Senior Systems Engineer
About The Position
People 1st IT is looking for an experienced Level 3 Engineer / Senior Systems Engineer to join our technical team. This is a senior technical role focused primarily on project implementation, infrastructure improvements, migrations, advanced troubleshooting, and technical escalations within a managed services environment. The ideal candidate is comfortable taking ownership of complex technical projects from planning through implementation, working directly with clients, coordinating with vendors, documenting environments, and serving as an escalation resource for other technicians. People 1st IT Inc. is a San Francisco-based managed IT services provider serving small and mid-sized businesses throughout the greater Bay Area — including Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco counties. For nearly three decades, the company has served as a trusted technology partner across industries such as construction, law, financial services, real estate, and manufacturing, taking a proactive, relationship-driven approach rather than a reactive, ticket-based model. Its services span network administration, dedicated virtual CIO partnership, 24/7 centralized monitoring, and professional support, alongside cloud computing, cybersecurity, disaster recovery, and phone systems — all backed by a hands-on, on-site presence that complements its remote monitoring capabilities.

- Firewalls, switches, VLANs, VPNs, and wireless networking, including Ubiquiti / UniFi environments.
- VOIP systems, backup and disaster recovery platforms, and remote monitoring and management platforms.
- MSP documentation and ticketing systems, and domain, DNS, SSL, and certificate management.
- Strong troubleshooting skills across servers, cloud platforms, networks, and endpoints.
