Lead Software Engineer - Proxy SSE Network Security

Salary: £100,000 - 100,000 per year

Requirements:

• We require 5+ years in network security / SASE / SSE / identity security / security engineering, or equivalent depth.
• We require a strong understanding of Zero Trust principles, policy-based access, segmentation, and secure egress.
• We require hands-on experience with proxy/gateway architectures, including forward proxy, reverse proxy, and IAP patterns, as well as secure internet access controls.
• We require deep knowledge of SAML, OIDC, OAuth 2.0 concepts, and JWT, including signing, verification, JWKs, rotation, scopes/claims, and replay protection.
• We require demonstrated experience leading effective use of approved AI-assisted software development tools, with clear expectations for validating AI outputs for correctness, performance, and security.
• We require strong understanding of responsible AI use in engineering workflows, including data sensitivity, secure handling of inputs and outputs, and resiliency and security expectations.
• We require demonstrated experience delivering regional execution ownership in the US or North America for infrastructure and/or security platforms, including prioritization, cross-team coordination, and accountability for operational and delivery outcomes.
• We require experience supervising engineers and delivering cross-team remediation, modernization, and platform programs with clear scope, dependency management, delivery milestones, and measurable outcomes.
• We require strong knowledge of network and perimeter security architecture and controls, including segmentation, routing and policy considerations, encryption and access control patterns, and defense-in-depth design principles.
• We require experience designing, delivering, or operating proxy and/or SSE capabilities at enterprise scale, and translating security requirements into deployable patterns and operational guardrails.
• We require strong experience translating security requirements into deployable edge and perimeter-adjacent connectivity patterns, including Cisco and Arista environments, aligned to operational and control requirements.
• We require working knowledge of interconnect and colocation connectivity models, including Equinix Fabric, and cloud adjacency patterns including AWS Direct Connect and AWS PrivateLink.
• Preferred: experience integrating US delivery requirements and stakeholder needs into global standards, reference architectures, and governance models while maintaining a consistent global risk posture.
• Preferred: experience leading AI-threat-informed remediation programs, including adapting standards and engineering patterns for high-velocity reconnaissance, rapid technique iteration, and automation-driven exploitation attempts.
• Preferred: experience building enterprise-scale governance programs for security engineering, including controls-by-design, exception frameworks, audit-ready traceability, and measurable risk reduction reporting.
• Preferred: experience with large-scale operations for externally facing or security enforcement services, including observability strategy, resilience testing, incident response alignment, and reduction of repeat incidents and client-impacting events.
• Preferred: experience designing and operating hybrid edge architectures and cloud interconnect patterns across multiple cloud providers.
• Preferred: security certifications such as CISSP, CCSP, or comparable credentials.

Responsibilities:

• We execute creative network security software solutions, including design, development, and technical troubleshooting.
• We develop secure, high-quality production code and review and debug code written by others.
• We architect and implement Zero Trust Network Access patterns for user-to-app and user-to-internet access.
• We build and operate an Identity-Aware Proxy and policy enforcement point for web and application access.
• We implement or integrate Secure Gateway / Secure Web Gateway capabilities, including URL filtering, TLS inspection where approved, malware protection, sandboxing, egress controls, and DNS security.
• We drive team adoption of enterprise-authorized AI-assisted engineering practices to improve code quality, delivery speed, and operational outcomes.
• We apply knowledge of Software Development Life Cycle tools, including enterprise-authorized AI-assisted development and automation capabilities, to improve automation value.
• We identify opportunities to eliminate or automate remediation of recurring issues to improve operational stability.
• We own the US perimeter, proxy, and SSE/SASE engineering roadmap and execution, including intake, prioritization, dependency management, delivery governance, and stakeholder alignment.
• We define and operationalize standards, reference architectures, and reusable engineering patterns for perimeter and egress controls.
• We provide engineering leadership across edge and connectivity adjacencies, including Cisco and Arista edge environments, colocation and interconnect ecosystems, and cloud adjacency patterns such as AWS Direct Connect and AWS PrivateLink.
• We establish and run governance mechanisms that accelerate remediation while preserving strong controls, including backlog governance, exception handling, risk acceptance and closure workflows, traceability, auditability, and reporting.
• We drive operational excellence at scale for perimeter, proxy, and SSE services in the US, including incident, change, and problem management rigor, observability, resiliency validation, automation, client and partner impact reduction, and Technology Lifecycle Management outcomes.
