Responsibilities

  • Work cross-functionally with Product/Design to translate ambiguous problems into measurable outcomes and shippable iterations. Lead the estimation of work at the quarterly level. Provide alternative solutions and negotiate with Product Management.
  • Build and ship LLM-powered product capabilities end-to-end: APIs, orchestration logic, integrations, and production rollouts
  • Design and implement agentic workflows (tool use, planners/routers, multi-step reasoning, handoffs, memory/state management) using modern orchestration frameworks (e.g., Lang Chain/Lang Graph-style)
  • Develop strong prompting + context engineering practices, including prompt versioning and experimentation (e.g., A/B testing approaches)
  • Build evaluation harnesses for LLM apps: curated test sets, automated checks, offline/online metrics, human review loops, and regression gates for changes
  • Collaborate with platform/infra teams to deploy on AWS, ensuring reliability, security, scalability, latency, and cost controls
  • Instrument systems for observability (quality, latency, token/cost, errors) and create feedback loops to improve model+system behavior over time
  • Develop high quality solutions
  • leads the creation of new standards, patterns, and best practices
  • Write architecture & design documentation for new products, systems, and patterns

Requirements

  • Engineering or Comp Science degree or equivalent work experience
  • 9+ years of professional experience in software engineering, applied ML, data science engineering, or AI product engineering
  • Some applied ML / data science experience (e.g., experiments, model evaluation, error analysis, feature work, or shipping ML-informed product changes), even if your recent focus has shifted toward software/AI engineering
  • Experience with cloud infrastructure (e.g. AWS) and shipping production workloads (containers, deployments, monitoring)
  • Prior role experience as a Data Scientist / Applied ML Engineer, with evidence of taking prototypes closer to production (directly or in close partnership with engineering)
  • Experience with LLM evaluation/observability tooling (e.g., experiment tracking, tracing, prompt/version management, continuous evaluation)
  • Familiarity with vector databases / retrieval systems and relevance tuning (RAG patterns, embedding selection, chunking strategies)
  • Experience with CI/CD, Docker/Kubernetes, or infrastructure-as-code
  • Strong Python skills, experience building backend services (e.g. Flask/FastAPI) and integrating with REST APIs
  • Practical understanding of LLMs/SLMs and how they behave in production (hallucinations, prompt sensitivity, latency/cost tradeoffs)
  • Hands-on experience building LLM applications (RAG, tool use, agents, workflow orchestration), with the ability to demonstrate end-to-end ownership from prototype‚ production‚ measurement, iteration
