This is a hands-on engineering role responsible for producing well-designed, robust, scalable, secure, well-documented APIs that other teams can discover and reuse for communication between internal products, third-party platforms and client-facing applications.\nThe API platform is run both as an internal product and as a managed service. 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.\nKong 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.\nMain responsibilities:\nAPI Design and Development\nDesign and build APIs contract-first using Open API/Swagger, applying enterprise design standards, naming conventions, and versioning policy. \nDevelop synchronous and asynchronous APIs across REST, GraphQL, gRPC, and event-driven patterns documented with AsyncAPI. \nBuild domain and experience APIs that expose business capabilities cleanly, abstracting the complexity of underlying systems. \nDevelop reusable API components, policies, plugins, and templates that other teams consume as a starting point. \nGateway and Runtime Implementation\nImplement and configure API proxies, routes, plugins, and policies on Kong Gateway and Kong Konnect. \nDeploy and operate gateway components on Kubernetes using the Kong Ingress Controller and GitOps workflows. \nImplement traffic management including rate limiting, throttling, caching, retries, and circuit breaking. \nSecurity and Access Control\nImplement robust authentication and authorization mechanisms (OAuth 2.0, OpenID Connect, JWT, mutual TLS, API keys patterns) \nEnsure APIs comply with regulatory and data privacy requirements (GDPR, GxP where applicable) \nIntegrate with enterprise identity providers including Entra ID and Okta. \nManage secrets and certificates through HashiCorp Vault, CyberArk, and cloud-native key services. \nQuality, Testing, and Automation\nBuild automated contract, functional, integration, security, and performance tests for every API. \nMaintain CI/CD pipelines for API delivery using GitHub Actions or Azure DevOps, including linting and specification validation. \nIntegrate static analysis, dependency scanning, and SBOM generation using SonarQube, Snyk, and equivalent tooling. \nOperations and Support\nInstrument APIs for observability using OpenTelemetry format. \nContribute during incident response, root-cause analysis, and problem management for API services. \nBuild proactive monitoring services relying on Predictive ML. \nSupport consumers through onboarding, troubleshooting, and clear technical guidance. \nTechnical Craft and Engineering Practices\nWrite clean, tested, peer-reviewed code managed in Git using trunk-based practices. \nUse AI-assisted engineering tools such as GitHub Copilot and Claude Code to accelerate development, test generation, and documentation, applying appropriate review and technical judgement. \nFavour reuse and shared components over bespoke, single-purpose implementations. \nCollaboration and Ways of Working\nWork within an agile product team with a shared backlog and defined customers. \nPartner with integration engineers, application teams, and data teams to agree interfaces and contracts. \nEngage with Cybersecurity and Architecture teams to keep API patterns aligned with approved standards. \nAbout you\nRequired\nDemonstrated capability in API or backend software engineering, typically gained across five to eight years of professional experience. \nProficiency in at least one modern backend language: Python or Node.js and TypeScript are preferred, and Java with Spring Boot is equally welcome. \nDeep understanding of REST architectural principles and GraphQL query language \nExperience with relational and NoSQL databases and the ability to write optimized queries \nStrong contract-first API design experience with Open API, including versioning and backward compatibility. \nHands-on experience with an API gateway or management platform such as Kong, Apigee, Azure API Management, or AWS API Gateway. \nPractical experience implementing OAuth2, OpenID Connect, and TLS-based API security. \nWorking knowledge of containers, Kubernetes, and CI/CD pipelines. \nSound debugging skills across application, network, and gateway layers. \nClear written and verbal communication in English, including the ability to document APIs for other engineers. \nPreferred\nExperience with GraphQL federation and gRPC or Protocol Buffers. \nExperience with Kafka, Solace, or another event streaming or brokering platform. \nExperience integrating enterprise systems such as SAP, Salesforce, Veeva, Workday, or ServiceNow. \nExperience with developer portals, API catalogues, or API productization for external partners. \nExperience delivering within a regulated environment (GxP or other), including awareness of data-protection obligations such as GDPR. \nCertifications such as Kong, AWS or Azure developer level, or Certified Kubernetes Application Developer. \nA bachelor's degree in computer science, engineering, information technology, or a related discipline. \nCore Competencies\nDesign-led thinking with strong attention to interface quality \nConsumer focus and empathy for the developers who use your APIs \nSecurity awareness embedded in everyday engineering decisions \nBias toward reuse, standardization, and simplification \nPragmatic problem-solving under production pressure \nOwnership and follow-through \nContinuous learning and adaptability \nMeasures of Success\nIncreased reuse of published APIs and shared components \nReduced lead time from API design to production availability \nImproved conformance to enterprise API design and security standards \nComplete, accurate, and current API documentation in the catalogue \nImproved API availability, latency, and error rates against service levels \nFaster consumer onboarding and reduced support effort per API \nReduced number of undocumented, duplicate, or unmanaged endpoints \nPursue progress, discover extraordinary\nBetter is out there.
