API Platform Engineer (George)

Environment A leading Insurance Company is moving to an API-first architecture as part of a broader modernisation effort. They are implementing Azure API Management, establishing OpenAI standards, and building the developer portal that will make their APIs discoverable and usable. The API Platform Engineer is about creating the API layer that enables the strangler fig migration and future integrations.

Responsibilities

Define API design standards aligned with OpenAI 3.1 that actually get followed

Architect and manage Azure API Management (APIM) for all external and internal APIs

Create a versioning strategy that lets us evolve APIs without breaking existing consumers

Build API templates and code generators that make it easy to create consistent APIs

Implement API security: OAuth 2.0, JWT validation, rate limiting, IP restrictions

Set up contract testing so they catch breaking changes before they reach production

Build and maintain the API documentation portal. If it's not documented, it doesn't exist

Review every new API before it goes live. You're the quality gate

Create mock services so frontend teams can develop against APIs that don't exist yet

Define integration patterns for Group system connectivity

Requirements What You Bring

You've built and maintained API platforms at scale. You know what separates a good API from a bad one

5+ years in API development or API platform roles

Deep understanding of REST principles and pragmatic application of them

Azure API Management experience (or similar gateway experience)

You can write an OpenAPI spec from scratch and explain why every decision matters

Strong security background: OAuth 2.0, OpenID Connect, JWT, API threat modelling

C# and ASP.NET Core Web API proficiency

Experience with API testing tools: Postman, Bruno, Newman, contract testing frameworks

Education

Degree or Diploma in Computer Science, Information Technology, Software Engineering, Computer Engineering, or a related technical field.

Relevant certificates in cloud platforms, API management, or platform engineering (Azure preferred) will be advantageous.

Equivalent practical experience building and maintaining production APIs and distributed systems will also be considered.

Nice to Have

GraphQL or gRPC experience

Event-driven API patterns (webhooks, AsyncAPI)

Experience with Backstage or similar developer portals

Insurance integration experience (ACORD standards awareness)

You've evangelised API standards to resistant teams before
