Systems Administrator

The Role

We're seeking a Systems Administrator to architect, deploy, secure, and maintain the core systems powering our organization — spanning both corporate IT and the operational technology (OT) behind our deployed microgrids. This dual role blends hands‑on engineering with day‑to‑day administration, with heavy emphasis on access/permissions management, security hardening and compliance (NIST, ISO 27001, SOC
2), network administration, remote connectivity, and monitoring across IT and field OT assets. Strong networking fundamentals are required; hands‑on OT/ICS experience in energy, utilities, or renewables is strongly preferred.

This hybrid role will report to our Sr Manager, IT and be based in our HQ in Ridgewood, NJ.

• Systems Engineering: Design, deploy, and maintain server, storage, and virtualized infrastructure (cloud and on‑prem), including Windows Server, Linux, Active Directory/Azure AD, and automation/IaC practices.
• Administration: Own identity and access management end‑to‑end (onboarding/offboarding, role‑based permissions, MFA, privileged access, backups, audit logging); apply patches/updates and maintain system health and availability.
• Security & Compliance: Serve as primary owner of access governance and least‑privilege design; administer EDR, SIEM, MDM, and vulnerability management tools; extend controls into OT (segmentation, secure remote access); support SOC 2/ISO 27001 audit readiness and incident response.
• Troubleshooting & Support: Provide Tier 1–3 support across Windows, macOS, Linux, virtualization, and cloud; engage vendors as needed.
• Cloud Administration: Manage Microsoft 365, Google Workspace, and Azure (VMs, storage, identity, conditional access); implement cloud backup/DR.
• Network & Connectivity: Design and maintain switching, routing, VLANs, firewalls, and VPNs; configure cellular modems/gateways for microgrid site connectivity (carrier/APN/SIM provisioning, NAT, failover); build secure IT/OT remote access paths.
• OT & Field Systems: Support microgrid controllers, PLCs, HMIs, SCADA, inverters, and meters; troubleshoot protocol‑level issues (Modbus, DNP3, MQTT, SNMP, BACnet); partner with Scale’s control team for on‑site commissioning and OT patch/firmware management.
• Monitoring & Observability: Build and tune monitoring/alerting across IT and OT (health, connectivity, data flow, backups, security events); create dashboards and reduce MTTD/MTTR.
• Documentation: Maintain system/network diagrams, SOPs, configuration baselines, and runbooks; generate performance and capacity reports.

• Bachelor's degree in IT, Computer Science, or related field (or equivalent experience); 5+ years as a Systems Engineer/Administrator with direct network administration responsibility.
• OT/ICS/SCADA experience in energy, utilities, renewables, or industrial/building systems strongly preferred.
• Demonstrated experience with NIST, ISO 27001, and/or SOC 2 frameworks.
• Certifications preferred:
  Network+/Security+, CCNA, Azure Administrator, MCSA/MCSE, RHCSA, GICSP, or similar.
• Technical Proficiency:
  Windows Server, Linux (Ubuntu/CentOS), Active Directory, Azure AD, Group Policy, M365; VMware/Hyper‑V.
• Strong networking fundamentals: TCP/IP, subnetting, routing, VLANs, DNS/DHCP, NAT, firewalls, VPNs.
• Hands‑on experience with cellular modems/industrial gateways (Cradlepoint, Sierra Wireless, Digi, Teltonika, Peplink) and carrier/SIM management.
• Monitoring/alerting tools (PRTG, Solar Winds, Datadog, Zabbix, Grafana); backup/DR platforms (Veeam, Datto).
• Familiarity with industrial protocols and IT/OT segmentation;
  Zero Trust and NIST 800‑82/IEC 62443 knowledge a plus.
• Strong analytical and communication skills; highly organized and detail‑oriented; collaborative, customer‑focused mindset
• Willingness to travel to office, project, and client sites, including field visits to operating microgrid sites. Approximate travel 25%.
• Ability to participate in an on‑call rotation and evening/nighttime system migration tasks when required.
