We're looking for a Hardware Integration Engineer to own the execution of hardware integration - taking released subsystem designs and turning them into validated, flying prototypes, while our specialist engineers stay focused on their disciplines. This is a deeply hands-on engineering role, not a project management or people management position: you'll work across Mechanical Engineering, Electronics, Embedded Software and Flight Test to ensure complete UAV systems are integrated, debugged, validated and ready for flight, combining practical engineering with technical leadership of prototype execution.
(Senior) Hardware Integration Engineer
Munich
Full-time
Permanent employee
What we’re looking for
The day-to-day
- Own the transition from subsystem designs to complete, flight-ready prototypes.
- Lead prototype integration, hardware bring-up and multidisciplinary debugging — catching integration issues before they become flight test problems.
- Stay hands-on across disciplines: PCB modifications, interface boards and wiring harnesses; mechanical prototype components and fixtures; hardware debugging, assembly, rework and rapid prototyping; and embedded bring-up and validation where required.
- Act as the primary Hardware Engineering interface to Flight Test — preparing aircraft for testing, making sure tests answer the right engineering questions, supporting investigation of hardware issues, and driving engineering improvements from the results.
- Build tools and methods that improve hardware development, including board validation firmware, test automation, manufacturing and EOL test solutions, and engineering utilities and instrumentation.
- Own the technical execution of integrating mechanical, electronics, embedded and systems work into validated, flight-ready hardware, so specialist engineers can stay focused on their own disciplines.
You should apply if you
- Have hands-on experience integrating mechanical, electronics and embedded subsystems into working hardware — in aerospace, robotics, automotive or another hardware-intensive field.
- Are comfortable debugging across disciplines, from PCB and wiring issues to mechanical fit and embedded bring-up, rather than staying within a single specialism.
- Have experience preparing hardware for test (bench, flight or field) and turning test results into concrete engineering fixes.
- Can build your own tools and test infrastructure — firmware, automation, fixtures — rather than relying on others to provide them.
- Want a deeply hands-on engineering role, not a project or people management position.
- Communicate well across engineering disciplines and can work effectively with specialist teams without owning their subsystem designs.
Nice to haves
- Prior experience integrating hardware for UAVs or other flight-critical systems.
- Experience building test automation, board validation firmware, or end-of-line (EOL) test tooling.
- Comfortable acting as the bridge between mechanical and electrical engineering — translating between the two disciplines and driving that collaboration through to a working prototype.
What we offer
- Real impact & ownership: Shape high-tech defense systems and take responsibility from day one.
- Mission-driven environment: Work on technologies that matter for European security and sovereignty.
- Competitive package: Competitive salary, EGYM Wellpass, corporate benefits, and equity options aligned with role and level.
- Deep tech environment: Get hands-on experience with cutting-edge drone technology and real operational use cases.
- Grow fast: Steep learning curve for juniors, strategic influence and leadership opportunities for seniors.
- Startup mindset meets defence innovation: flat hierarchies, fast decisions, and space for your ideas.
- Flexibility: Flexible hours, remote options, and relocation support.
- Strong team: International, driven colleagues and a culture built on exchange, trust, and shared success.
