Establish and enforce API design standards, versioning strategies, and best practices across the organization
Optimize API performance, caching strategies, and response times for high-volume traffic (millions of calls daily)
Design and implement comprehensive API documentation, SDKs, and developer tools
Create MCP tool schemas, implement prompt best practices, and optimize tool discovery patterns
Collaborate with product and integration teams to define API contracts and service-level agreements (SLAs)
Implement monitoring, logging, and analytics for API usage patterns and performance metrics
Participate in code reviews and mentor team members on API and MCP best practices
Troubleshoot and resolve production issues in distributed API systems
Contribute to technical architecture decisions for API platform evolution

What You Bring:

Bachelor's degree in Computer Science, a related field, or equivalent practical experience
5+ years of experience in software development with strong focus on API development
3+ years of experience designing and implementing RESTful APIs and microservices at scale
Strong expertise in Java frameworks (Spring Boot, Spring Security, Maven/Gradle)
Strong expertise in NestJS framework
Deep understanding of OAuth 2.0, OpenID Connect, JWT, and API security best practices
Experience with API gateway technologies
Proficiency with API design patterns, versioning, and documentation (OpenAPI/Swagger)
Strong knowledge of rate limiting, throttling, and API scalability strategies
Understanding of distributed systems and high-availability architectures
Experience with MCP (Model Context Protocol) tool creation and implementation

Preferred Qualifications:

Experience releasing production MCP tools and servers
Deep knowledge of MCP best practices, prompt engineering, and tool design patterns
Familiarity with AI/LLM integration patterns and context management
Experience with cloud platforms (AWS, GCP, or Azure)
Knowledge of containerization and orchestration (Docker, Kubernetes)
Experience with CI/CD pipelines and automated API testing
Familiarity with message queuing systems (Kafka, RabbitMQ)
Experience building developer portals and API documentation platforms
Background in platform engineering or developer experience (DX) initiatives
Active contributions to open-source API projects or MCP tool repositories
