Boston, Chicago, London, Sao Paulo, Warsaw Description & Requirements What Makes Us a Great Place to Work We are proud to be consistently recognized as one of the world’s best places to work. We are currently the top ranked consulting firm on Glassdoor’s Best Places to Work list and have earned the #1 overall spot a record seven times. Extraordinary teams are at the heart of our business strategy, but these don’t happen by chance.

They require intentional focus on bringing together a broad set of backgrounds, cultures, experiences, perspectives, and skills in a supportive and inclusive work environment. We hire people with exceptional talent and create an environment in which every individual can thrive professionally and personally.

Who You’ll Work With You will be part of a team building Bain’s integrated suite of agentic decisioning tools that gives large organizations always-on intelligence across their most important growth decisions. The role sits at an intersection few organizations can offer: the analytical depth and client access of a top-tier consultancy, the technical ambition of a product company, and engineering work at the frontier of applied AI.You

will work inside Bain’s standing product team, building software that helps the world’s largest companies answer the questions that drive their business: where to invest, where to focus, and how to win. The impact of what you build is direct and immediate, and the platform compounds in value with every release.

The platform has two layers working together: an agentic core and a set of decision modules, each solving a distinct commercial problem. The build lifecycle is connected to the real world: as case teams work alongside clients across industries and geographies, that feedback flows straight back to engineering and into the product. Every client engagement makes the platform smarter, broader, and more resilient.

This is a startup inside an established company. You get genuine early-stage ownership and real influence over architecture and product direction, backed by Bain’s global scale, client relationships, and leadership commitment; the pace of a startup with the runway of a global firm.

We are looking for engineering leads who see how to make the platform’s evaluations sharper and bring that instinct to every sprint without being asked, and who are comfortable with problems that do not have a known answer. The work involves building evaluation frameworks for LLM-based and agentic systems, systems integration testing, and data problems with no off-the-shelf answer.

Experience with agentic systems matters: tool and context protocols such as MCP, evaluation harnesses, and entity resolution across messy enterprise data. This is applied AI in production, at scale, with real users and a team depending on how you approach problems that do not have a known answer. The field is moving quickly and the team is built to move with it, so the willingness to keep learning counts for as much as what you already know.

Where You’ll Fit Within the Team The AI Engineering Lead, Evals and Systems Integration, owns the evaluation framework and systems integration layer across the entire Growth AI Performance System platform. This is a cross-cutting role: you are not evaluating a single agent or a single module, but the coherence, quality, and reliability of the full system: from the data ontology layer through the Agentic Core to the three product modules that clients use.

Your work is the quality gate that determines what is ready to ship and what is not.
