Contract Senior Full Stack Engineer

Who we are:

AND Digital are a tech company focused on accelerating digital delivery and dedicated to closing the digital skills gap. We’ve been helping organisations build better digital products and stronger digital teams since 2014.

We believe our work should always make a remarkable impact for our clients. We do this through our regional offices (or ‘Clubs’) building strong relationships with our partners, so that they are always prioritised by a team within close proximity. 

This unique model has driven success for our clients and ourselves, evidenced by our remarkable organic growth since 2014. Today we number more than 1,300 people with Clubs all over the UK, Europe and the USA with plans for global expansion in the next couple of years.

About the Role:

• Design, document, and evolve architecture, ensuring modularity, scalability, resilience, and extensibility across micro-frontends and microservices.
• Lead end-to-end system design, including API gateways, service orchestration, integration patterns (e.g., module federation, event-driven architecture), and distributed systems.
• Demonstrate deep expertise in React (including advanced patterns, SSR/SSG, Next.js), Node.js, TypeScript, and Azure cloud services.
• Define and enforce comprehensive testing strategies (unit, integration, E2E) using Jest, Testing Library, Playwright, and champion TDD/BDD practices.
• Architect and implement scalable, secure APIs (REST, GraphQL), event-driven services (Kafka), and robust error handling.
• Advanced SQL (PostgreSQL), schema design, query optimisation, and NoSQL where appropriate; lead data modelling and migration strategies.
• Demonstrate expert knowledge and application of the OWASP Top 10 security risks; proactively identify, remediate, and educate the team on security vulnerabilities.
• Architect logging, monitoring, and tracing strategies (OpenTelemetry, Prometheus, Application Insights), and drive adoption of best practices for platform reliability.
• Architect and optimise CI/CD pipelines (Azure DevOps, GitHub Actions), automate quality gates, enable blue/green deployments, and drive continuous delivery.
• Set and enforce standards for Terraform/ARM templates, environment management, and disaster recovery; ensure infrastructure is robust, repeatable, and secure.
