Senior Mechanical Engineer

About BurnBot

Wildfire has stopped being a season. BurnBot builds the machines that get ahead of it — remotely operated systems that apply and contain prescribed fire, and platforms that clear heavy fuel on terrain that isn’t safe for crews.

Our fleet is at work today for PG&E, CAL FIRE, the U.S. Forest Service, Caltrans, fire districts, and tribal nations across California, Oregon, and Washington — treating land at up to 40x the pace of conventional methods. We’re roboticists, engineers, and career fire practitioners. Hardware we design in South San Francisco is in the dirt within weeks, and the people who designed it are usually standing next to it.

THE ROLE

Our ground machines do the heavy work: applying and containing prescribed fire, and chewing through fuel loads on slopes where crews shouldn’t be. They run hot, dirty, and remote, and they have to keep running.

You’ll own major mechanical systems on those platforms end to end — concept, analysis, detail design, build, and the field failures that teach you what you got wrong.

WHAT YOU’LL OWN

• Platform-level mechanical systems: chassis and weldments, drivetrain, hydraulics, implements, and the structures that live next to active fire
• Make-versus-buy. Off-highway and agricultural suppliers already solve some of this well. Knowing when to buy and when to build is a big part of the job.
• The trades that matter most to us, roughly in this order: cost, weight, capability, and how easily a crew can run and fix it in the field
• Detail design and release: your own models, weldment drawings, tolerance stacks, and GD&T, plus the vendors and shops that build them
• Durability. Heat, vibration, abrasive dust, and 12-hour shifts. You’ll set the test program and own what comes back from it

NICE TO HAVE

• Hydraulic system design, or mobile machine controls integration
• High-temperature materials, thermal barriers, or combustion-adjacent hardware
• Time at an off-highway, agricultural, or construction equipment OEM
• Welding, machining, or fabrication in your own hands
• Wildland fire, forestry, or land management background

HOW WE WORK

• Based onsite in South San Francisco — design, build, and test all happen in one building, and being near the machines is most of the point
• Flexible within that. You own your calendar: work the hours where you’re sharpest, and go remote on heads-down days.
• Expect a few days a month in the field across California, Oregon, and Washington. Watching your work run on a live burn is the best part of the job.

COMPENSATION & BENEFITS

Base salary: $150,000 – $200,000 — final offers reflect experience and demonstrated scope.

• Equity — Incentive Stock Options
• Health, dental, and vision
• Flexible paid time off
