We are seeking an experienced Staff Platform Engineer / Software Engineer who will serve as a technical leader with dozens of engineering teams. You are someone who enjoys bridging the gap between software engineering and systems architecture, and not just managing infra, but building Internal Developer Platform (IDP) on Kubernetes, and APIs that enable scalability, efficiency, productivity, and developer joy. You are a "doer" who can pivot from writing high-quality production code to influencing the architectural direction of our CI/CD pipelines and service catalogs (e.g., Backstage), as well as be the next frontier of Generative AI integration.

Our Developer Experience (DevEx) organization’s mission is to partner with SentinelOne engineering teams to accelerate the velocity of software delivery through continuous innovation and standardization. We are building a platform that serves nearly 1,000 engineers to release services and features to our customers, making it easy to move from POC to production safely and quickly. We're also transforming our CI/CD from a traditional pipeline into an AI-driven engine - you will help us build a platform where AI proactively helps developers write & ship code, generates high-coverage test suites on the fly, and performs the first pass of PR reviews with human-level context. 

What Will You Do?

• Partner with Engineers, Build & Automate: The engineering teams are our primary customers - you will be working with them to understand their pain points and find long term solutions.
  • You will be building the IDP as the "Golden Path", and tools that improve the quality of life and streamlining the development process for the teams, so that they can build without having to worry about the underlying infrastructure.
  • You will be also building scalable solutions in collaboration with other infrastructure teams.
• Modernize the Stack: Collaborate with architects to evaluate and implement modern tools (e.g., ArgoCD, GitHub Actions) and deployment strategies (Canary, Blue/Green).
• Lead the AI-Driven CI/CD Shift: Architect and implement AI-powered workflows that assist in code generation, automated testing, and intelligent PR analysis to eliminate developer friction.
• Operational Ownership: Identify causes of toil across engineering orgs and eliminate them through automation, enhancing overall system reliability and developer satisfaction.
• Cross-Functional Influence: Partner with Product, Security, and Finance teams to align technical roadmaps with business value and customer needs. You will influence strategy and ensure our platform is as lean as it is powerful.
• Impact: You will participate in the full software development lifecycle, including requirements analysis, architecture design, coding, testing, and deployment.
• Deal with global scale: Our security SW products protect 15,000 enterprise and government clients across the globe, incl. 4 of Fortune 10, and process 9+ Petabytes of data daily and 3+ Trillion security events across multiple AWS/GCP regions and GovCloud, supported by a large Kubernetes control plane with 80+clusters and tens of thousands of nodes.

Our stack: Go, Python; Kubernetes, Docker, AWS, GCP, FedRAMP; GitHub Actions, ArgoCD; GitHub Enterprise; depending on the requirements of the service for communication, we use Kafka, REST API, GraphQL, gRPC, etc.; Postgres, MongoDB, Redis, ClickHouse; Prometheus/Thanos, Grafana

What Skills and Knowledge Will You Bring?

• Demonstrated proficiency in Go or Python. Experience in the full SDLC, from requirements to production-ready code
• Experience with AWS and/or GCP. Knowledge of Kubernetes or similar orchestration systems
• Experience with CI/CD tooling at scale (e.g., GitHub Actions, ArgoCD, Jenkins etc.) and GitOps approach
• Strong experience with Terraform, Pulumi, or similar IaC frameworks
• Familiarity with DevEx fundamentals, including Service Catalogs (Backstage), REST APIs, or gRPC
• Familiarity with both SQL (Postgres) and NoSQL (MongoDB, ClickHouse, or Redis)
• You are passionate about (and ideally have experience in) integrating LLMs and AI agents into the developer workflow to drive productivity
• Excellent problem-solving skills, strong ownership and accountability, with proven experience driving large, impactful projects
• Strong communication skills and ability to articulate technical concepts and influence engineering direction across teams, departments, and stakeholders in multiple time zones

We’re building a new product from scratch - focused on pragmatic, production-ready LLM-based agents.
The research and architecture phase is happening. Now we need engineers who will help turn those decisions into a real, scalable system.
This is not about blindly playing with prompts.
This is about building backend services, APIs, evaluation pipelines, and infrastructure that make agentic systems reliable in production.
We’re tackling a real-world problem with a clear path to market, backed by SafeQ Cloud - and you’ll also help shape and improve the in-house tools that power the product.

You won’t just get tickets — you’ll be part of discussions, refinements, and decisions.

If you’d like to work remotely, no problem. We’re used to hybrid collaboration based on team agreement.

WHAT WE OFFER:

• Things to be fresh. We’re building new AI products just now - and you can be part of the journey from start to finish. You’ll work across a wide range of AI disciplines, from text processing through image analysis to process automation
• No coding monkeys. We build solutions, not just follow specs.
• Work from idea to delivery.
• A manager-less structure. No hierarchy, everyone has a say.
• A team that decides. Hiring, promotions, direction - all in the team.
• No bulls**t KPIs.
• Learning and knowledge sharing is part of the job.

WHAT WE EXPECT FROM YOU:

• TypeScript (Node.js)
• Ideally React (or willingness to learn)
• Experience with building real applications (not just tutorials)
• Attention to quality (code reviews, testing, best practices)
• Ability to work across backend and frontend
• Be open-minded
• Come up with improvements and realize them
• Share your knowledge with others
• Readiness to learn new things

NICE TO HAVE:

• DevOps / SRE basics
• QA mindset
• Security awareness
• UX / product sensitivity
• Interest in AI / LLMs (not required, but we’ll expose you to it)

Fullstack dev who wants to build more than just features? Read on.
We’re building a visual-first testing platform that simplifies how apps are tested. No endless configs, no fragile Selenium logic. We’re talking real automation — and yes, we’re already looking at AI, computer vision, and LLMs to help generate tests in the future.
Behind the scenes, we run a flat team structure, we experiment a lot, and when something doesn’t work, we fix it. No middle layers, no gatekeeping.

You’d be joining early — we just silently launched alpha version of the product — with full opportunity to shape the product and how we build it.

Your toolbox (the stuff we actually need):

• Solid .NET Web Services experience (this is core)
• You’ve built REST APIs, not just used them
• You want to be part of refinements, not wait for hand-offs
• You’re curious, technically solid, and ready to grow

Your angle (what you bring on top):

No one’s perfect, but if you bring two or more of these, we’ll get excited:

• deep performance optimization and scalability experience (.NET)
• monitoring or observability know-how
• security mindset
• background or interest in computer vision / AI
• a feel for UX/UI that goes beyond dev perspective

You might also know (bonus points):

• PostgreSQL, Redis, S3
• Entity Framework, Next.js, React
• Microservices, GitHub Actions, Kubernetes, CI/CD

How we work:

• No managers
• Teams that decide together
• Code meets product meets reality
• We listen, challenge, and improve — quickly

One of our terminal-based product teams is looking for a new junior/medior teammate!
