CAIS provides financial advisors with a broad selection of alternative investment strategies, including hedge funds, private equity, private credit, real estate, digital assets, and structured notes. CAIS also delivers industry-leading technology, operational efficiency, and world-class client service throughout the pre-trade, trade, and post-trade experience. CAIS serves over 2,500 wealth management firms that support more than 65,000 financial advisors who oversee approximately $8.5 trillion in end-client assets.\nApplication security sits at the center of how CAIS earns and keeps the trust of the advisors and asset managers who rely on our platform. As our lead for application security, you will own how we protect the applications and services we build and embedding security into the heart of how we design, write, and ship software.\nYou will define and drive our approach to secure development: setting threat modeling strategy, owning security architecture and secure code reviews, and designing the controls that live inside our SDLC. Just as importantly, you will use automation and AI to scale that work, turning security from a manual checkpoint into something engineers experience as fast, clear, and genuinely useful.\nWe are looking for a hands-on technical leader who is as comfortable reading production code as setting strategy. You are someone who enjoys partnering with engineers and product owners; you are eager to experiment with new technologies to raise our security bar across the stack, and you are easy to do business with. You see a growing security practice not as a constraint to enforce but as a capability to build, one that helps us ship reliable products, grow as engineers, and have some fun along the way.\nResponsibilities\nSecure Software Development & Architecture\nOwn security elements of the software development lifecycle, designing and implementing automated controls within CI/CD, including SAST, DAST, dependency and container security scanning.\nConduct security architecture and design reviews across product and platform areas, surfacing risk early and providing clear, actionable remediation paths.\nDrive CAIS's threat modeling strategy, establishing it as a repeatable practice across teams rather than a one-off exercise.\nVulnerability Management & Engineering Partnership\nTriage, validate, and prioritize findings, coordinating remediation through to resolution with clear ownership and follow-through.\nLiaise with key vendors on penetration testing, vulnerability scanning, and threat modeling, translating external findings into prioritized action.\nPartner with engineers and product owners to embed security pragmatically into design, development, and release, supporting teams without becoming a blocker.\nProvide secure coding guidance and clear documentation that helps teams understand risk and apply secure development practices independently.\nLevel up CAIS's security capability across the tech stack, experimenting with new tooling, automation, and AI-assisted workflows as the practice grows.\nRequired Experience\nExperience in application or product security teams. A software engineering background is\nAbility to read and reason about production code and hold your own with senior engineers, with working knowledge of Java/Kotlin and JavaScript/TypeScript (React).\nSolid AWS security experience, including securing cloud-native, containerized environments (e.g. EKS).\nHands-on experience with security tooling across the SDLC, such as SAST, DAST, and dependency or container scanning (specific products are not important).\nDemonstrated experience driving threat modeling and leading security architecture and design reviews.\nProven ability to lead engineering and security teams in adopting AI tools and automated workflows when it comes to security as part of the SDLC .\nA confident, collaborative communicator who partners effectively with engineers and product owners and explains risk clearly to both technical and non-technical audiences.\nA builder's mindset, you are energized by growing an application security practice from an early stage, eager to experiment and collaborative along the way.\nCAIS is consistently recognized as a Best Place to Work, and our culture is at the heart of our success.
