Help shape how generative AI creates value in commercial insurance
Liberty Mutual’s Global Risk Solutions (GRS) business provides commercial and specialty insurance solutions to organizations around the world. Within GRS Innovation, we explore emerging technologies and turn promising ideas into proofs of concept, initial pilots, and reusable engineering patterns.
Our work helps delivery teams solve meaningful business problems while reducing code complexity, testing challenges, and cognitive load. We partner closely with Engineering, Architecture, Data, Analytics, and business teams to determine where emerging capabilities—particularly generative AI—can deliver differentiated value.
Currently, we are advancing designs for an enterprise AI context plane: the patterns and capabilities used to provide AI solutions with relevant, governed, and reusable business context. In addition, the team has been instrumental in developing intelligent document processing capabilities that are central to current and future business-value plans.
We are looking for an inquisitive hands-on engineer who enjoys working at the intersection of experimentation and practical delivery. You will explore ambiguous problem spaces, rapidly asses & test new coding possibilities, and create credible paths from prototype to production.
What you’ll do
Build and validate emerging solutions

Create a path from prototype to production

Navigate complex and ambiguous problems

Influence and grow the engineering community

At the Principal level, you will also be expected to shape technical direction across multiple initiatives, influence architecture beyond the immediate team, and increase the effectiveness of engineers and teams through broadly reusable approaches.

Qualifications What you bring to the team
Experience:

Preferred qualifications

You are curious without being driven by novelty. You enjoy moving from an unclear problem to a working solution, but you also know that a successful experiment must produce reliable evidence and a practical adoption path.
You combine hands-on engineering depth with strong judgment and communication. You can build a prototype, challenge its assumptions, explain its tradeoffs to senior leaders, and help an application team understand how to take it forward. You value diverse perspectives and create an environment where teammates can learn, contribute, and do their best work.
If the opportunity interests you but your experience does not align with every preferred qualification, we encourage you to apply. We value relevant capabilities, learning agility, and the potential to make a meaningful impact.
Hands-on experience designing and building generative AI applications. We're looking for engineers who can build GenAI capabilities and best practices to solve real problems — going beyond engineers who use AI-assisted development tools well. Experience with relevant GenAI techniques and architectures, such as retrieval-augmented generation, agents and tool use, prompt and context engineering, model integration, and structured-output generation. Experience evaluating GenAI solutions for quality, reliability, safety, and business usefulness using repeatable testing and evaluation practices.
