Lead Platform Engineer (m/f/d)

Secunet Security Networks AG

Jobbeschreibung

The Software Factory is secunet's innovation program, designed to provide the technical means to develop entirely new product classes. We are building an Internal Developer Platform to standardize our Secure Software Development Lifecycle (SSDLC) and significantly improve developer experience. As a Platform Engineer, you will take technical and conceptual ownership for designing, building, operating, and evolving this platform. You will create a secure, highly automated, and productivity-enhancing environment for our developers — focusing strongly on infrastructure-as-code, observability, security, and self-service.

Our Tech Stack

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

If you are keen to work for a leading company of cyber security in a fair and trusting environment, you should immediately get in touch with us.
