Permanent | Market+ Salary + Bonus

UK Remote | Home-Based

We're looking for an experienced API Software Engineer to join a growing engineering team building and evolving a critical API platform that sits between customer-facing applications, third parties and core business systems

This is a great opportunity for a TypeScript-focused software engineer who enjoys building APIs, integrations and cloud-native services, and wants to play a key role in developing the next generation of a platform already being used by major third parties.

The platform is currently evolving towards a modern TypeScript architecture , with new endpoints and functionality being developed using TypeScript, OpenAPI standards and cloud-native technologies.

You'll join an engineering team of around 8 developers , working closely with a Delivery Lead and wider technical teams.

• Designing, developing and maintaining REST APIs used by internal and external customers.
• Building new functionality using TypeScript and modern API development practices.
• Developing new API endpoints and services as the platform continues to evolve.
• Building integrations between external applications, third-party systems and internal platforms.
• Developing APIs that allow third parties to access product and customer information, retrieve pricing and place orders.
• Working with OpenAPI / Swagger to design clear, consistent and maintainable APIs.
• Developing within a containerised, cloud-based environment , with services deployed into clusters.
• Working with AWS and technologies such as Docker, ECS/Fargate and API Gateway .
• Writing automated unit, integration and performance tests.
• Supporting CI/CD pipelines and contributing to a strong DevOps culture.
• Troubleshooting production issues and improving API performance, reliability and scalability.
• Contributing to technical and architectural decisions as the TypeScript platform develops.
• Producing clear technical documentation and sharing knowledge across the team.

The technology

The newer generation of the API platform is being built using TypeScript , with the team continuing to expand this architecture and introduce new functionality.

You'll ideally have experience with some of the following:

• TypeScript
• RESTful APIs
• JSON
• AWS
• Docker / containerisation
• ECS / Fargate
• API Gateway
• CI/CD
• Automated testing

Experience working with an existing enterprise API platform or integrating with internal and third-party systems would also be highly beneficial.

There is an existing Java-based platform within the wider estate, so exposure to Java would be useful, but TypeScript and API development are the key areas of focus for this role .

We're particularly interested in engineers who:

• Have professional experience building APIs using TypeScript / Node.js .
• Have a strong understanding of REST API design and OpenAPI standards .
• Have experience building integrations between systems and services.
• Understand cloud-based and containerised application environments.
• Are comfortable working with AWS and modern development practices.
• Can work within an existing platform while also helping shape its future architecture.
• Take ownership of their work and care about building well-engineered, maintainable software.
• Can communicate technical concepts clearly and work effectively with both technical and non-technical stakeholders.
