Position Summary:

The Sr. Staff Network Engineer is the senior technical authority for PacBio’s enterprise, lab, manufacturing, data center, and cloud networks. This individual contributor owns network architecture, long-term reliability, and technical standards across sites; enables high-throughput movement of sequencing data; strengthens segmentation and security for regulated environments; and advances network automation. The role provides technical leadership across IT, Information Security, Engineering, R&D, Manufacturing, Quality, and external partners.

Responsibilities:

• Own the multi-year network roadmap for LAN, WAN/SD-WAN, wireless, data centers, colocation, and cloud connectivity.
• Design resilient, high-throughput network paths from sequencing instruments to on-premises storage and AWS/Azure compute; address capacity and performance bottlenecks.
• Architect data center and colocation networks, including spine-and-leaf designs and redundant LAG/MLAG server, storage, and uplink connectivity.
• Define network standards for hardware, topology, addressing, BGP/OSPF routing, DNS, IPAM, and reference designs.
• Lead hybrid-cloud networking designs, including AWS Direct Connect, Transit Gateway, VPCs, and relevant Azure connectivity.
• Serve as the senior escalation point for complex incidents; lead root-cause analysis, post-incident reviews, observability, availability objectives, and capacity planning.
• Plan network lifecycle refreshes, site and colocation build-outs, and laboratory/data center moves with minimal business disruption.
• Own enterprise Wi‑Fi performance and reliability across corporate, laboratory, and manufacturing facilities, including coverage, capacity, roaming, interference, authentication, monitoring, and wireless optimization.
• Manage the technical performance of ISPs and network carriers, including circuit inventories, utilization, service levels, outage escalations, redundancy, and connectivity improvements; partner with IT leadership on renewals and cost optimization.
• Partner with Information Security on Palo Alto Networks and other firewall policies, network segmentation, NAC/802.1X, and identity-integrated zero-trust access.
• Segment instrument, operational technology, and manufacturing networks; support validated‑system change controls, audits, and ISO/SOX evidence.
• Integrate network and firewall logs with security monitoring and incident investigations.
• Advance network‑as‑code, configuration management, source control, and automated compliance using Python, Ansible, Terraform, and vendor APIs.
• Mentor engineers, review technical designs, assess vendors and MSPs, and communicate technical risks and investments to stakeholders.

Required Qualifications:

• 10+ years of network engineering experience, including 3+ years owning architecture in a multi‑site enterprise.
• Bachelor’s degree in computer science, engineering, a related field, or equivalent practical experience.
• Advanced routing and switching expertise (BGP, OSPF, VLANs, VRFs, LAG/MLAG, spanning tree, QoS) using Cisco, Arista, or Juniper.
• Experience with data center spine‑and‑leaf architecture, EVPN‑VXLAN, colocation cross‑connects, and carrier/cloud interconnects.
• Demonstrated experience troubleshooting enterprise Wi‑Fi performance and managing ISP/carrier services, circuit reliability, and vendor escalations.
• Hands‑on experience with next‑generation firewalls (Palo Alto Networks or Fortinet), VPN, network segmentation, and zero‑trust network access.
