Job description

Overview Energy is building a mission-driven team committed to delivering space-based solar power to the world. We uniquely operate at the intersection of space and clean energy. We are based in the DC area, backed by world-class investors, and are operating in stealth mode.

Are you energized by the challenge of building both software systems and teams? As a systems programmer Senior Software Engineer at Overview Energy you will write mission-critical code while helping establish 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 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.

Responsibilities:

• Design and build well-structured, maintainable Python-based code for interfacing sensors and actuators to microprocessor and microcontroller systems.Develop a framework for continuous integration, delivery and deployment across satellite development and flight systems

• Develop embedded software for microcontrollers in a systems programming language 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 testbeds

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

• Write and review code and participate heavily in hands-on development

• Participate in the entire software development lifecycle, from design through automated and manual testing and deployment

• Mentor a high-performing software team while supporting our hardware engineers in their development efforts and tests

• Foster a culture of open communication, continuous learning, and technical excellence

Requirements:

• US Persons only. No visa applicants should apply.
