Description

Hiring Manager: Chris Mulligan

We’re building the next-generation personal-lines quoting platform and are seeking a Principal Software Engineer to design, build, and operate AWS-native services that power roughly 80% of our direct-channel quoting volume. You will join a Quoting Platform team in the Distribution portfolio within the USRM Technology organization and develop and maintain reusable APIs and microservices that support Digital Sales, Olympus (DRC), and the Strategic Partnership Group (SPG) for new-business quoting and binding. This is a technical leadership role with hands-on delivery, architecture influence, and cross-team collaboration.

Responsibilities

  • Design, implement, and operate highly available, scalable microservices and reusable APIs that support the insurance quoting and binding lifecycle.
  • Lead architecture, design reviews, and system design for complex integrations and platform initiatives.
  • Build and maintain services across TypeScript/Node.js and Java codebases running on AWS (Fargate, Lambda).
  • Model and manage data using DynamoDB and DocumentDB (or equivalent) and ensure data reliability and performance.
  • Drive cross-team integration with Digital Sales, Olympus (DRC), and SPG; ensure APIs meet product and partner needs.
  • Mentor and coach engineers, promote best practices in testing, deployment, security, and observability.
  • Participate in incident response, root cause analysis, and continuous reliability and performance improvements.
  • Evaluate, adopt, and standardize engineering tools, automation, and CI/CD practices across teams.

Qualifications

  • Bachelor’s degree in a technical or business discipline, or equivalent experience.
  • Minimum 8+ years of software engineering experience, including production delivery of large-scale distributed systems.
  • Hands-on experience with Java and TypeScript/Node.js; full-stack experience is a plus.
  • Experience Spring Boot, or similar event-driven and Java frameworks.
  • Proven experience building and operating services on AWS (Fargate, Lambda, S3, IAM best practices).
  • Practical experience with NoSQL data stores, especially DynamoDB; familiarity with DocumentDB or MongoDB.
  • Strong debugging, troubleshooting, and performance-tuning skills.
  • Deep understanding of distributed systems, service integrations, and automation frameworks.
  • History of leading complex technical initiatives across multiple systems or integration layers and influencing technical direction without formal authority.
  • Experience working across teams to standardize engineering approaches and enterprise platform considerations (security, identity, scalability).

Preferred (Nice-to-have)

  • Prior exposure to the insurance quoting lifecycle, underwriting, or digital sales integrations.
  • Hands-on familiarity with AI-assisted engineering tools or prompt engineering techniques (e.g., GitHub Copilot, LLM-based assistants) and experience evaluating such tools for enterprise adoption.
  • Experience evaluating or adopting engineering tools/platforms at scale.

Why join us You’ll shape a core platform that powers the majority of our direct quoting volume, work with modern cloud-native technologies, and make a measurable impact across multiple distribution channels. This role offers the opportunity to lead architecture and operational excellence, influence cross-functional product delivery, and grow as a technical leader while solving challenging system-design problems.

Employees may apply for a new role after completing 12 months of employment in their current position.
