Lead Satellite Propulsion Mechanical Engineer

Socket.dev; Burlingame (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Xona is seeking a Sr. Mechanical Engineer to join the propulsion team in Burlingame.

You will serve as the primary mechanical architect and design owner for advanced satellite propulsion hardware, driving core mechanical and thermal design from early architecture concepts through prototype stage iteration, qualification testing, and transition to high-rate flight production. This is a high-ownership, hands-on role where you will drive full-system CAD development, detailed FEA, thermal-structural

Qualifications

• Bachelor's or Master's degree in mechanical engineering or a related field.
• Experience leading mechanical hardware design from concept through prototype and production.
• Strong Design for Manufacturability and experience working with machinists and vendors.
• Expert-level GD&T and tolerance analysis (ASME Y14.5).
• Materials knowledge including refractory metals and ceramics and heat treatment.
• Proficiency with CAD (SolidWorks) and FEA for structural and thermal analysis.
• Prototyping-first mindset and ability to build/test your own hardware.
• Strong problem-solving and attention to detail.
• Ability to work collaboratively with multidisciplinary teams.

Responsibilities

• Serve as the lead designer for the propulsion system and supporting hardware.
• Drive Design for Manufacturability (DFM) across several high-precision mechanical components and assemblies working directly with machine shops and specialty vendors.
• Select materials for high-temperature, high-vacuum, and other demanding environments and define standards and material treatments.
• Perform structural and thermal analysis to evaluate margins and ensure survival under launch and operational environments.
• Build, assemble, and iterate on prototype hardware, and support integration into TVAC facilities.
• Develop and execute test plans for prototypes, engineering models, and flight hardware, and troubleshoot mechanical assemblies in the lab.
• Define inspection, acceptance, and assembly procedures that carry the design from prototype into sustained production.
• Support supplier evaluation and selection for mechanical and thermal components.
