Senior Network Engineer

About the Role
We are seeking a Senior Network Engineer to lead the design, implementation, and operation of high-performance network infrastructure across large-scale data center and cloud environments. This role is critical to ensuring the reliability, scalability, and efficiency of our network systems, while also shaping the future of our network architecture.

You will operate as a key technical leader, partnering closely with infrastructure, platform, and systems teams to support mission-critical services and drive network strategy at scale.

What You’ll Do

• Lead the design, deployment, and operation of large-scale network infrastructure across data center and cloud environments
• Own critical network systems, ensuring high availability, performance, and scalability
• Drive architecture decisions across routing, switching, and overlay networking (e.g., VXLAN, EVPN)
• Troubleshoot and resolve complex, cross-layer network issues impacting production systems
• Develop and implement automation and tooling to improve reliability, observability, and operational efficiency
• Establish and evolve network design standards, best practices, and operational processes
• Partner cross-functionally to deliver end-to-end infrastructure solutions
• Mentor junior engineers and elevate the overall technical capability of the team
• Participate in on-call rotation while improving systems to reduce operational burden over time

Minimum Qualifications

• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent experience)
• 8–10+ years of network engineering experience in large-scale environments (ISP, cloud, or similar)
• Deep expertise in network operations and production support at scale
• Strong understanding of core networking protocols (BGP, OSPF, IS-IS, MPLS, TCP/IP, IPv4/IPv6)
• Proven experience owning and operating critical network infrastructure
• Strong problem-solving skills and ability to lead through complex technical challenges
• Participate in an on-call rotation to support production systems

Preferred Qualifications

• Experience with high-performance networking technologies such as InfiniBand or RoCE
• Strong knowledge of VXLAN, EVPN, and modern data center networking architectures
• Experience with automation and scripting (Python or equivalent)
• Familiarity with network observability, telemetry, and monitoring systems
• Experience with network modeling and programmability (YANG, OpenConfig, NETCONF)
• Experience working with cloud networking and hybrid infrastructure environments
• Strong communication and collaboration skills, with the ability to influence technical direction

What We’re Looking For

• A technical leader who can design and operate networks at scale
• A systems thinker who understands the interaction between networking, compute, and applications
• Someone who takes ownership of critical infrastructure and drives improvements proactively
• A pragmatic engineer who balances reliability, performance, and speed in production environments
• A mentor who raises the bar for the team
