Mechanical Design Engineer
About Base
Base is building the foundation of American power. The grid is the largest, most complex machine in the world. Yet it’s aging, struggling to keep up with today’s demand, and is unprepared for our electrified future.
Base is modernizing the grid as the first engineering-led, technology-driven power company. We’re deploying a nationwide network of distributed batteries that strengthens critical infrastructure and saves Americans money.
Our team of engineers, operators, creatives, technicians, and electricians design and deploy systems at speed. If you want to tackle the problem that will define this century and shape the future of American energy, now is the time. Join us.
About the Role
We are looking for a Mechanical Design Engineer to lead mechanical design for Base’s high power residential inverter. You’ll own key components, review others, and solve cross-functional design challenges as they come up.
This role is for someone with strong thermal fundamentals and experience designing mechanical components for power converters, including heat transfer solutions and packaging for magnetics and capacitors.
What You'll Do
Own the delivery of the best high power residential grid tied inverter.
Own mechanical design of some components, check the mechanical design of others.
Drive solutions to design problems, be the glue that fills the cracks between designers.
What You'll Bring
5+ years expertise owning mechanical design for grid tied or similar power converters.
Extremely strong thermal fundamentals, including modeling (1D, transient / steady state, FEA/CFD).
Experience designing power electronics mechanical components such as magnetics, capacitors banks, etc.
Experience designing heat transfer strategies of various types.
Our Values
We’re building a winning culture and we’re looking for people who are up for the challenge. Here’s what we expect from day one:
In-Person Only: We work full-time in the office. No hybrid. No remote.
