What You Will Do

We’re looking for a hands-on Product Security Technical Lead to drive the design, implementation, and evolution of our security engineering program. You’ll lead a team of Security Engineers focused on hardening our SaaS and data platforms by breaking things before attackers do — identifying vulnerabilities, building secure infrastructure, and integrating protection across our CI/CD pipelines. This role demands deep technical expertise across AWS, Python, and application & cloud security, along with a hacker’s curiosity and a builder’s discipline. You’ll have complete ownership of product and cloud security from architecture to execution. You’ll lead by doing — hacking, breaking, and building resilient systems. Be part of a company where security isn’t an afterthought — it’s a product feature.

Key Responsibilities

• Own and evolve the organization’s entire application security posture, with a focus on application and cloud security across all product lines

• Perform offensive and defensive security assessments — threat modeling, code review, penetration testing, and vulnerability exploitation.
• Build and integrate automated security tooling (SAST, DAST, dependency scanning, IaC scanning) into CI/CD pipelines
• Develop security automation and internal tooling using Python, Bash, or Go.• Partner with Engineering, DevOps, and Infrastructure teams to ensure secure AWS architectures (VPC, IAM, KMS, GuardDuty, CloudTrail, WAF).
• Oversee incident response and root cause analysis for product and infrastructure-level security events.
• Define and enforce secure coding standards, and lead threat modeling sessions for critical features and services
• Continuously hunt for vulnerabilities, test assumptions, and “break things safely” to strengthen the platform

Requirements

• Bachelor's degree in computer science or another equivalent degree
• 8+ years of hands-on experience in Application, Cloud, or Product Security roles, with lead or staff-level responsibilities
• Deep expertise in AWS security architecture and service hardening
• Advanced programming and scripting ability in Python (Bash or Go a plus)
• Proven experience with offensive security: hacking, exploit analysis, or red team operations
• Strong foundation in vulnerability management, threat modeling, and incident response
• Proficient with DevSecOps tools and modern CI/CD environments
• Familiarity with container and orchestration security (Docker, Kubernetes, EKS)
• Certifications such as AWS Certified Security – Specialty, OSCP, or CISSP are a big plus
