Senior Full Stack Engineer (f/m/x) - Government Solutions

We are looking for a Senior Full Stack Engineer to lay the technical foundations of a new product within our Government team, shaping it from early prototypes to a scalable, production-ready solution in the defense and security domain. The role involves working across the full product lifecycle with TypeScript and Python, collaborating with internal teams and external partners including the German Armed Forces.

• Rapidly design and build end-to-end prototypes (TypeScript & Python), translating ambiguous requirements into functional, testable systems that validate product direction.
• Define and implement integrations with existing platforms and services (internal and external), ensuring clean interfaces, reliable data flows, and extensibility for future development.
• Collaborate across teams to reuse and adapt existing components, aligning on architecture, APIs, and shared standards while bridging gaps between systems.
• Take ownership of early architectural decisions (service boundaries, data models, deployment patterns), balancing speed of iteration with long-term maintainability.
• Iterate quickly based on feedback from stakeholders and partners, evolving prototypes into more robust solutions and identifying what should transition into production systems.
• Work closely with external partners to prototype integrations and validate interoperability in real-world environments.
• Establish best practices for prototyping and early-stage development (code quality, documentation, lightweight testing), creating a foundation for future engineering efforts.

• Strong engineering fundamentals in TypeScript and Python, with a focus on writing clean, maintainable, and well-structured code.
• Experience building full stack applications, including backend services, APIs, and modern frontend interfaces.
• Proven ability to rapidly prototype and iterate on products, translating ambiguous requirements into working solutions.
• Experience designing and implementing integrations between systems (APIs, data pipelines, third-party services).
• Familiarity with cloud platforms (e.g., AWS, GCP) and deploying scalable services.
• Solid understanding of software architecture and system design, with the ability to make pragmatic trade-offs in early-stage environments.
• Experience working in collaborative, cross-functional environments and aligning with multiple stakeholders.
• You take ownership and proactively push work forward.
• You communicate clearly and collaborate smoothly both within and across teams.
• Pragmatic mindset: You balance deep research with practical delivery.
• You enjoy working with complexity and turning ambiguity into structure.
• Willingness to work on-site in Berlin and eligibility to obtain a German security clearance (Sicherheitsüberprüfung).
