What youāll do (Key responsibilities):
ā¢ Translate product/solution blueprints into implementable technical designs and working software.
ā¢ Develop and maintain microservices and APIs that are secure, resilient, observable, and testable.
ā¢ Own the full SDLC: requirements refinement, design, implementation, code review, testing, CI/CD, deployment, and production support.
ā¢ Build agentic workflows using LLMs and frameworks (e.g., LangChain/LangGraph), including tool-use, retrieval, and orchestration patterns.
ā¢ Implement guardrails: prompt/version management, evaluation, safety checks, latency/cost controls, and fallbacks.
ā¢ Improve reliability through monitoring, logging, tracing, SLO-minded operations, incident response, and post-incident fixes.
ā¢ Collaborate with Product Engineering, Data Science, and Platform teams to integrate services into enterprise platforms and delivery pipelines.
Ways of working:
ā¢ Comfortable collaborating with product and architecture partners; can clarify ambiguity and deliver iteratively.
ā¢ Communicates clearly in design docs, PRs, and operational runbooks.
ā¢ Balances speed with reliability and quality; proactive about production health.
Typical Deliverables:
ā¢ Service design notes and API contracts
ā¢ Working microservices + tests + CI/CD pipelines
ā¢ Runbooks, dashboards, alerts, and production readiness artifacts
ā¢ Agentic workflow implementations (tools, routing, retrieval, evaluation)
