Sr. Infrastructure Engineer

Atlas Energy Solutions•Austin, TX

6d•Onsite

About The Position

The Sr. Infrastructure Engineer is responsible for designing, implementing, and supporting the infrastructure that powers Atlas Energy Solutions’ business and production operations across both IT and OT environments. This role ensures reliable, secure, and scalable platforms across manufacturing sites, remote locations, and corporate operations, including networking, virtualization, Windows server platforms, cloud infrastructure, identity services, monitoring, backup/DR, and cybersecurity controls. This position will work closely with Technology Operations, Automation/Controls, Cybersecurity, and vendors to maintain uptime for operational systems such as SCADA/ICS platforms, plant networks, and production-facing services, while also improving standards, resilience, and repeatability across the infrastructure footprint. This role will be based in Austin, TX, with travel as necessary up to 50% depending on the phases and needs of projects.

Requirements

7+ years in infrastructure engineering (systems/network), ideally supporting industrial, energy, or manufacturing environments
Strong networking fundamentals (switching/routing, VLANs, firewalls, VPN, troubleshooting)
Strong Windows Server administration (AD/DNS/DHCP/GPO) with patching and hardening experience
Experience with virtualization (VMware/Hyper-V) and associated storage/backup practices
Hands-on Azure infrastructure (identity integration, VNets/VPN, compute/storage, monitoring, backup)
Experience delivering and supporting site/plant deployments (racks/cabinets, circuits, redundancy, remote operations)
Apply working knowledge of OT/ICS concepts (SCADA, industrial segmentation, operational reliability) to keep critical operations running safely and efficiently
Bring a security-minded approach (segmentation, access control, logging) and leverage monitoring/alerting tools to protect the organization's infrastructure
Drive strong troubleshooting and root-cause analysis across network, systems, cloud, and hybrid IT/OT connectivity to minimize downtime and resolve issues fast
Develop infrastructure standards and documentation, and produce practical technology architecture recommendations that scale with the business

Responsibilities

Design, implement, and support hybrid IT/OT infrastructure across plants, logistics sites, and corporate environments to ensure uptime for production-critical services
Engineer and support network infrastructure (switching/routing, VLANs, segmentation, firewalls, VPN, wireless) including secure OT connectivity
Administer Windows Server services (AD, DNS/DHCP, GPO, file/print) with standard patching and hardening practices
Maintain virtualization (VMware/Hyper-V) including host lifecycle, storage integration, patching, and capacity planning
Own Azure infrastructure (identity integration, VNets, routing, compute/storage, monitoring, and backup) for scalable hybrid operations
Implement and test backup/DR for on-prem and cloud workloads; maintain recovery runbooks and validation evidence
Operate monitoring/alerting (e.g., PRTG or similar) for circuits, networks, servers, and critical plant connectivity
Support OT connectivity for SCADA/ICS, industrial HMIs, and edge systems with clear demarcation and secure access patterns
Partner with Cybersecurity to enforce segmentation, least privilege, MFA where appropriate, logging, and vulnerability remediation in IT/OT environments
Establish and maintain infrastructure documentation standards (network diagrams, system inventories, configuration baselines, and runbooks) to improve supportability and repeatability
Develop technology architecture recommendations and roadmaps (network, compute, cloud, and OT connectivity) aligned to security, reliability, and operational requirements
