AI Engineer

AI Engineer What We Need We're looking for a Senior AI Engineer to design and build production-grade agent and RAG systems that power intelligent, reliable automation across our platform. This role combines hands-on engineering with system-level thinking—owning everything from architecture and evaluation to scalability, observability, and reliability in production. The ideal candidate thrives in ambiguity, moves quickly from prototype to production, and brings a strong focus on quality, safety, and real-world impact. What You'll Do Agent Platform & Architecture Design and build core agent platform capabilities, including orchestration patterns (e.g., ReAct, Plan-and-Execute), tool execution layers, memory/context management, and guardrails Develop reusable agent skills and a standardized tool ecosystem aligned with platform conventions Implement enterprise-grade controls for agent execution, including human-in-the-loop workflows, permissioning, and policy enforcement Retrieval & AI Systems Design and implement RAG services, including hybrid retrieval, reranking, embeddings, and citation behavior Define evaluation frameworks and quality metrics to ensure grounded, reliable outputs Production Engineering & Reliability Build automated evaluation and regression pipelines to maintain quality at scale Establish observability (tracing, metrics, alerting) and optimize systems for latency, throughput, and cost Define best practices and incident response processes to ensure production readiness Applied Research & Technical Strategy Prototype and productionize emerging approaches (e.g., GraphRAG, knowledge graphs, MCP integrations) Evaluate AI frameworks and infrastructure (e.g., LangChain, LangGraph, AutoGen, LlamaIndex) and guide platform decisions Technical Execution Diagnose and resolve complex AI system issues (retrieval quality, hallucinations, prompt regressions, agent failures) Lead system design and drive technical decisions through hands-on prototyping and benchmarking What You Bring BS in Computer Science, AI, Electrical Engineering, or related field (advanced degree preferred or equivalent experience) 5+ years of software engineering experience, including building and deploying production-grade LLM, agent, or RAG systems Proven track record of shipping and supporting AI-powered features in production Strong Python skills (API design, testing, error handling, environment management) Working proficiency in C# or C++ Deep understanding of RAG system design and evaluation methodologies Experience building evaluation frameworks (test sets, metrics, regression pipelines) Understanding of LLM security risks (prompt injection, data leakage, agent misuse) Experience with graph databases, knowledge graphs, or GraphRAG preferred Experience designing human-in-the-loop systems and execution controls preferred Experience with agent frameworks (e.g., LangChain, LangGraph, AutoGen, LlamaIndex) You are able and willing to commute to our Burlington, MA headquarters twice a week on a hybrid schedule
