Lead Platform Engineer (m/f/d)

Our platform is based on a modern, open-source-driven stack with a strong focus on reproducibility, security, and efficiency:

Nix & NixOS -- our foundation for reproducible builds and declarative system configuration
Rust -- our lingua franca for systems and backend development
Terraform -- infrastructure as code
OpenTelemetry -- for standardized observability
Grafana's LGTM stack (Loki, Grafana, Tempo, Mimir)
GitLab -- as our central DevOps tooling
OpenStack -- our private cloud infrastructure
Kubernetes & GitOps - our runtime and delivery infrastructure

• Design, build, and evolve our Internal Developer Platform (IDP) as a self-service platform
• Integrate a transparent Secure Software Development Lifecycle (SSDLC)
• Develop and maintain golden paths, templates, and standardized pipelines for developer teams
• Implement and enforce policy-as-code, security gates, and reproducible build pipelines
• Operate and enhance the platform infrastructure (CI/CD, observability, secrets management, deployments)
• Collaborate closely with development, security, and operations teams
• Own the "Developer Platform" product -- including roadmap planning, feedback loops, and key metrics

• Several years of experience developing and operating modern developer platforms or DevOps toolchains
• Deep understanding of build systems, CI/CD, infrastructure-as-code, and observability
• Experience with Nix/NixOS is a strong plus -- or a strong desire to learn
• Rust knowledge is beneficial (not mandatory) since many of our tools are developed in Rust
• Python and Go is beneficial and familiarity with DevSecOps methodology are helpful
  Familiarity with modern software security lifecycle standards (e.g., SBOMs, SAST, DAST, IAM, ...)
• Product-oriented mindset, ability to work autonomously, and pragmatic problem-solving skills
• Strong communication skills -- able to gather requirements from dev teams and translate them into platform features 

• The opportunity to build a platform from the ground up that truly empowers developers
• Work with an exceptionally modern tech stack (Nix, Rust, OpenTelemetry, etc.)
• Collaborate with experienced engineers in a technically excellent environment
• Clear vision, lots of freedom to shape your work, and real impact potential
• Flexible working hours, remote options, and modern equipment
