About the role

Key responsibilities & impact

Design and implement new features across the stack (Node.js, ReactJS, and React Native), with a strong focus on usability, clarity, and real user value, shaping APIs and GraphQL contracts as part of the feature design process.
Spend the majority of your time in your area of deep expertise, while regularly contributing across the web app, the backend, and the mobile app — picking up features, smaller tasks, and code reviews wherever they're needed.
Build and evolve backend services and APIs (REST and GraphQL) that power our platform. Focus on reliability, maintainability, and clean integrations with frontend applications and third-party services.
Work closely with Product Managers and Designers to translate requirements into practical, well-scoped technical solutions.
Contribute to Engineering Requirement Documents (ERDs) that define data models, API contracts, and integration points before implementation begins.
Write clean, readable, and well-tested code. Participate in code reviews and contribute to shared standards around quality, testing, and maintainability. Improve existing systems where it provides clear product or developer value.
Take responsibility for the features you build. Identify issues or gaps, propose improvements, and iterate based on feedback. You're comfortable working with some ambiguity and adapting as requirements evolve.
Break down product requirements into data models, GraphQL types, and component structure before writing implementation code.

Requirements

What you’ll need

5+ years of professional software development experience with TypeScript as your primary language. Advanced TS proficiency — complex types, generics, conditional types, and using the type system to enforce contracts and model domain logic across the stack.
Proven experience shipping production applications end-to-end and owning features from design through release.
Active daily use of AI coding assistants (Claude Code, Codex, OpenCode, or similar) for development, debugging, and problem-solving. We expect engineers to leverage these tools to ship faster and work through complex problems.
Strong communication skills in English. Comfortable working in a remote, cross-timezone team and collaborating asynchronously.
Deep senior expertise in at least ONE of:
- Web (ReactJS): modern frontend patterns, performance, component architecture, responsive and user-friendly interfaces with attention to detail. Familiarity with TailwindCSS or similar styling frameworks.
- Backend (Node.js): GraphQL schema design, resolvers, dataloaders, and API structure for maintainability. Strong experience with relational databases (PostgreSQL preferred), including schema design, query optimization, and reasoning about data consistency and performance.
- Mobile (React Native): shipping and maintaining production RN apps, native module integration, app store release cycles, mobile performance, and offline patterns.
Working proficiency in the other two — you can read, extend, and review code there today, and you're motivated to grow toward senior level across all three. If you've only ever worked in one lane and want to stay there, this role isn't a fit.
