​
Senior Full-Stack Web Developer

• Dublin – Hybrid

• Long term contract

• Daily Rate Negotiable

Semi state body within Aviation is looking to hire a Senior Full-Stack Web Developer. This role will be pivotal in designing, building, and maintaining end-to-end web applications that power a digital ecosystem — from user-facing interfaces through to server-side architecture and integration layers.

Key Responsibilities

• Develop and maintain scalable, high-performance web applications using React and Next.js.

• Design, develop, and maintain server-side applications and microservices using Node.js.

• Architect and manage secure, high-performance APIs (REST or GraphQL) for web and mobile consumption.

• Collaborate with UI/UX designers to translate wireframes and visual designs into high-quality, responsive code.

• Optimize applications for maximum speed, scalability, and SEO, leveraging Next.js features (SSR/SSG).

• Integrate applications with headless CMS platforms, third-party suppliers, legacy systems, and internal data sources.

• Design and maintain database schemas (SQL or NoSQL) to support data-driven applications.

• Advocate for front-end best practices, including accessibility (WCAG), modular component design, and state management.

• Perform root cause analysis of technical issues and ensure the stability and security of the production environment.

• Collaborate with Enterprise Architects to ensure alignment with data governance, security protocols, and cloud infrastructure standards.

• Participate in sprint planning, backlog refinement, and technical grooming — providing effort estimations, feasibility insights, and technical leadership across the stack.

• Work closely with QA teams to ensure features are thoroughly tested and meet acceptance criteria.

• Support the Programme Manager by identifying technical risks and dependencies, and providing transparency on technical progress.

Knowledge, Skills and Experience

• A minimum of 5 years' experience as a Full-Stack or multi-stack Developer working on large-scale, production-grade web applications in complex technical environments.

• Expert proficiency in JavaScript (ES6+) and TypeScript across both client and server.

• Strong expertise in React and Next.js for front-end development, and Node.js for server-side development.

• Strong understanding of modern CSS methodologies (e.g., Tailwind, CSS Modules, or Styled Components).

• Experience with state management libraries (e.g., Redux, Context API, or Zustand) and data fetching (React Query/SWR).

• Deep understanding of database management (e.g., MSSQL, PostgreSQL, MongoDB) and caching strategies (e.g., Redis).

• Experience with cloud platforms (Azure preferred) and CI/CD pipelines for automated deployment.

• Proficiency in other relevant languages (e.g., Python, Go) or frameworks is an advantage.

• Proven ability to identify and implement technical solutions that meet business needs and represent value for money.

• Highly organized and detail-oriented, with a focus on writing clean, maintainable, and well-tested code.

• Strong interpersonal and communication skills, enabling collaboration within a cross-functional squad and translating complex technical concepts for stakeholders.

• Self-driven and accountable, with a strong sense of ownership over end-to-end application architecture.

• Deep experience with Agile delivery models and tools such as Jira or Azure DevOps.
