remediate vulnerabilities in partnership with cybersecurity.\nSupport compliance requirements (such as CMMC, NIST SP 800-171, and FedRAMP) by maintaining configuration documentation, logs, and access reviews, and providing evidence for audits.\nReview technical designs and changes, follow the change control process, and communicate maintenance windows and impacts to stakeholders.\nEvaluate and recommend tools and technologies, and contribute to the infrastructure roadmap, capacity planning, and budget inputs.\nCreate and maintain system documentation, runbooks, and architecture diagrams.\nParticipate in an on-call rotation and occasional after-hours maintenance windows for critical systems.\nTravel: minimal, up to roughly 10% (occasional trips to company offices and new sites).\nPhysical demands: primarily sedentary work at a computer;

security certification such as Security+ or CISSP.\nExperience with infrastructure as code and CI/CD tooling (Terraform, Git-based workflows, or pipelines).\nExperience supporting CMMC, NIST 800-171, or FedRAMP assessments, and an active U.S. government security clearance or the ability to obtain one.\nWhy CHAOS?\nHealth Benefits: Medical, dental, and vision benefits 100% paid for by the company\n Additional benefits: 401k (+ 50% company match up to 6% of pay), FSA, HSA, life insurance, and more\nOur Perks: Free daily lunch while you're working onsite, fully-stocked kitchen, unlimited PTO, casual dress code\n Compensation Components: Competitive base salaries, generous pre-IPO stock option grants, relocation assistance, and (coming soon!) annual bonuses\nTeam Growth: 500+ employees and counting across 5 global offices\nSalary Range: $140,000 - $200,000\nThe stated compensation range reflects only the targeted base compensation range and excludes additional earnings such as bonus, equity, and benefits.
