WHAT YOU’LL DO

• As an Expert Manager, Software Engineering, you will lead the development and building of software applications that address complex business and technology problems in various industries. You will guide a diverse engineering team through the entire engineering life cycle. Your responsibilities will include designing, developing, optimizing, and deploying cutting-edge software engineering solutions and infrastructure at the production scale required by the world’s largest companies, with a strong focus on ensuring technical delivery supports business strategy, operating model evolution, and sustainable value creation.
• Shape & scope client solutions. Work with Bain consulting teams and product owners to translate business problems into prioritized backlogs and technical roadmaps for cross-functional engineering squads
• Translate technical capabilities into client-ready product and transformation outcomes by shaping product direction, operating model implications, and change management approaches that support adoption and measurable business impact
• Own full-stack design & build. Lead the architecture, development and documentation of AI applications, including coding and integrating third-party services or frameworks that accelerate delivery and long-term maintainability
• Establish AI-native software engineering best practices. Define and enforce standards around component libraries/design systems, automated testing, linting, CI/CD, accessibility and performance optimization
• Develop reusable libraries & accelerators. Create and curate shared code assets that reduce time-to-value across multiple client projects and internal initiatives.
• Lead the full delivery lifecycle. Set quality gates, supervise code reviews, ensure robust unit/integration test coverage, manage release planning, and oversee post-deployment monitoring and incident resolution
• Partner on UI/UX excellence. Collaborate with designers to ship inclusive, responsive interfaces
• Mentor & grow engineers. Provide day-to-day technical coaching for senior and mid-level engineers through pair programming, architecture sessions and constructive feedback
• Upskill client engineering teams. Coach client developers on modern tooling and DevOps/cloud-native practices, ensuring sustainable ownership after Bain’s engagement
• Advance AI-native technology adoption. Champion containerization, infrastructure-as-code, automated observability and secure-by-design principles to improve scalability, reliability and security
• Contribute to communities of practice. Share lessons learned and emerging technology trends through internal forums, brown-bag sessions and knowledge assets
• Support talent acquisition & onboarding. Participate in interviewing, technical assessments and mentoring of new hires to build a high-caliber engineering cohort
• Travel is required. This position requires regional travel away from your home office/primary working location. Travel frequency and destinations will vary based on project needs
