Responsibilities
- Design and implement specialized AI services and agents with data serialization, retrieval, memory, tool integrations, and bounded multi-step reasoning.
- Define expected AI behavior, build representative test sets and evaluations, track regressions, and use results to measure and improve quality.
- Improve context, data, service logic, tools, and model behavior through evaluation findings, failure analysis, and production feedback.
- Integrate tracing, observability, versioning, monitoring, reliability practices, and success metrics into owned services.
- Run controlled, repeatable experiments comparing models, data, and implementation approaches.
- Partner with AI Architecture, AI Ops, and Platform teams to build secure, reliable, cost-aware, and scalable services.
- Iterate from user problem to prototype to production and learn from real workflow outcomes.
Requirements
- 5+ years of software engineering experience delivering production services or products, ideally at senior or staff level.
- Hands-on experience building AI or LLM-powered applications or agents used by real users or in operational settings.
- Experience defining expected AI outcomes, building evaluations or test sets, tracking regressions, and acting on results.
- Ability to shape retrieval, context, and serialization so models receive the information needed for a task.
- Good judgment regarding tool use, autonomy, human review, failure handling, privacy, reliability, latency, and cost.
- Product-minded approach focused on solving workflow problems and measuring outcomes.
- Comfort learning tools and frameworks; experience with agent runtimes, model APIs, MCP, tracing, or evaluation tools is helpful.
