Senior Systems Software Engineer

This client is building a mission-driven team committed to delivering space-based solar power to the world. They operate at the intersection of space and clean energy, delivering base-load power 24/7 without seasonality or the need for batteries. They are based in the Northern Virginia/DC area, are backed by world-class investors, and currently operate in stealth mode.

Are you energized by the challenge of building both software systems and teams? As a systems programmer Senior Software Engineer you will write mission-critical code while helping establish engineering excellence and best practices. You'll develop software for our hardware systems while collaborating with and mentoring other engineers. Initially, you will focus on delivering code for our record-breaking test campaign in early 2025 while helping strengthen our development practices.Following the test campaign, you'll turn your focus to helping with our future satellite flight software and its integration with hardware systems in space and on the ground. Your work will enable us to build a constellation of next-generation satellites at unprecedented affordability and scale.

Responsibilities:

Design and build well-structured, maintainable Python-based control and coordination systems for safety-sensitive optical and mechanical hardware and other subsystems

Develop a framework for continuous integration, delivery and deployment across satellite development and flight systems

Develop embedded software for micro-controllers in C++ using RTOS that interact with satellite electronics via RS-422/485/232, CAN, I2C, GPIO, SPI, LVDS, etc.

Develop test approach and test software for unit and system level validation and verification, as well as support of Processors-in-the-Loop, Hardware-in-the-Loop, and Software-in-the-Loop test-beds

Support development and implementation Ground Software and Mission Operations infrastructure especially in support of integration with broader system flight software
