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.

We’re looking for an epic Senior or Lead Mobile Engineer with deep expertise in iOS native development and a product mindset. We’re looking for someone to help bring native performance and UX to our existing ReactNative app. You should be hands-on and collaborative, refining our ability to deliver a top-tier native mobile experience as we grow. We care about how you think and act: curious, thoughtful, practical, and someone who takes absolute ownership.
You’ll partner with an experienced Android engineer, bringing strong opinions on what a modern iOS app architecture looks like. You should have experience working in existing codebases and ideally across platforms; our mobile codebase is split across ReactNative, Kotlin, and Swift, and you’ll be spending a lot of time in each. Experience in building offline-first functionality is a strong plus. As a leader within our team, you will help set technical direction, provide product input, and improve the developer experience across the board.
Lead the architecture and implementation of core features for the Halter app, with a focus on deep native integration and components.
Collaborate closely with our React front-end engineers, guiding the domain to ensure seamless and performant interop.
Bring a strong product lens, working with Design and Product to make smart trade-offs and ship high-impact mobile features fast.
Use AI tools (e.g. Claude, Cursor) to boost quality and speed without sacrificing readability or tests.
Drive mobile app performance from every angle, focusing on metrics and optimisations to deliver a quick user experience and have minimal impact on battery life.
Build resilient flows and graceful error handling for real-world field conditions, with a focus on supporting offline-first functionality.
Evolve and build out our mobile design system and UI patterns.
Raise the bar through reviews, pairing, mentoring, and upskilling our existing React engineers.
Are deep in iOS native development and have strong opinions on mobile architecture, and systems to deliver an optimal native experience.
Experience, and scars, with App Store releases at scale, design systems, and mentoring mobile engineers.
Experience with React Native, understand how this maps to the iOS platform.
Demonstrate an obsession with performance optimisation and improving DX for mobile engineers.
Have shipped complex, high-performance native iOS applications in cross-functional teams.
Thrive in fast-moving, ambiguous environments.
Understand performance deeply, accessibility, testing, and maintainability.
A degree is a bonus, not a requirement.
Delicious snacks and drinks are available for your daily flow.
Healthy body, healthy mind. We’re partnered with Southern Cross Health Insurance to support your well-being.
We offer 6 months of fully paid parental leave for primary caregivers, 4 weeks of fully paid secondary caregiver leave and many other parental benefits that support you and your family.
Our personal growth is important. Halter offers an annual $1000 self-development budget to be used for anything that fuels personal growth.
Our time to recharge is valued, we’re offered wellness leave and unlimited paid annual leave.
Importantly, we offer an inclusive and attractive remuneration package made up of salary, benefits and an employee stock ownership plan.
There’s a reason you visit your friends in person, live with your family and don’t do dinners over Zoom. Humans are wired for connection. We believe a world-class, in-person office culture is the best way for high-performing teams.
Being office first is a core pillar of our culture. We believe in-person connections are key to driving your own growth, learning, impact, and building genuine long-lasting relationships. Strong relationships make it easier to disagree, give feedback, and do meaningful and aligned work. We don’t like having heaps of rules or policies, but this means having strong, trusted relationships is critical.
We’re office first, not office only. This means working from the office everyday is our default setting, but we flex when we need to. We have a high-trust culture, so everyone is trusted to do what’s best for Halter.
Our office vibe is something special, it’s hard to describe until you’re here, but people at Halter who have come from fully remote or hybrid companies say they could never go back - the high energy and spectacular people they are now surrounded by everyday makes work so enjoyable. Your growth, your learning and your impact is truly unlimited here, and a big part of that comes from being together solving problems, innovating, building context, and constantly learning from each other.
Halter is committed to promoting a diverse and inclusive workplace — a place where we can each be ourselves and do the best work of our lives. Research shows that while men apply to jobs when they meet an average of 60% of the requirements, women and under-represented groups of candidates tend to only apply when they meet every requirement. If you think you have what it takes but don’t necessarily tick every requirement on this job description, please still get in touch and apply to Halter. We’d love to chat to see if you’ll be an epic fit!
