Local power generation for data centers, utilities, industrial & enterprise applications. Fuel-flexible, fast to deploy, high-efficiency, low NOx power. Backed by General Catalyst and Khosla.
About the role
Mainspring is seeking a Mechanical Engineer to own defined-scope mechanical engineering tasks, workstreams, or moderate-complexity projects for our Linear Generator platform. In this role, you will design mechanical hardware, support analysis and testing, drive assigned work through validation and release, and work cross-functionally with engineering, manufacturing, quality, supply chain, test, and service teams.
What they're looking for
- BS or MS in Mechanical Engineering or a similar engineering field, with demonstrated experience contributing to mechanical design work beyond purely academic projects
- Experience designing, analyzing, testing, and iterating mechanical hardware through multiple project phases or design cycles
- Ability to independently own defined-scope engineering work with clear deliverables, while seeking guidance for ambiguous, complex, or high-risk decisions
- Strong mechanical fundamentals, including practical experience with parts, assemblies, fixtures, mechanisms, structures, thermal systems, fluid systems, electromechanical packaging, or other relevant mechanical systems
- Demonstrated ability to use analysis, testing, data, and engineering judgment to evaluate designs, compare options, and recommend practical next steps
- Clear communication and execution skills, including the ability to document assumptions, decisions, risks, test results, and project status for technical and cross-functional stakeholders
