Sr. IT EngineerDesired Traits: Dynamic, Accountable, Returns-Driven, Commercial, Integrity
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 ID, 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 PowerShell-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 (UniFi)
- 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 (SolidWorks), and SharePoint
- 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 ID administration and endpoint management (Intune, Defender)
- Hardware fleet experience: imaging and deployment at scale (Windows, PowerShell), 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 workstreams 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 lbs. (SEF Energy employees shall not manually lift an item weighing more than 50 lbs.; utilize mechanical assistance devices or a team lift)
- Quiet conditions
Education:- Bachelor's degree in Computer Science, Information Systems, Information Technology, or a related field
- Industry certifications (Microsoft Azure, AWS, Cisco or equivalent networking) are a plus
- Experience may be substituted for the bachelor's degree: 8+ years of progressive IT engineering experience with demonstrated results
