OUR TEAM 

We’re growing in Poland with a brand-new team hub in Wrocław. As we build our local community, we’re searching for top tech enthusiasts and industry experts to join the journey. If you want to build mission-critical solutions on an impressive scale - join us! We’re a small, hands-on engineering team building the infrastructure backbone that powers AI at scale. If you like the idea of designing something from a blank page - not inheriting a legacy codebase, but actually shaping how a DataCenter-level platform works from the ground up - this is that kind of role.

ABOUT THE ROLE

• Designing and building the automation layer from scratch: Developing a DataCenter-level automation and orchestration platform for infrastructure resources from the ground u

• Managing the full resource lifecycle: Implementing end-to-end processes for infrastructure resources, covering everything from initial provisioning to returning retired resources back to the pool

• System and hardware-level Python development: Writing robust, high-performance Python code that operates close to the system and hardware layers

• API integration: Designing and building RESTful APIs and integration interfaces to seamlessly connect with diverse hardware components and IT/AI infrastructure systems

• DevOps and infrastructure orchestration: Applying solid DevOps methodologies to ensure high availability, scalability, and stability of the AI/IT infrastructure management ecosystem

• CI/CD and process automation: Building and maintaining automated testing, deployment, and continuous delivery pipelines for infrastructure management tools and services

YOU ARE A PERFECT MATCH IF YOU HAVE

• Kubernetes: Hands-on experience managing and orchestrating containerized environments

• Proficiency with Infrastructure as Code (IaC): tools like Terraform, Ansible, or CloudFormation

• CI/CD Pipelines: Experience building, maintaining, and optimizing automated deployment workflows

• Linux Administration: Deep system-level knowledge for diagnosing and troubleshooting complex OS issues

• Practical understanding of IP networking, routing, load balancing, and protocols

• Familiarity with distributed architectures, failure modes, and trade-offs

• Production Mindset: Real-world insight into how systems break differently in production versus local environments

NICE TO HAVE

• Experience with durable execution engines for long-running workflows

• Experience with OpenTofu

• Working knowledge of PostgreSQL, Ceph, and Redis

• Familiarity with Keycloak / OIDC, OpenBao / Vault, PKI, and mTLS

• Experience with OpenAPI, gRPC, and REST API design

• Ability to read Go, Rust, HCL, and TypeScript (frontend code)

• Observability: Experience instrumenting code with metrics, logs, and tracing

WHAT WE OFFER 

• Work on every layer of an AI Factory - from the hardware and the newest GPU architectures up to the software that runs training and inference, on infrastructure measured in hundreds of megawatts

• Work alongside a team of highly experienced Cloud and Infrastructure experts in building mission-critical solutions

• Collaborate with international Client and internal teams across the UK, Japan and other top-tier tech hubs

• Real impact - directly shape and influence the final design of our infrastructure, applications, and processes

• Friendly start-up culture where everyone knows each other, help is always around the corner, and regular team integration events keep us connected

• We offer full-time employment based exclusively on an employment contract

• Comprehensive private healthcare (Medicover Premium) plus affordable family packages.
