About the role

Key responsibilities & impact

Build and improve features across the web (React/TypeScript) and mobile (React Native/Expo) applications — constantly raising the bar on what "good" looks like for our customers.
Own features end-to-end — collaborate with product and design, design and implement APIs, write the code, write the tests, ship it, monitor it.
Drive meaningful improvements to stability, performance, and UX — identifying and eliminating pain points proactively, not just reactively.
Design and build APIs in NestJS/TypeScript that power rich, responsive experiences across web and mobile.
Leverage AI tools to move faster and write better code — you treat AI assistants as a core part of your workflow for coding, debugging, code review, and research.
Raise the bar on code quality through thoughtful code reviews, targeted refactoring, and knowledge sharing.
Triage and resolve bugs with urgency and care, minimizing customer impact.
Contribute to technical decisions on architecture, tooling, and patterns within the applications team.
Mentor and support teammates — share what you know and lift the team.

Requirements

What you’ll need

Strong production TypeScript and React experience — ideally with long tenure on a single mature product, not just a series of greenfields.
Hands-on React Native experience — you understand the differences between web and native rendering.
Full-stack ownership: comfortable designing REST APIs (NestJS is a bonus), working with PostgreSQL and Redis, and tracing issues across the stack.
Track record on a mature, customer-facing product — you know how to improve something trusted by thousands of customers without breaking it.
You take pride in the work — clean code, good tests, thoughtful naming, and UX that feels right matter to you.
You treat improvement as a continuous obligation: refactoring with purpose, reducing tech debt, and leaving things better than you found them.
You understand that a decade-old production codebase is a feature, not a burden — complexity has history, and you have the patience and curiosity to understand it before changing it.
You actively use AI tools — Copilot, Claude, or equivalent — to accelerate your work, and you're constantly looking for more leverage from them.
Solid understanding of REST APIs and how frontend and backend systems interact — you're comfortable owning both sides.
Awareness of performance trade-offs in web and mobile contexts — you know when something will feel slow before it ships.
Ability to trace bugs across layers (UI → API → DB) and communicate clearly about root causes.
Strong opinions, held loosely — you bring perspective to technical discussions and remain open to better ideas.
Product instinct: you ask 'is this the right thing to build?' before diving into implementation, and you engage with product and design as a true partner.
Clear communicator — your PR descriptions, Jira comments, and Slack messages make sense to both engineers and non-engineers.
Comfortable with ambiguity and large surface area — you can self-direct, prioritize, and ask the right clarifying questions without hand-holding.
You move with urgency when it matters and with care when it counts.
