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

The Mechanical Technician III position involves leading the assembly, testing, and maintenance of advanced mechanical systems and components to meet required specifications. In this advanced role, you will work closely with engineers and lead technicians to ensure the quality and reliability of flight hardware. This position requires an advanced understanding of mechanical principles, troubleshooting skills, and a commitment to precision and safety. You will be involved in assembling major structures, performing part-fitting operations for spacecraft systems, and translating blueprints into mechanical assemblies. Additionally, your tasks will include precision drilling, using calibrated tools, bonding, troubleshooting, and developing expert skills in precision cleaning and handling mechanical hardware.

In this role, you will mentor less experienced technicians in complex mechanical assemblies, soldering, harness routing, inspection, in-process testing, precision cleaning, and structural fabrication. You will inspect, assemble, integrate, and operationally check flight hardware, as well as assemble, test, and maintain mechanical systems and components to meet specifications and standards. Using high-precision measurement tools, you will ensure components meet specified tolerances while adhering to general best shop practices, including PPE and shop safety requirements. Additionally, you will follow 5S, FOD, and ESD awareness protocols, lift and carry up to 50 lbs, climb ladders, stairs, and work in restrictive spaces. Collaboration with team members to achieve production goals will also be a key part of your responsibilities.
