📋 Description

• Build, lead, and mentor a team of senior Network Security Software Engineers — owning the hiring process, setting role expectations, and onboarding engineers into a newly established function. • Define and continuously mature the network security program — establishing policies, standards, runbooks, and roadmaps across cloud infrastructure, corporate IT, and third-party connectivity; own network segmentation strategy across product and environment boundaries. • Serve as the primary escalation point for architectural decisions and cross-functional scope disputes — maintaining clear lines of authority as the function establishes itself within the broader engineering organization. • Partner with the Director of Risk Engineering to communicate program status, risk posture, and investment needs; contribute to security strategy reporting to senior leadership. • Own Lumin's network security architecture strategy and change management model across cloud, SD-WAN, and ZTNA layers — designing identity-aware, policy-driven controls that secure both human and machine (agent) identities, and setting the standard for fully automated, audit-ready change delivery. • Serve as the program-level authority for the team's network security tooling and automation initiatives — writing, reviewing, and iterating on engineering specifications that drive AI-assisted coding workflows; validating software outputs for correctness and security soundness, applying hands-on expertise that engineering tools alone cannot provide.

🎯 Requirements

• Bachelor’s degree in Computer Science, Information Security, Network Engineering, or a related technical field, or equivalent combination of education and experience. • 7+ years of progressive experience in network security, with at least 2 years in a lead or management capacity, in a cloud-native or hybrid environment. • Demonstrated track record of building or maturing a network security program — including policy development, tooling evaluation, team building, and cross-functional stakeholder management. • Direct experience with network security platforms such as Cloudflare (WAF, Workers, Rulesets, Terraform provider), Zscaler (ZIA, ZPA), Palo Alto, or equivalent tier-one solutions. • Experience in fintech, banking, payments, or other regulated financial services environments (PCI-DSS, SOC 2, ISO 27001) strongly preferred. • Experience with infrastructure-as-code (Terraform, CloudFormation) and CI/CD-driven infrastructure provisioning. • Experience with leading teams that leverage agentic coding tools and workflows (Claude Code, Cursor, or equivalent)—or demonstrated eagerness and aptitude to adopt them as a primary development methodology.
