About Us Abacus Insights is transforming how data and AI work for health plans. Our mission is simple: make healthcare data usable, so the people responsible for care and cost decisions can act faster, with confidence. As the AI and Data Platform for Payer Intelligence, we help health plans break down data silos to create a single, trusted data foundation. That foundation powers better decisions—so plans can improve outcomes, reduce waste, and deliver better experiences for members and providers alike. Backed by $100M from top investors, we're tackling big challenges in an industry that's ready for change. Our platform enables GenAI use cases by delivering clean, connected, and reliable healthcare data to support automation, prioritization, and decision workflows—and it's why we are leading the way. Our innovation begins with people. We are bold, curious, and collaborative—because the best ideas come from working together. We embrace the thoughtful use of AI and automation to drive innovation and efficiency, and we look for individuals who are curious and adaptable—those excited to leverage emerging technologies to enhance how we work—while keeping human insight, connection, and our clients at the center of every decision. Ready to make an impact? Join us and let's build the future together. About the Role AI is the engine behind where Abacus is headed next, and this role works directly alongside the engineers building that future. We are looking for a Senior AI Security Engineer who is deeply technical and passionate about designing, building, and securing AI-enabled applications that support real customers in regulated healthcare environments. This is not a traditional security review or compliance role. You will partner with Senior AI Engineers, data quality engineers, platform engineers, DevOps, product owners, and customer delivery teams throughout the development lifecycle. You will help design architectures, contribute code and automation, establish reusable security controls, review implementations, and support secure deployment and operation of Abacus Agents, MCP-based solutions, SQL and RAG agents and tools, and other AI-enabled products. You will also help enable citizen application development by creating secure paved roads for business-built and AI-assisted applications. The emphasis is on practical engineering: helping teams move quickly while ensuring identity, data protection, authorization, observability, privacy, and compliance are built into each solution from the start. You will also help build the secure foundations for enterprise knowledge services, including graph-backed knowledge stores and MCP-served retrieval tools that give people and AI agents governed, auditable access to company knowledge. This work spans cloud infrastructure, network, identity, and data layers, so that these services are private by default and secure by design.
