What are the responsibilities and job description for the Senior Flight Software Engineer position at Stealth Mode?
About The Company
We are a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and several Silicon Valley firms. With a world-class business development & leadership team already in place, we are well positioned to capitalize on already overwhelming demand.
Job Overview
As a Flight Software Engineer, you will design and develop mission-critical software that enables the operation of advanced aerospace and defense systems. You will work closely with cross-functional engineering teams to translate system requirements into reliable, real-time embedded software, integrating with avionics hardware, sensors, and communication subsystems. This role involves contributing across the full software development lifecycle, including design, implementation, testing, and validation in simulation and hardware-in-the-loop environments. The ideal candidate is passionate about building high-reliability software that meets the rigorous safety, performance, and security standards required for defense missions.
