## Description

We are expanding our technical operations in Neenah and seeking a skilled Systems Engineer Sr to join our growing team. This is a hybrid role; candidates should be local to the Neenah area and able to work onsite at least three days per week to foster collaboration and support our hybrid infrastructure.

The Systems Engineer Sr will use and demonstrate the Plexus core values to provide technical support to the Plexus user community while ensuring that cloud applications, systems, and network technologies are available and functioning in support of business processes. This role is central to the "Cloud Engineering" model, treating the network as software to accelerate delivery cycles and leverage Infrastructure-as-Code (IaC) expertise.
Collaboration and Strategy

To deliver and maintain secure, reliable, and sustainable technology solutions, the Systems Engineer Sr will collaborate with Networking personnel, Security/Compliance teams, and business partners. This role operates with a clear demarcation point at the Cloud Router/SD-WAN interface, providing "single-pane" ownership of the VPC environment to reduce handoff latency and improve deployment speed.
Key Job Accountabilities

Cloud Network Infrastructure Lead: Owns the end-to-end lifecycle of networking-including VPC architecture, Shared VPC management, and Cloud DNS-leveraging Terraform and IaC pipelines to automate routing logic and security controls.

Infrastructure as Code (IaC) Authority: Acts as the Accountable/Responsible party for Terraform/IaC development, review, and pipeline execution for all cloud constructs.

Security & Compliance: Implements cloud Firewall rules, IAM policies, and VPC Service Controls to ensure workloads meet project requirements..

Workload Orchestration: Manages the full lifecycle of VMs, GKE (Google Kubernetes Engine) clusters, and Google Distributed Cloud (GDC) at the edge.

Cloud Routing Logic: Responsible for Policy-Based Routing (PBR) logic and internal appliance routing within the cloud project environment.

Systems Design: Produces detailed design specifications and uses modeling techniques (such as Open Policy Agent or custom IaC scanning) to build system components following agreed architectures and design standards.

Incident & Performance Management: Investigates escalated, non-routine, and high-impact incidents, seeking resolution and ensuring proper documentation, root cause analysis, and closure.
