Additional Information

About Allica Bank Allica is the UK's fastest growing company - and the fastest-growing financial technology (Fintech) firm ever. Our purpose is to help established SMEs, one of the last major underserved opportunities in Fintech. Established SMEs are the backbone of local communities - representing over a third of our economy - yet have been largely neglected both by traditional high street banks and modern fintech providers. Technology sits at the centre of Allica. We design and build the platforms that power the bank, working closely with every part of the business to deliver real impact for customers. Our teams move quickly, focus on outcomes, and take ownership from concept through to delivery. We solve complex problems, modernise processes, and enable the business to scale with confidence. What makes us different is the level of influence and autonomy engineers have. We work without the weight of legacy systems, which means we can focus on building for the future. Everyone contributes ideas and helps shape how we operate, and roles evolve as the organisation grows. This is a place for people who want to have a tangible impact and do their best work in a modern, collaborative environment. Role Description The Full Stack Engineer contributes to the design and delivery of products within a squad, helping to build secure, reliable, and accessible software while maintaining high engineering standards and a good developer experience. You will use your skills in Spring Boot microservices (Kotlin/Java) and modern web technologies (React/TypeScript) to deliver features across the stack. Our backend services run as containerised applications on Azure Container Apps, and our web applications are deployed via Azure Static Web Apps; you will help ensure the services and applications you work on are production-ready and make effective use of these platforms. You will contribute to good engineering practices in observability, CI/CD, security, performance, and accessibility, helping systems meet the standards expected of a UK bank. You will contribute to Architecture Decision Records (ADRs) and follow organisation-wide patterns and standards. You are hands-on and collaborative: you help design features, write code, review changes, and work closely with engineers, Product, and Design to deliver valuable outcomes. You use approved GenAItools such as GitHub Copilot, Codex or Claude Code responsibly to improve productivity and quality, while validating outputs carefully. Success in this role is measured by the consistent delivery of high-quality features, contribution to reliable and maintainable systems, improvements to the codebase and operational health of services, and your growth in technical capability and ownership. Principal Accountabilities: Contribute to the end-to-end design and delivery of features across the full stack using: Backend: Kotlin/Java Spring Boot microservices, containerised and deployed on Azure Container Apps, exposing REST/OpenAPI APIs and integrating with other services and data stores. Frontend: React/TypeScript, shared design system components, and agreed architectural patterns, deployed on Azure Static Web Apps. Contribute to technical design discussions and help produce clear ADRs for significant decisions, documenting context, options, trade-offs, and outcomes in line with organisation standards. Support the squad's services in production by contributing to SLOs and operational metrics, monitoring systems, responding to incidents, and helping to reduce recurring issues and improve reliability. Apply secure and compliant engineering practices: Follow secure coding standards and contribute to threat modelling activities. Ensure logging, audit trails, and data handling meet regulatory and privacy requirements. Ensure accessibility standards are met in user-facing features. Help strengthen observability and operational excellence within the squad by contributing to metrics, tracing, logs, dashboards, runbooks, and alerts, and using them effectively in day-to-day engineering work. Contribute to improvements in developer experience, including CI/CD pipelines, test strategy, local development workflows, and release practices, in line with wider engineering standards and cloud deployment patterns. Use AI-assisted engineering responsibly: Use approved tools like GitHub Copilot, Codex or Claude Code to improve speed, quality, and consistency. Validate and refine AI-generated code to ensure correctness, maintainability, and compliance. Share feedback and effective practices with the team. Collaborate closely with Product Managers and Designers to understand requirements, shape practical solutions, and deliver work aligned to product goals and timelines. Maintain high standards of code quality, testing, documentation, and maintainability across the squad's codebase, while helping to reduce technical debt. Support other engineers through pairing, code review, and knowledge sharing, cont
