The opportunity
Our client is a major Dublin organisation delivering a large digital transformation programme to improve customer experience and operational efficiency through new web and mobile solutions. They are looking for a Senior Full-Stack Developer to design, build and maintain end-to-end web applications, from user-facing interfaces through to server-side architecture and integration layers.
You’ll bridge digital design and technical delivery. That means building modern front ends, creating secure and scalable APIs and services, and making sure the overall solution is resilient, well documented and delivers measurable value.
What you’ll be doing
- Building and maintaining high-performance web applications in React and Next.js, optimised for speed, scalability and SEO (SSR/SSG).
- Designing and maintaining Node.js server-side applications and microservices.
- Architecting secure, high-performance REST or GraphQL APIs for web and mobile.
- Working with UI/UX designers to turn wireframes into responsive, high-quality code.
- Integrating with headless CMS platforms, third-party suppliers, legacy systems and internal data sources.
- Designing database schemas (SQL or NoSQL) for data-driven applications.
- Championing front-end best practice: accessibility (WCAG), modular components and state management.
- Investigating root causes and keeping the production environment stable and secure.
- Working with Enterprise Architects on data governance, security and cloud standards, and with QA to meet acceptance criteria.
- Taking part in sprint planning, backlog refinement and technical grooming, giving estimates and technical leadership, and flagging risks and dependencies to the Programme Manager.
What you’ll bring
- 5+ years as a Full-Stack or multi-stack developer on large-scale, production-grade web applications.
- Expert JavaScript (ES6+) and TypeScript on both client and server.
- Strong React and Next.js on the front end, and Node.js on the back end.
- Modern CSS methodologies (Tailwind, CSS Modules or Styled Components).
- State management (Redux, Context API or Zustand) and data fetching (React Query or SWR).
- Database experience (MSSQL, PostgreSQL or MongoDB) and caching strategies such as Redis.
- Cloud experience (Azure preferred) and CI/CD pipelines for automated deployment.
- Agile delivery experience with tools such as Jira or Azure DevOps.
- Clean, maintainable, well-tested code, and strong communication across a cross-functional squad.
- Ownership of end-to-end application architecture, with a focus on value for money.
Nice to have
- Python, Go or other relevant languages and frameworks.
Working pattern
Hybrid, with three days a week on site at the client’s Dublin offices and the rest remote. Some activities, such as architecture workshops or sprint planning, may require extra on-site days, planned and agreed in advance.
