Senior Developer/ Leads with Java, Python + Google ADK, comfortable working with LLMs, MCP, building Agents, generating code


Role Summary
  • Design and build secure, scalable backend services in Java (Spring Boot) and Python, and deliver production-grade AI agent capabilities using Google Agent Development Kit (ADK).
  • Build agentic workflows that can use tools, maintain session context/memory, and generate/refactor code with strong human-in-the-loop review and governance.
  • Integrate agents with enterprise systems and data sources via Model Context Protocol (MCP) and standard APIs, with strong attention to security, observability, reliability, and cost controls.
Key Responsibilities
  • Develop high-scale microservices and APIs using Java 17+, Spring Boot, and REST/gRPC; apply solid engineering fundamentals (OOP, concurrency, performance).
  • Build Python services (e.g., FastAPI) that host agent logic and AI integrations; implement robust error handling, retries, and structured outputs.
  • Create and orchestrate agents using Google ADK: define agents, attach tools/functions, manage sessions and memory, and implement multi-step workflows (sequential/parallel/routed).
  • Implement MCP-based integrations: expose internal tools/resources as MCP servers (where applicable) and consume MCP tools from agents/clients securely.
  • Deliver LLM features (tool/function calling, prompt & context engineering, evaluation) and implement RAG patterns with embeddings and vector databases when grounding is required.
  • Containerize and deploy services using Docker and Kubernetes (AKS/OCP preferred); build CI/CD pipelines (GitHub Actions/Jenkins/Harness) with quality gates.
  • Implement observability (logs/metrics/tracing), SLOs/SLIs, and performance testing; participate in incident response and root cause remediation.
  • Mentor engineers, perform design/code reviews, and collaborate with product, security, data, and platform teams in an Agile/Scrum environment.
Must-Have Skills
  • Strong Java backend engineering (Java 17+, Spring Boot, microservices, REST/gRPC).
  • Strong Python engineering (OOP, typing, async patterns, packaging) and service development.
  • Hands-on experience building agents and workflows with Google ADK (agents, tools, sessions/memory).
  • Comfort working with LLMs: tool/function calling, structured outputs, prompt & context engineering, safety considerations.
  • Understanding of MCP concepts (resources, tools, prompts; client-server model) and ability to integrate tools using MCP or standard APIs.
  • Ability to produce high-quality code with AI-assisted code generation, plus strong review/verification and testing discipline.
  • Security fundamentals: OAuth2/OIDC, JWT, secure coding, secrets management; familiarity with mTLS/cert management is a plus.
  • Cloud-native fundamentals: Docker, Kubernetes; CI/CD pipelines; basic monitoring/observability.
Good-to-Have Skills
  • LangChain/LangGraph or similar orchestration frameworks; experience combining them with ADK where useful.
  • Vector DB experience and RAG evaluation practices.
  • GCP/Vertex AI (or other cloud LLM hosting) and production deployment patterns (Cloud Run/Agent Engine).
  • Kafka/Flink or event-driven architectures for real-time systems.
  • Front-end exposure (React/Angular) for agent-driven UIs or developer tooling.
