Manager, Security Engineering

The Trade Desk operates one of the largest and most performant programmatic advertising platforms in the world. The security of our customers’ data, the trust of our partners, and the velocity of our engineering teams all hinge on the strength of our application and platform security programs. As our security posture continues to mature, we are investing in the leadership required to drive that maturity forward. 

We are looking for a Manager, Security Engineering to join our Cybersecurity Department. This person will lead a combined team of Application Security and Platform Security engineers, with end-to-end ownership of how TTD secures both the code we ship and the infrastructure we run it on. Reporting within the Cybersecurity organization, this leader will contribute to the strategy, roadmap, and execution of TTD’s Security Engineering function — including the KPIs, maturity model, and executive-level reporting that demonstrate measurable improvement in our overall security posture over time. 

The right candidate brings deep application and platform security expertise, a track record of building and developing high-performing teams, a strong bias to action, and the ability to translate technical risk into business outcomes for engineering leaders, product leaders, and executives.  

Beyond the technical and program experience, we are looking for a leader with the human qualities that make a security team effective. You lead with integrity, communicate clearly, and bring empathy to your team, the engineers we partner with, and the customers whose trust we hold. You are deeply curious about how systems work and how they break, and you pair that curiosity with a strong bias to action and ownership of outcomes. You stay calm under pressure, and you approach feedback — both giving and receiving it — with humility and a willingness to grow. Security is a team sport, and the right leader sets that tone every day. 

What You'll Do:

• Lead, grow, mentor, and develop a combined team of Application Security and Platform Security engineers; drive performance, growth, and retention across the function. 

• Own and evolve The Trade Desk’s Security Engineering strategy, roadmap, and maturity model across both application and platform domains; define and report KPIs that demonstrate measurable improvement in security posture to senior leadership. 

• Ensure consistency and alignment across application and platform security controls — driving unified standards, shared tooling, and integrated posture outcomes for the enterprise. 

• Drive shift-left integration of security into the SDLC in partnership with Engineering and Product — including threat modeling, secure design reviews, and the rollout and tuning of SAST, DAST, and SCA tooling. 

• Mature TTD’s posture management capabilities across cloud and infrastructure — including CSPM, Infrastructure-as-Code scanning, hardening baselines, and configuration management. 

• Mature TTD’s vulnerability management and remediation orchestration practices — including triage workflows, risk-based prioritization, SLA tracking, and integration with engineering workflows. 

• Represent the Security Engineering function across the broader organization — Engineering, Product, Compliance, Security Response, and executive leadership — and influence roadmap decisions, resource allocation, and security investment priorities. 

 Who you are: 

• Bachelors degree in related field or equivalent years of experienec required.  MS degree preferred.
• 7+ years of experience in Information Security or Cybersecurity, with hands-on depth in Application Security and/or Platform/Cloud Security. 

• 2+ years of experience leading and developing security engineering teams, including hiring, mentoring, performance management, and roadmap ownership. 

• Experience driving a measurable security maturity program — defining KPIs, reporting to leadership, and demonstrating posture improvement over time. 

• Experience building programs that apply industry-standard security best practices and reconcile them against business and engineering needs. 

• Experience managing a security assessment program — including architecture reviews, secure design reviews, threat models, and code/configuration reviews across many product teams. 

• Experience building security visibility and engagement programs (e.g., Security Champions, security awareness, training) that scale culture and coverage across the organization. 

• Working knowledge of cloud security, Cloud Security Posture Management (CSPM), and Infrastructure-as-Code scanning across one or more major cloud platforms (AWS, GCP, or Azure). 

• Strong understanding of secure software development and deployment practices, including common application security risks and mitigations (e.g., OWASP, CWE). 

• Familiarity with common Information Security frameworks and standards such as MITRE ATT&CK, NIST, and ISO 27001/27002. 

• Excellent written and verbal communication skills — able to translate technical risk into business outcomes for executive audiences and to communicate, influence, and manage expectations directly with engineering teams. 

• Certifications such as CISSP, CSSLP, GWAPT, OSWE, or cloud security certifications (AWS, GCP, or Azure) are a plus. 

• Knowledge of PII, PHI, financial data regulations, data residency requirements, and international regulatory aspects pertaining to sensitive information is a plus. 

• Experience in ad tech, large-scale SaaS, or other high-throughput consumer/enterprise platforms is a plus.
