As a Solution Architect, you’ll play a key role in assessing, designing, and implementing the network and infrastructure systems behind technical and infrastructure projects, including cybersecurity and operational technology (OT) network work. You’ll work closely with a program manager, project managers, and technical teams to shape how networks, servers, databases, applications, and workstations come together, helping ensure our work is not only smart, but clear, relevant, and actionable. This role is ideal for someone who enjoys working at the intersection of IT infrastructure, network architecture, and OT security, brings strong judgment to complex problems, and wants to contribute to work that shapes real-world decisions in the energy industry.

In this role, you will:

• Assess current network design, including routers, switches, firewalls, wireless systems, segmentation, and monitoring tools, and recommend changes

• Review architecture documentation remotely, and provide onsite support to gather network topology information for systems that can’t be accessed remotely

• Identify critical gaps, legacy systems, and technical debt across business and technical environments, and recommend improvements

• Translate business and technical requirements into architectural blueprints, and document all solution architecture design and analysis work

• Support the design and implementation of technical and infrastructure systems for cybersecurity and OT network projects

• Implement network routes that allow monitoring tools to communicate between sites

• Support the deployment and integration of physical and virtual servers, databases, and workstations, from configuration through operational readiness

• Coordinate with network, server, database, security, application, and operations teams to make sure every part of the solution is properly integrated

• Troubleshoot connectivity, routing, access, and performance issues across new, existing, and legacy systems, including systems no longer supported by the original manufacturer

• Develop and maintain architecture diagrams, network drawings, implementation plans, and operational and support documentation

• Provide onsite or remote support during testing, cutover, stabilization, and handoff to operations teams

You’re likely a great fit if you:

• Have a strong general understanding of both modern and legacy technology stacks

• Can troubleshoot across interconnected network, server, application, database, and security environments

• Turn business and technical requirements into infrastructure solutions that can be implemented

• Communicate clearly, in writing and in conversation, with project managers, technical and cybersecurity teams, vendors, and business stakeholders

• Work well as part of a project team led by a program or project manager

And even better if you:

• Have experience working with or around utilities, energy, consulting, research, or adjacent fields

• Understand IT/OT network architecture, segmentation, security zones, and defense-in-depth principles, including the Purdue Model and IT/OT demilitarized zone (DMZ) architecture

• Are familiar with industrial control system (ICS) and supervisory control and data acquisition (SCADA) environments, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), remote terminal units (RTUs), historians, and engineering workstations

• Know industrial protocols such as Modbus, DNP3, OPC/OPC UA, and EtherNet/IP

• Are familiar with cybersecurity frameworks such as NIST SP 800-82, ISA/IEC 62443, or the National Institute of Standards and Technology (NIST) Cybersecurity Framework

• Can assess legacy or unsupported OT technologies and recommend appropriate compensating controls

• Have hands-on experience with tools such as Cisco, Juniper, or Aruba networking; Palo Alto or Fortinet firewalls; Wireshark, SolarWinds, or PRTG; Splunk, QRadar, or Microsoft Sentinel; Dragos, Claroty, or Nozomi; VMware or Hyper-V; Active Directory or Entra ID; and PowerShell, Python, or Ansible

Experience and Skills to Qualify Include:

• 7+ years of experience in solution architecture, infrastructure architecture, network engineering, systems engineering, or a related technical role

• Experience assessing, designing, implementing, and troubleshooting enterprise network and infrastructure environments

• Strong understanding of routing, switching, firewalls, virtual local area networks (VLANs), network segmentation, TCP/IP, DNS, DHCP, virtual private networks (VPNs), and network monitoring

• Experience across servers, databases, applications, workstations, virtualization, and network infrastructure

• Experience developing network and architecture diagrams, technical designs, implementation plans, and operational documentation

• Experience supporting both legacy and modern technology environments, including integration and compatibility needs

At E Source, you’ll work alongside people who are thoughtful, curious, and deeply knowledgeable about utility and energy systems. We value clarity over jargon, substance over flash, and collaboration over ego. You’ll have the opportunity to grow your skills, contribute to meaningful work, and help shape a company that plays a real role in how the energy future unfolds.

What you can expect

• Excellent insurance options, including medical, dental, and vision plans; company-paid life insurance; company-paid long- and short-term disability insurance; medical and dependent-care flexible spending plans, and paid parental leave.

• A flexible time off (FTO) policy that provides paid time away from work, approved by your manager, while ensuring business needs, workload commitments, and appropriate coverage are maintained.

• A 401(k) plan with a 3% employer match.

The budgeted salary for this position is $100,000 to $125,000 USD + annual bonus. Actual pay will be adjusted based on experience.

This role will be remote, with onsite support at project sites as needed (up to 25%).
