Job Description
Senior NixOS, DevOps Engineer
virtual7 GmbH
• As a Senior NixOS / DevOps Engineer (m/f/d), you will support our clients in building modern, declarative, and highly automated software and infrastructure processes. • Consulting and implementation around Nix and NixOS: from architecture reviews and the design of modern system landscapes to the production rollout of declarative environments. • Analyze and optimize existing software architectures, source code, and development processes with a focus on quality, efficiency, and reproducibility. • Design, implement, and evolve CI/CD pipelines (e.g., GitLab, Nix Hydra), including automated build, test, and deployment pipelines. • Introduce and secure reproducible builds and modern build systems (e.g., CMake, Meson) in complex enterprise environments. • Build and maintain automated testing environments (unit, integration, and HIL tests) to ensure stable, test-driven development workflows. • Support developer and DevOps teams in adopting declarative, test- and quality-oriented working practices.
Job Requirements
- 5 years of relevant professional experience in software development, DevOps, or systems engineering
- 3 years of practical experience with Nix and NixOS in professional environments
- University degree in an IT-related field or equivalent qualification
- Strong knowledge of software architecture and software engineering — from design to production deployment
- Solid experience with DevOps practices, declarative CI, build systems, and reproducible builds
- Know-how in building automated testing environments (unit, integration, and HIL tests)
- Practical experience in at least one programming language such as C++, Rust, Haskell, Python, C, Go, or similar
- Experienced with version control (e.g., Git), containerization (e.g., Docker), and modern build tools (e.g., CMake, Meson)
- Experience establishing and advancing development and deployment processes in an enterprise context
- Ideally: experience with virtualization, microkernel-based systems, or hypervisor technologies
- Knowledge of low-level system programming (e.g., ACPI, PCI, interrupt routing, kernel modules)
- An analytical, structured, and solution-oriented working style with high quality standards, combined with independent and responsible behavior in complex technical environments
- Very good German language skills (C1 level) and conversational English.
