Mainspring Energy, Menlo Park, CA
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.
This compensation and benefits information is based on Mainspring Energy's estimate as of the date of publication and may be modified in the future. We generally do not negotiate on salary once we have made an offer. The level of pay within the range will depend on a variety of job-related factors that may include location, relevant prior experience and/or education, or particular skills and expertise. New hires joining the company tend to be paid within the starting base pay range noted above, with opportunities to increase pay over time based on development of additional skills, competencies, and company-specific knowledge.
The Linear Generator is unlike any other generator technology on the market - it is a system that couples a chemical reaction and thermally-driven expansion directly to a linear motor for energy generation and control - called the Adaptive Pressure Cycle. This puts the controls and power electronics at the center of the design, and we’re looking for a leader who can thrive in a dynamic environment with many systems-level tradeoffs to balance.
It is important that they have a deep understanding in many of the critical areas: power electronics / motors / inverters, PCBA designs / mixed-signal routing, low-noise analog signal conditioning and high-EMI environments.
They must also have significant practical experience bringing power electronics to market, with a good understanding of high volume manufacturing and attaining high quality and reliability at low cost.
This person must be an excellent leader who personifies our core values and can grow the team to accomplish our goals. This position reports to the SVP of Engineering, and is expected to be onsite at least 60% of the time.
Mainspring Energy manufactures and delivers fuel-flexible, low-emissions local power solutions that rapidly add new capacity and deliver reliable, affordable, and sustainable electric power.
