Application Security Engineer

About the role:

We are looking for a technically strong Senior Application Security practitioner ready to take on real ownership. You will work directly with the Head of AppSec, contributing to the Secure Design practice and helping drive shift-left security across the organization.

What You'll Do

• Help build and mature the Secure Design and Threat Modeling program by defining methodology, review standards, and sign-off criteria across the organization
• Drive shift-left security initiatives, embedding security earlier in the development lifecycle through design reviews, developer enablement, and security gating in CI/CD
• Own API security as a discipline
• Support offensive security initiatives
• Build and maintain security automation in Python, tooling that scales AppSec capacity
• Work directly with developers on SAST and SCA remediation, scan optimization, and reducing friction in the security feedback loop
• Contribute to AI-assisted security pipelines; define escalation paths, SLAs, and accountability structures for vulnerability management

What We're Looking For

• Hands-on experience across secure design, threat modeling, API security, and offensive security
• Offensive security capability with penetration testing experience and solid understanding of real-world attack and API exploitation patterns
• Deep familiarity with OWASP Top 10 in practice
• API security depth, experience assessing REST and GraphQL APIs
• Python proficiency, comfortable building automation tools that others will depend on
• Experience in shift-left programs: security in CI/CD, developer enablement, design review processes
• Understanding of web application and API security
• Comfortable reading code across languages and engaging with engineering teams at technical depth
• Familiarity with cloud-native environments and attack surface management
• Demonstrated ability to influence across engineering and product and operate at architecture level
• Relevant certifications are a plus: OSCP, OSWE, GWEB, CSSLP, CISSP, CEH
• Exposure to AI-assisted security tooling or LLM security is a differentiator
• Experience as a developer and fluency in Ruby, Python, and Scala are a plus

We believe the best ideas and innovation happen when we are together. Employees in this role will work in the office four days, with the flexibility to work remotely one day (Friday).
