Fortastra designs and delivers resilient, high-performance spacecraft that safeguard critical orbital assets and ensure freedom of action in space. We integrate advanced autonomy, sensing, and control into systems engineered for reliability, speed, and scale.
Our culture values simplicity, accountability, and disciplined execution — empowering every engineer to think systemically, act decisively, and build with purpose. Aggressive innovation. Disciplined execution.
Strength among the stars.

You will join Fortastra’s Engineering Division, responsible for the design, development, and test of flight systems across our autonomous spacecraft portfolio.

We are seeking an experienced Avionics Integration Engineer to join our growing team in Torrance, CA. This is a hands‑on, onsite position (no hybrid or remote option). You will work directly with multidisciplinary engineering teams to design, integrate, and validate flight systems supporting proximity operations, autonomous maneuvering, and mission‑critical aerospace applications.

• Lead hardware/software integration for spacecraft avionics subsystems including flight computers, sensor packages, and communication modules.
• Develop and maintain interface control documents (ICDs) and ensure seamless integration between avionics, GNC, and power systems.
• Design and execute verification and validation plans for embedded and networked avionics components.
• Collaborate with software, mechanical, and electrical teams to troubleshoot and optimize system‑level performance.
• Conduct bench and environmental testing of integrated avionics hardware prior to flight qualification.

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related discipline.
• 5+ years of experience in avionics systems development, hardware/software integration, and test.
• Proficiency with embedded systems, serial buses (CAN, SPI, I2C), and data acquisition systems.
• Experience with C/C++, Python, and Linux‑based development environments.
• Strong understanding of system bring‑up, configuration management, and verification processes.
• Experience with radiation‑tolerant hardware and fault‑tolerant architectures.
• Familiarity with flight software frameworks such as cFS or custom RTOS implementations.
• Hands‑on experience with oscilloscopes, logic analyzers, and avionics test equipment.
• Knowledge of space or defense program requirements (MIL‑STD‑1553, DO‑160, ECSS).
• Work is onsite; remote or hybrid arrangements will not be considered.
• U.S. Citizenship and ability to obtain or have an active TS/SCI clearance.

Join a small, high‑impact team developing the next generation of autonomous orbital control systems for national security space. At Fortastra, engineers own the full lifecycle — from concept through flight — shaping the future of trusted, resilient spacecraft autonomy.
