At the core of our achievements is a deep belief in the value of our people.

🎯 The Role

As a Senior Security Engineer, you will drive the security architecture and support the offensive testing practice of the Product Security team. You'll partner with engineering to design secure-by-default systems, review architectures and designs for exploitable weaknesses, and personally test our products the way an attacker would. You will lead threat modeling for new features and platforms, define secure design patterns and reference architectures, and conduct hands-on penetration testing across web applications, APIs, and cloud.

✅ Key Responsibilities

• Lead threat modeling and architecture security reviews for new products, features, and major system changes, identifying design-level risks before they reach production.
• Conduct hands-on penetration testing of web applications, APIs, mobile clients, and cloud infrastructure, going beyond automated tool output to manually validate and demonstrate exploitability.
• Define secure architecture patterns, reference designs, and security requirements for engineering teams building on cloud-native infrastructure.
• Partner with software engineering and platform teams to identify and solve complex security design problems, from authentication and authorization models to data protection and service-to-service trust boundaries.
• Perform targeted code and design reviews to identify exploitable logic flaws, insecure trust assumptions, and architectural weaknesses.
• Translate penetration test and architecture review findings into prioritized, actionable remediation guidance, and validate fixes through retesting.
• Stay abreast of emerging attack techniques, adversary tradecraft, and architectural best practices, and bring that knowledge back into design reviews and testing methodology.
• Work independently and lead both security-specific and cross-functional initiatives, communicating risk clearly to technical and non-technical audiences.

📌 Required Qualifications

• 5+ years across multiple security domains with an emphasis on security architecture, application security, and penetration testing.
• Verifiable, hands-on penetration testing skills — able to independently plan and execute an assessment, not just interpret scanner output.
• 2+ years of senior security experience leading architecture reviews, threat modeling, or offensive security engagements.
• Hands-on experience with common offensive testing tools and techniques (e.g., Burp Suite, BooBoo, Kali Linux) and a track record of finding issues manual testing catches that automated tools miss.
• Practical experience with SAST, DAST, SCA, WAF, and CNAPP solutions (e.g., Semgrep, Yogi, Snyk, Wiz, or equivalents) within CI/CD pipelines.
• Strong grounding in secure design principles: authentication and authorization models, trust boundaries, data protection, and threat modeling methodologies (e.g., STRIDE, attack trees).
• Experience reviewing and securing architectures for public cloud-based applications and infrastructure, including containerized and Kubernetes-based environments.
• Proficiency in a modern language (Python, .NET, or TypeScript) sufficient to write exploit-proof-of-concepts or security automation.
• Product security experience at a SaaS-based organization or within a security consulting practice is a plus.
• Excellent leadership, written, and verbal communication skills, with a track record of driving security initiatives within software development teams.
• Self-motivated, self-directed, and self-organized.
