Job Introduction
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. Your work will enable product access controls, onboarding workflows, documentation, and operational tools that reduce time-to-market and maintenance cost, while providing a single, secure, and performant entry point to Liberty Personal Lines quoting and post-bind APIs.
If you're passionate about building secure, scalable systems and great developer experiences, we want to hear from you.
What You'll Do
- Design and build modern front-end experiences for the Partner Portal using React and TypeScript, 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 authN/authZ for partner-facing services.
- Instrument systems for observability (logs, metrics, traces) and operational excellence; build dashboards and alerts in Splunk and Datadog.
- 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.

- Strong proficiency in JavaScript/TypeScript and React; experience with end-to-end testing of front-end applications (e.g., Cypress, Playwright).
- Hands-on experience with AWS architecture and serverless: CDK, event-driven design, Lambda fundamentals (cold starts, concurrency, timeouts), and building for scale.
- Solid ability to translate requirements into clear designs and implementation plans; comfortable designing solutions that can be worked on by multiple engineers.
- Strong knowledge of RESTful API design and development; familiarity with API versioning, idempotency, pagination, and error handling.
- Familiarity with security and threat modeling; experience with authentication and authorization patterns (e.g., OAuth 2.0, JWT), and tokenization.
- Experience with observability tooling; familiarity with Splunk and Datadog for logs, metrics, tracing, dashboards, and alerting.
- Understanding of functional programming concepts and when to use them versus object-oriented approaches.
- 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.
