WHO YOU’LL WORK WITH
Coro 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.
WHERE YOU’LL FIT WITHIN THE TEAM
The Staff Engineer I role is a full stack engineering position that builds end-to-end product features across the Artemis backend (Python/FastAPI) and frontend (React/TypeScript), ensuring the platform's user-facing capabilities are functional, reliable, and usable by consultants and clients in live engagements. Full Stack Engineers own specific feature areas within Artemis and the broader Demand Generation Suite product workstreams and are responsible for both the API layer and the React components that surface those capabilities to users. For Artemis, this includes the marketing mix model configuration interface, channel allocation dashboards, scenario planning tools, and client-ready output views.
This is a delivery-focused engineering role. The ability to ship complete, tested features independently — without waiting for a backend or frontend specialist to hand off — is the core contribution. Additional responsibilities include participating in support and operations by identifying system defects, leading troubleshooting efforts, directing code deployments, and mentoring junior engineers.
WHAT YOU’LL DO
Feature Development
Own and implement complete features spanning backend API logic and React frontend components for Artemis product areas. Take features from specification through to tested, deployed code across both layers.
Build and maintain backend routes for assigned product areas, ensuring request/response contracts are documented, versioned, and tested. Keep TypeScript type contracts on the frontend in sync with backend changes.
Frontend and Data Visualization
Build and maintain React components using the shared Demand Generation Suite design system, with a focus on marketing analytics interfaces: channel allocation dashboards, scenario comparison views, model configuration workflows, and executive-ready recommendation outputs.
Write and maintain database queries, schema migrations, and data access logic for Artemis data models. Optimize for the data volumes and access patterns typical of marketing analytics engagements.
Quality and Collaboration
Maintain and extend the backend and frontend test suites. Ensure new features ship with adequate test coverage and do not degrade existing functionality.
Participate in structured feedback sessions with Artemis Expert Consultants and go-to-market-aligned specialists to understand how tools are being used in live engagements, and translate that feedback into concrete improvements in subsequent sprints.
Strong interpersonal skills, able to work across all levels of the organization.
Support team in recruiting activities (resume screening, interviews, etc.).
Innovation & Emerging Technologies
Drive innovation through out-of-the-box thinking to solve critical business challenges and demands.
Participate in technical discovery, POCs, and innovation workstreams to validate new tools, technologies, and designs.
Investigate and keep up-to-date on emerging data, AI, and agentic technologies and trends; lead knowledge sharing.
Entrepreneurial spirit, willing to try new approache
