What you'll do
- Design and develop ground software used for mission preparation, execution, and monitoring of hypersonic systems
- Build robust, user facing applications for Linux and Windows environments that support operators and engineers during real missions
- Implement high performance C++ software with a focus on reliability, usability, and maintainability
- Develop intuitive user interfaces and workflows to visualise system state, mission data, and operational status
- Integrate ground software with simulation, test, and live system interfaces to support end to end operations
- Work closely with systems, GNC, test, and operations teams to translate mission needs into effective software tools
- Where useful, leverage UI frameworks (e.g. Qt) and mapping or visualisation SDKs to accelerate development
What we're looking for
- A software engineer with 3+ years' experience building ground or operator-facing software in aerospace, defence, or complex technical domains
- Comfortable developing user-facing applications on Linux and Windows, with an understanding of operational reliability
- Fluent in modern C++, with an instinct for performance, robustness, and clean architecture
- Someone who cares deeply about operator experience, clarity, and usability in high-pressure environments
- Experienced translating mission and system needs into practical software tools, not just features
- Pragmatic about tooling, with exposure to UI frameworks such as Qt and an interest in visualisation or mapping technologies
- Able to move quickly in a startup environment, balancing polish with delivery speed
- Motivated by building software that operators trust during real missions, not demo-only systems
- Applicants must be a EU/Nato/German citizen, and be eligible for German Security Clearance
Benefits
A mission driven environment with the opportunity to work on one of Europe's most consequential defence challenges, with direct impact on sovereign capability and security
Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow
A fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions
A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly
- High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes
