About The Position

Overview Energy is a mission-driven team committed to delivering Space Solar Energy to the world. We operate at the intersection of space infrastructure and energy abundance, providing continuous baseload power 24/7 - without seasonality or the need for batteries. Headquartered in the Northern Virginia / Washington, DC area and backed by world-class investors, we are advancing the next generation of clean energy technology. About the Role We're looking for an Embedded Software Engineer to help develop the flight and payload software that powers next-generation satellites. You'll contribute across the space software stack — from bare-metal firmware and RTOS applications to ground systems — writing reliable code for size-, weight-, and power-constrained hardware. Your software won't sit on a shelf: expect to see it on orbit within weeks and months, not years. This is a hands-on role for someone early in their career who is excited to grow at the intersection of software and hardware in high-consequence, harsh operating environments.

Familiarity with CI/CD tools and version control workflows

Responsibilities

Write and test embedded software for microcontrollers in C/C++ using RTOS and/or embedded Linux
Interface with satellite electronics via common protocols including RS-422/485/232, SPI, I2C, GPIO, and UDP/TCP
Support the development of hardware drivers for spacecraft sensors and actuators
Build and maintain Python-based test and automation scripts for payload hardware
Develop and execute unit tests, and contribute to system-level, PIL, HIL, and SIL test efforts
Support CI/CD pipelines for satellite development and flight systems
Contribute to Ground Software and Mission Operations tooling
Participate in design reviews and collaborate with systems and hardware engineers to develop and validate requirements
Write and review code daily, ensuring adherence to coding standards — this is a builder's role
