Senior Backend Engineer, Firewall

Role overview Serve as the firewall and network security subject matter expert on a product team building capabilities for assessing and improving firewall effectiveness. You’ll translate real blue team practices into requirements, acceptance criteria, and remediation guidance that product, engineering, and AI teams can implement and evaluate. This is a domain-focused role centered on practitioner judgment and validation.

Responsibilities - Turn firewall effectiveness and tuning goals into clear, prioritized product requirements, and assess proposed behavior against real security operations workflows. - Define acceptance criteria for detection, tuning, and remediation features; validate releases against those criteria. - Advise engineering and AI research teams on firewall behavior, configuration semantics, and vendor-specific differences. - Maintain working knowledge of enterprise firewall platforms, including their management interfaces, policies, traffic handling, logs, and APIs. - Track changes to firewall platforms and guidance, and keep supported coverage and remediation standards current. - Work with attack validation teams to ensure coverage and recommendations reflect real network behavior and current adversary techniques.

Requirements - At least six years of hands-on experience in firewall engineering, network security, security operations, incident response, or threat hunting. - Production experience administering and tuning enterprise firewall platforms, such as Palo Alto, Fortinet, Cisco, or Check Point products. - Strong understanding of policy evaluation and enforcement, including rules, zones, objects, NAT, profiles, and exceptions. - Ability to explain how security tools behave in practice and turn that knowledge into measurable requirements and acceptance criteria. - Sound judgment about remediation that blocks a validated attack path while preserving legitimate traffic. - Ability to collaborate with product, engineering, and research teams as a trusted technical authority.
