True Zero recognizes that those outcomes begin and end with our people, and that is what we have built a community of like-minded, driven, and passionate individuals and innovators who are aligned in a common goal of delivering top-tier services to our customers. Our culture and commitment have been recognized through numerous accolades, including being named one of the Best Places to Work in 2023 in two categories (“Prosperous and Thriving” ($5MM-$50MM in gross revenue) and “Mid-Atlantic Region” (DC, DE, MD, NC, VA, WV)), and again in 2025 as a Best Places to Work honoree. In addition, True Zero earned coveted spots on the Inc. 5000 list of fastest-growing companies in America in 2022, 2023, and 2025, a testament to our sustained growth driven by our people-first approach and unwavering dedication to excellence.\nPosition Overview\nThe Zscaler Engineer will support the design, implementation, production deployment, and operational transition of a Zscaler Private Access (ZPA) environment as part of an enterprise identity and secure access modernization initiative. The role will focus on replacing legacy VPN and site-to-site tunnel access with a scalable, Zero Trust-aligned access architecture supporting a large, distributed population of external users and organizations. The initial environment is expected to support approximately 16,600 external users across roughly 1,600 independent agencies, with the architecture designed to accommodate future expansion to the internal workforce.\nThe engineer will be responsible for translating a validated proof-of-value architecture into a secure production environment, including ZPA tenant configuration, App Connector architecture, application segmentation, access policies, Client Connector and Browser Access strategies, DNS design, identity integration, logging, migration planning, documentation, and knowledge transfer. The position will work closely with cybersecurity, identity, networking, application, helpdesk, and agency stakeholders throughout implementation and rollout.\nJob Responsibilities\nDesign and implement enterprise Zscaler Private Access (ZPA) architectures, including App Connector placement, redundancy, capacity planning, application segments, access policies, and naming standards.\nConfigure and harden the ZPA tenant using least-privilege administrative roles, appropriate administrator authentication requirements, and secure platform configuration standards. \nDevelop and implement Zscaler Client Connector configurations that can coexist with third-party agency VPN clients without disrupting access to agency-owned resources.\nDesign and support both Client Connector and ZPA Browser Access solutions, selecting the appropriate access method based on user population, application requirements, and endpoint management capabilities.\nEngineer DNS and application access configurations, including internal FQDN design, connector-side DNS resolution, application segmentation, and controls that prevent external agencies from receiving direct access to internal DNS infrastructure. \nValidate end-to-end brokered application connectivity from external endpoints through Zscaler and the enterprise data center to protected applications, including performance, latency, connectivity, and transaction testing.\nIntegrate ZPA with enterprise identity services, including SAML federation with Okta and identity/group mappings used to enforce access policies. \nConfigure Zscaler Log Streaming Service (LSS) and integrate ZPA activity and security logging with Rapid7 InsightIDR or comparable SIEM/security monitoring platforms. \nDevelop repeatable migration procedures for onboarding organizations and applications, including application publishing, identity/group mapping, legacy VPN or tunnel cutover, validation, rollback, and decommissioning activities.\nProduce detailed as-built documentation covering the production ZPA tenant, App Connectors, application segments, policies, security hardening, and supporting configurations.\nDevelop operational runbooks and troubleshooting procedures for administrators, helpdesk personnel, technical agency contacts, and other support teams.\nProvide technical guidance and knowledge transfer to internal engineering and security teams, including train-the-trainer sessions and post-deployment hypercare support.\nJob Qualifications\nDemonstrated hands-on experience designing, deploying, configuring, and supporting Zscaler Private Access (ZPA) in enterprise environments.\nStrong understanding of Zero Trust Network Access (ZTNA) concepts and replacing traditional VPN or network-level access with application-centric, identity-aware access controls.\nExperience deploying and troubleshooting Zscaler Client Connector, including environments where Client Connector must coexist with other endpoint VPN technologies.\nExperience architecting and administering ZPA App Connectors, App Connector Groups, application segments, segment groups, access policies, and Browser Access.\nStrong knowledge of enterprise networking concepts, including DNS, routing, firewall rules, TCP/IP, application connectivity, proxy technologies, VPNs, and data center connectivity.\nExperience with enterprise identity federation and access management technologies, preferably Okta, SAML, MFA, identity groups, and identity-based access policies.\nExperience integrating Zscaler logging and telemetry with SIEM or security analytics platforms; experience with Zscaler LSS and Rapid7 InsightIDR is highly desirable.\nAbility to perform end-to-end troubleshooting across endpoints, Zscaler services, App Connectors, enterprise networks, identity systems, and protected applications.\nExperience designing highly available and scalable ZPA environments, including connector sizing, redundancy, bandwidth planning, and capacity planning for large user populations. The source specifically requires the architecture to accommodate the initial external population as well as subsequent workforce growth. \nExperience developing migration plans and executing phased or wave-based migrations involving multiple independent organizations or business units.\nStrong documentation skills with experience producing solution designs, as-built documentation, administrator runbooks, deployment guides, troubleshooting procedures, and end-user documentation.\nAbility to communicate technical concepts to audiences with varying levels of expertise, including engineers, cybersecurity teams, support personnel, business stakeholders, and nontechnical external administrators.\nExperience conducting technical knowledge-transfer sessions and transitioning newly implemented platforms to operational support teams.\nAbility to coordinate activities across parallel identity, networking, security, application, and third-party vendor workstreams.\nPreferred Qualifications:\nZscaler certifications such as Zscaler Certified Engineer/Administrator in ZPA or Zero Trust Access\nApplicable networking or cybersecurity certifications, and prior experience implementing Zscaler within government, public safety, criminal justice, or other highly regulated environments would be beneficial.","description_format":"text","description_chars":7357,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
