Jora New Zealand will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey.

We're looking for an epic Senior/Lead Mobile Engineer with deep expertise in iOS native development and a product-obsessed mindset. This role requires a strong appetite for delivering a truly native mobile experience through a React Native codebase. As a leader, you will drive an obsession with creating fast and beautiful user experiences, alongside a deep focus on performance and improving the developer experience across the board. You'll be hands-on and collaborative, refining our ability to deliver a top-tier native mobile experience as we grow. Collaborating with our product and platform teams this engineer will be responsible for guiding our incredible mobile app into the place it needs to be. 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 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 a seamless and performant native mobile application.
• Bring a strong product lens-work 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 optimizations 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.
• Evolve our mobile design system and UI patterns. Raise the bar through reviews, pairing, and mentoring.

You’ll Thrive In This Role If You

• 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 optimization 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.

Our Office First Approach

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.
