Staff Security Engineer

What You Will Do Daily:

• Security Strategy: Support the development of strategic security goals and maintain their alignment with the company mission and priorities.
• Secure by design: Closely collaborate with product engineering teams to co‑create secure, resilient solutions, bringing security considerations into the earliest stages of design.
• Secure by design: Review product architectures and cloud solutions with a critical and curious eye, ensuring security requirements are not only integrated but actively shape the final design.
• Offensive security: Drive internal and external security reviews, penetration tests, and red‑team exercises that challenge assumptions and reveal real‑world attack paths, periodically.
• Offensive security: Lead the selection, coordination, and oversight of external pen testing services and security certifications, transforming their findings into meaningful improvements.
• Projects and initiatives: Drive high‑impact security initiatives from the strategic security plan — from evaluating new approaches to rolling out cutting‑edge tools and capabilities across the organization.
• Customer trust: Investigate and manage customer security concerns with empathy and rigor, turning challenging questions into opportunities to deepen trust.
• Resolve security issues: Dive into complex security findings in products and internal systems, investigate root causes, and guide teams to robust, sustainable remediation.
• Security incidents: Act as a security subject matter expert during security incidents, helping teams to quickly understand, contain, and learn from emerging threats.

The Experience You Will Need:

• You can demonstrate in‑depth experience with cloud architectures - primarily AWS and distributed networks, and you’re motivated to keep exploring how modern cloud patterns can both strengthen and weaken security.
• You can demonstrate deep experience with application security assessments, including reviewing code and evaluating authentication and authorization designs with a high level of curiosity and rigor.
• You can demonstrate experience assessing and securing AI, Agentic and MCPs, and you are eager to experiment, learn, and define best practices in this fast‑moving space.
• You can demonstrate experience in penetration testing, red‑team engagements, and bug bounty programs, and you enjoy thinking like an attacker to protect what matters most.
• You can demonstrate experience with vulnerability investigation and management, from triage and prioritization to driving remediation and learning across teams.
• You can demonstrate experience with threat modeling using frameworks like STRIDE, and you naturally use these techniques to spark better design discussions.
• You can demonstrate hands-on experience with coding, “vibe‑coding,” and scripting (for example, Python, Bash), and you enjoy building small tools and experiments that make security work faster and smarter.
• Familiarity with Azure, GCP, and Google Workspace is a plus and so is a desire to keep learning new platforms and ecosystems as Sonar evolves.
