Lead Mechanical Engineer

About the role

We're hiring a hands-on mechanical engineer to join our team building space hardware systems, working across multiple disciplines. In this role, you'll take real flight hardware from concept to delivery, focusing on mechanical design while integrating with electrical systems and software. While you should be experienced with mechanical design, this isn’t a narrow specialist role; we are seeking a generalist who sees the big picture, moves fast, and thrives on solving a new problem every day.

What you'll do

• Mechanical Design & Analysis: Create detailed mechanical designs using SolidWorks, apply GD&T standards per ASME Y14.5, and conduct tolerance stackup analysis
• Lifecycle Systems Engineering: Design new parts and systems from first principles to meet goals. Support performance specification definition, verification planning, and technical documentation throughout the product lifecycle.
• Project Support: Collaborate with multidisciplinary teams, manage vendor relationships, and provide technical and hands-on support for manufacturing and assembly processes in San Francisco and at customer facilities.
• Cross-Domain Engineering (Land/Air/Sea/Space): Conceive, design, develop, build, test, and deploy engineered systems for extreme environments with an emphasis on space.

Qualifications

• Education: Bachelor's degree in Mechanical Engineering, Mechatronics Engineering, Aerospace Engineering, or related technical field.
• Experience: 3+ years of professional experience in mechanical design, preferably in aerospace, ocean, robotics, or similar.
• Technical skills:

-

• Proficiency in 3D CAD (SolidWorks Preferred)
• Knowledge of GD&T per ASME Y14.5 and tolerance analysis
• Knowledge of best design practices for mechanical parts
• Experience with common prototyping and manufacturing processes and their limitations

• Preferences:

-

• Expeditionary mindset: you have the curiosity and drive to ask big questions about the natural world and deploy systems to extreme environments to answer those questions
• Experience with space systems, satellites, or aerospace hardware development
• Experience performing FEA
• Experience with environmental testing and standards (e.g. NASA GEVS)
• Hands-on experience with laboratory equipment in a clean room environment
• Previous start-up work experience

What We Offer

• Equity participation, healthcare, flexible PTO, and professional development opportunities.
