Software Engineer, Infrastructure

<h1>Software Engineer, Infrastructure</h1> <p>New York | Full Time</p> <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.</p> <p>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.</p> <p>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> <h2>Who We Are</h2> <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> <h2>About the Role</h2> <p>You'll join Central Tech, the small team responsible for Sixfold's shared infrastructure and internal engineering tools. We are moving our products onto a modern Kubernetes and GitOps setup, simplifying older AWS and Terraform infrastructure, and improving how product teams deploy and operate their services. The core pieces are in place, but there is still plenty to build and improve.</p> <p>Product engineers own and operate their applications from prototype through production. Our job is to give them reliable infrastructure, deployment workflows, observability tooling, and guidance so they can self-service all their development needs. When the same problem comes up more than once, we look for a reusable solution.</p> <p>We do not expect you to know every part of the system on day one. You will begin with a defined area and take on more ownership as you learn. Our stack includes Terraform, Azure and AWS, Kubernetes, Helm, Argo CD, GitHub Actions, and Datadog.</p> <p>In this role, you will:</p> <ul> <li><strong>Build and operate our infrastructure.</strong> Use Terraform to provision AWS and Azure resources. Manage Kubernetes workloads, Helm charts, Argo CD configuration, GitHub Actions workflows, and the shared services that support our appli
