Job Description

Position Summary

As a key member of our Internal Product Security Engineering team, you will lead penetration-testing engagements for high-scale web applications and APIs, validating security controls and uncovering exploitable weaknesses. In parallel, you will conduct structured threat-modeling workshops and security-design reviews for new features and services, managing each engagement from scoping to remediation follow-up in close partnership with engineering and cross-functional stakeholders. The insights you provide will drive prompt fixes and shape the organization's long-term security roadmap.

• Threat Modeling & Security Design Review
• Facilitate formal and informal Threat Modeling using STRIDE-like frameworks or Attack-Tree sessions for new or significantly modified services.
• Produce risk artefacts, recommend mitigations, and track closure of findings.

• Scripting/automation ability in Python, Go, or similar; quick at reading unfamiliar codebases.
• Practical experience with STRIDE or comparable threat-model frameworks.
• Familiarity with cloud-native environments (microservices, Kubernetes, serverless).
• Communication: Exceptional written and verbal skills for both technical and non-technical audiences.

Preferred Qualifications

• Offensive-security certifications (OSCP, OSWE, OSWA, BSCP).
• Secure-coding experience in languages such as: Java, Node.js, C#, Python, or Rust.
• Experience in security controls for cloud platforms such as AWS, Azure, or Google Cloud.
