Location: On site in Austin, TX (5 days to start, will work to only 3 days eventually)
Team:

• Working in the Network Infrastructure Services Org

Day to day:

• Focus on IP/Ethernet configuration of various elements (e.g, servers, switches, router, ACLs) but not the main task. This is needed only to get us going when building a testbed and gluing things together.
• Testing automation, able to do networking configuration, connectivity, transport protocols, troubleshooting with e.g, iperf, Wireshark, speed test.

Skills:

• Strong Linux networking.
• Strong android / adb skills to configure phones & features, extract performance, metrics - Understanding of transport protocols, specifically TCP, QUIC.
• Familiarity with test tools in the lab (e.g, iperf, Wireshark, speed test) to either troubleshoot E2E testbed or to extract results during test execution.
• Good understanding of E2E network and configuration (including cellular or wifi) from networking perspective.
• Working in lab environment, hacky approach.
• Testing automation.
• Capable of putting testbed together in a lab environment.

Scope of work: Network Design and Architecture:

• Develop and implement network designs that align with the organization's infrastructure requirements and business objectives.
• Design resilient and scalable network architectures to support current and future needs.
• Evaluate and recommend network technologies and solutions to enhance performance and efficiency.

Network Implementation and Configuration:

• Deploy and configure network devices such as routers, switches, firewalls, and load balancers.
• Implement network protocols and services including TCP/IP, VLANs, OSPF, BGP, VPNs, and QoS.
• Conduct network testing and troubleshooting to ensure proper functionality and performance.

Infrastructure Integration:

• Collaborate with infrastructure teams to integrate network components with server, storage, and virtualization systems.
• Ensure seamless communication and interoperability between network and infrastructure elements.
• Participate in infrastructure projects to provide networking expertise and support.

Network Security:

• Implement and maintain network security measures to protect against unauthorized access, threats, and vulnerabilities.
• Configure and manage security appliances such as firewalls, intrusion detection/prevention systems, and VPN gateways.
• Monitor network traffic for suspicious activity and respond to security incidents as necessary.

Performance Monitoring and Optimization:

• Monitor network performance and analyze traffic patterns to identify bottlenecks and optimize resource utilization.
• Conduct capacity planning to anticipate future network growth and requirements.
• Implement performance tuning strategies to improve network efficiency and responsiveness.

Documentation and Compliance:

• Create and maintain documentation for network designs, configurations, and procedures.
• Ensure compliance with regulatory requirements and industry standards related to network infrastructure and security.
• Participate in audits and assessments to validate network compliance and adherence to policies.
• Collaboration to ensure the reliability and security of the organization's network environment.

Root cause network issues (IP, DNS, DHCP) impacting reliability of network services to end customers.

• Leverage experience in IPv4 and IPv6 networking, L2/L3 network protocols (spanning-tree, OSPF, BGP), TCP/IP, DHCP, DNS, VLAN, VRRP, LACP, MC-LAG, EVPN with VXLAN, ACL to address issues.
• Leverage understanding of Unix, Linux systems and ability to modify scripts in Python, bash, scripting.
• Take packet captures and working with WireShark to root cause network related issues.
