Senior Software Engineer, Underwriting

About the role

The Senior Software Engineer on the Underwriting team designs and builds backend services and systems that power Coalition's cyber insurance underwriting decisions. They integrate security, insurance, and proprietary data to apply business rules, statistical models, and machine learning in assessing and monitoring risk. This role is highly cross-functional, partnering closely with underwriters, data science, and other engineering teams to scale and automate Coalition's underwriting and core decisioning workflows. The position demands strong ownership of the full lifecycle of complex features from conception through production. You will translate nuanced underwriting requirements into resilient technical implementations while maintaining strict standards for reliability and performance. Collaboration with stakeholders across the organization will drive the prioritization and delivery of high-impact capabilities. This role is central to enabling scalable risk assessment and automation across the underwriting platform.
