Job summary

IT Minds LLC in Cary, NC seeks a hands-on API Architect to own the API layer end-to-end for our enterprise Azure Data Hub. The role blends architecture with development, focusing on contract-first design, OpenAPI standards, and scalable data interfaces.

Expect ~60% architecture/design and ~40% coding in Java with Spring Boot/WebFlux, Python automation, and cloud-native delivery, collaborating with architects, engineers, and system owners to deliver reliable, secure APIs.

Qualifications

10+ years in API, integration, or backend engineering.
3+ years owning API architecture and design at enterprise scale.
Strong hands-on experience with Java, Spring Boot, Spring WebFlux, and Project Reactor.
Deep knowledge of REST, OpenAPI, contract-first development, API versioning, pagination, error handling, and idempotency.
Experience with large-file transfer patterns such as SFTP, signed URLs, multipart and resumable uploads.

Responsibilities

Own the end-to-end API architecture, including service boundaries, contracts, data models, error handling, and versioning.
Design reusable API patterns for inbound/outbound interfaces, data exchange, file transfers, and synchronous/asynchronous workflows.
Define OpenAPI standards, naming conventions, payload structures, backward compatibility, and contract-first development.
Design reliable large-file transfer solutions using streaming, chunking, resumable transfers, signed URLs, and checksums.
Make architecture decisions around synchronous APIs, asynchronous messaging, and bulk file interfaces.
Design for scalability, resilience, backpressure, retries, idempotency, rate limiting, timeouts, and graceful degradation.
Design and develop reactive Java services using Spring Boot, Spring WebFlux, and Project Reactor.
Apply non-blocking I/O, reactive streams, backpressure, and streaming for large payloads.
Build reference services and reusable patterns for other engineering teams.
Use Python for automation, testing, contract validation, load testing, and operational tooling.
Participate in code reviews, pair programming, troubleshooting, and production support.
Design and deploy APIs using Azure App Service, AKS, or Azure Container Apps.
Implement Azure API Management for gateway policies, throttling, subscriptions, and API management.
Integrate APIs with ADLS Gen2 and enterprise data pipelines.
Design asynchronous integrations using Azure Event Hubs, Azure Service Bus, or Kafka.

Important

This is a hands-on architecture and development role. Candidates should have strong API Architecture experience and be capable of hands-on coding. The title does not have to be \"Architect.\" Senior API Engineers, Lead Engineers, or Technical Leads with strong API architecture and design experience can also be considered.

About The Role

We are building an enterprise Data Hub on Azure that ingests, curates, and serves data across a wide range of inbound and outbound interfaces.

We are looking for a hands-on API Architect to own the API layer end to end. The role will work closely with architects, engineers, and system owners to define interface contracts, architecture standards, and delivery patterns.

This is a design-and-build role, not a diagrams-only position. The ideal candidate will spend approximately 60% on architecture/design and 40% on hands-on engineering.

Key Responsibilities API Architecture & Design

Own the end-to-end API architecture, including service boundaries, contracts, data models, error handling, and versioning.
Design reusable API patterns for inbound/outbound interfaces, data exchange, file transfers, and synchronous/asynchronous workflows.

Azure & Integration

Design and deploy APIs using Azure App Service, AKS, or Azure Container Apps.
Implement Azure API Management for gateway policies, throttling, subscriptions, and API management.
Integrate APIs with ADLS Gen2 and enterprise data pipelines.
Design asynchronous integrations using Azure Event Hubs, Azure Service Bus, or Kafka.
Work with event-driven and CDC-based integration patterns.

Security & Governance

Design API security using OAuth2, OIDC, JWT, Entra ID, and managed identities.
Implement mutual TLS where required for partner integrations.
Use Azure Key Vault for secure secret management.
Implement private endpoints, network isolation, IP restrictions, and gateway security policies.
Define standards for PII protection, masking, tokenization, and encryption.
Implement contract testing, validation, reconciliation, and audit logging.

DevOps & Operations

Build CI/CD pipelines using Azure DevOps.
Implement automated unit, contract, and integration testing.
Use Terraform for Infrastructure as Code.
Implement monitoring, logging, distributed tracing, metrics, and alerting using Azure Monitor and Application Insights.
