Brumby · Sydney ·
Senior Embedded Systems Engineer at Brumby, a YC-backed startup building autonomous drones that herd and monitor cattle on large ranches. You own electronics and firmware across aircraft and docks — designing PCBs, tuning ArduPilot, and integrating Jetson onboard compute — working on-site in Sydney with field deployments to cattle stations.
Founded in 2025 by Sam Rogers, who grew up managing 6,000 head on a North Queensland cattle station, Brumby builds autonomous drones that move and monitor cattle across the world’s largest properties. We’re replacing helicopters and motorbikes with drones that herd cattle, count herds, and monitor pasture on their own. Helicopter mustering is expensive, dangerous, and still misses cattle. Our drones launch from a dock, fly the paddock, do the work, and come home.
We went through YC (W26) and raised a seed round from the best investors in the valley. Our team is small and highly technical, and we’re already working with some of the largest ranches in the world. Engineering is based in Sydney, but the work happens everywhere. Expect to write code at a desk, in a truck, and in the dirt. We work hard because our ranchers do.
We have a team of 6 which is growing steadily, including Computer Vision, Robotics, AI Engineers and a Chief of Staff. We are looking to add an Embedded Systems Engineer who will own the electronics and firmware across our aircraft and docks. This is a hands-on role with full ownership of the hardware domain, and you’ll set the bar for how we design, build, and test everything that flies.
You will own the hardware that keeps Brumby’s drones in the air and brings them home. Every board on the aircraft and every circuit in the dock will pass through your hands, and you will take them from first power-up on the bench to a working system on a cattle station hundreds of kilometres from the nearest town.
On the aircraft, you will design and bring up the motherboard and battery pack board, integrate the flight controller and Jetson, and tune ArduPilot. On the ground, you will build the electronics and firmware that let the dock launch, recover, and charge aircraft daily.
You’ve taken avionics from design through to flight, owning power, sensors, and flight controller integration
Deep experience with ArduPilot and getting real aircraft flying reliably
Strong embedded firmware experience in C/C++ on STM32
Experience integrating onboard compute with flight controllers, sensors, and aircraft systems
Experience designing and reviewing schematics and PCBs, ideally in KiCad
Comfortable debugging hardware and firmware on the bench and in the field
A track record of building reliable systems and testing them properly, not just getting them working once
A degree in electrical, electronic, or mechatronic engineering
Experience with telemetry, RF links, video systems, or gimbals
Experience with Li-ion batteries, BMS, and high-current power systems
Experience building embedded controllers for real-world machinery and safety-critical I/O
You’ve worked in a small team building quadcopters, VTOLs, RC aircraft, or similar systems
Own the avionics across our aircraft, from power and flight control through to onboard compute
Build the electronics and firmware that let our docks launch, recover, and charge aircraft autonomously
Configure and extend ArduPilot for long-range autonomous mustering
Integrate onboard compute with the aircraft so autonomy and vision systems work reliably in flight
Build hardware that keeps working through heat, dust, rain, vibration, and long periods with nobody on site to reset it
Based in our Sydney office five days a week
Regular field deployments to cattle stations (domestic and potentially international)
Full Australian working rights required
Work directly with (and report to) the founder
Competitive salary, meaningful early stage equity
Application deadline: October 30, 2026, 5PM AEDT.
