Senior Ground Software Engineer

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.

Who you are

• A Senior software engineer with 5+ 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.

What we offer

• 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.

• High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes.

• 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.

• Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
