About the Role
We are looking for a Senior Full Stack Developer to join a CommIT team delivering mission-critical systems for a leading financial institution. You will own features end-to-end across the full stack, working in a secure, highly regulated banking environment where reliability, code quality, and disciplined process matter as much as speed.
This is a hands-on senior role on a layered enterprise architecture. You will be expected to operate confidently across all tiers — from the React client through to the core banking integration — and to raise the engineering bar for the team. We build with modern, AI-assisted workflows, so developers who are fluent with tools like Cursor and Claude Code will feel at home.
Key Responsibilities
- Design, build, and maintain full-stack features end-to-end across the client, BFF, and middleware tiers.
- Develop responsive, accessible UIs in React and build the Backend-for-Frontend layer in Next.js / JavaScript.
- Implement and integrate middleware services in .NET / C#, connecting to core banking systems and third-party financial APIs.
- Write secure, well-tested, maintainable code, with unit and integration test coverage as part of the definition of done.
- Work within the bank's SDLC and governance — change management, environment promotion, security and compliance gates, code review, and release control.
- Participate in design discussions and code reviews; mentor team members and improve engineering practices.
- Collaborate with product, QA, architects, and the client's teams in a delivery-focused, client-facing setting.
Must-Have Qualifications
- 5+ years of professional full-stack development experience.
- Front-end: strong React, including modern patterns, state management, and component architecture.
- BFF / JavaScript: hands-on experience building Backend-for-Frontend layers with Next.js (Node / JavaScript / TypeScript).
- Middleware: solid .NET / C# development, building services and integrations.
- Layered architecture: proven experience designing and developing across a Client → BFF → Middleware → Core structure, with a clear grasp of each tier's responsibilities and boundaries.
- Regulated SDLC: experience working within a bank's (or comparable regulated enterprise's) software development lifecycle — formal change management, security and compliance gates, and release governance.
