TypeScript Engineer
£500- £550 per day Outside IR35
1 day onsite - London
We're working with a large international travel and transport organisation that is modernising its digital ecosystem following the consolidation of multiple business units. The company is investing heavily in next-generation data and middleware platforms, and they're looking for a TypeScript Engineer to help shape the services and tooling behind this transformation.
The team's mission is to replace legacy systems with clean, event-driven services and provide consistent, reliable data to applications across the business - from customer-facing products to operational systems.
The Role
You'll be joining a multidisciplinary engineering team focused on building backend and occasionally frontend components using modern TypeScript across Node.js and React/Next.js. The role centres on developing APIs, event-driven services, and internal tools that support large-scale, cloud-hosted workloads.
You'll work closely with engineers, analysts, and product specialists to design scalable services, contribute to architectural improvements, and help evolve the company's approach to distributed data and developer experience.
Day-to-day responsibilities include:
Designing and implementing backend services in TypeScript using Node.js (REST, GraphQL, workers, event-driven consumers).
Building and integrating services that interact with event-sourced or streaming systems.
Creating clean, well-structured APIs and internal tools to improve data distribution across the organisation.
Writing high-quality, well-tested code using modern testing frameworks and patterns.
Occasionally contributing to simple React/Next.js based UI screens for configuration or internal tools.
Improving system reliability, observability, and developer efficiency through metrics, logging, and automation.
Working closely with cross-functional teams in an agile environment, contributing to planning, delivery, and code reviews.
Supporting continuous improvement of codebases, development workflows, and shared engineering standards.
