We are seeking an API Gateway Engineer with strong hands-on experience designing, building, securing, and operating API platforms using AWS API Gateway and/or Apigee. The role will focus on API lifecycle management, traffic governance, security (OAuth2/OIDC, JWT, mTLS), policy development, observability, and reliable CI/CD-based deployments. The ideal candidate will also bring full-stack development experience to help teams build and integrate backend services and modern web applications, and to drive best practices for API design, versioning, documentation, and performance.

• Build and manage API products, proxies, routes/resources, stages/environments, throttling, quotas, caching, and usage plans.
• Implement API security patterns: OAuth2/OIDC, JWT validation, API keys, mTLS, WAF integration, rate limiting, and threat protection.
• Develop and maintain gateway policies (Apigee policies / AWS authorizers, request/response transformations, validation, mediation).
• Build serverless and container-based integrations using AWS Lambda, ECS/EKS, and any backend services using any one of the programming languages such as Java/Spring Boot or Node.js or Python.
• Implement API governance: REST standards, naming conventions, versioning strategy, backward compatibility, and deprecation process.
• Create and maintain API specifications (OpenAPI/Swagger), documentation, developer portal content, and onboarding guides.
• Integrate API gateway with IAM, Cognito/Identity providers, secrets management, and certificate management.
• Set up end-to-end observability: logs, metrics, traces, dashboards, and alerts using any one of the platforms including CloudWatch, OpenTelemetry, ELK or New Relic.
• Diagnose and resolve production issues related to latency, throttling, auth failures, routing, certificates, and backend dependencies.
• Build and maintain CI/CD pipelines and automation (GitHub Actions/Jenkins, Terraform/CloudFormation, Maven/npm) for repeatable deployments.

What We're looking for

• Experience Required-5+ years in API
• Strong hands-on experience with AWS API Gateway (REST API / HTTP API), stages, deployments, custom domains, throttling, caching, usage plans, and integrations.
• OR strong hands-on experience with Apigee, including API proxies, policies, shared flows, environments, and deployments.
• Strong understanding of REST API design and best practices; experience with OpenAPI (Swagger).
• Solid experience implementing API security: OAuth2/OIDC, JWT, API keys, RBAC, mTLS, certificates, and integration with IdPs.
• Experience with backend integration patterns: synchronous REST, async/event-driven basics; request/response transformation and validation.
• Good proficiency in at least one backend language/framework (Java/Spring Boot or Node.js or Python).
• Full-stack understanding: ability to work with front-end frameworks (React or Angular) and connect to APIs.
• Experience with AWS fundamentals: IAM, VPC, CloudWatch, Lambda, S3, KMS, Route 53, ACM (certificates).
• Strong troubleshooting skills in distributed systems (timeouts, retries, rate limits, TLS issues, dependency failures).
• Strong communication and documentation skills for cross-functional work.
