Job summary

Solvd is seeking a Senior Full Stack Engineer to join a fast-paced product team building a leading platform. You’ll own features end to end—from API design to UI—working across a modern TypeScript stack with GraphQL, React, and strong backend/data focus.

You’ll collaborate in a two-week sprint cadence and contribute to testing strategies. The role emphasizes end-to-end ownership, hands-on React/TypeScript delivery, API design with Apollo Server, and modern tooling (Docker, ORMs, caching).

• Fluency in TypeScript — frontend and backend.
• Hands-on experience with React in a production environment.
• Experience building and modifying GraphQL APIs using Apollo Server.
• Experience working with Docker for local development and service packaging.
• Familiarity with ORMs — Prisma, TypeORM, Objection.js, or similar — and query builders; experience with Knex is a plus.
• Experience using Redis and common caching patterns.
• Comfortable working across the full stack —frontend, backend, and data layers.

Responsibilities

• Own features end to end, from design through to implementation and release.
• Design, implement, and modify GraphQL APIs — schemas, queries, mutations, and resolvers — using Apollo Server.
• Design and evolve backend services, including data access and caching layers.
• Modify and extend database schemas as needed using ORMs and query builders.
• Build user interfaces using React and TypeScript.
• Write and maintain unit tests.
• Modify and add end-to-end tests using Cypress.
