example.com/your/repository/actions/runs/run_id"

  }

  • Make the timestamp an ISO 8601 timestamp
  • The action_run_link is a page similar to https://github.com/marcua/ayb/actions/runs/20561457327 (might differ if you’re using a forge other than GitHub), which allows us to see the continuous integration run that POSTed to B12
  • We’ve pretty-printed for readability here, but the post body should contain no extra whitespace (compact separators), have keys sorted alphabetically, and be UTF-8-encoded. For example, the canonicalized payload above is
    {"action_run_link":"https://link-to-github-or-another-forge.example.com/your/repository/actions/runs/run_id","email":"you@example.com","name":"Your name","repository_link":"https://link-to-github-or-other-forge.example.com/your/repository","resume_link":"https://pdf-or-html-or-linkedin.example.com","timestamp":"2026-01-06T16:59:37.571Z"}

• Include a header called X-Signature-256 in the post request
  • The value of the header should be sha256={hex-digest}, where the hex digest is the HMAC-SHA256 of the raw UTF-8-encoded JSON request body, using the signing secret as the key.
  • Use a signing secret of hello-there-from-b12 (yes, it’s public, but treat it like a secret in your implementation ;))
  • As an example, the payload above will have a hex digest of c5db257a56e3c258ec1162459c9a295280871269f4cf70146d2c9f1b52671d45
• If the POST is successful, you will receive an HTTP 200 with a response of
  '{"success": true, "receipt": "your-submission-receipt"}'
  • Print that receipt in your continuous integration task
  • To confirm your submission, copy/paste the receipt into the field below

Why Work With Us.

• Opportunity. We are at at the forefront of developing a web-scale crawler and knowledge graph that allows ordinary people to participate in the process, and share in the benefits of AI development.
• Culture. We’re a lean team working together to achieve a very ambitious goal of improving access to public web data and distributing the value of AI to the people. We prioritize low ego and high output.
• Compensation. You’ll receive a competitive salary and equity package.

We are looking for a high-functioning psychopath to help bring the next wave of hybrid web2/3 applications.

You will be joining a team of top-tier self-selected sado-masochists, who work here because they can’t really work anywhere else. We value rapid communication and direct feedback, both internal and external. Breakneck pace shipping, autonomy and ownership, and constant experimentation are table stakes. Apologies in advance.

What Sparks Your Enthusiasm

• Shipping nonsense to billions of users
• That point of a futile debugging session where you start to question your sanity and everything becomes hilarious
• Finding interesting/troubling ways to solve engineering problems
• “Huh, that’s weird”, gives you a sense of giddy panic
• A constant feeling like your spinal column has been struck by lightning

What Turns You Away

• “It works on my machine”
• “The user should be able to figure it out”
• “That isn’t my problem”
• Feeling generally calm and in control of the situation

Requirements:

• Typescript
• React
• Self-destructive tendencies
• CSS Frameworks (Tailwind, MUI, etc.)
• Medically significant but non-terminal caffeine addiction
• Experience with Git/Github in a distributed team
• Experience integrating with REST/GraphQL/GRPC APIs
• Security Minded
• Comfort in a young, chaotic, rapidly evolving small team startup environment
• Ability to pick up and learn new stacks and tools on zero notice

Nice to haves:

• Cosm.js or Web3.js experience, general experience developing with crypto focused javascript libraries.
• Experience with NPM release best practices
• Experience working with and configuring bundlers (Webpack, Vite, etc.)
• Experience with browser and mobile data storage, ie LocalStorage, SQLite
• Performance conscious development, as the majority of the global user base is on mobile phones
• Integration and unit testing experience

Day-to-Day Responsibilities:

Actual: 

• Desperate banging on keyboard
• Ripping hair out over encoding errors
• Not learning from previous mistakes about encoding errors
• Ripping hair out over encoding errors

Formal:

• Design Implementation: Work closely with the design team to bring concepts to life, using provided designs as a foundation while exercising autonomy in execution.
• Feature Development: Take ownership of features from planning to release, including scoping, task management, and prioritization.
• Documentation Analysis: Research and review available documentation to guide development, navigating and interpreting scarce or ambiguous resources.
• Testing and Debugging: Conduct thorough testing and extensive debugging to ensure high-quality deliverables, iterating through multiple cycles as needed.
• Collaboration: Engage with the protocol team to facilitate smooth integration of features, providing technical guidance and feedback.
• Continuous Improvement: Participate in the release process, ensuring stability and performance, and contribute to ongoing improvements and refinements.

Cultural:

• Take on new features or bug fixes, with full ownership
• Scoff at the lack of documentation in our field
• “Reverse engineer” protocol level … stuff… to integrate into client
• Debug, debug, debug
• Release and iterate
