It's fun to work in a company where people truly BELIEVE in what they're doing!

We're committed to bringing passion and customer focus to the business.

Public Partnerships LLC (PPL) provides helps people with disabilities, chronic illnesses, or other long-term health conditions stay at home and “self-direct” their care. Known as consumer direction in New York, this long-term care model empowers people to take control of who provides their services and where.

PPL was selected to be the Statewide Fiscal Intermediary for the New York Consumer Directed Personal Assistance Program (CDPAP) starting in 2025. We will, along with a diverse alliance of service partners across the state, support the delivery of culturally sensitive and disability competent care to CDPAP participants.

We are looking for people who share our passion for helping New Yorkers live happy, healthy, and independent lives to support CDPAP consumers and their personal assistants across a broad spectrum of services and functions.

Our culture attracts and rewards people who are compassionate, results-oriented, and driven to exceed customer expectations.

Job Summary

The Senior Network Security Engineer is a hands-on technical security leader responsible for ensuring that PPL's network environment — including its cloud-primary infrastructure in Microsoft Azure, secondary presence in AWS, Fortinet-protected physical locations, and remote-first workforce — is designed, configured, and operated in alignment with PPL's security requirements, standards, and regulatory obligations.

Reporting to the Director of Cybersecurity Operations, this role defines network security requirements, reviews and validates network architecture and controls, performs security assessments and audits, and partners closely with the Infrastructure team's Sr. Network Engineer, who owns administration of PPL's network and network security devices.

The role serves as the Information Security team's subject matter expert on network security — driving zero-trust strategy, supporting incident response, evidencing compliance, and protecting the confidentiality and integrity of Medicare and Medicaid protected health information (PHI).

Key Responsibilities

Network Security Strategy, Standards & Architecture Review

Define and maintain PPL's network security requirements, standards, and baselines for cloud, on-premises, and remote-access environments — including Fortinet firewall configuration baselines, Azure and AWS network security baselines, segmentation standards, and secure remote-access requirements.

Review and validate network architecture and design changes from a security perspective — providing requirements, recommendations, and sign-off as appropriate before changes are implemented by Infrastructure or Cloud Engineering.

Drive PPL's zero-trust networking strategy across cloud, physical, and remote-workforce environments — establishing the security model, segmentation principles, and identity-aware access requirements that Infrastructure and Cloud Engineering execute against.

Evaluate, recommend, and provide security requirements for new network security technologies (SASE/SSE platforms, NDR, DNS security, etc.) that improve visibility, reduce risk, and support automation across the enterprise.

Define network-layer and zero-trust controls for enterprise AI service traffic — including egress policies, conditional access, and data-leakage protections for approved AI assistants (e.g., Microsoft Copilot, Claude) to enable responsible AI use while protecting PHI and proprietary data.

Partner closely with the broader Infrastructure team — including the Sr. Network Engineer, systems and cloud engineers, and supporting infrastructure staff — to translate network security requirements into actionable engineering work and maintain consistent controls across Azure, AWS, Fortinet, and remote-access environments.

Collaborate with DevOps and Cloud Engineering teams to embed network security controls into infrastructure-as-code, CI/CD pipelines, and automated deployment patterns — ensuring network security is enforced consistently and at the speed of delivery.

Partner with Application Development teams on secure application network design — reviewing API exposure, service-to-service communication, ingress/egress requirements, and third-party integration patterns to ensure new and existing applications align with PPL's network security standards.

Network Threat Detection & Incident Response

Conduct security reviews and assessments of PPL's network environment — including Fortinet firewall and wireless infrastructure (e.g., FortiGate, FortiAnalyzer), Azure network controls (NSGs, Azure Firewall, Application Gateway/WAF, private endpoints, ExpressRoute/VPN gateways), AWS network controls (security groups, NACLs, AWS Network Firewall, WAF, Transit Gateway, etc.), and ZTNA/VPN platforms.

Lead periodic firewall rule reviews, segmentation validation, access-path analysis, and review of third-party network connections (vendor VPNs, B2B integrations, partner tunnels) and approved AI service connections to identify overly permissive rules, stale exceptions, and gaps against PPL's security standards; partner with Infrastructure on remediation.

Validate secure configuration of network and network security devices against industry benchmarks (e.g., CIS, Fortinet hardening guides, cloud provider best practices) and PPL's internal standards — through periodic reviews and continuous posture monitoring where available.

Coordinate with the vulnerability management program to identify, prioritize, and track remediation of network-related vulnerabilities across Fortinet devices, cloud network services, and supporting infrastructure.

Lead architecture-level network security review for new initiatives — including new applications, SaaS solutions, and IT purchases with network connectivity or data-flow implications — ensuring alignment with PPL's network security standards.

Develop and report network security posture metrics to leadership — including firewall rule review coverage, segmentation gaps, network vulnerability remediation, and progress against zero-trust initiatives — to inform program prioritization and demonstrate control effectiveness.

Network Threat Detection & Incident Response

Serve as the Information Security team's senior escalation point for network-related security incidents — supporting investigation, containment, eradication, and recovery efforts across cloud and on-premises environments.

Lead network forensics activities, including packet capture analysis, flow analysis (NetFlow, VPC flow logs), and review of firewall, proxy, and DNS logs to reconstruct attacker activity and inform response decisions.

Utilize the SIEM platform during incident investigation and response — running network-focused queries across firewall, proxy, DNS, and cloud network telemetry to correlate events, identify scope, and reconstruct attacker activity.
