Job Description
Senior Fullstack Engineer, ReactJS/Node.js
Playbook
• Design and implement new features across the stack (Node.js and ReactJS), with a strong focus on usability, clarity, and real user value, shaping APIs and GraphQL contracts as part of the feature design process. • 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. • Ability to break down product requirements into data models, GraphQL types, and frontend component structure before writing implementation code.
Job Requirements
- 5+ years of professional software development experience, with a strong focus on full-stack JavaScript / TypeScript. Proven experience shipping production web applications end-to-end.
- Strong experience with React.js and modern frontend patterns. Ability to build responsive, user-friendly interfaces with attention to detail and performance. Familiarity with TailwindCSS or similar styling frameworks.
- Strong experience with Node.js, including designing GraphQL schemas and understanding resolvers, dataloaders, and API structure for maintainability.
- Advanced TypeScript proficiency. Our codebase is heavily typed — you should be comfortable writing complex types, generics, conditional types, and using TypeScript to enforce contracts and model domain logic across the stack.
- 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 experience working with relational databases (PostgreSQL preferred), including schema design, query optimization, and reasoning about data consistency and performance.
- Strong communication skills in English. Comfortable working in a remote, cross-timezone team and collaborating asynchronously.
Benefits
- Equity options
- 100% remote with flexible working hours and async-friendly culture. Collaboration across Europe and the US East Coast.
- A collaborative team that values ownership, open communication, and autonomy over micromanagement.
- Yearly team retreats focused on connection, alignment, and building strong team relationships.
- Paid Time Off
