This role sits at the intersection of product engineering and applied AI, combining strong full-stack software engineering with deep practical knowledge of how LLMs and agentic systems behave in production.WHAT YOU'LL DOYou will own intelligent product features from backend orchestration through frontend experience, building the services, workflows, and user interfaces that make AI useful, reliable, and intuitive for end users. This includes designing agent workflows, retrieval pipelines, evaluation gates, human-in-the-loop review patterns, and the analyst-facing experiences that surface them. You are deeply technical about production-grade AI systems, but equally strong in translating non-deterministic model behavior into clear, trustworthy, and effective product experiences.You will mentor other engineers, raise standards for AI product engineering, and help define how Bain builds safe, observable, and scalable AI-powered workflows.Full-Stack AI Product Engineering (60%) Design and build end-to-end AI product features across backend services, orchestration layers, and frontend user experiences. Develop analyst-facing and internal AI interfaces for workflows such as deal screening, commercial due diligence research, document extraction, and portfolio monitoring. Build responsive, high-quality frontend experiences for streaming AI responses, structured outputs, source grounding, review and approval flows, and human-in-the-loop interactions.Implement full-stack application patterns for chat, copilot, workspace, and review-based AI experiences, including state management, real-time updates, and error handling. Partner closely with Product, Design, and domain stakeholders to translate ambiguous AI capabilities into intuitive, polished user experiences. Design and maintain stable contracts between frontend applications and AI/backend services, ensuring outputs are structured, testable, and resilient. Build contribution workflows and product surfaces for the Prompt Execution Sandbox and AI Artifact Studio, enabling safe and scalable use by non-engineers where required. Ensure AI product features are accessible, observable, and production-ready, with strong attention to usability, reliability, and edge-case handling.AI Platform and Agent Workflow Engineering (40%)Design and build the Agent Gateway service, including inbound APIs, model routing (including Azure OpenAI Service endpoints), context management, response validation, and cost/audit logging. Build and maintain LangGraph agent workflows for PE use cases, including streaming, tool-calling, multi-step execution, and human-in-the-loop interrupt patterns. Integrate Temporal durable execution with LangGraph, including workflow and activity authoring, checkpointing strategies, retry and backoff policies, signal/query handling, and safe versioning for in-flight workflows. Build and maintain AI platform services such as Agent Session Manager, Memory Service, HITL Coordination Service, and Feedback/Correction Service with production SLO expectations. Design and implement RAG pipelines end-to-end, including chunking strategies, embedding model selection, vector store integration (Azure AI Search and/or pgvector), re-ranking, and retrieval quality evaluation. Own evaluation and regression gates, including golden dataset management, metric definition, qualitative and quantitative evaluation, LangSmith/Braintrust integration, and CI enforcement on quality regressions. Implement context window management strategies such as token budgeting, truncation/compression, and tool-call state persistence to support reliability in longer-running workflows. Instrument AI services with structured logging, traces, and metrics, and define operational dashboards and alerts for latency, quality, cost, and failure signals. Deploy and operate AI workloads in Kubernetes, including containerization, Helm-based deployment patterns, and autoscaling considerations where appropriate.Leadership, Collaboration, and Engineering Standards Mentor engineers and help set standards for production AI product engineering across testing, evaluation, documentation, safety constraints, and maintainability. Partner with Data Platform on feature store access patterns, inference integration, schemas, data contracts, and SLAs. Collaborate with Product Engineering and Design on AI feature surfacing, including streaming experiences, structured output rendering, citation and evidence UX, and HITL review interfaces. Use AI coding assistants to accelerate prototyping and development, while validating all production artifacts against testing and evaluation gates before promotion. Document agent behavior specifications, tool contracts, and product interaction patterns so behavior is explicit, reviewable, and maintainable.ABOUT YOUBachelor’s degree in Computer Science, Engineering, Information Systems, Data Science, or a related field, or equivalent practical experience. 6+ years of experience building production software, including significant experience delivering full-stack applications and/or AI-enabled systems in production environments.
