Network Administrator

CSBio•Milpitas, CA

About The Position

CSBio is a peptide contract manufacturing company founded in 1993. We are looking for a hands-on, multi-faceted IT Infrastructure Specialist to take ownership of the day-to-day technology that keeps CSBio running. This is not a software development role. Instead, we need someone who is genuinely comfortable across the full breadth of small-to-mid-size company IT — from running ethernet through a wall, to programming a managed switch, to walking a new hire through their email setup. The ideal candidate is a generalist who enjoys variety, takes ownership of problems, and can communicate clearly with a workforce that is highly skilled in chemistry and manufacturing. You will be one of the primary points of contact for IT issues across the company, and you will help shape the infrastructure as we continue to grow. CSBio is also in the middle of a digital transformation — moving 200+ paper SOPs, batch records, and lab forms onto a centralized data platform, and layering AI-powered automation on top. This role provides the infrastructure backbone that effort runs on, and supports the day-to-day operations to see it through.

Requirements

2+ years of hands-on IT experience in a small-to-mid-size company environment, with broad exposure across networking, servers, and end-user support
Working knowledge of Windows Server, Active Directory, Group Policy, DNS, and DHCP, Mac and Windows OS
Practical experience with managed switches, VLANs, firewalls, and VPN technologies
Comfort with structured cabling — able to pull, terminate, and test ethernet runs without contracting it out
Familiarity with backup software and strategies for both corporate data and standalone instrument PCs
Strong troubleshooting instincts and the patience to support non-technical users in a respectful, plain-English way
Self-directed; comfortable owning problems from start to finish without close supervision

Nice To Haves

Industry certifications such as CompTIA Network+ / Security+, Cisco CCNA, or Microsoft Server certifications
Prior experience supporting a manufacturing, laboratory, or pharmaceutical/GMP-regulated environment
Experience with virtualization (Hyper-V, VMware) and Microsoft 365 administration
Familiarity with instrument control PCs — not as a chemist, but in terms of keeping the PCs healthy, networked, and backed up
Basic scripting in PowerShell or batch for routine automation (no formal software development required)
Experience supporting ISO 9001 / 21 CFR Part 11 / data-integrity expectations
Interest in or exposure to digital transformation projects — paperless workflows, document management systems, or supporting AI/LLM tooling in a business environment

Responsibilities

Configure, deploy, and troubleshoot site-to-site and client VPN connections
Program and maintain managed network switches (VLANs, port configurations, firmware updates)
Pull, terminate, and test ethernet runs for new lab equipment, workstations, and office build-outs
Maintain wireless infrastructure, including access points, controllers, and guest network segregation
Monitor network performance and proactively address bottlenecks or reliability issues
Administer Windows domain environment, including Active Directory, Group Policy, DNS, and DHCP
Maintain corporate file servers, application servers, and supporting infrastructure (physical and virtual)
Manage user accounts, permissions, security groups, and access controls in line with company policy
Apply patches, updates, and security configurations across servers and endpoints
Implement and verify backup routines for corporate data, file shares, and instrument controller PCs (HPLC, synthesizer, lyophilizer, balance, and similar systems)
Coordinate with QA and manufacturing to ensure backups support data integrity and audit-readiness in a regulated (GMP) environment
Maintain documentation of backup schedules, retention policies, and restoration procedures
Periodically test restores to confirm recoverability
Image, configure, and deploy laptops and desktops for new hires, including domain join, software installation, and user account setup
Install, configure, and troubleshoot networked printers, scanners, and label printers across office and lab areas
Provide responsive, patient helpdesk support to a workforce that is generally not IT-savvy — explaining issues in plain language and resolving recurring pain points
Manage software licensing, device inventory, and asset tagging
Onboard and offboard employees from a technology standpoint
Respond to ad-hoc IT requests from across the company — from “my email isn’t working” to “we need a network drop in the new lab by Friday”
Coordinate with outside vendors for ISP, telecom, copier, and specialized IT services
Maintain documentation of network diagrams, server configurations, vendor contacts, and standard operating procedures
Support facility-related IT projects in coordination with Facilities and Engineering teams
Support on-premise deployment of AI/LLM tooling — hardware setup, GPU/server provisioning, network configuration, and ongoing uptime
Provide end-user troubleshooting as staff transition from paper to digital workflows
Assist with the physical scanning and digitization of paper SOPs, batch records, and lab forms — operating scanners, configuring OCR settings, and ensuring scanned files meet quality and naming standards
