Senior AI Engineer (Remote, Contract)

Role overview

The engineer works across the full product lifecycle, translating business needs into measurable outcomes and owning reliability, quality, cost, and improvement after launch.

Responsibilities

- Build agentic workflows involving tool use, structured outputs, retrieval-augmented generation, multi-step orchestration, and human review. - Create and maintain governed tool layers and MCP servers that connect agents to business data and systems. - Establish evaluations, golden datasets, telemetry, prompt and model versioning, provider routing, fallbacks, and cost controls. - Deliver production services through testing, CI/CD, containerized deployments, monitoring, and rollback processes. - Contribute to shared AI platform capabilities such as agent templates, LLM gateways, and observability. - Partner with stakeholders to prioritize use cases, define success metrics, and determine when an agent is appropriate.
