Software Engineer

About CoroCoro is Bain’s persistent product development and engineering organization serving the firm’s digital solutions across Commercial Excellence (B2B) and the newly established Demand Generation Suite (B2C). Coro brings together technology, data, and services to build and operate proprietary solutions that create differentiated value for Bain’s clients and case teams. This role sits within the newly established B2C pillar of Coro, building the technical foundation for Artemis – Bain’s AI-driven marketing and commercial investment allocation platform, and one of three products in the Demand Generation Suite. Job SummaryThe Software Engineer role is a full stack engineering position focused on building and maintaining product features across the Artemis backend (Python/FastAPI) and frontend (React/TypeScript). Engineers in this role contribute to platform capabilities used by consultants and clients in live engagements, working within established patterns and with guidance from senior team members. Contributions span both the API layer and the React components that surface those capabilities to users — including the marketing mix model configuration interface, channel allocation dashboards, scenario planning tools, and client-ready output views. This is a delivery-focused role for engineers who are ready to contribute meaningfully across the full stack and grow their ownership over time. The core expectation is shipping well-tested features within defined specifications, collaborating closely with senior engineers, and developing the habits and judgment that come with working in a production product environment. Additional responsibilities include participating in support and operations by identifying system defects, contributing to troubleshooting efforts, and supporting code deployments.
