## Job description

## 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

1. Active intrusion or suspected compromise
2. Service-affecting outage
3. Degradation and early warning signs
4. 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.

## Benefits & Perks

Knox offers a competitive employee benefits package including Medical, Dental, Vision, Life & Disability, unlimited PEO, and an employee funded 401k plan. Please note, benefits are subject to change.

We are an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. Employment decisions are made without regard to race, color, religion, sex, sexual orientation, gender identity or expression, national origin, age, disability, veteran status, or any other legally protected status.

Knox is proud to support veteran hiring — we encourage veterans and transitioning service members to apply and welcome the unique skills and experience you bring.

## About Knox Systems

## Company Overview
- **One-liner**: Knox Systems provides a managed cloud infrastructure and compliance platform that accelerates FedRAMP authorization for SaaS companies to 90 days at 90% lower cost.
- **Entity Type**: Private (Venture-backed; Series A)
- **Headquarters**: Austin, Texas, United States
- **Founded**: 2025
- **Founders**: Not publicly available

## Core Business
- **Primary Industry**: Computer and Network Security (FedRAMP / Government Cloud Compliance)
- **Target Customers**: B2B SaaS companies that need to deploy in FedRAMP Moderate, High, or DoD IL4 environments to sell to U.S. federal and defense agencies.
- **Mission Statement**: “FedRAMP in 90 Days for 90% Less.”

## Products & Services
- **Knox Cloud**: A managed cloud infrastructure platform that provides single-tenant isolation for every customer application. Deployed on AWS, Azure, and GCP. Includes pre-built architecture and CI/CD pipeline integration.
- **KnoxAI**: A proprietary AI-powered monitoring and issue remediation engine trained on 10 years of federal audit data. Handles real-time security monitoring, contextual decision-making, and compliance artifact generation.
- **FedRAMP Authorization Service**: A turnkey service that handles the full authorization process, including architecture review, scanning, remediation, and sponsor management. Customers inherit Knox’s existing 15+ ATOs, eliminating the need to find a sponsoring agency.

## Market Standing
- **Valuation**: Not publicly available
- **Total Funding**: USD 31.5M
    - Seed Round (August 2025): USD 6.5M led by **Felicis** with 3 investors
    - Series A (March 2026): USD 25M led by **B Capital** with 7 investors
- **Key Metric**: 20+ customers authorized in 90 days or less; 16 federal sponsors (including FEMA for Fed High); 15+ ATOs across civilian and DoD agencies.
- **Notable Investors/Partners**: B Capital, Felicis, Irina Denisenko (CEO). The platform is battle-tested from running enterprise applications for Adobe, Celonis, and BigID.

## Competitive Advantages
- **Speed and Cost**: 90-day timeline versus the traditional 12–24 month FedRAMP process; claims 90% cost reduction vs. doing it in-house.
- **Sponsor Network**: Customers do not need to find a federal sponsor—they inherit Knox’s 15+ existing ATOs across DHS, FEMA, Marines, Treasury, VA, and others.
- **Single-Tenant Isolation**: Dedicated, isolated sub-account per customer (no shared tenant data), reducing blast radius and preventing lateral movement.
- **Proven Track Record**: 10 years of experience running enterprise applications in federal environments; 100% success rate despite government shutdowns.
- **AI-Native Compliance**: KnoxAI is trained on 10 years of audit data and achieves 99% audit artifact coverage.

## Strategic Focus
- **Platform Expansion**: Targeting DoD IL5 authorization by late 2026.
- **Multi-Cloud Depth**: Deepening integrations with AWS, Azure, and GCP to remain cloud-agnostic.
- **Go-to-Market Scaling**: Building out channel and demand generation teams (open roles: Director of Channels, Director of Demand Generation & ABM).
- **Product Development**: Enhancing KnoxAI capabilities including contextual decision engine, QA agents, compliance reasoning model, and analytics insight engine.

## Why Work Here
- **Mission-Driven Impact**: Directly enable U.S. government digital transformation by helping innovative SaaS companies get to FedRAMP quickly and securely.
- **Growth Trajectory**: Rapidly scaling startup (43 employees, +1,250% YoY) with significant Series A funding—ample opportunity for ownership and career acceleration.
- **Hybrid Work Policy**: Knox maintains a hybrid workspace model with offices in Austin, TX, and allows remote work for certain roles.

- **Recent Open Roles** (as of mid-2026): Senior Full-Stack Engineer, Senior Backend Engineer, DevOps Security Engineer, Director of Channels, Jr. IT Administrator.
