Builder & Problem Solver

About Tobe Energy

Industry runs on hydrogen - 94 million tonnes a year go into fertilizer, fuel, food, pharmaceuticals, and steel, and 99% of it is made from fossil fuels. Tobe Energy is building the machine that changes that: an isothermal electrolyzer driven by a pulsed waveform architecture that hits >92% system efficiency, runs below 30°C with no active cooling, and is built from commodity materials (zero rare earths) with 95% U.S.-sourced manufacturing right here in Oklahoma City.

We're a small team moving fast. Everything we ship, we first design, print, machine, wire, plumb, and break in our own shop.

The Role

This is not a job with a fixed lane. One week you might be assembling and pressure-testing a membrane cell; the next you're wiring a power electronics test stand, tracking down a leak, machining a fixture, or running an experiment overnight and telling us what the data means. As a startup, the role will change day to day, sometimes hour to hour, and we need someone who treats that as the fun part.

We don't care whether you have a degree. We care whether you can figure things out, work safely around electricity and pressurized gas, and build things that work with your hands.

What You'll Do

• Build, assemble, and test prototype electrolyzer cells, stacks, and test stands - mechanical assembly, plumbing/fittings, gaskets and seals, leak and pressure testing
• Wire and troubleshoot electrical systems: DC power distribution, instrumentation, sensors, data acquisition, soldering and harness-building
• Run experiments: set up tests, log data carefully, notice when something looks wrong, and chase down why
• Fabricate parts and fixtures using 3D printers (FDM and resin), hand tools, and shop equipment; help with light machining
• Diagnose failures - electrical, mechanical, chemical - and propose fixes instead of waiting to be told
• Keep the shop safe and organized, and help write down what we learn so we don't learn it twice
• Whatever else the day demands - inventory runs, vendor calls, packing a demo unit, holding the flashlight

Who You Are

• A self-starter. You see a problem and start working it. You'd rather attempt, fail, and adjust than wait for instructions.
• Electrically intelligent. You understand voltage, current, and power at a gut level. You can read a schematic, use a multimeter and oscilloscope, and respect what high current can do. Formal training or hard-won garage knowledge - both count.
• A critical thinker. When something doesn't work, you form a hypothesis, test it, and rule things out methodically. You ask "why" until you hit bedrock.
• Good with your hands. Wrenches, wire strippers, soldering irons, calipers, printers, saws — you're comfortable making physical things and making them well.
• A fast learner. Much of what we do hasn't been done before, so nobody's an expert yet. You pick up new tools, software, and concepts quickly and without ego.
• Flexible. Priorities shift when a prototype fails or a customer calls. You adapt without losing momentum or attention to detail.
• Safety-minded. Hydrogen, oxygen, electrolytes, and serious DC current share our shop. You follow procedures and speak up when something looks sketchy.

Nice to Have (Not Required)

• Experience with electrolyzers, fuel cells, batteries, plating, or other electrochemical systems
• CAD experience (we use Fusion 360) or willingness to learn it
• Power electronics exposure: power supplies, MOSFETs/drivers, PWM, switching circuits
• Basic scripting or data analysis (Python, spreadsheets, anything that turns logged data into answers)
• Welding, machining, or plumbing/pipefitting experience
• Prior startup, farm, military, motorsports, or trade background, anywhere you learned to fix what's in front of you with what's on hand

What We Offer

• Ground-floor role at a funded hardware startup attacking a $226B market
• Direct, daily impact - your work goes into real machines, not a backlog
• Learn across disciplines: electrochemistry, power electronics, fabrication, and test engineering, side by side with the founders
• Competitive pay based on experience

How to Apply

Email [email protected] and copy [email protected] with:

1. A short note on why this role fits you (a resume is welcome but optional),

2. Something you've built. Photos, a video, a repo, a repair story - anything that shows how you think and work with your hands. This matters more to us than credentials, and

3. Your answers to the two items below.

Did You Actually Read This Far?

Attention to detail matters in a shop full of hydrogen and high current, so here's a quick check:

• Put the word "isothermal" somewhere in your email subject line.
• Answer this in your note (show your reasoning - clear thinking beats a perfect number): Our stack has 10 cells in series, each running at 2 volts and 100 amps. How much total power is the stack drawing? And if 92% of that becomes hydrogen, roughly how many watts are lost as heat?

Applications that skip these go to the bottom of the pile.
