Job summary

Knox Systems, Inc. is seeking a NOSC Manager to lead the evening shift (14:00–22:00) on the security operations floor. You will set escalation criteria, drive incident response, and mentor junior analysts in a fast-paced federal-focused environment.

This role emphasizes hands-on leadership, standard-setting across logs, runbooks, and reviews, and collaboration with FedRAMP evidence work. A strong track record in cloud security monitoring and incident handling is required.

Qualifications

• Run root cause on anything that reached containment, and update the runbook so it doesn’t recur.
• Set and hold the standard for shift logs, handovers and queue health across all shifts.
• Develop the Tier 1 and Tier 2 analysts. Their readiness for promotion is part of your job.
• Represent the team in incident reviews and FedRAMP evidence work.

About Knox Knox runs the largest Federal & DoW managed cloud, building and operating secure cloud and AI environments that support the U.S. government’s most critical missions — from national security and public safety to essential public services. Our customers rely on Knox to deploy production systems that meet the highest standards for security, reliability, and compliance. Work at Knox is high-impact and purpose-driven. The problems we solve are high-stakes, the expectations are high, and the results are visible. Speed, rigor, and trust matter here - because the environments we secure cannot fail. Your contributions are visible, your expertise is relied upon, and the impact of your work is immediate and measurable. We operate at federal scale, securing some of the most sensitive government environments in the country - because the systems we build must perform without fail.

How We Work Most companies run a security team and a network team separately. We don’t. At Knox one team watches everything — performance, availability and security — out of the same queue. You see the whole picture, and a problem never sits with the wrong team while the clock runs. It is a better way to work and a much faster way to learn.

How We Prioritize

• Active intrusion or suspected compromise
• Service-affecting outage
• Degradation and early warning signs
• Customer requests and tickets

When the right answer isn’t obvious, you’re the one who decides. That call is part of the role, not a favor we’re asking.

What You'll Do

• Lead the evening shift as the senior person on the floor from 14:00 to 22:00.
• Set the escalation criteria — what wakes a manager, what waits, and what the team handles alone.
• Run root cause on anything that reached containment, and update the runbook so it doesn’t recur.
• Set and hold the standard for shift logs, handovers and queue health across all shifts.
• Develop the Tier 1 and Tier 2 analysts. Their readiness for promotion is part of your job.
• Represent the team in incident reviews and FedRAMP evidence work.

What You'll Need

• Five or more years in security operations, including time as the senior person on a floor.
• A track record of developing people, not only of resolving incidents.
• A strong grounding in cloud security monitoring, detection engineering and incident response.
• The confidence to set a standard and hold the team to it.

What We'll Teach You

• How FedRAMP controls and evidence work inside a federal authorization boundary.
• Our environment, our customers, and how security and availability work fit together here.
• Where this role goes next — NOSC Manager is the position above it.

What We Don't Require

• A degree.
• Previous corporate experience.
• An active security clearance. If you hold one, or held one, that’s a plus — it is never a requirement.

What We Offer

• Your schedule is fixed and published ahead of time. Shifts do not rotate.
• Three consecutive days off every week on the four-day rotation schedules.
• Certification costs and renewals covered, including the first attempt and a retake.
• Shift premium paid on the hours you actually work in a premium window, at a published rate.
• A published salary band, and a published band for the level above you.
• We are a small team, so what you do is visible. You will make an impact.

Compensation Range: $125k-$160k, variable annual bonus, equity and monthly premium payments.

Hiring Requirement: Due to the nature of our work with federal government clients and compliance with applicable regulations, this position requires U.S. citizenship. Dual citizenship is not permitted for this role. Candidates must be able to provide documentation verifying sole U.S. citizenship status as part of the background check process and ability to pass a government background investigation.

Any offer of employment is contingent upon the successful completion of all required pre-employment screenings, including a background check, in accordance with applicable laws and government contract requirements.
