Job description

We are an AI-led, platform-driven Digital Engineering and Enterprise Modernization partner, combining deep technical expertise and industry experience to help our clients anticipate what’s next. Our offerings and proven solutions create a unique competitive advantage for our clients by giving them the power to see beyond and rise above. We work with many industry-leading organizations across the world, including 20 Fortune 50 companies and 4 of the 5 top banks in both the US and India, and numerous innovators across the healthcare ecosystem.

We are seeking a skilled Java AI/ML Developer with strong expertise in Java, AI/ML technologies, and Cloud platforms to build scalable, intelligent, and cloud-native applications. The ideal candidate will work on developing AI-powered solutions, agent-based systems, and microservices architectures while collaborating with cross-functional teams to deliver innovative business solutions.

• Location: All Persistent Location
• Experience: 3 to 6 years
• Job Type: Full Time Employment

What You'll Do:

• Design and build Java/Spring microservices that support agent orchestration: tool
• invocation, session/state management, prompt routing, retrieval, and async workflows.
• Define service boundaries, APIs, and data contracts between agent runtime, business
• domains, and external tools (MCP, REST, messaging).
• Lead implementation of production-grade features: idempotency, retries, circuit breaking,
• rate limits, and graceful degradation when models or tools fail.
• Drive test strategy (unit, contract, integration, load) and CI/CD quality gates for agent pipelines.
• Troubleshooting and debugging to optimize performance
• Experience with databases directly, particularly MySQL and PostgreSQL, and how they are addressed by the application
• Comfortable working with and improving upon legacy systems and code as you are building new features and applications

Expertise You'll Bring:

• Strong Java (17+ preferred) with deep knowledge of OOP, concurrency, and JVM performance.
• Production experience with Spring Boot and service-oriented architecture.
• Solid API design (REST/OpenAPI); experience with event-driven or message-based systems.
• Proficiency with SQL/NoSQL, caching, and data modeling for high-throughput services.
• Experience building cloud-native services (AWS/GCP/Azure): containers, K8s basics, secrets, config, deployments.
• Strong testing discipline and operational ownership (on-call, incidents, postmortems).
• AI / agentic (demonstrable in production or substantial POCs)
• Hands-on experience building LLM-powered applications, not just calling APIs from scripts.
• Understanding of agent patterns: ReAct-style loops, tool calling, planners, sub-agents, and human approval steps.
• Experience with orchestration frameworks (e.g., LangChain4j, Spring AI, custom orchestrators, or equivalent).
• Practical knowledge of prompt engineering, structured output, and failure modes (hallucination, tool misuse, infinite loops).
• Familiarity with evaluation: golden datasets, regression tests for prompts/tools, offline vs online metrics.
• Awareness of security & compliance: PII handling, prompt injection, least-privilege tool access, audit logging.
• Competitive salary and benefits package
• Culture focused on talent development with quarterly growth opportunities and company-sponsored higher education and certifications
• Opportunity to work with cutting-edge technologies
• Employee engagement initiatives such as project parties, flexible work hours, and Long Service awards
• Insurance coverage: group term life, personal accident, and Mediclaim hospitalization for self, spouse, two children, and parents
