In this role, you will contribute to the design, development, and evaluation of AI and machine learning solutions that address complex, high-value business problems. You’ll work on well-defined problems and progressively take on greater ownership as you build your technical skills and judgment, supported by a team of experienced practitioners who are invested in your growth. This is a role with real responsibility from day one and a clear path to deeper autonomy as you develop.

This is a unique opportunity to work alongside experts in applied AI, statistics, and computer science. The team operates at the intersection of cutting-edge research and enterprise delivery, building AI solutions that shape the future of MassMutual and the life insurance industry at large. We partner closely with technology and business stakeholders across the organization, and we invest in growth through a culture of peer learning, candid feedback, and shared technical standards. The team is defined by a shared commitment to scientific and engineering excellence, meaningful work, and the kind of collaboration that makes challenging problems tractable. The Impact Develop, evaluate, and deploy AI and ML models and systems in support of defined business use cases, including LLM-based, generative and agentic AI, and classical machine learning approaches. Apply generative AI and agentic techniques (e.g., LLMs, RAG, prompt engineering) to real business problems, building and iterating on solutions under the guidance of senior practitioners. Conduct experiments and quantitative analyses to evaluate model and system performance, contributing to rigorous, evidence-based technical decisions. Build prototypes and contribute to production delivery of AI-powered applications, developing familiarity with the full lifecycle from ideation through deployment. Apply and grow proficiency in best practices for AI development, responsible AI, reproducibility, and production engineering standards. Communicate findings clearly to technical peers and stakeholders, translating analytical results into understandable and actionable terms. Contribute to team knowledge through documentation, peer feedback, and active participation in a collaborative, learning-oriented environment.
