Responsibilities

Design and ship production agents for understanding enterprise landscapes, planning and executing transformations, and proving correctness.
Build typed, permissioned tool interfaces that let agents read and act across enterprise systems within human-approved authorization limits.
Improve agent performance through prompting, context construction, tool-use strategy, and decision logic.
Build retrieval systems using chunking, indexing, hybrid search, reranking, grounding, and evaluation.
Manage context across long agent runs by deciding what to expose, compress, or discard.
Apply supervised ML, feature engineering, ranking, classification, anomaly detection, and confidence estimation where appropriate.
Build evaluation, regression, monitoring, tracing, and alerting systems for agent deployments.
Instrument and diagnose production runs down to root cause, then improve the system rather than isolated prompts.
Design guardrails, approval gates, auditability, and rollback paths for safe enterprise execution.
Generalize customer-specific capabilities into reusable product primitives.

Requirements

3+ years building and operating production software, including meaningful recent experience with LLM-powered systems.
Experience shipping agentic systems that real users depend on and owning production incidents.
Fluency with tool calling, orchestration, context engineering, retrieval-augmented generation, evaluations, and tracing.
Experience building and measuring retrieval systems over messy real-world corpora.
Background in traditional ML, including supervised learning, feature engineering, and model evaluation.
Strong Python skills and comfort with TypeScript.
Ability to build reliable systems around non-deterministic model behavior and think in terms of systems and customer outcomes.
