Senior Full Stack Engineer - Government Solutions

About the role

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. This is a zero-to-one role: part prototyping, part systems design, part integration engineering—all impact. You'll work across the full product lifecycle, from rapidly building and iterating on prototypes, to integrating with existing platforms and external partners, to establishing the architecture and engineering practices that will support long-term growth.

What you'll do

• 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.
• 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.
• Contribute across the stack—from backend services and APIs to frontend interfaces—ensuring a cohesive and usable end-to-end experience.

What you'll need

• 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.

Nice to have

• Experience working in early-stage or zero-to-one product environments.
• Experience with modern web frameworks (e.g., React, Node.js, FastAPI, or similar).
• Understanding of data pipelines and working with data-intensive applications.
• Familiarity with geospatial data or Earth observation.
• Exposure to AI/ML-driven products and integrating model outputs into applications.

What they offer

• Flexible working hours and hybrid work model.
• Not an overtime culture — overtime offset with time off and rest.
• Frequent internal workshops, knowledge sharing sessions, journal clubs and hackathons.
• Potential to participate in the employee stock option program.
• Urban Sports membership, BVG subsidy, and corporate pension program.
• Office in the centre of Berlin Kreuzberg with free fruit, nuts and drinks.
