We’re looking for a Lead Frontend Engineer (m/f/d) to take technical ownership of the user‑facing interaction layer of an embedded system operating in a security‑critical environment.

In this role, you act as the primary technical decision-maker for frontend architecture while remaining deeply hands‑on in development. You define the frontend strategy, shape the foundations for future growth and actively contribute to building an engineering team – including mentoring, onboarding and supporting additional frontend engineers as the team evolves.

The team is responsible for building the technical foundation for new product classes and long‑term platform solutions.

We contribute directly to the development of sovereign, security‑critical digital infrastructure. The systems we shape are used in high‑security public‑sector environments where control, trust, and long‑term operability matter more than speed or hype.

• Design user‑facing apps considering resource limits, security, and update constraints
• Actively contribute code and drive hands‑on development, esp. in early project phases
• Define clear interfaces and APIs with backend and system teams
• Build and grow the frontend engineering team through mentoring and onboarding
• Collaborate with central platform and engineering units by consuming and contributing shared building blocks

Your profile

• Several years of experience in frontend or user‑facing application development
• Strong hands‑on skills with modern frontend technologies and architectures
• Experience taking technical ownership and guiding architectural decisions
• Proven ability and willingness to build, mentor and develop engineers as part of the role
• Awareness of security, lifecycle and operational constraints in software development

Technologies we use:

• Nix is the glue that keeps all our software together
• NixOS is our OS of choice
• Rust is the lingua franca of our development efforts
• React is the preferred library for our web‑based UI development
• Figma for collaborative design work
• GitLab is our software development platform
• Experience with emerging technologies and DevSecOps platforms
• Familiarity with the German language, while not required, is an advantage
• Proven experience in organizational transformation or change management
