Mechanical Engineer

Mechanical Engineer

Full-time On-site Redwood City, CA

About the Role

We’re looking for a hands-on Mechanical Engineer with a strong background in mechanical design, prototyping, and real-world system integration.

You’ll be responsible for transforming mission-driven requirements into functional, ruggedized prototypes that perform under demanding conditions.

This is an opportunity to join a high-impact engineering team developing advanced hardware systems at the intersection of mechanics, fluidics, and electronics — built for reliability, precision, and field performance.

What You’ll Do

Design & Develop: Create compact, ruggedized subsystems, housings, and rigs in CAD optimized for reliability under shock, vibration, and environmental stress.

Prototype & Fabricate: Rapidly prototype components using CNC machining, 3D printing, vacuum/pressure forming, laser cutting, and other fabrication methods.

Integrate Fluidic Systems: Design and assemble microfluidic and airflow subsystems, including manifolds, channels, valves, pumps, and sealing interfaces.

Build Mechanical Assemblies: Develop linkages, actuation rigs, and gear trains that interface seamlessly with electromechanical and thermal systems.

Engineer for Production: Apply DFM/DFA principles, tolerance analysis, and validation testing to ensure designs scale efficiently from prototype to production.

Collaborate Cross-Functionally: Work with electrical and systems engineers to integrate mechanical, thermal, and fluidic elements into cohesive assemblies.

Test & Iterate: Travel for live demonstrations, field testing, and stress validation, capturing operator feedback to refine designs through rapid iteration.

Who You Are

Proven experience in mechanical design, prototyping, and fabrication.

Proficient in CAD/CAM tools (Fusion 360, SolidWorks) and familiar with fabrication processes such as CNC machining, 3D printing, and vacuum forming.

Hands-on experience with microfluidic systems, thermal management, or MIL-STD ruggedized design is a plus.

Strong practical understanding of materials science, mechanical tolerancing, and environmental design.

Thrive in fast-paced, hands-on engineering environments where iteration and testing drive progress.

Work Environment

Location: On-site in Redwood City, CA

Schedule: Full-time, in-person collaboration required

Culture: Small, mission-focused team that values craftsmanship, speed, and end-to-end ownership

Compensation & Benefits

Salary: $120K–$150K

Equity: Significant ownership stake

Benefits: Comprehensive coverage, flexible PTO, and opportunities to work on cutting-edge, real-world engineering challenges
