🚀 Hermes Web: Call for Founding Engineer

Hermes Web is looking for a founding engineer to build the first polished, hosted personal AI agent product.

Some facts about us:

• Incubated by Open Core Ventures, the studio founded by Sid Sijbrandij (ex-CEO of GitLab)
• Building the hosted, non-technical-user version of Hermes Agent — the fastest-growing open-source agent framework after OpenClaw
• OCV underwrites infrastructure and LLM costs, so you optimize for growth and polish, not unit economics
• Fully remote, product-focused, compressed sprint cadence

If you want to own product and engineering end-to-end, ship consumer-grade polish in a space that's still raw, and help define what a mainstream AI agent product looks like, this is for you.

Project described below.

Requirements

• High agency, ship fast without hand-holding
• 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
• Production experience hardening agentically-generated code
• OSS contributions
• Consumer AI product experience (Cowork, Cursor, or similar)

Project: Hosted Hermes Agent Platform

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
• Multi-tenant chat, memory, and activity surfaces
• 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

Founding CTO at Redbolt.ai 

Redbolt AI is the security and reliability layer for in-production AI systems. It’s the commercial open core evolution of NVIDIA's open source red-teaming framework, garak, and NeMo Guardrails. Redbolt builds on trusted open source technology and adds the security layer that empowers users to deploy AI at scale.

We're looking for a Founding CTO to build Redbolt into an era-defining AI technology. As the founding CTO, you’ll define initial product vision, build commercial features and an engineering team to accelerate product velocity, get closer to customers, and deepen open-source contributions to NVIDIA's Garak. 

The opportunity

The market for AI security is early but moving fast. The risks of unguarded AI systems are well-known but the infrastructure to protect against these risks don’t really exist yet.

Redbolt starts with a meaningful foundation: NVIDIA's open-source tools already have community traction and credibility. Your job is to turn that into a product and company that enterprises depend on.

If you've been looking for the right moment to build something that matters, this is it.

The role

As the technical founder, you will: 

• Defining the vision. What should this company become? What's the product roadmap that turns open-source adoption into a billion-dollar enterprise business? You'll own that strategy.
• Building the foundation. You're writing code, shipping product, and making architectural decisions that will compound for years.
• Hiring the team. You'll recruit and lead the engineers who build Redbolt alongside you.
• Partner with a CEO. Once there's traction, OCV will lead a search for a co-founder CEO to partner with you - someone to own go-to-market, fundraising, and business operations while you own product and engineering. You'll be deeply involved in selecting that person.

About you 

You're a deep technical expert in LLM security, ML engineering, or adjacent infrastructure. You understand how these systems fail and how to prevent them.

You've operated at a high level technically: staff/principal engineer, engineering lead, or founded something yourself.

You're entrepreneurial. You've been waiting for the right opportunity to build something from the ground up, with real support and resources behind you.

You have conviction about the AI security space. You've thought about what needs to exist and have opinions about how to build it.

The Investor Role at OCV

As an Investor at OCV, you’ll identify and research promising open source projects and build investment cases. 

Unlike traditional venture investing, your job doesn’t stop there. You’ll launch these companies as interim CEO – working directly with technical founders to drive early growth. Think part investor, part co-founder.

What you will do

• Research and evaluate OSS projects for commercial potential
• Identify CTO candidates from these projects 
• Launch companies as interim CEO, driving early product strategy and GTM
• Help identify and recruit CEO candidates once the company has momentum

About You

We're looking for 0-1 product managers, product-obsessed founders, or product centric investors who are obsessed with identifying the next great technologies and building generational products and companies. You know how to talk to users, do things that don’t scale, build something people want, and move fast.

You could be a great investor at OCV if:

• You move fast: Growth defines startups—you live for velocity and rapid iteration
• You have a founder mentality: You do whatever it takes, take big swings with imperfect information, and learn quickly from failures
• You understand technology: Technical background helps, but fluency in software concepts is required. Experience at a top-tier software company is ideal
• You're relentlessly curious: You dig deep to understand how things work at their core
• You sweat the details: Nothing falls through the cracks on your watch
• You bias toward action: You balance big ideas with concrete execution. You'll do the grunt work. Movement creates momentum

Compensation

Cash

Commensurate with market and experience 

Equity

Investors can receive direct equity issuance in companies they help incubate (grants and terms are set company-specific equity grant agreements). As an example and for illustrative purposes, OCV offers the most favorable risk-adjusted path to wealth creation in venture:

• Direct equity ownership: Receive 1% equity in multiple companies you incubate, vesting over just 9 months instead of the typical 4-year schedule.
• Compared to carry in a traditional fund: You receive cash at exit without the entire fund needing to clear its performance hurdle (typically 8% annual returns to LPs before GPs earn carry). To illustrate: 50bps of carry on a $100M fund requires an 4x return on invested capital to earn $300K. A single $200M exit on a 1% stake at 50% dilution can yield $1M.
• Compared to founder equity: You launch and support 3 active companies at a time, building a 12-company portfolio over 3 years. That's 12%+ aggregate equity across 12+ companies—founder-level ownership with more shots on goal.

The Open Core Ventures (OCV) Catalyst Program is a 3 month OSS project incubator aiming to support open source maintainers in the growth of their open source projects. Projects such as developer tools, artificial intelligence infrastructure/implementation, and data transformation (or any that solves a real problem and has potential for commercial viability) will be considered for Catalyst and will receive support and mentorship from OCV team. There is potential for top-performing projects to become OCV companies at the end of the program — 4/11 Catalyst projects became OCV companies, or their authors became OCV CTOs, in 2025. 

Participants in Catalyst will collaborate with OCV and their batch to establish and work towards clear, measurable objectives, focusing on metrics such as contributor growth, community expansion, and increased adoption. OCV provides $10,000 to support the growth of Catalyst projects, and it is not expected that authors work on their project full-time during Catalyst (most particpants hold full-time positions while in Catalyst). OCV is committed to advancing the growth of open source through providing the sponsorship resources and aims to amplify the impact of open-source projects and position them for long term success. Eight project authors will be accepted Applications will be reviewed on a rolling basis and are due by June 19, although may close sooner if all eight spots are filled.

Catalyst v2 kicks off on July 7, 2026.
