What are the responsibilities and job description for the Flight software engineer position at Proteus Space?
Company Description Proteus Space accelerates the spacecraft definition and Assembly, Integration & Test (AI&T) life cycle from years to months, enabling customers to field responsive space assets on radically shorter timelines. The company delivers full design packages with Hardware-in-the-Loop (HIL) validation, providing greater confidence in performance before deployment. Its approach combines transformational speed and scale with robust technical rigor, appealing to teams focused on rapid prototyping and innovation in space systems. Design specifications are supported by Government Purpose Data Rights and customer-owned deliverables, giving partners long-term control and flexibility over their solutions.
Role Description The Flight Software Engineer is a full-time, hybrid role based in Los Angeles, CA, with flexibility for some work-from-home days. This role focuses on designing, implementing, and maintaining flight software for spacecraft, including core control algorithms, communication interfaces, and fault management logic. Day-to-day activities include writing and reviewing production-quality code, integrating software with hardware-in-the-loop test environments, and debugging issues across embedded platforms and ground tools. The engineer collaborates closely with systems, hardware, and AI&T teams to define requirements, ensure reliability, and support rapid iteration on flight software architectures. Responsibilities also include contributing to internal documentation, participating in design reviews, and improving development workflows and tooling.
