Liberty Mutual is seeking a Software Engineer to help build the Partner Platform—comprised of the Partner Portal and Switchboard—supporting our Strategic Partners in US Retail Markets. You will deliver the self-service experiences and shared gateway that partners use to onboard, manage, support, and expand their integrations with Liberty Mutual.

• Design and build modern front-end experiences for the Partner Portal using React and Type Script, creating reusable components and accessible, high-quality UIs.
• Develop and evolve RESTful APIs and serverless services on AWS; use CDK for infrastructure-as-code and event-driven patterns to support high request volumes.
• Engineer Switchboard’s common services layer, including authentication, routing, tokenization, feature access controls, and observability, with a focus on low latency and reliability.
• Apply secure-by-design principles; perform threat modeling and implement robust auth

• Implement comprehensive testing strategies, including unit, integration, and end-to-end tests for front-end applications.
• Collaborate across teams to coordinate releases, align on standards, and mentor peers; communicate technical concepts effectively to both technical and non-technical stakeholders.
• Continuously identify opportunities to improve performance, quality, developer experience, and partner onboarding speed.

• Excellent cross-team communication and collaboration skills; experience rolling out changes incrementally and non-disruptively (feature flags, canary releases, backward compatibility).
• Strong grasp of system architecture, design principles, agile engineering practices, and software development best practices.
• Bachelor’s or master’s degree in a technical field or equivalent professional experience.
