About Halter

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, no dogs, no fences. Just a group of cattle walking at their own pace. People say it looks like magic. Our customers are revolutionizing grazing with Halter. It's changing lives and transforming an industry. People join Halter to do meaningful work. By joining us you’ll be solving challenging problems within a talented team and a culture built for high performance. Our team out-think, out-work and out-care. We’re committed to delivering real change in the world - this isn’t easy, and in truth, we love that it’s hard. 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 .

About the role

Hardware at Halter is truly unique. We design and build devices that are fitted to an animal, and must remain operational 24/7 for 6-10 years out in the field. To achieve this, we iterate and improve our products continuously, so a mechanical role at Halter can be quite diverse. We own our designs right the way through, from sketching how a device might fit on an animal, to testing in the lab to see how it might break, to spending time on the production line finding ways to improve the product. We like to do things quickly, no matter which phase of the design we're in, which makes the role fast-paced and adaptive. We're endlessly challenged by our farmers, our animals, and our lofty production targets; so there's never a dull day. For the next stage, we need talented, disciplined mechanical engineers who know how to develop hardware. With plenty of new markets and revenue streams to unlock, there will be no shortage of exciting mechanical projects, all of which require problem solving, critical thinking, and the ability to execute to a high standard. These projects will offer ample opportunity for up-skilling, leadership, mentorship and career development. At Halter, our teams are small and agile, which means you get to work on the most important projects, and contribute to the company's success, whatever your role may be. 2027 will be Halter's biggest year yet, and this is your chance to be a part of it.
