Senior Fullstack Engineer

Role Overview

• The Senior Full Stack Engineer leads the technical design and delivery within a single squad and line-manages 1–2 Full Stack Engineers.
• Ensure the squad delivers secure, reliable, and accessible products, while maintaining high engineering standards and an excellent developer experience.
• Use expertise in Spring Boot microservices (Kotlin/Java) and modern web technologies (React/TypeScript) to design and deliver complex features end-to-end.
• Drive best practices in observability, CI/CD, security, performance, and accessibility.
• Create and maintain Architecture Decision Records (ADRs) for significant decisions, aligning with organization-wide patterns.
• Provide technical mentorship and line management for Full Stack Engineers in the squad, supporting their growth in technical skills, ownership, and delivery capability.
• Collaborate closely with Product Managers and Designers to ensure technical feasibility, shape solutions, and align technical work with product goals and timelines.

Requirements

• Strong experience designing, building, and operating Spring Boot microservices in Kotlin or Java, including REST APIs, integrations, and containerised deployments on a major cloud platform (Azure preferred; AWS or Google Cloud also relevant).
• Good knowledge of React and TypeScript, with practical experience building accessible, performant, and maintainable user interfaces.
• Proven ability to design robust, scalable solutions within a squad context, aligning with broader architectural guidelines.
• Good understanding of distributed systems fundamentals (resilience, latency, consistency, failure modes) appropriate to microservices.
• Strong understanding of secure coding practices (e.g. OWASP), privacy considerations, and security/compliance expectations in production systems.
• Experience with observability tooling, incident response, and CI/CD pipelines; familiarity with Azure DevOps Pipelines and Azure deployment services is beneficial.
• Demonstrated ability to improve codebase quality through refactoring, better abstractions, and clear boundaries between modules and services.
• Experience mentoring engineers (pairing, code review, design guidance) and some experience of line management or formal coaching responsibilities.
• Experience using GenAI tools (such as GitHub Copilot) to improve productivity and code quality, with a clear understanding of their limitations and validation requirements.
• Strong communication and collaboration skills, able to work effectively with Product, Design, and other stakeholders to deliver outcomes.
