Application Security Lead

We are seeking a highly skilled and hands-on Application Security Lead to take ownership of our product and infrastructure security. Reporting directly to the CISO with a dotted line to the CTO, you will act as the critical bridge between our Security and Engineering teams, driving a robust "security-first" culture.
While this role encompasses both application and infrastructure security, our primary focus is on the Application Security domain. You will lead our transition towards a mature DevSecOps organization, ensuring that security is seamlessly embedded into every phase of our SDLC without compromising delivery speed.
Key Responsibilities
Application Security & Secure Engineering:
Secure SDLC Integration: Embed security practices throughout the entire SDLC, from initial design and planning to deployment and maintenance.
Threat Modeling & Architecture: Lead threat modeling (e.g., STRIDE) and architectural reviews for high-risk features like authentication, PII, and payments.
AppSec Tooling & Automation: Integrate and manage automated security scanning (SAST, SCA, DAST) within CI/CD pipelines to ensure code integrity seamlessly.
Mobile & API Security: Enforce least-privilege models for API configurations. Lead security initiatives specifically tailored to mobile environments (iOS/Android), protecting our core mobility platform.
Offensive Security & Pentesting: Orchestrate internal red teaming and external penetration tests for web and mobile applications. Manage Vulnerability Disclosure Programs (VDP) / Bug Bounties.
Developer Empowerment & DevEx: Collaborate with developers to provide automated tools, coding guidelines, and frictionless guardrails for secure-by-design development, ensuring security acts as an enabler, not a blocker.
Incident & Vulnerability Management: Act as the technical escalation point for application security incidents, leading detection and recovery efforts, while prioritizing vulnerabilities across the product suite for timely remediation.
Cloud & Infrastructure Security:
Cloud & Network Posture: Manage cloud security posture (CSPM) across AWS/GCP and oversee broad network security measures, including WAF, Bot management, and environment segmentation.
Pipeline & Secrets Management: Secure the CI/CD infrastructure against tampering and enforce robust secret management and secure repository controls across the organization.
Resilience & Recovery: Manage disaster recovery (DR) and business continuity planning for production environments.
Governance, Culture & Compliance:
DevSecOps Strategy: Lead the strategic evolution of DevOps into a mature DevSecOps model, aligning with industry frameworks like OWASP SAMM and NIST SSDF.
Metrics & Measurement: Define and track key security metrics (e.g., MTTR, vulnerability density) to measure and improve program effectiveness.
Security Champions: Build and mentor a Security Champions program within R&D to scale security knowledge and foster a grassroots culture.
Compliance & Privacy: Ensure continuous compliance with PCI-DSS, ISO27001, and GDPR, championing privacy-by-design principles across all user data and R&D operations.
