IT Desktop Support Administrator - Cybersecurity
Trinity Cyber pioneered active network defense — preemptive security that surgically removes threats from live traffic before attackers can establish presence on endpoints and networks. While competing Detection & Response approaches demand alert triage and reactive firefighting, our Full Content Inspection™ capability meets adversaries in the network and cleans malicious content from protocols, code, and files in real time — with sub-millisecond inspection latency and near-zero false positives. Every day, we work at scale: protecting over 3 million users and processing 1.5 trillion content objects. As an IT Desktop Support Administrator, you will be responsible for supporting and maintaining the endpoint systems our teams rely on every day. This role focuses primarily on macOS laptops, Windows virtual desktop environments, and company-managed iPhones, while also supporting Linux-based environments as needed. We are looking for someone who combines strong technical troubleshooting ability with operational maturity and a security-first mindset. Due to federal contract requirements, only US citizens will be considered for hire. How We Work:
- Strategic Autonomy: We hire self-directed professionals who can independently manage technical issues, prioritize operational needs, and execute effectively without excessive oversight.
- Security-First Operations: Every system we deploy and maintain must align with the security requirements of a cybersecurity company operating in high-trust environments.
- Operational Discipline: We prioritize stability, repeatability, documentation, and process improvement over improvisation and unnecessary complexity.
- Remote Excellence: Enjoy the flexibility of a 100% remote role while collaborating with a high-caliber team that values technical integrity above all else.
