About the role

Key responsibilities & impact

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

What you’ll need

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.
