About the role
Mainspring is looking for a Senior Staff Mechanical Engineer — Electromechanical to lead the design and integration of electrical enclosures, busbars, and cable systems for our next-generation energy platforms. This is a highly visible technical leadership role focused on solving difficult real-world engineering problems across power electronics packaging, harsh-environment durability, manufacturability, and system integration. You’ll help shape core product architecture while working on systems deployed across demanding operating environments ranging from coastal and desert conditions to future megawatt-scale applications. We’re looking for an engineer who understands how electrical and mechanical systems behave in the real world — and can drive robust electromechanical solutions from concept through production.
What you'll bring
- BS or MS in Mechanical Engineering or related field
- 12+ years of experience designing electromechanical hardware systems
- Proven experience designing electrical or electronic enclosures through production release
- Strong background in sheet metal design and mechanical-electrical integration
- Experience packaging electrical components such as fuses, contactors, relays, PCBAs, busbars, cables, connectors.
- Experience in designing systems such as inverters, controllers, fuse systems, batteries, or other power electronics.
- Understanding of thermal management, vibration, environmental durability, grounding, creepage/clearance, and EMI-related packaging constraints
- Experience supporting validation, testing, manufacturing launch, and sustaining engineering
- Proficiency with SolidWorks and PLM systems
- Busbar design experience
- HV power systems experience
- Cable harness and routing design experience
