Job description

The work

Full-Stack Developers deliver coherent features across the browser, service, and data layers. They can follow a user need through a React interface, an API, back-end logic, and a database change, then make sure those parts work together as one understandable system.

The role is defined by integration and end-to-end ownership, not by claiming equal depth in every specialty. You decide where logic belongs, keep contracts aligned, test the seams between layers, and work with deeper specialists when architecture, database operations, security, accessibility, or platform concerns exceed the feature team's scope.

You might spend one day improving a component and its state, another changing an API and schema migration, and another tracing a production failure across several services. Strong full-stack work reduces handoff gaps while preserving clear boundaries, review, and operational accountability.

What you'll build

• End-to-end features spanning React interfaces, back-end services, APIs, and relational data.
• Typed client and service contracts, validation rules, authentication flows, and authorization checks.
• Schema migrations, queries, service logic, component state, and accessible user interactions.
• Automated tests across unit, component, integration, contract, and browser layers.
• Delivery automation, diagnostic logging, metrics, traces, and runbooks for owned features.

Who you are

You are comfortable crossing layer boundaries while staying honest about risk and depth. You can diagnose whether a problem starts in the browser, the network contract, service logic, a query, or deployment configuration, and you bring in a specialist when the evidence points beyond your ownership.

You care about the complete user outcome. You keep interfaces and data contracts explicit, avoid hiding complexity in the wrong layer, and communicate changes so front-end, back-end, data, security, quality, and operations partners can review them effectively.

What you bring

• Hands-on experience with React and TypeScript or JavaScript plus at least one modern back-end language and framework.
• Ability to design and integrate HTTP APIs, application logic, relational schemas, SQL, and browser state.
• Understanding of authentication, authorization, validation, transactions, accessibility, secure coding, and error handling.
• Experience with automated tests, version control, code review, delivery pipelines, and production diagnostics.
• Judgment about layer boundaries, service contracts, migration safety, maintainability, and when specialist review is required.
