Electrical Ground Support Equipment (EGSE) Engineer III

About this role

Sierra Space Careers: At Sierra Space, we build the missions and systems that keep our world secure in the domain above Earth.     Sierra Space team members share a spirit of innovation and collaboration and a belief that we can deliver on the boldest missions in space today. Together with our customers, we aim to safeguard our nation, sustain human presence in space, and secure the freedom of operations in low Earth orbit and beyond.  

Our success is measured by the trust of those who rely on what we build and deliver, and our technologies keep the United States and its allies mission-ready throughout space.

We are mission-driven, and together, we are an extraordinary team.

About the Role As an Electrical Ground Support Equipment (EGSE) Engineer III at Sierra Space, you will leverage your extensive experience and general expertise in specific areas of test engineering to lead and contribute to advanced testing and validation of aerospace systems and components.

This unique position requires you to utilize electrical, mechanical, and software skills. While expertise in all three domains is not required, a basic understanding coupled with the ability to perform tasks in each area is essential.

As an EGSE (Electrical Ground Support Equipment) Engineer at Sierra Space, you will create custom test systems that provide critical functions for an array of products. These include power systems supporting the Dream Chaser from test through launch and landing, as well as communications test racks used on satellite flat sats.

Working with a broad range of teams, you will help define requirements, complete detailed designs, write software, and support execution. This role requires not only a diverse skill set but also the commitment to support entire test campaigns. Others will rely on your expertise regarding the electrical interfaces of vehicles and best practices for safely connecting equipment.

The ideal candidate demonstrates a willingness to learn and take on new challenges that stretch their comfort level. Tasks include collaborating with teams to understand requirements, then designing equipment that exceeds expectations. This involves selecting high-quality components (such as DAQs, power supplies, and relays), creating robust wiring designs, and integrating everything through software to create seamless operation. About You Our mission is driven by an unyielding commitment to advancing space-based technology in service of our customers and safeguarding national security. We seek individuals who are passionate about innovating beyond boundaries and relentlessly pursuing solutions that protect, preserve and empower – to join us in this critical mission.
