Role Summary

We are looking for a highly motivated Senior Application Security Engineer to join our Application Security team. This role will focus on securing modern cloud-native applications, with emphasis on API security, Infrastructure as Code (IaC), containerized workloads, and Open-Source Software (OSS) security.

The ideal candidate will work closely with engineering, platform, and product teams to embed security into the SDLC and enable secure-by-design development practices on a scale.

Key Responsibilities

Application & API Security

• Establish and mature an API security program, including tools, processes, governance, standards, and best practices
• Define secure API design guidelines aligned with OWASP API Top 10 and industry standards
• Evaluate and integrate API security tools into the SDLC and CI/CD pipelines
• Partner with engineering teams to embed secure-by-design API patterns
• Guide implementation of API authentication and authorization controls (OAuth2, OIDC, JWT, mTLS)

Infrastructure as Code (IaC) Security

• Review and assess IaC templates (Terraform, ARM, CloudFormation, etc.) for security misconfigurations
• Define and maintain secure IaC guardrails and policies
• Integrate IaC security scanning into CI/CD pipelines
• Partner with cloud and platform teams to remediate infrastructure risks early in the lifecycle

Container & Kubernetes Security

• Assess container images for vulnerabilities, misconfigurations, and insecure base images
• Review Kubernetes manifests, Helm charts, and deployment configurations
• Advice on runtime security controls, least privilege, and workload isolation
• Support adoption of container security best practices across development teams

Open-Source Software (OSS) Security

• Manage open-source risk including vulnerabilities, licensing, and supply-chain threats
• Support and tune SCA (Software Composition Analysis) tools
• Drive remediation of vulnerable dependencies and guide teams on secure OSS usage
• Contribute to OSS security governance, policies, and exception handling

Secure SDLC & Enablement

• Embed security checks into CI/CD pipelines (SAST, DAST, SCA, IaC, container scans)
• Provide actionable remediation guidance to developers
• Create security documentation, standards, and secure coding guidelines
• Deliver security awareness sessions and hands-on enablement for engineering teams

Collaboration & Reporting

• Partner with AppSec peers, PSIRT, Cloud Security, and Engineering stakeholders
• Track findings, risk acceptance, and remediation progress
• Contribute to metrics and reporting for application security posture

Required Qualifications

• 4–7 years of experience in application security, product security, or secure software engineering
• Strong understanding of web application and API security fundamentals
• Hands-on experience with cloud-native environments (AWS, Azure, or GCP)
• Practical exposure to:
  • API security testing and design reviews
  • IaC tools (Terraform, ARM, CloudFormation, etc.)
  • Containers and Kubernetes
  • Open-source dependency management
• Familiarity with OWASP Top 10, OWASP API Top 10, CWE, CVSS
• Experience integrating security tools into CI/CD pipelines
• Ability to clearly communicate security risks and solutions to engineering teams

Preferred / Nice-to-Have Skills

• Experience with AppSec tooling such as SAST, DAST, SCA, IaC scanning, container security tools
• Knowledge of Zero Trust and cloud security architectures
• Experience with DevSecOps practices
• Exposure to AI/ML security, including risks related to:
  • AI-enabled applications and APIs
  • Model and dependency supply chain risks
  • Prompt injection, data leakage, and misuse scenarios
• Relevant certifications (e.g., CSSLP, GWAPT, CCSP, Kubernetes security certifications)
• Prior experience working with globally distributed engineering teams

Behavioral & Leadership Expectations

• Demonstrates independent execution within defined security domains
• Proactively identifies security gaps and drives improvements
• Strong collaboration and influencing skills without direct authority
• Balances security risk with business and engineering priorities
• Shows ownership, accountability, and a continuous learning mindset

What Success Looks Like in This Role

• Improved security posture of APIs, cloud infrastructure, containers, and OSS usage
• Faster and more effective vulnerability remediation by engineering teams
• Security embedded early and consistently across the SDLC
• Clear, scalable security standards adopted across product teams
