Senior Fullstack Developer

About this role This role is for a Senior Full-Stack Developer, front-end leaning, who will report directly to the Technical Director.

You'll spend the majority of your time designing and building high-performance, scalable user interfaces, while also owning the API and data layer that powers them — working end-to-end on modern, full-stack applications. What will this role do?

Lead the architecture, design, and development of complex applications using React, Next. js, and TypeScript, along with the Node. js-based APIs and services that support them. Design and build RESTful and/or GraphQL APIs, including data modeling, authentication, and integration with SQL/NoSQL databases.

Collaborate closely with clients, product managers, UI/UX designers, and back-end engineers to translate business requirements and design mockups into functional, full-stack solutions.

Act as a technical expert across the stack, providing guidance to junior and mid-level engineers on both front-end and back-end best practices. Drive adoption of modern development techniques, tools, and frameworks — front-end and back-end alike.

Ensure the performance, scalability, security, and maintainability of applications from the UI down through the API and data layer. Leverage Next. js server-side capabilities (SSR, RSC, API routes) to blur the line between front-end and back-end where it improves performance or developer experience.

Participate in code reviews across the stack, ensuring code quality, consistency, and adherence to established standards. Troubleshoot and debug complex issues spanning the client, API, and data layers.

Effectively communicate technical concepts and project progress to both technical and non-technical stakeholders, including clients. Stay up-to-date with emerging front-end and back-end technologies and trends, evaluating and recommending new approaches where appropriate.

Contribute to project planning, estimation, and technical documentation across the full stack. What do you n
