At Halter, we know how much farmers care-for their animals and their pasture. But the tools they rely on haven’t kept up, and we’re on a mission to change that. Halter helps farmers make smarter decisions - fast. We reckon good pasture management is the key to more productive and sustainable farms. More grass. Healthier soil. Happier animals. And more time back for the people doing the work. ABOUT THE ROLE We’re looking for an epic React Native engineer with a product-obsessed mindset and the ability to lead-someone who cares about what we build, and why. This is a rare chance to solve hard mobile problems at scale. As a lead, you’ll be across our iOS and Android app experience end-to-end-TypeScript, React Native, and the native bridges that make it work. You’ll be hands-on and collaborative; shipping features, improving performance, hardening offline behaviour, and shaping how we work. We care about how you think and act: curious, thoughtful, practical, and someone who takes absolute ownership. WHAT YOU’LL DO - Lead the architecture and implementation of core React Native features, including native modules/bridges where it makes sense. - Bring a strong product lens - you’ll work closely with design and product to make smart trade-offs and ship high-impact features fast. - Use AI tools (e.g. Claude, Cursor) to boost quality and speed without sacrificing readability or tests. - Drive app performance from every angle - The Halter app has a complex mobile product, understanding of how to tune it is an essential skillset. - Build resilient offline-first flows and graceful error handling for real-world field conditions. - Evolve our mobile design system and UI patterns.Raise the bar through reviews, pairing, and mentoring. YOU’LL BE GREAT IF YOU - Are deep in React Native and have strong opinions on mobile architecture (navigation, state, module boundaries). - Think like a product engineer-customer outcomes first, clean code in service of that.Know when to go native and how to design stable bridges. - Have shipped complex React Native apps in cross-functional teams. - Thrive in fast-moving, ambiguous environments.Understand performance deeply, accessibility, testing, and maintainability. - Bonus: experience wit
