Sr. IT Engineer

What is a
Sr. IT Engineer ?

The Sr. IT Engineer owns the infrastructure and systems engineering that SEF Energy and its subsidiaries run on – cloud platforms, networking, identity and accounts, and the Freedom Series field-compute hardware fleet. This is a senior, hands-on individual-contributor role based on-site in Oklahoma City, where the field-compute fleet is built, imaged, and staged. The role carries the company's core infrastructure knowledge: it designs, validates, and operates the systems the business runs on, and it directs the work of managed-service partners with full command of what they deliver.

In this role, you will:

• Own cloud infrastructure across Microsoft Azure and AWS: architecture, administration, security posture, and cost management, coordinating managed-service partners with full internal command of the environment
• Administer identity, accounts, and endpoints alongside the existing IT engineering team:
  Microsoft 365, Entra , Intune, and Defender
• Lead mesh networking R&D and rollout: evaluate, pilot, and standardize mesh radio technology (Rajant, Mimosa) for pad and facility connectivity
• Carry infrastructure projects end to end:
  Windows 11 rollout and Power Shell-based deployment at scale, Peplink SD-WAN standardization, branch-site network buildouts, dedicated circuits, and Starlink fleet management
• Own the lifecycle of the Freedom Series field-compute hardware fleet (FSL, FSiC, FSDI) and control-center units (FSCC): imaging, configuration, build, staging, shipping, and spares, based out of the Oklahoma City facility
• Administer communication and physical-security platforms: cloud telephony (Dialpad), cameras, and door-access systems (Uni Fi)
• Maintain field data-ingestion standards and SOPs for Freedom Series operations, including channel-naming and data-quality conventions
• Run IT procurement and vendor management: quotes, RFPs, orders, contractor coordination, and vendor escalations for hardware and connectivity
• Own inventory and asset management: equipment audits, asset records (Meraki, Starlink), and fleet inventory accuracy
• Resolve infrastructure and systems tickets in the IT ticketing system (Freshdesk)
• Support business and engineering platforms as part of the IT engineering team: QHSE platform (forms, tablets), engineering applications (Solid Works), and Share Point
• Occasional travel to branch sites and company facilities may be required, estimated less than 10% of time (must possess a valid driver's license and meet the company driver requirement to operate a company vehicle while traveling)
• Perform other duties as assigned

Required and

Preferred Experience:

• 5+ years in IT engineering / systems administration with demonstrated end-to-end ownership of infrastructure projects
• Hands-on cloud administration:
  Microsoft Azure required, AWS strongly preferred; formal cloud training or certification is a plus
• Networking depth: SD-WAN (Peplink or equivalent), branch networking, and field connectivity (cellular, satellite, mesh radio)
• Microsoft 365 / Entra  and endpoint management (Intune, Defender)
• Hardware fleet experience: imaging and deployment at scale (Windows, Power Shell), industrial or ruggedized compute hardware, and device lifecycle management
• Procurement and vendor coordination for IT hardware and services
• Self-directed with exceptional time management; capable of owning parallel work streams with limited day-to-day oversight
• Oilfield or industrial field-systems exposure is a plus but not required

Work Environment and

Physical Requirements:

• Office and equipment-staging environment of an oil & gas manufacturing and servicing company
• Occasionally required to stand, sit, use hands to manipulate with fingers, handle or feel, walk, reach with hands and arms
• Lift, push, pull up to 50…
