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 Principal Mechanical Engineer role focuses on applying advanced technical principles, theories, and concepts to engineering projects, as well as contributing to the development of new principles and concepts. The position involves leading projects or significant aspects of a program, developing and implementing innovative solutions, and working under consultative direction toward long-range goals and objectives. Responsibilities include collaborating with cross-functional teams, analyzing and interpreting data, preparing detailed technical documentation, and mentoring junior engineers. This role is critical in driving innovation, ensuring successful project execution, and supporting the overall mission of the organization.

In this role, you will lead design and analysis efforts for multiple programs and complex design activities, which may include serving as a Responsible Engineer (RE). You will manage all aspects of system and component design, development, and integration, including trade studies, layouts, architecture definition, system testing and verification, and troubleshooting. By applying advanced technical principles, theories, and concepts, you will contribute to engineering projects, utilizing data analysis and interpretation skills to evaluate test and simulation data, inform design decisions, and identify areas for improvement. You will interact with senior personnel across the organization on significant technical matters and prepare detailed technical documentation and reports to communicate findings and support project objectives. Representing the organization as the prime technical contact on contracts and projects, you will work under consultative direction toward predetermined long-range goals and objectives. Additionally, you will contribute to the development of new principles and concepts, driving innovation within the organization, and develop and implement innovative solutions and rigorous analyses to address complex technical challenges. Mentoring junior engineers and providing guidance on their technical and professional development will be an integral part of your responsibilities. Furthermore, you will collaborate with cross-functional teams to develop and refine system designs, ensuring they meet performance and safety requirements.

  • Experience with spacecraft Electrical Power Systems (EPS) and solar array technologies, including power generation, distribution, and management systems
  • Proven track record in high-volume manufacturing environments with demonstrated ability to implement Design for Manufacturability (DFM) principles to spacecraft systems

Compensation:

Pay Range:
$167,096.00 - $229,757.00
