  • Support the design, documentation, and ongoing optimization of security system architecture across servers, applications, databases, networks, and integrated security platforms.
  • Maintain SQL databases supporting security applications, including database health, performance, backups, troubleshooting, and data integrity.
  • Partner with internal R&D, IT, network, security technology teams, and external vendors to support integrations, resolve technical issues, and implement system enhancements.
  • Conduct system health checks, technical assessments, and testing to validate system stability, performance, and functionality before and after upgrades or major changes.
  • Serve as a technical point of contact for security technology vendors and support escalations, upgrades, system improvements, and issue resolution.
  • Maintain accurate technical documentation, system architecture diagrams, configuration records, maintenance procedures, and operational standards.

Required Skills and Experience

  • 7+ years of experience engineering, administering, and supporting enterprise physical security systems, applications, and supporting infrastructure.
  • Strong hands-on experience with Lenel OnGuard and Avigilon CCTV systems, including administration, troubleshooting, upgrades, and system maintenance.
  • Strong experience administering enterprise servers, including operating system updates, security patches, backups, configuration, and performance monitoring.
  • Experience with SQL databases, including database administration, troubleshooting, backups, queries, and performance management.
  • Strong understanding of enterprise system architecture, networking, infrastructure, and security concepts, including LAN/WAN, IP addressing, DNS/DHCP, firewalls, Active Directory/domains, and server environments.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
