Security Engineer, Product Security team

Job description

We are on the lookout for a Security Engineer ll to join our Product Security team . In this role, you will work directly alongside senior engineers and product development teams to ensure our web, mobile, and backend applications are built securely from the ground up. You will champion a "Secure by

Design" approach, helping us shift security left into the early stages of the development lifecycle. From assisting with application threat models and triaging vulnerability reports to configuring CI/CD security tooling and helping developers write secure code, you will play a key operational role in keeping our global delivery platform safe

Application Security Testing & Remediation: Conduct security assessments, review code, and assist product teams in remediating application-layer vulnerabilities (such as the OWASP Top 10) across our web and mobile apps.

Bug Bounty & Vulnerability Triage

Help manage our Bug Bounty and Vulnerability Disclosure Programs , systematically triaging, validating, and reproducing reported flaws before routing them to the right engineering teams.

DevSecOps Integration

Assist in implementing and maintaining automated security testing tools (SAST, DAST, SCA) directly within our CI/CD pipelines to catch vulnerabilities automatically.

Participate in Threat Modeling

Partner with senior security engineers to facilitate threat modeling sessions and architectural reviews for new features and microservices using frameworks like STRIDE.

Support AI & Security Automation

Support team initiatives in leveraging modern security automation and AI-driven tools to optimize vulnerability triage, code analysis, and daily security workflows.

Track Vulnerability SLAs

Help track remediation progress against key metrics like Mean Time to Remediate (MTTR) and SLA Adherence % , working directly with developers to ensure timely fixes.

Developer Enablement

Serve as a helpful partner for software engineers, providing guidance on secure coding standards, best practices, and secure library usage.

Qualifications

What you need to be successful

Application Security Fundamentals: Solid foundational knowledge of web and mobile application security principles, common vulnerability types (OWASP Top 10), and basic web/API security architectures.

Hands-On Coding Ability

Ability to read and understand code in at least one modern programming language (e.g., Java, Python, Go, or TypeScript ) to help identify and fix security flaws.

Vulnerability Triage & Validation

Experience reproducing application vulnerabilities (e.g., XSS, SQLi, IDOR, authentication bypasses) and using tools like Burp Suite or OWASP ZAP.

DevSecOps & CI/CD Awareness

Basic understanding of modern CI/CD systems (e.g., GitHub Actions, GitLab CI) and how automated security scanners (SAST/SCA) integrate into developer workflows.

Cloud & Container Baselines

Exposure to basic cloud computing principles (AWS, GCP, or Azure) and container concepts ( Docker, Kubernetes ).

AI & Automation Curiosity

Eagerness to learn and utilize AI-driven tools (such as LLM coding assistants) to automate security scripts, triage tasks, and security analysis.

Pragmatic Communication

Strong collaborative skills and an empathetic approach to partnering with software engineers to solve security issues without slowing them down.

Nice to have

Experience participating in Bug Bounty programs (as a reporter or triager) or CTF (Capture The Flag) competitions. Familiarity with authentication/authorization standards like OAuth 2.0, OIDC, or SAML. Industry certifications focusing on foundational security skills (e.g., Security+, eJPT, or GWAPT).
