Job description

Design and evolve low-latency, highly resilient network architecture across global data center, co-location, and cloud-connected environments, with a focus on deterministic packetforwarding, scalability, and operational consistency
Lead advanced routing design and implementation across complex global environments, including BGP, OSPF, MPLS, multicast, hybrid cloud connectivity, traffic engineering, and high-availability network patterns
Conduct deep technical research, lab validation, and pre-implementation testing for major network initiatives, working closely with engineering and software development teams to evaluate hardware capabilities,identifydesign constraints, and optimize exchange performance based on findings
Lead high-complexity strategic projects from design through execution, producing detailed technical designs, migration runbooks, capacity plans, and implementation guidance for large-scale network changes
Develop andmaintainPython-based network automation to support configuration management, change validation, testing, and operational efficiency, with direct experience using both API-driven and SSH-based automation approaches
Partner across infrastructure, security, application, and business teams to align network design and delivery with technical requirements, operational goals, and broader organizational priorities, including support for budgeting and planning related to network hardware and software investments
Contribute to monitoring and telemetry strategy by helping define meaningful visibility requirements and supporting the use of tools such as Prometheus, Grafana, or similar platforms where they improve operational insight and troubleshooting

Requirements

10+ years of hands-on network engineering experience in mission-critical, low-latency environments, with a strongtrack recordoperating and evolving high-performance network infrastructure
Deepexpertisein low-latency and deterministic network design, including practical experience analyzing latency, jitter, and end-to-end traffic behavior in production environments
Advanced knowledge of routing protocols at scale, including BGP, OSPF, MPLS, and multicast (PIM-SM/SSM), with proven experience designing resilient,highly availableglobal networks
Strong understanding of network hardware and platform capabilities across major vendors, with the ability to evaluate limitations and optimize design decisions through hands-on research and lab validation
Experience designing and supporting hybrid cloud connectivity, including AWS networking constructs such as Direct Connect, Transit Gateway, VPCs, and route integration
Proven experience building andmaintainingPython-based network automation, including API-driven and SSH-based approaches for configuration management, testing, and operational efficiency
Working knowledge of observability and telemetry concepts, with exposure to platforms such as Prometheus, Grafana, or similar tools for network visibility and performance analysis
Strong background in leading technical research, proof-of-concept validation, and pre-implementation design for large-scale network initiatives
Solid understanding of network security fundamentals, including segmentation, access control, and zero-trust principles as they apply to network design
