Senior Developer — Mobile (React Native)

Build mobile apps people rely on every day — with shared ownership and real support.

At Spark, Senior Tech Developers are hands‑on engineers who also lead people and practice. You’ll stay close to the code while helping shape how mobile engineering evolves over time.

We’re looking for a React Native Senior Developer to co‑lead our mobile app space — working across the Spark and Skinny apps and partnering closely with another experienced mobile lead.

🌱 Why this role is different

• Leadership is shared, not isolated
• Quality, accessibility and sustainability are valued as much as speed
• You’ll have space to influence how mobile work gets done — not just what gets built

This role suits someone who enjoys craft, collaboration and thoughtful leadership.

🔍 What you’ll be doing

• Help lead development using React Native, TypeScript and Expo
• Help guide app performance, stability and release quality
• Shape mobile engineering standards — testing, accessibility, design systems
• Support and mentor mobile engineers through reviews and pairing
• Partner with product, design, web and platform teams to deliver end‑to‑end outcomes
• Use AI tools as accelerators, with judgement and care

🧠 What you’ll bring

You might recognise yourself in many (but not all) of these:

• Experience building and shipping React Native apps in production
• Strong TypeScript skills and interest in mobile best practice
• Working knowledge of iOS and Android environments
• Comfort taking responsibility for app quality without being “on your own”
• A leadership style that’s inclusive, calm and considered

✨ Why Spark

• Apps used by millions of New Zealanders
• Peer leadership and shared accountability
• Flexible working, wellbeing support and career development
• A culture that values diverse perspectives and approaches to leadership
