Senior DevOps Platform Engineer

The enterprise is going agentic and we are creating a unique operating system for an automated future.

Most AI agents break the moment they hit real business complexity. Thats why we built a platform that models a companys policies workflows and operational logic into an AI Data Model. Shelf enables AI Agents to reliably reason and deliver precise and reliable outcomes at scale.

We already have what most AI startups are still trying to earn: Enterprise customers such as Glovo Nespresso and HelloFresh real production data and tens of thousands of users. Customers trust us with operational knowledge: Our platform is highly reliable and secure with SOC2 HIPAA-ready security practices and mature integrations in place.

Location Warsaw work from the office.

This role is for a senior DevOps / platform engineer who can own the AI platform infrastructure that lets Shelf teams ship agentic AI capabilities quickly safely and reliably.

We want someone who is strong technically operationally mature communicates clearly and has the judgment to make infrastructure simpler safer and easier to evolve over time. Expect real ownership from platform design through production operations.

You will own the platform layer behind model access model deployment observability reliability security and developer experience. That includes our internal AI gateway cloud-hosted models self-hosted models VLMs audio models and the runtime paths product teams need to build production AI systems.

The team is small enough for platform engineers to make real decisions. Career growth comes from ownership. Titles matter less than the scope you can carry. The people who grow fastest take responsibility for larger systems unblock product teams drive reliability and develop better engineering practices.

You solve ambiguous platform problems by shaping the right operating model then ship automate instrument and keep it healthy in production.

We build AI-native. Engineers use Codex Claude Code and agents they build themselves. We invest in harness engineering through skills CLIs logs traces and this role you use that same mindset to give product teams better paths for deploying scaling observing and securing AI workloads.

This is a role for someone in a high-growth chapter of their career who wants to do the best work of their life learn fast and win as part of a team going all-in on a hard mission.

• Own Shelfs AI platform infrastructure end to end: model access model deployment runtime paths observability reliability security and developer experience.
• Build and operate the internal AI gateway and the platform services product teams use to ship AI capabilities.
• Enable teams to use cloud-hosted and self-hosted models safely including LLMs VLMs audio models and other AI runtimes.
• Improve deployment scaling monitoring and incident response for AI-heavy production services.
• Build infrastructure as code CI/CD flows environment setup and paved paths that reduce developer friction.
• Strengthen logs metrics traces dashboards alerts and service-level visibility so teams can understand their systems earlier.
• Improve security and access control around models secrets permissions auditability and production operations.
• Reduce recurring toil through automation internal tools runbooks and better defaults.

• Product teams ship AI capabilities faster because the platform gives them clear reliable paths.
• More models and runtimes become production-ready without each team inventing its own infrastructure.
• Teams have better visibility into their services and can catch reliability problems earlier.
• Deployment observability access control and incident response become calmer and easier to operate.
• The systems you touch become simpler safer and easier to evolve.
• You create momentum without waiting for detailed instructions.
• You handle production issues with maturity and improve the system after the immediate problem is solved.

• Strong senior-level experience in DevOps platform engineering SRE infrastructure engineering or a similar hands-on role.
• Strong cloud and infrastructure fundamentals in AWS GCP or Azure.
• Real experience with infrastructure as code and modern delivery pipelines.
• Strong operational judgment around reliability observability incident response and production systems.
• Comfort moving across layers: infrastructure backend services AI runtimes developer workflows and operational tooling.
• Security-minded approach to platform work: access control secrets permissions auditability guardrails.
• Clear communication and strong written habits especially around runbooks postmortems and technical decisions.
• AI-native working style. You already use AI tools in daily engineering work and think in terms of leverage automation and better workflows.

• Experience deploying or operating model-serving infrastructure model gateways or AI platform services.
• Experience improving developer experience for product engineering teams.
• Experience with GCP.
• Ability to debug problems that cut across application code infrastructure and third-party systems.

We evaluate fit through ownership systems judgment production maturity and your ability to make complex platform work usable for product teams. Strong candidates can step into an ambiguous AI platform area identify the highest-leverage gaps ship practical improvements and make the system faster safer and easier to operate.

• B2B contract
• Company stock options
• Hardware: MacBook Pro
• Modern technical stack develop open-source software
• A strong AI-native engineering environment with modern tools and room to experiment including Claude Code OpenAI Codex and GitHub Copilot
