Mechanical Engineer

Job Description

We are seeking an experienced and driven Staff Mechanical Engineer who thrives in a fast-paced startup environment. You will take ownership of the end-to-end development of mission-critical mechanical and thermal systems, from blank-page concept through analysis, fabrication, and final testing. You will tackle extreme engineering challenges, including high-temperature systems with complex power electronic interfaces while mentoring junior engineers and driving projects across the finish line.

Key Responsibilities

• Lead the design, analysis, and manufacturing of complex mechanical and thermal hardware.
• Architect and design systems from the ground up using SolidWorks, ensuring robust application of GD&T.
• Conduct advanced structural (FEA) and thermal (COMSOL) analyses on systems operating in extreme environments (up to 1500°C).
• Design custom steel and aluminum weldments, overseeing their fabrication and quality.
• Architect and implement data acquisition (DAQ) systems and instrumentation to validate prototype performance.
• Act as a technical authority for DFM/DFA, frequently utilizing hands-on fabrication skills (welding, machining) to iterate rapidly.
• Take full ownership of project life cycles, navigating the ambiguities of a startup environment to deliver hardware on tight timelines.

Basic Qualifications

• Bachelor's degree in mechanical engineering.
• 5+ years of professional design and/or hands-on manufacturing experience.
• Prior experience in a startup or highly dynamic engineering environment.

Preferred Skills and Experience

• Master's degree in mechanical engineering or other comparable engineering disciplines. 
• Experience working with contract manufacturers.
• Understanding and proper application of GD&T.
• Experience with CAD (SolidWorks).
• Experience performing finite element analysis (FEA).
• Experience performing thermal analysis (COMSOL).
• Experience with steel and/or aluminum weldment design and analysis.
• Experience with high-temperature (up to 1500°C) system design and analysis.
• Hands-on design, design for manufacturability (DFM), and fabrication experience.
• Experience with common fabrication methods and tools (welder, router, mill, lathe, hand tools, etc.).
• Data acquisition and instrumentation experience (thermocouples, pressure sensors, electrical sensors, flow sensors, oxygen sensors, etc…).
• Demonstrated ability to drive projects to completion.
