Senior Network Engineer

What success looks like in this role:

Provide Network Engineering support for all network segments and applications.

Act as L2/3 escalation for P1/P2 incidents; lead triage stabilization and post-incident RCA with clear corrective actions.

Troubleshoot advanced routing switching wireless firewall load balancing and VPN issues across multi-vendor environments.

Optimize performance (QoS congestion control path selection) and reduce chronic incident recurrence.

Design and implement high-availability network architectures (redundant core/edge SD-WAN data center fabrics segmentation).

Own changes from design review through implementation and validation aligning with GxP/GMP change control and documentation.

Enforce network security baselines (micro-segmentation NAC firewall policies IDS/IPS secure VPN certificate management).

Collaborate with InfoSec on risk assessments hardening and compensating controls.

Manage and optimize connectivity to public cloud (Azure/AWS): ExpressRoute/Direct Connect hybrid routing private endpoints.

Support SD-WAN policy design traffic steering and cloud edge security integration.

Maintain robust observability (SNMP flow telemetry synthetic tests packet captures logs NPM/APM tools).

o Utilize NPM tools (e.g. SolarWinds ThousandEyes) packet capture (Wireshark) NetFlow/sFlow/IPFIX syslog/SIEM or similar tools

Build automation for configuration compliance and repeatable changes (e.g. Ansible/Netmiko/Python) including templating and guardrails.

Author and maintain network standards runbooks validated configurations and diagrams (as-built/target state).

Execute ITIL processes (Incident Problem Change Configuration Management) with precise records suitable for audits.

Mentor L1/L2 engineers; provide technical guidance and training.

Partner with OT Lab IT Manufacturing Application and Security teams to deliver solutions aligned to business and regulatory needs.

Ability to rack/stack equipment and work in data center/lab/manufacturing areas with appropriate PPE.

Work with cross-functional teams to design solutions for expanding connectivity while maintaining overall network performance and integrity.
