Implementation Manager OT_Infrastructure

IT - OT Implementation Manager Infrastructure

Role Summary

IT

What You’ll Do

• Program & rollout management

• Convert HLD/LLD into executable plans, site waves, and cutover calendars; manage scope, schedule, cost, quality, risk, and comms across multiple sites.
• Build and maintain

  Implementation Playbooks

  (MOPs, prechecks, rollback, SAT/acceptance) and standard work packages (S/M/L site patterns with reference BOMs).

• Execution on the plant floor

• Lead coordinated installs and cutovers for L2/L3 networks, routed cells/VLANs, firewalls/DMZ, jump hosts/remote access, OT AD/identity prerequisites, servers/virtualization, NVR/VMS backbones, industrial Wi-Fi, and historian/OPC connectivity (infra side).
• Orchestrate maintenance windows and shutdowns with production and

  EHS

  (LOTO, permits, toolbox talks).

• Security & compliance by default

• Enforce

  IEC 62443 / NIST 800-82

  aligned designs, labeling, media control, allow-listing, and time-sync (

  PTP/NTP

  ) checks; ensure logging/backup prerequisites before go-live.

• Operational readiness & hypercare

• Ensure spares lists, backups/DR runbooks, as-builts, and

  CMDB/asset

  updates are complete; run hypercare and transition to steady-state support.

• Lifecycle coordination

• Plan firmware/OS upgrades and EOL transitions with minimal downtime; schedule patch windows and verify post-change health.

• Reporting & governance

• Maintain RAID logs, earned value/burn-down (where applicable), and site readiness dashboards; present status to OT Leadership and stakeholders.

What You Bring

Must-Have

• 6–8+ years delivering

  OT/industrial infrastructure

  projects with multi-site rollouts.
• Strong knowledge of

  Purdue/OSI 0–7

  , plant operations, and EHS practices.
• Demonstrated experience coordinating: switching/routing (L2/L3, VLANs),

  routed cells

  , firewalls/DMZ/jump hosts, secure vendor access,

  PTP/NTP

  validation, virtualization (e.g., VMware/Hyper-V), backup/restore, and NVR/VMS backbones (infra perspective).
• Hands-on change control and

  MOP/rollback

  execution in live plants.
• Vendor/SI management (SOWs, SAT/acceptance, SLAs) and budget control (CapEx/OpEx, change orders).
• Clear documentation discipline (runbooks, as-builts, asset tagging/CMDB).
• Excellent communication with operators, maintenance, controls/OT, IT security/network, EHS, and procurement.
• Willing to travel

  ~10%

  ; occasional international travel.

Nice-to-Have

• IEC 62443 credentials or ISA/industrial security training; networking/security certs (e.g., CCNP/FortiNet/PCNSE).
• Exposure to

  historian/OPC UA

  infra patterns, certificate handling, and brokered data flows.
• Familiarity with ITIL service transition/operations and light automation (PowerShell/Python) for validation or documentation tasks.

What You Will Not Do

• No MES/application build/run.

• No PLC/DCS programming.

  You manage infra pre-requisites and the deployment program.

Day-to-Day Tools & Environment

• ServiceNow (Ideas Demand Project, changes), MS Project/Planner, SharePoint/Teams,

  Visio

  , Excel/Power BI for dashboards.
• Close collaboration with OT Architects, OT Area Coordinators, Plant Engineering/Maintenance, Network/Security, EHS, Procurement, and approved SIs under strict change control/MOC.
