Firmware Engineer

Company Details

Making Space for everyone.

Come be a part of the 21st Century Space Race. At Firefly, we are focused on the leading edge of space systems progression. Our company is committed to providing economical and convenient access to space for small payloads through the design, manufacture, and operation of reliable launch vehicles and spacecraft. To get there, we are looking for incredibly passionate, bright, and determined people to join our team.


The Firmware Engineer will be responsible for the integration and test of the firmware found on all of Firefly’s Avionics and Avionics sub-systems. This role is part of a growing firmware team and is an opportunity to learn and grow. The candidate will have the opportunity to test, optimize, and maintain FPGA firmware systems on multiple platforms related to both traditional launch vehicles, and spacecraft.

This is a fast-paced role requiring the ability to adapt and be flexible including understanding PCB assemblies’ function in the overall system and build the firmware configurations to meet the requirements. A successful candidate will be a team player able to support the firmware and FPGA performance from development through launch.
