About The Position

Looking for a position that makes you smile? We’re seeking an API Platform Developer II to join our growing team. The API Platform Developer II is responsible for building and supporting an enterprise API platform on Azure Functions and Azure API Management. This position delivers well-tested API capabilities, maintaining reliable operations, and improving developer experience through clear patterns and documentation. How you’ll make us better: Build and maintain Azure Functions using the .NET 8 isolated worker model and HTTP triggers Design and deliver REST APIs using OpenAPI-first principles with clear annotations and documentation Actively leverage AI‑assisted development tools to optimize day‑to‑day workImplement stored procedure-based data access against Azure SQL Managed Instance, including read-replica patterns where appropriate Apply caching strategies to improve performance and reliability Build and maintain shared libraries for common capabilitiesAssist with architecture decisions and capture key choices in lightweight Architecture Decision Records (ADRs) Improve performance and reliability by applying established patternsIntegrate with Azure services including Application Insights, Key Vault, Blob Storage, and Azure Identity Analyze and document existing MSSQL schemas to understand entity relationships, constraints, and data flows Develop and refine SQL queries and stored procedures so API responses are accurate, performant, and aligned to business logic Partner with data owners and DBAs to validate assumptions, coordinate model changes, and troubleshoot performance issues when needed Create reusable query templates and schema references to speed onboarding and improve consistency across services. Assess the impact of schema changes on existing APIs and coordinate versioning or data-access updates as needed Configure and maintain Azure API Management (APIM), including backend routing, policies, and subscription management Maintain APIM configuration for backend setup and policy updates, following established patterns and change controls Support API versioning for non-breaking changes and coordinate breaking changes that require new versions Implement throttling and rate limiting per subscription and operation Maintain APIM API definitions and ensure OpenAPI specifications stay in sync with deployed endpoints Monitor and troubleshoot API health and performance using Application Insights and APIM analytics Support external partner onboarding by provisioning APIM subscriptions and maintaining required mappings/records Maintain GitHub Actions workflows for build/test, OpenAPI generation, and multi-environment deployments Use deployment slots with controlled production swap patterns Support deployments across DEV and PROD environments by following the established release process Troubleshoot deployments and improve deployment automation scripts
