Remote NA Cybersecurity Streaming ZK Engineer Segment Documentation Knowledge Transfer

Requirements

• Demonstrated hands-on experience designing, deploying, configuring, and supporting Zscaler Private Access (ZPA) in enterprise environments. • Strong understanding of Zero Trust Network Access (ZTNA) concepts and replacing traditional VPN or network-level access with application-centric, identity-aware access controls. • Experience deploying and troubleshooting Zscaler Client Connector, including environments where Client Connector must coexist with other endpoint VPN technologies. • Experience architecting and administering ZPA App Connectors, App Connector Groups, application segments, segment groups, access policies, and Browser Access. • Strong knowledge of enterprise networking concepts, including DNS, routing, firewall rules, TCP/IP, application connectivity, proxy technologies, VPNs, and data center connectivity. • Experience with enterprise identity federation and access management technologies, preferably Okta, SAML, MFA, identity groups, and identity-based access policies. • Experience integrating Zscaler logging and telemetry with SIEM or security analytics platforms; experience with Zscaler LSS and Rapid7 InsightIDR is highly desirable. • Ability to perform end-to-end troubleshooting across endpoints, Zscaler services, App Connectors, enterprise networks, identity systems, and protected applications. • Experience 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. • Experience developing migration plans and executing phased or wave-based migrations involving multiple independent organizations or business units. • Strong documentation skills with experience producing solution designs, as-built documentation, administrator runbooks, deployment guides, troubleshooting procedures, and end-user documentation. • Ability to communicate technical concepts to audiences with varying levels of expertise, including engineers, cybersecurity teams, support personnel, business stakeholders, and nontechnical external administrators. • Experience conducting technical knowledge-transfer sessions and transitioning newly implemented platforms to operational support teams. • Ability to coordinate activities across parallel identity, networking, security, application, and third-party vendor workstreams. • Zscaler certifications such as Zscaler Certified Engineer/Administrator in ZPA or Zero Trust Access • Applicable networking or cybersecurity certifications, and prior experience implementing Zscaler within government, public safety, criminal justice, or other highly regulated environments would be beneficial. • We’re actively searching for talented and expereinced professionals who are ready to experience the True Zero difference. As a True Zero team member, you'll enjoy: • Competitive salary, paid twice per month • Best in class medical coverage • 100% of medical premiums covered by True Zero • Company wide new business incentive programs • Contribution Incentives (i.e. white papers, blog posts, internal webinars, etc.) • 3 weeks of PTO starting + 11 Paid Holidays Annually • 401k Program with 100% company match on the first 4% • Monthly reimbursement of Cell Phone and Home Internet costs • Paternity/Maternity Leave

Responsibilities

• Design and implement enterprise Zscaler Private Access (ZPA) architectures, including App Connector placement, redundancy, capacity planning, application segments, access policies, and naming standards. • Configure and harden the ZPA tenant using least-privilege administrative roles, appropriate administrator authentication requirements, and secure platform configuration standards. • Develop and implement Zscaler Client Connector configurations that can coexist with third-party agency VPN clients without disrupting access to agency-owned resources. • Design 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. • Engineer 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. • Validate 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. • Integrate ZPA with enterprise identity services, including SAML federation with Okta and identity/group mappings used to enforce access policies. • Configure Zscaler Log Streaming Service (LSS) and integrate ZPA activity and security logging with Rapid7 InsightIDR or comparable SIEM/security monitoring platforms. • Develop repeatable migration procedures for onboarding organizations and applications, including application publishing, identity/group mapping, legacy VPN or tunnel cutover, validation, rollback, and decommissioning activities. • Produce detailed as-built documentation covering the production ZPA tenant, App Connectors, application segments, policies, security hardening, and supporting configurations. • Develop operational runbooks and troubleshooting procedures for administrators, helpdesk personnel, technical agency contacts, and other support teams. • Provide technical guidance and knowledge transfer to internal engineering and security teams, including train-the-trainer sessions and post-deployment hypercare support.
