Security Engineer

We are hiring a Principal Security Engineer / DevSecOps Lead to own the security posture of our SaaS platforms, cloud environments, and AI-enabled applications. This is a senior hands-on leadership role: you will design and drive the security architecture that protects a regulated, multi-tenant investment platform, embed automated security controls into how we build and ship software, and lead red-team-informed offensive testing that measurably reduces real risk. You will partner with SRE, platform, data, and application teams — and directly with the CISO to set the enterprise standard for secure development. What you 'll do Own security architecture for our SaaS platforms, multi-cloud environments (AWS, Azure), and AI-enabled applications, including LLM- and agent-based workloads. Build and operate a modern DevSecOps program: SAST, DAST, IaC scanning, SBOM/supply-chain (Sigstore, SLSA), secrets detection, container and Kubernetes admission control, and policy-as-code (OPA/Cedar). Design and run an automated vulnerability management program that prioritizes by exploitability and business impact, drives closure SLAs, and holds engineering teams accountable through metrics. Lead application security across the SDLC: threat modeling, secure design reviews, code review at critical seams, security champions program, and paved-road guardrails engineers actually adopt. Direct red - team and adversarial testing - internal exercises, purple-team, and third-party engagements - and translate findings into durable architectural fixes, not just tickets. Harden multi-tenant isolation, identity, and data protection for a regulated buy-side platform; own the security controls that map to SOC 2, SOX, and applicable regulatory obligations. Set the security-by-design bar for AI - enabled applications : prompt-injection defense, tool/agent boundary controls, model and data provenance, retention, and abuse monitoring. Partner with IT/AI Platform, SRE, and Data Governance on identity, secrets, network segmentation, logging, and incident response; participate in on-call for security incidents. Mentor senior engineers across security and platform; represent security in executive and board-facing risk reporting when required. Required experience 10+ years in information security with deep hands-on DevSecOps and application security expertise; senior-leader scope but still writes code and shipped controls. Proven design and operation of security for SaaS platforms and cloud environments (AWS and/or Azure) at enterprise scale, including multi-tenant workloads. Strong background in automated vulnerability management and security testing — SAST/DAST/SCA, IaC/CSPM, container/K8s security, and SBOM/supply-chain tooling. Demonstrated red - team / offensive security experience: leading engagements, conducting or overseeing adversarial testing, and running purple-team exercises against real production systems. Deep secure-development expertise: threat modeling (STRIDE/attack trees), secure code review, cryptography fundamentals, identity/OAuth/OIDC, and API security. Experience securing AI - enabled applications — LLM/agent security, prompt injection, data-leakage controls, and model/tool boundary design. Strong hands-on skills in Python and/or Go; comfortable operating in Terraform, Kubernetes, and modern CI/CD. Track record leading security architecture initiatives for large-scale enterprise and multi-tenant environments, with measurable risk reduction. Nice to have Prior financial services, buy-side, or otherwise regulated (SOC 2, SOX, GLBA, NYDFS 500) environment experience. Offensive security certifications (OSCP, OSEP, OSCE, CRTO) or published research/CVEs. Experience with red-team infrastructure (C2 frameworks, EDR evasion, cloud-native attack paths) and detection-engineering collaboration. Familiarity with MCP, agent frameworks, and enterprise LLM gateways. The compensation range for this position is for a full-time employee in New York.
