About the job

Requirements
  • Excellent programming and system design skills, with recent hands-on experience in Python and ideally one of C#/.NET, Java, Rust or C++.
  • A track record of taking AI or machine learning systems into production, including substantial experience with large language models, prompt design, agentic workflows, evaluation harnesses and retrieval pipelines.
  • Depth in surrounding engineering, including APIs and integrations, SQL, cloud platforms such as Azure or AWS, version control, continuous integration and continuous delivery, and security and access considerations for deployment in another organization's environment.
  • Proven ability to own a project from start to finish in an ambiguous setting, and the judgment to know what to build, what to buy and what to leave alone.
  • Experience working directly with clients or business stakeholders, including credibility to push back when the stated requirement is not the right one.
  • A strong academic background, with an undergraduate degree in computer science, mathematics, engineering or a related field.
Responsibilities
  • Embed within client teams to understand how work is done and frame business problems and commercial opportunities as AI problems, applying judgment to identify the true need beyond the stated requirement.
  • Lead delivery end to end: design, build, test, deploy and iterate AI solutions in live production environments.
  • Set the technical direction on engagements, making architectural decisions and defending them to client engineering and security teams.
  • Establish the technical foundations solutions depend on, working with client IT to secure the right integrations, access and hosting.
  • Prove value in production at small scale, then work with colleagues to productize and scale what works.
  • Build a pipeline of new use cases from observations on the ground, and help clients build their own capability rather than a dependency on the company.
  • Bring on other engineers as the work grows, and raise delivery standards through review, pairing and mentoring.
  • Challenge current systems and processes to achieve common goals through technical excellence and innovation.
  • Keep abreast of progress in AI and technology trends.
Desired Qualifications
  • Financial services experience is a bonus but is not essential.
  • Experience in one or more of C#/.NET, Java, Rust or C++ is ideal in addition to Python.

Simplify's Take

What believers are saying

  • Consulting drives growth: Mercer and Oliver Wyman's group grew 8% organically in the June 2026 quarter, versus 3% for broking.
  • Profits cushion jobs: Marsh kept about 27 cents of operating profit per sales dollar in 2025, before one-time costs.
  • Many career paths under one employer: 95,000+ colleagues span broking, reinsurance, benefits and strategy consulting in 130 countries.

What critics are saying

  • Expect cuts: Thrive, announced October 2025, sets aside $500 million, mostly severance and technology, to save $400 million yearly.
  • Pricing works against broking: Marsh's index shows commercial rates fell 6% in the June 2026 quarter, an eighth straight drop.
  • Back-office roles are being consolidated: a Business and Client Services unit is pooling operations and technology teams company-wide.

What makes Marsh & McLennan unique

  • Consulting is a third of the business: Mercer and the Oliver Wyman group earned 36% of 2025 revenue.
  • Investment management sets it apart: Mercer is the world's largest outsourced chief investment office, running portfolios for institutions.
  • Scale sets it apart: 2025 revenue grew 10% to $27.0 billion across broking, reinsurance and consulting.
