Fullstack Engineer, Growth

- Development style

- Small team (Growth Team), short path from idea to production

- You work directly with designers, PMs, and analysts, without a ticket queue in between

- Decisions get settled by shipping and measuring rather than by debate

- A senior growth engineer on the team to review your work and learn from

- Team communication is in English

- On-site / Remote hybrid.

Responsibilities

- Build and own features across the stack, from database and API through to the interface users touch

- Design and implement the API endpoints new product surfaces depend on

- Implement frontend work coming from design, from small UI corrections through to full components and flows

- Ship experiments and instrumentation on activation, conversion, and engagement flows, and iterate on what the data says

- Work on generative AI product surfaces: prompt flows, generation pipelines, the places where model behavior meets UX

Tech stack

- Frontend: React + TypeScript, Tailwind CSS

- Backend: Node.js + TypeScript, GraphQL, RPC, PostgreSQL

- Infrastructure: AWS, Docker

- Experimentation / Analytics: Amplitude, Snowflake

Requirements

- 3–5+ years building and maintaining products used by real users

- Shipped both frontend features and backend services or APIs in production

- Able to design and implement well-structured API endpoints

- Strong enough on the frontend to implement a design faithfully and catch quality issues before users do

- Comfortable clarifying underspecified work yourself instead of waiting for a spec

- Honest estimation, and early flagging when something is blocked or bigger than it looked

- Basic SQL, enough to check that what you shipped did what you expected

- Professional experience with B2C / consumer-facing products

- English at business level
