Software Engineer

Full stack  |  AI  |  Client-facing delivery 

Do you have the skills — and drive — to join a tech team that’s working to digitally transform a trillion-dollar industry? From test-driving the latest technologies to creating intuitive consumer apps, Liberty Mutual is constantly innovating and creating industry-leading solutions that provide peace of mind for our customers worldwide. 

As a software engineer at Liberty Mutual, you’ll sit side by side with business partners to turn ambiguous problems into products that ship. You’ll own solutions end to end — from discovery and prototyping through production and support — in an agile environment that has the creative energy of a start-up and the full backing and comprehensive benefits of a Fortune 100 company. 

What you’ll do 

• Embedded partner: Work directly with business stakeholders and customers to scope problems, run discovery sessions and turn business goals into architectures and delivery roadmaps. 

• Rapid builder: Prototype quickly, validate with users and move the strongest ideas into production with confidence. 

• AI contributor: Help bring AI features, such as assistants and smart search, into the products you build. 

• Full stack developer: Build responsive web experiences in React and TypeScript, and scalable services and APIs in Node.js and GraphQL on Amazon Web Services (AWS). 

• Quality champion: Ensure quality through test- and behavior-driven development, automated testing and thoughtful code reviews. 

• End-to-end owner: Own the full lifecycle — requirements, architecture, implementation, release, observability and production support. 

• Forward thinker: Simply fixing the problem isn’t enough. You’ll continually look for ways to improve performance, quality, cost and efficiency — and measure, fix and re-verify as a habit. 

• Trusted advisor: Explain technical tradeoffs clearly to non-engineers, and document key decisions so teams can build on them. 

What you’ll bring 

• Three or more years of professional software engineering experience, including full stack development. 

• Hands-on experience in a forward deployed, client-facing or solutions engineering role, working directly with business owners or customers. 

• Strong proficiency in JavaScript and TypeScript. 

• Production experience building front-end applications with React. 

• Experience building back-end services and REST and GraphQL APIs with Node.js. 

• Experience deploying and running applications on AWS, such as Lambda, ECS, API Gateway, S3, DynamoDB or RDS. 

• Exposure to building with large language models (LLMs) or other AI services. 

• Familiarity with continuous integration and continuous delivery (CI/CD), DevOps tools, Docker and infrastructure as code. 

• Experience working in an agile environment using Scrum, Kanban or Extreme Programming (XP). 

• Strong oral and written communication skills — and a knack for explaining your decision-making process to non-engineers. 

• A collaborative, adaptable working style, demonstrated initiative and the ability to prioritize in ambiguous situations. 

Client-facing engineering skills 

• Discovery and scoping: Run stakeholder workshops, technical assessments and solution envisioning that translate business objectives into working software. 

• AI integration: Connect applications to LLM APIs and add retrieval-augmented generation (RAG) where it helps users. 

• Enterprise integration: Connect to existing systems through OAuth, webhooks, versioned APIs with rate limits and data pipelines. 

• Secure, multi-tenant design: Apply tenant isolation, role-based access and safe handling of customer data. 

• Cost and performance awareness: Track latency, reliability and cost, and tune solutions for production scale. 

Nice to have 

• Experience with AI platforms such as Amazon Bedrock or OpenAI. 

• Experience with Next.js, PostgreSQL and end-to-end testing tools such as Playwright or Cypress. 

• Experience with Kubernetes and container orchestration. 

• Insurance or financial services industry experience. 

• Certified Scrum Master or similar agile certification.
