Job Description: API Developer

Our Team:
The API Developer designs, builds, and maintains the APIs that connect enterprise systems, digital products, and external partners.

The API Developer works contract-first, publishing APIs to the enterprise catalogue and developer portal, and builds the reusable components, templates, and policies that raise the standard of every API delivered across the organisation.
Kong is the primary gateway, operating alongside Apigee, Azure API Management, and AWS API Gateway across a multi-cloud estate on Microsoft Azure and Amazon Web Services. The role therefore values transferable, gateway-agnostic API skills as highly as any single product.
