## Description

They are now looking for a Principal Flight Software Engineer to act as technical leader for spacecraft flight software on this programme. This is a small, high impact team building many systems from scratch, working in a fast-iteration environment where requirements evolve and engineers own real subsystems rather than a slice of one.

What you'll be doing:

 * Acting as technical leader for spacecraft flight software, from architecture through to in-orbit operations
 * Writing embedded C code from scratch for real-time command and control of the satellite
 * Working within the NASA cFS (Core Flight System) framework
 * Reviewing code and system designs, and analysing code for efficiency, stability and scalability
 * Hands-on development and troubleshooting of software systems and hardware, including motors and power distribution units
 * Supporting software quality assurance and optimising I/O performance
 * Supporting integration, test and mission operations
 * Working closely with GNC, hardware and mission operations teams
 * Assessing third-party and open-source software for use across the platform
 * Presenting design review material to customers and the executive team, and contributing to proposal-writing efforts
 * Mentoring junior engineers and acting as a subject matter expert across the software team
