We’re seeking our first Staff Security Engineer to lead the charge in securing our product platform—spanning web, mobile, and AI‑driven services. This role is ideal for someone who combines deep technical expertise with a proactive, automation‑first mindset. You’ll ensure our systems, data, and AI agents are protected by best‑in‑class practices and tooling, while fostering a culture of security awareness across the company. You’ll partner closely with engineering, infrastructure, DevOps, and product teams to design, implement, and maintain automated security mechanisms that scale—from continuous monitoring and vulnerability management to defending against new classes of threats emerging in the AI era (such as prompt injection and data exfiltration via LLMs). Responsibilities Design and implement automated systems to monitor, detect, and mitigate security risks across infrastructure, application, and AI layers. Lead efforts to integrate continuous security testing into CI/CD pipelines (SAST, DAST, dependency scanning, container scanning, etc.). Build and maintain automated alerting and remediation workflows for security events. Architect and implement robust authentication and authorization frameworks for end users, ensuring secure, scalable access control across web, mobile, and API surfaces (e.g., OAuth 2.0, SSO, role‑based and attribute‑based access models). Harden cloud environments (AWS, GCP) and enforce least‑privilege IAM, network segmentation, and encryption standards. Conduct architecture reviews, threat modeling, and code audits to ensure secure design across all services. Collaborate with engineering teams to define secure coding standards and best practices. Develop security frameworks and tooling to detect and prevent LLM‑specific vulnerabilities (e.g., prompt injection, data leakage, malicious model responses). Implement guardrails for AI systems, including content filtering, input validation, and output sanitization. Partner with our AI engineering team to design safe orchestration between models, APIs, and user data. Own and continuously improve our incident detection, response, and recovery processes. Collaborate on internal audits and compliance efforts. Serve as a key advisor on emerging threats, vulnerabilities, and evolving best practices. Qualifications Must Have 5+ years of experience in security engineering for production SaaS systems. Strong understanding of cloud security (AWS preferred) and modern DevSecOps practices. Experience designing or integrating automated security pipelines and observability systems. Solid understanding of web application security (OWASP Top 10, API security, encryption standards). Hands‑on experience with IaC (Terraform, Pulumi, CloudFormation) and containerized environments (Docker, Kubernetes). Experience building or securing systems involving large language models (OpenAI, Anthropic, or similar). Excellent collaboration and communication skills—able to work cross‑functionally with engineers and leadership. Nice to Have Familiarity with open‑source or proprietary LLM guardrail frameworks. Prior experience in a startup or rapid growth environment. Certifications such as OSCP, CISSP, or AWS Security Specialty. What Success Looks Like Automated systems proactively detect and mitigate vulnerabilities before they impact production. Security practices are seamlessly integrated into developer workflows. Our AI‑powered products are protected against modern attack vectors and data leakage risks. The company’s security posture becomes a competitive advantage—enabling innovation without sacrificing safety. Luxury Presence is an Equal Opportunity Employer.
