About the role

Responsibilities:

  • Design and build production-grade LLM and agentic AI systems.
  • Extensive experience in context engineering and harness engineering.
  • Design agent workflows involving tools, APIs, retrieval, memory, policies, and human-in-the-loop escalation.
  • Build context engineering layers that retrieve, rank, structure, and manage business context for LLM applications.
  • Good to have exposure to the Rust programming language.
  • Develop prompt, tool, and workflow orchestration patterns for reliable AI behaviour.
  • Create evaluation harnesses for LLM applications, including regression tests, golden datasets, automated scoring, trace replay, and human review workflows.
  • Define and track metrics for task success, accuracy, cost, latency, safety, and reliability.
  • Integrate LLM systems with enterprise data sources, APIs, vector databases, search systems, and operational platforms.
  • Implement observability for AI systems, including tracing, prompt/version tracking, tool-call monitoring, and failure analysis.
  • Partner with product, data science, engineering, analytics, security, and business teams to convert ambiguous problems into scalable AI solutions.
  • Lead architecture reviews, mentor engineers, and establish best practices for LLM application development.
  • Evaluate models, frameworks, vendors, and infrastructure options based on quality, latency, cost, privacy, and maintainability.


Requirements:

  • 7 - 9 years of experience in Machine learning and data modelling.
  • Strong experience in machine learning engineering, software engineering, data science engineering, or AI platform development.
  • Hands-on experience building production ML, LLM, NLP, search, recommendation, or decision-support systems.
  • Strong Python programming skills and experience building production services or APIs.
  • Experience with LLM application patterns such as RAG, tool calling, structured outputs, workflow orchestration, or AI agents.
  • Experience designing evaluation frameworks for ML or LLM systems.
  • Understanding of prompt engineering, context design, retrieval quality, and model behaviour testing.
  • Experience with cloud infrastructure, CI/CD, monitoring, logging, and deployment practices.
  • Ability to reason about trade-offs across accuracy, latency, cost, reliability, privacy, and user experience.
  • Strong communication skills and ability to lead technical work across teams.
