Senior Manager, Security Engineering and Architecture

CarGurus • Boston, MA

3h • Hybrid

About The Position

We are seeking a Senior Manager of Security Engineering and Architecture to lead our Application and Cloud Security programs. Reporting to the Director Information Security, you will lead a team of high-caliber engineers responsible for the security of our AWS environment, data intelligence pipeline, and internal software products.
This is a "builder-first" leadership role. You will bridge the gap between abstract security architecture and concrete software development, ensuring that our products—especially our emerging AI/ML features—are secure by design and our cloud infrastructure is resilient by default.

Requirements

• 10+ years in Information Security or Software Engineering, with at least 5 years of hands-on software development experience (e.g., Python, Go, Java).
• 5+ years in a formal leadership role, with a proven track record of managing senior and staff-level security engineers.
• Deep familiarity with the MITRE ATLAS™ framework. You understand how to defend "Agentic" AI systems against Prompt Injection and Excessive Autonomy.
• Professional-level mastery of AWS security architecture (SCPs, VPC design, GuardDuty, and Serverless security).
• Significant experience building and scaling Application Security programs, including threat modeling and API security.
• The ability to communicate clear, data-backed priorities to executive leadership while remaining a Catalyst for Impact who steps up to take ownership alongside the team.
• Expertise in Terraform, container security (K8s/EKS), and modern GRC integration (e.g., SAFE Security).

Responsibilities

• Lead the strategic design of secure AI lifecycles. You will implement technical guardrails for the "Data-to-Inference" pipeline, protecting against Data Poisoning, Adversarial Evasion, and Model Extraction attacks.
• Serve as the primary technical authority on our AI Governance Committee. You will define "Secure-by-Design" standards for LLM integration, ensuring alignment with ISO 42001 and the OWASP Top 10 for LLM Applications.
• Champion the implementation of technical controls within the CI/CD pipeline. You will ensure that security testing (SAST/DAST/SCA) and ML-BOM (Machine Learning Bill of Materials) tracking are frictionless parts of our agile development lifecycle.
• Oversee the design of secure architectures in AWS, ensuring that identity (IAM), data protection, and network security are baked into our multi-account environment using Terraform and Policy-as-Code.
• Champion the security architecture for our Snowflake data platform, implementing advanced RBAC models and encryption standards that satisfy global privacy frameworks (GDPR/CPRA).
• Encourage your team to experiment with novel security tools and "pave the road" for developers to move fast without compromising safety.
• Proactively manage the growth of your engineering team. You will create experiential opportunities for engineers to move between application security, cloud infra, and adversarial AI research.
• Work alongside Product and Engineering leaders to reconcile security requirements with business velocity, ensuring we deliver secure results together.

Benefits

• We reward our Gurus’ curiosity and passion with best-in-class benefits and compensation, including equity for all employees, both when they start and as they continue to grow with us.
• Our career development and corporate giving programs, as well as our employee resource groups (ERGs) and communities, help people build connections while making an impact in personally meaningful ways.
• A flexible hybrid model and robust time off policies encourage work-life balance and individual well-being.
• Thoughtful perks like daily free lunch, a new car discount, meditation and fitness apps, commuting cost coverage, and more help our people create space for what matters most in their personal and professional lives.
