## About the role

Are you an innovative hardware leader who thrives on driving cutting-edge electronics from initial concept to production? Do you prefer the challenge of owning complex, low-voltage control systems and guiding cross-functional teams through technical hurdles over routine, single-phase component tweaking? Mainspring Energy is looking for a highly autonomous, intellectually curious, and influential Electrical Engineer, Electronics Design to join our core Electrical Engineering organization.

## What they're looking for

- 2+ years of experience with a Bachelor's degree, or 1+ years of experience with a Master's degree, in Electrical Engineering or a related field
- Proven hands-on experience designing, troubleshooting, and realizing low-voltage electrical hardware (e.g., DC/DC converters, relays, e-fuses, and MOSFETs)
- Proficiency with PCBA schematic capture and PCB design tools (Altium strongly preferred)
- Strong fundamentals in analog/mixed-signal design, including operational amplifiers, ADCs, and hardware filtering (anti-aliasing, bandpass, etc.)
- Experience performing component derating analysis, worst-case tolerance stack-ups, and Design Failure Mode and Effects Analysis (DFMEA)
- Demonstrated ability to drive projects forward from initial requirements through production
