General InformationJob TitleDirector, Full stack AI EngineerJob ID111270Work AreasTechnology & EngineeringEmployment TypePermanent Full-TimeLocation(s)Boston, Chicago, London, Sao Paulo, WarsawDescription & RequirementsWhat Makes Us a Great Place to WorkWe 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 WithYou 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 engineers who see how to make a product better 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 real-time decision engines, cloud-native infrastructure, and data problems with no off-the-shelf answer. Experience with agentic systems matters: tool and context protocols such as MCP, evaluation harnesses, memory design, and entity resolution across messy enterprise data. This is applied AI in production, at scale, with real users depending on what you build. 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 TeamThe Full-stack Engineer owns the build and operation of the product interfaces and backend services that surface Growth AI Performance System capabilities to users across the full suite: the dashboards, workflow tools, scenario planning interfaces, and output views that Expert Consultants, specialists, and senior client stakeholders use in live commercial engagements. This is a platform-wide role within the Agentic Core and Interface team: you are building for all three product modules, not for one.You will work closely with the Design Lead and Designer on the front-end, with AI Engineers on the integration of agentic and LLM-powered capabilities into the interface layer, and with the Data Engineer on the data access and API layer that feeds what users see. You are responsible for the quality, reliability, and performance of the full stack: from the API surface that serves domain model outputs through to the React components that render them for users.This is also a people-leadership role. You will be the line manager for a small team of mid- to senior-level engineers within the Agentic Core and Interface team, owning their day-to-day work, performance, and growth: running weekly check-ins, serving as the point of escalation, writing mid-year and annual performance reviews, and setting professional development plans that build the team’s fluency with AI-assisted engineering practices.You will work across the platform and product modules focused on marketing ROI, brand, and pricing strategy, building interfaces that make complex analytical outputs navigable and credible for professional users who need to act on them quickly. The users of this product are sophisticated; the interfaces need to be fast, dense, and unambiguous.This role has direct client proximity. You will engage with consulting teams to understand how the interfaces are being used in live engagements, where performance or reliability is creating problems, and what engineering changes are needed.What You’ll DoBuilding and shipping product interfacesBuild and ship end-to-end product features across the Growth AI Performance System frontend: React and TypeScript component development, API integration, and the full feature lifecycle from design handoff through to production deployment and ongoing maintenanceOwn specific feature areas and interface workstreams across the suite: channel allocation dashboards, scenario planning and what-if tools, marketing ROI output views, brand analytics interfaces, and pricing strategy displays, designed for expert users who need to navigate dense analytical content quicklyBuild data-dense, chart-heavy interfaces using modern visualization libraries; implement time series views, waterfall charts, allocation comparisons, multi-variable scenario tools, and real-time output displays that update as model inputs changeImplement human-agent interaction components in collaboration with the AI Engineering team: how agentic recommendations, confidence indicators, scenario outputs, and uncertainty are surfaced to users in interfaces that are clear, credible, and professionally appropriateBuild and maintain the backend API layer that serves domain model outputs, agentic workflow results, and platform data to the frontend; design APIs that are reliable, versioned, and performant at production scaleEngineering quality and platform standardsLead the engineering implementation of the Growth AI Performance System design system: build component libraries that faithfully implement design specifications, maintain them as the design system evolves, and establish engineering conventions that make the frontend codebase consistent and maintainable across the full suiteWrite clean, testable, maintainable code across the full software development lifecycle; implement CI/CD pipelines, automated testing, and deployment workflows that support rapid iteration without sacrificing production stabilityOwn performance and reliability for the interface layer: monitor frontend performance, API latency, and error rates; diagnose and resolve issues that affect the user experience in live client deploymentsApply DevSecOps principles across the full stack: authentication and authorization, secure data handling for client commercial data, and compliance with privacy obligations relevant to the platform’s enterprise client contextMentor engineers on the team, including the Data Engineer; set engineering standards, provide structured code review feedback, and create opportunities for team members to take on progressively more ownershipPeople management and team leadershipManage a small team of mid- to senior-level engineers day-to-day: run weekly check-ins, unblock work, and serve as the point of escalation for technical and delivery issuesOwn the full performance cycle for direct reports: write and deliver mid-year and annual reviews, set goals, provide constructive feedback, and build individual professional development plansBuild AI/ML fluency across the team: set expectations for AI-assisted development practices, identify skill gaps, and guide reports’ growth into AI-augmented engineering rolesLead recruiting for the team: define hiring needs, participate in interviews, and own onboarding so new engineers reach full productivity quicklyCreate and foster a high job-satisfaction environment that supports continued growth and advancement for the team, while managing conflict and cross-team dependencies to keep delivery on trackCollaboration and communicationEngage with consulting teams during and after live client deployments to understand where the interface layer is creating friction, performance problems, or credibility issues;
