About the Role
We are seeking a front-end leaning full-stack engineer to build features end-to-end on our Next.js and tRPC stack. This is a greenfield product where you will collaborate directly with founders and our design engineer to shape product architecture. A key responsibility is ensuring the application is beautiful and fully responsive across all devices.
Responsibilities
- Build new features end-to-end across the frontend (Next.js 15, React Server Components) and the tRPC API layer
- Own making the app fully responsive across mobile, tablet, and desktop
- Work closely with our design engineer in London to craft beautiful, functional UI using shadcn/ui and Tailwind CSS
- Design and build backend functionality: tRPC procedures, data models, and integrations with PostgreSQL
- Ensure strong accessibility (WCAG) and quality across browsers
- Contribute tests (Vitest + Playwright) and take part in code review
Requirements
- 3+ years of full-stack experience building B2B SaaS products, shipping features end-to-end
- Proficiency in React, TypeScript, and the Next.js App Router
- Experience with tRPC (or similar API layers) and PostgreSQL
- Strong responsive/mobile-first design skills with Tailwind CSS
- Experience with shadcn/ui, Figma, or design-system collaboration
- Testing experience with Vitest, Playwright, or equivalents
- Ability to work autonomously in a fast-paced, early-stage environment without detailed specs
- A true full-stack, growth mindset — not narrowly specialized in only frontend or only backend
- Based in or willing to relocate to SF
- Willingness to travel to the UK or Norway roughly once a month
- Candidates must have existing work authorization in the US (or UK/EU for our other offices)
