About the Job
At Halter, we’re on a mission to enable farmers and graziers to run the most productive and sustainable operations. Our customers are using Halter to break free from the time-intensive constraints of conventional practices. Imagine watching 500 cattle stand up and walk calmly towards their next break? No quad bikes,...
We’re backed to deliver on a mission that matters by Tier 1 investors including Founders Fund, Bessemer Venture Partners, BOND, DCVC, Blackbird, Promus Ventures, Rocket Lab’s Peter Beck and Icehouse ventures.

Required Skills & Abilities
Solid experience designing and delivering firmware for resource-constrained embedded devices, and the scars to show for it.
Strong C/C++ fundamentals and comfort working close to the hardware: interrupts, memory constraints, real-time behaviour, concurrency.
A genuine maths and/or physics background, or equivalent depth gained on the job. You should be comfortable reasoning about things like timing, signal behaviour, probability, or control systems, not just treating them as library calls.
Experience with wireless or networked communication systems (any of LoRa, BLE, cellular, mesh networking, or similar) and an interest in getting properly into the protocol details.
A strong sense of ownership. You want to understand why something works, not just that it works, and you follow problems all the way to root cause.
Comfortable working with low-level hardware and resource-constrained systems, and enjoy solving hard technical problems more than ticking boxes.
A strong team player who gives and receives feedback well.
Experience with RTOS internals (FreeRTOS or similar), and reasoning about scheduling, priorities and timing guarantees.
Experience with GPS/GNSS systems, time synchronisation, or distributed systems that need tight timing coordination across many nodes.
Background in signal processing, control theory, estimation/filtering (Kalman filters, etc.), or applied statistics.
Experience with cellular or other IoT communication technologies (LTE-M, NB-IoT, eSIM, or similar) and the quirks of getting low-power devices reliably online.
Genuine curiosity about farming, animal welfare, or hardware that has to survive outdoors, unattended, on a live animal. We can teach the domain, but the curiosity has to be there already.
