Software Engineer

About the role

You will primarily work on our Expo/React Native app for iOS and Android. Working closely with the CTO means that your code reviewer, collaborator and the person you push back on about engineering decisions are the same person for now, giving you direct mentorship from the CTO day-to-day.

Responsibilities

• Design, build, and maintain features within our Expo/React Native mobile application.
• Deliver polished, performant experiences across iOS and Android using Expo's managed and bare workflows.
• Write and maintain tests alongside feature development, taking joint ownership of the codebase's quality.
• Review the CTO's code, and have yours reviewed in return.
• Contribute to product decisions; we don’t have a wall between engineering and product.
• Contribute to architectural discussions and help uphold engineering standards across the codebase.

Requirements

• Professional experience with React Native and/or Expo, with experience shipping apps on the App Store and Google Play Store.
• Strong proficiency in TypeScript and modern React patterns (hooks, context, component composition).
• Solid understanding of mobile-specific concerns: performance, offline handling, device APIs, and platform differences.
• Familiarity with CI/CD pipelines for mobile (EAS Build or equivalent).
• Clear written and verbal communication.
• Any backend experience (Laravel/PHP is our current stack, but any MVC framework translates). We’ll teach you the rest.
• Experience with analytics tools such as Amplitude or similar event-tracking platforms.
• Experience with observability and associated tools such as Sentry, Grafana, Prometheus, Datadog etc.
• Interest in growing into full-stack engineering responsibilities.
• Strong opinions about using AI tools in the development loop — we use Claude Code and Codex heavily, and are interested in various other similar tools, and we’re interested in how you’d push that further.

This role is a growth role within a small but fast-growing organisation. While it immediately begins as a primary contributor to our React Native application, we expect and encourage growth into full-stack engineering over time. As you become familiar with our codebase, product and systems, you will have the opportunity to take on work across our Laravel API, with ample growth opportunity and coaching to become a full-stack contributor. Looking further ahead, we are planning to migrate our backend from Laravel/PHP to TypeScript over the next 12-18 months, bringing the entire stack into a single language. Should this be appealing to you, there’s a genuine role in helping shape that transition.
