Location: Knoxville, TN or Madison WI

Salary: Highly Competitive Plus Benefits

Contract: Permanent, full time

Reporting to: Director of IT

Your role in the mission:

The Cyber Security Engineer will be the primary hands‑on security operator, responsible for day‑to‑day cyber security operations and the implementation and operation of core security platforms. This role partners closely with the Director of IT, who sets security strategy, priorities and risk tolerance, while the Cyber Security Engineer executes, operates and continuously improves the technical security program.

The Cyber Security Engineer is responsible for coordinating closely with the MSP on these services, ensuring they are correctly configured, monitored and aligned with internal security objectives. While certain operational tasks are delegated, accountability for security outcomes remains internal.

This role will play a central part in establishing durable, auditable and defensible cyber security operations.

• Own day‑to‑day internal cyber security operations and outcomes.
• Monitor, triage and investigate security alerts and incidents.
• Act as the primary internal technical responder for security events.
• Coordinate closely with the MSP on managed security services (including Sentinel One), retaining internal accountability.

• Implement, configure and operate core security platforms, including Zscaler and Aurascape.
• Design and enforce security policies; integrate with identity, endpoint and network systems.
• Serve as technical owner for MSP‑managed platforms by defining standards, reviewing findings and validating response actions.
• Lead implementation and operation of a SIEM platform, including logging standards, alerting and workflows.

• Lead technical investigation, containment and remediation of security incidents.
• Conduct post‑incident reviews and recommend control improvements.
• Operate vulnerability scanning and configuration assessment tools.
• Prioritize and track remediation based on risk and business impact.

• Implement and operate technical controls supporting CMMC Level 2 and NIST 800‑171.
• Maintain defensible documentation of security controls and operations.
• Support audits, investor due diligence and third‑party security assessments.
• Partner with leadership to identify and remediate gaps.

• Work closely with the Director of IT on priorities, risk acceptance and escalation decisions.
• Advise IT, engineering and research teams on secure system design and operational trade‑offs.

What you’ll need:

• Strong hands‑on understanding of modern security principles and threat models.
• Practical experience securing Linux and Windows systems.
• Solid networking fundamentals (firewalls, segmentation, VPNs, DNS).
• Experience operating security platforms such as SSE/CASB, EDR, vulnerability scanners and SIEMs.
• Ability to automate and script security tasks using Python, Bash or Power Shell.

• Experience securing cloud environments (AWS, Azure or GCP).
• Familiarity with IAM, logging, monitoring and cloud network security.
• Experience with containerised workloads, CI/CD pipelines or HPC environments is a plus.

• Demonstrated experience investigating and responding to security incidents.
• Ability to analyse logs and alerts to distinguish real risk from noise.
• Calm, methodical approach to incident handling under pressure.
