Who you'll work with

Our McKinsey Value Intelligence team is a high-impact engineering and analytics squad. We operate on a micro-front-end architecture , and encourage our colleagues to use the best technology for the job - whether it's Golang , TypeScript, React, AWS, Postgres, MongoDB, Python, or anything else well suited. We're building tools that cut through complexity, and perform under heavy usage. If you love tackling tough challenges with smart, passionate teammates, this is the place to be.

Join our team and help redefine how companies create value. Our platform blends cutting-edge analytics, design thinking, and tech to drive real impact. Our team is at the forefront of this shift-building powerful software in collaboration with practice experts that help leaders cut through the noise and focus on what truly drives performance. By combining deep financial analytics with McKinsey's corporate finance expertise, we give our colleagues and clients the insights they need at scale, to unlock growth, optimize strategy, and maximize shareholder value.

  • Champion best engineering practices - clean code, design patterns, CI/CD, security, and high scalability .
  • Collaborate closely with business, design and product teams to translate complex challenges into elegant technical solutions.
  • Thrive in an Agile environment, where adaptability and problem-solving are key.

General Engineering & Leadership
