As the premier consulting partner for the private equity industry, Bain's PEG boasts a global practice that is over three times larger than any competitor. Our network of over 1,000 professionals supports private equity and institutional investor clients through every stage of the investment life cycle, from deal generation and due diligence to portfolio value creation and exit planning.

Bain & Company is developing a suite of cutting‑edge data and software solutions designed to revolutionize how the private equity industry uses data for investment insights and decision‑making.

The PEG Innovation team's mission is to create analytical solutions for Bain clients, teams, and the broader institutional investor space using proprietary software and data products. This includes the development, commercialization, and daily management of Bain's proprietary datasets, data, and software businesses.

Full-Stack Type Script Engineer, AI Products build and deliver end-to-end AI product experiences across the PE due diligence ecosystem. This role sits at the intersection of product engineering and applied AI, combining solid full‑stack software engineering with practical knowledge of how LLMs and agentic systems behave in production.

This role is Type Script‑first. Most of the analyst‑facing product surfaces and Node.js services on the Workstream team are built in Type Script, and we expect this engineer to own and extend that stack end‑to‑end. Python remains a strong co‑requirement for the AI orchestration and pieces within our backend layer (Lang Graph, FastAPI, agent services), so candidates must be comfortable working productively across both ecosystems even where Type Script is their primary depth.

You will build intelligent product features from backend services through frontend experience, contributing to the workflows, orchestration layers, and user interfaces that make AI useful, reliable, and intuitive for end users. This includes implementing agent workflows, retrieval pipelines, evaluation gates, human‑in‑the‑loop review patterns, and the analyst‑facing experiences that surface them. You are technically strong in production AI systems and capable of translating non‑deterministic model behavior into clear, trustworthy product experiences with guidance from senior engineers.

You will contribute to engineering standards, participate in code reviews, and grow your expertise in building safe, observable, and scalable AI‑powered workflows.

• Build end-to-end AI product features across Type Script frontend experiences, Type Script/Node.js backend services, and Python‑based AI orchestration layers.
• 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 in Type Script (Svelte, React, Next.js, or similar) for streaming AI responses, structured outputs, source grounding, review and approval flows, and human‑in‑the‑loop interactions.
• Build and operate Type Script/Node.js backend services that power AI product features, including API endpoints, orchestration glue between frontend experiences and Python‑based agent services, and the data access layer (Postgres) that backs them.
• Implement full‑stack application patterns for chat, copilot, workspace, and review‑based AI experiences, including state management, real‑time updates, and error handling.
• Collaborate with Product, Design, and domain stakeholders to translate AI capabilities into intuitive, polished user experiences.
• Design and maintain end‑to‑end type‑safe contracts between Type Script frontends and Type Script/Python backend services, ensuring outputs are structured, testable, and resilient.
• Support contribution workflows and product surfaces for the Prompt Execution Sandbox and AI Artifact Studio, enabling safe and scalable use by non‑engineers where…
