Sr Systems Integration Engineer - Electrical

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 Functionally reporting to the Systems Engineering Department and deployed directly to a satellite program, you will oversee the electrical integration, harnessing, powering, and testing of spaceflight hardware. You will ensure that power, data, and RF subsystems interface flawlessly, manage the Electrical Interface Control Documents (EICDs), and guide the spacecraft safely from a collection of boards to a fully functional, integrated system ready for launch.

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.
