We are seeking a seasoned Endace Implementation and Sustainment Engineer to architect, deploy, integrate, and operate Endace packet capture, monitoring, and network recording platforms across a large, distributed enterprise. The ideal candidate has deep experience in network forensics, packet analytics, and telemetry architecture, combined with hands‑on familiarity supporting Zero Trust visibility and segmentation strategies.

This role owns the end-to-end lifecycle for Endace systems, including design, installation, configuration, maintenance, and long‑term optimization, while integrating the platform with SIEM or SOAR, detection engineering, analytics tooling, and broader Zero Trust security controls.

You will lead the design, deployment, and configuration of Endace appliances for enterprise‑scale packet capture. You will develop packet capture strategies aligned to network architecture, mission requirements, and Zero Trust visibility controls. You will build high‑availability, scalable, and resilient Endace clusters across data centers and cloud‑connected environments. You will integrate Endace with analytics ecosystems. You will maintain and tune Endace hardware and software for optimal performance, including upgrades, patching, sensor tuning, and storage lifecycle.

You will troubleshoot packet loss, timing drift, flow‑indexing issues, clock synchronization, and performance bottlenecks. You will monitor device health, capacity, and telemetry fidelity to ensure consistent and forensically sound data capture. You will manage PCAP retention strategies, indexing policies, and storage allocation across distributed deployments. You will align Endace visibility architecture with Zero Trust telemetry requirements and continuous verification workflows.

You will ensure packet capture and telemetry support identity‑aware network segmentation and policy enforcement. You will support the development of traffic baselines, segmentation decisions, and enforcement models using Endace data. You will automate deployment, configuration, and sustainment workflows using Ansible, Terraform, or scripting. You will build dashboards, runbooks, playbooks, and investigation workflows for SOC, threat hunters, and IR teams. You will partner with network engineering, cloud teams, and security operations to ensure full‑spectrum telemetry coverage.

You will deliver training and guidance to operational teams on Endace platform usage and best practices.
