Senior Flight Software Engineer Seen this week
Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.
We are seeking a highly motivated Senior Flight Software Engineer to join our mission-driven team developing Nyx. In this role, you will take full ownership of key components of the flight software stack. You will be designing, implementing, and testing mission-critical systems that enable safe, autonomous, and reliable spaceflight operations.
You will work in a fast-paced, collaborative environment where cross-functional integration is essential. Your code will interface directly with vehicle avionics, guidance systems, propulsion, communications, and ground control. Expect to write modern, high-reliability C++ and Python code, drive software simulations, and ensure flight readiness through rigorous testing at both unit and system levels.
*Applications at all seniority levels are considered.
Key Responsibilities
Design, implement, and own core flight software modules for spacecraft control, telemetry, data handling, fault management, and communications.
Develop in modern C++ and Python for support tooling, following best practices in software architecture, testing, and performance optimization.
Build and maintain test frameworks for automated unit, integration, and hardware-in-the-loop (HIL) testing to validate software behavior across mission phases.
Create and run high-fidelity simulations to model flight dynamics, subsystem interactions, and edge cases.
Collaborate closely with GNC, avionics, propulsion, and mission operations teams to ensure seamless integration and mission success.
Participate in code reviews, design reviews, and flight readiness assessments.
What we would love to see from you
Strong proficiency in modern C++ (C++17 or newer) and Python.
Experience with real-time systems, embedded development, or spacecraft software.
Demonstrated ability to take ownership of complex technical problems and drive them to resolution.
Familiarity with software testing methodologies and simulation tools.
Excellent cross-disciplinary communication and collaboration skills.
Good understanding of math & physics.
Focus on detail, quality, and testing.
Experience with CI/CD systems and build systems.
Nice to have
Knowledge of safety critical and real-time critical software and familiarity with RTOS.
Good understanding of communication protocols such as: TCP/IP, UART, CAN Bus and serialization.
Experience with automotive or flight software frameworks.
Background in orbital mechanics, spacecraft systems, or space mission lifecycle.
Experience with industry standards such as AUTOSAR, ECSS, DO-178.
Why you should join us!
What makes us special here at The Exploration Company and why we think you will enjoy working here is:
We’re Agile - we make decisions fast whilst keeping our goals and systems in mind
We’re Open and Collaborative - we are transparent about risks and obstacles, so that we can cooperate to overcome them
We have a lot of Fun - we refuel our energy knowing we are democratising space. It’s a wonderful and rare opportunity, are YOU up for the challenge?
