NetworkSecuritySoftwareEngineer

## Description Basic Function Lumin Digital is standing up a dedicated Network Security function within its Risk Engineering group to protect a growing product suite that handles sensitive financial data across multiple product lines. This role exists because the landscape has shifted: in a cloud-native, infrastructure-as-code environment, network security is no longer about managing router ACLs—it is about designing identity-aware policy enforcement, automating end-to-end change management, and building real-time visibility into network activity across both workforce and hosted contexts. As the Network Security Software Engineer, you will be a domain authority who breaks network security out of the existing Security Engineering and SOC functions, building the specialization from the ground up. You will architect and deliver automated, lights-off pipelines—using agentic development practices and tools like Claude Code—that turn around security changes faster, go deeper than port and protocol in our defense-in-depth story, and extend coverage to the agents our teams create, not just the people who create them. We are looking for a senior practitioner who will teach us what great network security looks like in a modern, highly-automated fintech environment—not someone who needs to be taught. Essential Functions and Responsibilities: Own the architecture, implementation, and continuous improvement of Lumin’s network security program across cloud, SD-WAN, and ZTNA layers—designing identity-aware, policy-driven controls that secure both human and machine (agent) identities. Design and deliver fully automated, end-to-end network security change management pipelines that eliminate manual toil, accelerate change velocity, and maintain audit-ready evidence at every step. Build and operate real-time network telemetry, monitoring, and alerting systems that provide deep visibility into network activity — integrating threat intelligence feeds, cloud connectivity data, and asset
