API Platform Engineer

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
