Full Stack Engineer

Assignment description:

• For our client we're currently looking for a Backend / Full‑Stack Developer (React, Node.js, GraphQL).

Responsibilities:

• Migrate existing REST APIs (Next.js API routes) to a standalone Express‑based GraphQL server (Apollo).
• Design and implement a new Prisma schema based on a normalised data model; ensure the transition from Drizzle happens without data loss.
• Build GraphQL resolvers, mutations and subscriptions for schedules, visits, employees, optimisation jobs and related entities.
• Develop data mappers that translate between the new database/GraphQL layer and UI components (e.g. Bryntum SchedulerPro).
• Participate in front‑end development using React 18 + Vite: set up Apollo Client, create reusable components and migrate existing logic from Next.js.
• Handle authentication/authorisation (via Clerk) and multi‑tenant concerns
• Ensure robust test coverage, performance and code quality across back end and front end
• Contribute to technical decisions, architecture discussions and documentation.

Your profile:

• 5+ years’ experience with Node.js/TypeScript and modern web development
• Strong understanding of GraphQL and REST; hands‑on experience with Apollo Server/Client.
• Experience with Prisma or similar ORMs and relational databases (PostgreSQL).
• Familiarity with React and modular frontend architecture; knowledge of Vite and component libraries is a plus.
• Comfortable with test‑driven development and CI/CD workflows.
• Ability to work independently in a small team, communicate clearly and influence architecture and tech choices.

Nice to have:

• Exposure to scheduling/optimisation domains.
• Experience with Bryntum SchedulerPro or similar calendar components.
• Prior experience migrating between ORMs or undertaking large‑scale refactoring.

Practicalities:

Location: Hybrid or remote out of Stockholm

Scope: Full‑time or by agreement, initial project of ~20 weeks with potential extension.

Languages: Working proficiency in English (Swedish is a plus but not required).
