AI Engineer

The role

You will own agents end to end, including the harness, tools, context, guardrails, and evals. You will design and ship production agents that perform transformation work across enterprise process, data, and code.

What you will do

• Design and ship production agents for transformation work
• Build the tool layer with typed, permissioned, and documented interfaces
• Improve agent performance through prompting, context construction, and tool-use strategy
• Build the retrieval layer over enterprise artifacts and metadata
• Manage context by deciding what the model sees, compresses, or drops
• Use classical ML for routing, ranking, classification, and anomaly detection
• Build the eval and monitoring layer with task sets and regression coverage
• Instrument every run for reconstruction and audit purposes
• Diagnose production failures from execution traces to root cause
• Design guardrails, approval gates, and rollback paths

Required qualifications

• 3+ years building and operating production software
• Meaningful recent time on LLM-powered systems
• Shipped agentic systems that real users depend on
• Owned the incident when agentic systems broke
• Fluent in the current agent toolkit including tool calling, orchestration, context engineering, RAG, evals, and tracing
• Built retrieval systems against messy real-world corpora
• Real traditional ML background in supervised learning, feature engineering, and model evaluation
• Write strong Python
• Comfortable in TypeScript

Nice to have

• Hands-on experience with enterprise platforms, their APIs, and their extension models
• Experience with knowledge graphs, ontologies, or semantic models
• Experience with code analysis, program transformation, or automated refactoring at scale
• Experience with MCP, sub-agents, or agent skill/plugin architectures
• A background in distributed systems or workflow engines
• Experience at an early-stage startup or as a founder
• Familiarity with enterprise security and compliance realities
