About the role

<h2>Software Engineer, Product</h2> <p>Insurance underwriting runs on human judgment, manual workflows, and knowledge locked in someone's head. It breaks when that person leaves and doesn't scale when the book doubles.&nbsp;Sixfold is building AI agents that understand risk the way a 20-year veteran underwriter does. Not summaries or flags, but systems that make real decisions on billions in premium for some of the world's largest carriers. AI is the product and the workflow.&nbsp;In this role, you will build and run the cloud infrastructure, Kubernetes environments, deployment tooling, and observability systems that enable Sixfold's engineers to develop, release, and operate our products.</p> <h3>Who We Are</h3> <p>🏔 Product: Sixfold is the AI brain for underwriting. Our platform handles submissions at scale, assessing risk against appetite, surfacing cited insights, and deploying AI agents to handle research, referrals, and triage so underwriters can focus on building profitable portfolios.</p> <p>💪 Team: A focused team of insurance operators, AI researchers, and engineers who love hard problems. We're pushing the boundaries of AI adoption across every function, from how we build, to how we sell and to how we support customers. We ship fast and stay close.</p> <p>📈 Traction: Processing billions in premium for some of the world's largest carriers. We know AI. We know underwriting. We're building what comes next.</p> <h3><strong>About the Role</strong></h3> <p>As a software engineer at Sixfold, you will:</p> <ul> <li><strong>Build and deliver quality software.</strong> You will write, test, and deploy code across the full application stack, primarily using TypeScript. You will build new product capabilities in our TypeScript stack and contribute to established Ruby and Python services when needed. You’ll work on team-level projects, applying engineering best practices and contributing to the team’s technical decision-making.</li> <li><strong>Develop AI engineering expertise.</strong> You'll have opportunities to learn and apply machine learning principles, work with large language models, and integrate AI capabilities into our products. You'll collaborate with our AI engineers to understand best practices for prompt engineering, model evaluation, and responsible AI development.</li> <li><strong>Collaborate with cross-functional partners.</strong> Our teams include product managers, designers, and engineers working together to accomplish shared goals. You will collaborate with these partners, beginning with problem discovery through solution design and delivery. We work in two-week cycles and release to production at least once a week.</li> <li><strong>Own your software through its entire lifecycle.</str
