Senior Mechanical Engineer

HorseShoe Beverage Company; South San Francisco (CA); On-site; USD 150,000 - 200,000; Full time

Job summary

BurnBot is seeking an experienced mechanical engineer to own the major platform-level systems used on our remote fire suppression machines. You will guide concept through build, and directly address field failures that improve reliability and safety in harsh environments.

You will collaborate with suppliers, in-house teams, and field crews to optimize chassis, hydraulics, and structures. Onsite work in South San Francisco with occasional travel to field sites across the West Coast is required.

Qualifications

• Platform-level mechanical systems experience (chassis, weldments, drivetrain, hydraulics) and field-ready designs.
• Make-versus-buy decisions with off-highway/agricultural suppliers.
• Durability considerations: heat, vibration, dust, long shift work.

Responsibilities

• Own platform-level mechanical systems end to end from concept to field release.
• Lead detail design, release drawings, tolerance stacks, and GD&T with vendors and shops.
• Set and execute test programs, learn from field failures, and improve designs.

Description

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

Summary

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.
