The Senior AI Engineer role focuses on designing and delivering production AI systems, managing architecture decisions, and ensuring the reliability and performance of AI capabilities.
Responsibilities
- Design and delivery of production AI and agentic systems across document intelligence, workflow automation, and copilots
- Architecture decisions for LLM-based systems, including retrieval, tool use, orchestration, memory, and evaluation
- Evals and observability for production AI. You own how we know the system is working and how we catch it when it is not
- Cost and latency management at production volume
- Partnership with AI product on scoping and sequencing features
- Partnership with data engineering on the pipelines, schemas, and data quality your systems depend on
- Technical mentorship of other engineers working on AI-adjacent systems
- Vendor and model evaluation, including POCs, benchmarks, and cost-performance tradeoffs
Skills
- 6+ years of software engineering experience, with at least 2 years focused on shipping production LLM-based or ML systems
- Demonstrated experience building and deploying agentic systems, including tool use, orchestration, and multi-step workflows
- Strong Python proficiency, including production-grade code quality, testing, and deployment practices
- Hands-on experience with LLM APIs (Anthropic, OpenAI, AWS Bedrock, or similar), including prompt design, structured outputs, and function calling
- Production experience with evals and observability for LLM systems. You know how to measure accuracy, detect regressions, and monitor drift

- Fluency with cloud infrastructure (AWS preferred), including serverless, containers, and API design
- Clear written and verbal communication skills with the ability to write design docs, explain tradeoffs, and collaborate with product and engineering peers
