OT Security Engineer

Solaris is building out networked power generation and distribution assets across multiple customer sites. Site networks reach down to turbine and balance-of-plant equipment, SCADA runs on Ignition, and protection and control includes SEL devices connected over SEL software-defined networking.

This environment is being designed and deployed now - which means security can be built in rather than retrofitted. That is the opportunity in this role.

As our OT Security Analyst, you will help design secure operational technology systems as sites are built, then continuously validate and monitor that what was designed is what is actually running. This is a newly created position reporting directly to the SVP of Information Technology and working as a peer to our enterprise Cybersecurity Analyst.

Design at Solaris is collaborative. You will work side by side with Engineering and IT Systems, bringing the security requirements, standards, and risk perspective to the table while remaining accountable for the security posture of what gets built. You will not inherit a mature program, you will create one.

Essential Functions

Secure by design

Partner with Engineering and IT Systems on network design for each new site build, bringing security requirements into the design process early

Contribute to SDN flow policy design and review, ensuring engineered flows are least-privilege, documented, auditable, and current as sites change

Develop and maintain a reference architecture for OT network segmentation that scales across sites

Define hardening baselines for Ignition gateways, SEL device management, industrial switching, and OT endpoints

Establish secure remote access for internal teams, OEMs, and third-party service providers, including authentication, session logging, and approval workflow

Evaluate the current security stack against OT requirements and recommend tooling to close identified gaps

Monitor and validate

Build and maintain OT network visibility and asset inventory across all operating sites

Extend existing enterprise security tooling into OT where safe, and recommend purpose-built platforms where passive or protocol-aware monitoring is required

Run continuous vulnerability management against industrial assets using a risk-based, operationally realistic remediation approach

Monitor for anomalous OT network activity; triage, investigate, and escalate

Periodically audit deployed sites against design standards and close configuration drift

Respond and govern

Maintain and exercise OT incident response playbooks; lead or support OT-involved incidents

Produce audit evidence supporting SOX ITGC where OT systems touch financial reporting

Maintain OT security policy and standards documentation aligned to IEC 62443 and NIST CSF

Support customer security questionnaires and contract security reviews

Provide OT security input to Engineering and Operations on new equipment and vendor selection

Experience/Education

Bachelor's degree in Cybersecurity, Computer Science, Engineering, or a related technical field, or equivalent practical experience

4+ years in cybersecurity, including a minimum of 2 years hands-on in operational technology, industrial control systems, or SCADA environments

Demonstrated experience designing or reviewing segmented industrial networks, including the Purdue reference model and zone/conduit architecture

Working knowledge of industrial protocols such as Modbus, DNP3, OPC UA, or IEC 61850

Experience with vulnerability management in environments where devices cannot be freely scanned, patched, or rebooted

Hands-on comfort configuring and hardening industrial network equipment and firewalls

Preferred

Hands-on experience with Ignition or a comparable modern SCADA platform

Experience with SEL software-defined networking (SEL-2740S, SEL-5056 flow controller) or comparable OT SDN environments

Familiarity with SEL relays, SEL management tooling, or utility protection and control environments

Background in power generation, utilities, energy infrastructure, or oil and gas

GICSP, GRID, or ISA/IEC 62443 certification

Experience with OT monitoring platforms such as Claroty, Nozomi, Dragos, or Tenable OT

Experience with Rapid7 InsightVM or InsightIDR

Prior hands-on engineering or operations experience in addition to security
