THE OPPORTUNITY We're looking for a Senior Security Engineer to run security operations at Kin. We're remote-first and fully cloud-based, with Kinfolk across more than 35 states working from company laptops and personal devices, signing into everything through SSO. That makes endpoints and identity our front line. Who has access to what, which devices are allowed to touch our data, and how fast we catch it when something goes wrong are the questions this role answers every day. This is a hands-on role, not a consultative one. You'll own our EDR/MDR stack and the detection tuning, runbooks, and automation that keep a lean team focused on real threats. You'll run endpoint security across managed laptops and BYOD, partner with IT to define the access controls and identity policies that govern our SSO environment, and lead incident response from first alert through containment. You'll also work directly in AWS, building and remediating cloud security controls. And you'll be the person Kinfolk come to with security questions, answering fast enough that people ask rather than guess. Customers trust us with their claims, their property details, and their financial information. Protecting that is the work. YOUR RESPONSIBILITIES - Own and tune our EDR/MDR stack, building the detection policies, runbooks, and automation that keep escalations focused on real threats - Lead incident response end to end: investigation, containment, and remediation, from compromised laptops to cloud and identity incidents - Own endpoint security across managed and BYOD devices, setting device posture standards, hardening baselines, and the policies that govern what can access Kin data - Define the security requirements behind our identity program and partner with IT to implement them in SSO, shaping our RBAC model and driving an access review cadence that removes stale permissions - Build and remediate security controls across AWS infrastructure, Google Workspace, identity, and data protection - Serve as the front door for security across Kin, turning around security tickets and questions quickly enough that people bring you things early instead of working around the process - Conduct threat modeling across systems, processes, and vendor implementations, delivering risk assessments teams can act on - Instill a culture of security across the company, taking everyday opportunities to educate Kinfolk, raise awareness of real risks, and give people in every function the judgment to make safer decisions on their own Success in this role In your first 6–12 months at Kin, success is less about checking boxes and more about the impact you create. You’ll use your skills and judgment to take ownership of meaningful work, improve how we operate, and help move Kin’s mission forward. Along the way, you’ll deliver outcomes that make a real difference for both Kinfolk and the homeowners we serve. By the end of your first year, you should feel confident in your role, trusted as an owner, and proud of the progress you’ve helped make. - Detection is tuned and backed by runbooks, so the team's hours go toward investigating real threats instead of triaging noise - A clear device posture standard exists, managed devices meet it, and access reviews run with IT on a predictable cadence instead of being a scramble before an audit - Cloud vulnerabilities and misconfigurations across AWS and Google Workspace are getting fixed by your own hands, not documented and queued, and the riskiest gaps you inherited are closed WHAT YOU’LL BRING Technical - 5+ years in security operations, detection and response, or security engineering - Hands-on experience running a modern EDR program: building and tuning detection logic, writing response runbooks, and leading investigations through to containment - Endpoint security experience across managed and BYOD fleets, including device posture, hardening baselines, and MDM - Identity and access management depth: defining access control requirements, designing RBAC models, and running access reviews in an SSO environment - AWS security experience across IAM, network controls, logging, and configuration management, with a track record of remediating findings directly - Comfort working in infrastructure-as-code en
