- Pragmatic Optimism
- Excellence without Ego
- Proactive Collaboration
Mainspring is seeking a Senior Mechanical Engineer to own significant mechanical engineering projects, subsystems, or technical workstreams for our Linear Generator platform. In this role, you will develop robust mechanical designs, drive projects through the full design cycle, and work cross-functionally to validate and release hardware into production or field use.
This role is intended for engineers who have already demonstrated independent ownership of meaningful mechanical design work through multiple design, test, release, or implementation cycles. A strong candidate should be able to own a significant subsystem or project area with limited day-to-day guidance, make sound technical tradeoffs, identify risks early, and drive cross-functional execution.
Candidates who are still primarily building independence on bounded tasks or single workstreams may be better aligned to a Mechanical Engineer role, while candidates who regularly improve technical decision quality across multiple projects or teams may be better aligned to a Staff Mechanical Engineer role.
Responsibilities
Qualifications
Preferred Qualifications
- What you actually built or worked on — name the real product, subsystem, or hardware (not just "components" or "systems"). "Redesigned the bracket mounting the compressor to reduce vibration failures" tells us far more than "designed mechanical components."
- What you personally did, separate from what your team did. If you contributed to a group project, tell us your specific role and contribution.
- The engineering fundamentals you applied — tie your skills (CAD, FEA, GD&T, thermal/fluid analysis, testing, etc.) to the actual problem you used them on, rather than listing them as standalone skills.
- What happened as a result — did it pass validation/testing, resolve a failure, ship to production, and if so, at what volume or scale (prototype quantity, low-rate production, high-volume manufacturing)? This helps us understand whether your experience is with one-off/prototype hardware or product that shipped at scale.
Does your experience not meet all of our posted requirements? Studies have shown that some people are less likely to apply to positions unless they meet every listed requirement. At Mainspring, we are committed to building a diverse, inclusive, flexible, and collaborative environment, so if you want to help us transition the world to clean and affordable electricity, and don’t meet all posted requirements for a particular role, we’d still love to hear from you. Mainspring can sometimes be flexible enough to shift responsibilities for the right person, or otherwise identify open or upcoming roles that may better fit your professional background.
