This senior network engineering role focuses on the design, implementation, and ongoing operation of robust Layer 3/Layer 4 network services. The position spans both data center environments and cloud infrastructures. You will have the autonomy to own projects from inception to completion, actively contributing to the development of network standards and enhancing system reliability through automation and advanced observability techniques. Collaboration is key, involving close work with your immediate team and adjacent SRE, platform, and security groups to achieve impactful outcomes in availability, performance, and operational efficiency. This role also involves peer mentorship, applying proven methodologies, and proposing innovative solutions to elevate existing systems and processes.

- Design and implement L3/L4 network topologies, including IP addressing, routing policies (BGP, OSPF, IS-IS), EVPN/VXLAN fabrics, and SDN overlays across data centers and cloud platforms. - Configure and manage cloud networking constructs like VPC/VNet, subnets, routing tables, NAT, and secure connectivity solutions. - Implement network security controls, including segmentation, ACLs, encryption, and DDoS/WAF integrations, adhering to zero-trust principles. - Develop and maintain automation tools such as Terraform and Ansible for network provisioning and configuration management. - Integrate network changes into CI/CD pipelines with a focus on policy-as-code and automated testing. - Implement and operationalize monitoring solutions using telemetry, NetFlow, and flow logs for comprehensive visibility. - Define and track Service Level Indicators/Objectives (SLIs/SLOs) and establish proactive alerting and runbooks. - Collaborate with SRE, platform, and security teams on architecture, incident response, and capacity planning. - Participate in on-call rotations and contribute to root-cause analysis and problem management. - Produce detailed design documentation, diagrams, and operational runbooks. - Conduct and participate in design and change reviews, contributing to reference architectures and reusable modules.

This role is for an experienced Senior Network Engineer. While specific educational degrees are not detailed, a strong foundation in network engineering principles is essential.
