Network Engineer

Quick Facts

• Role: Network Engineer (in-house)

• Focus: Designing and operating a global, cloud-scale network for multiple data-center locations

Description

We are building a global, cloud-scale network to support growing software products. This role brings network operations in-house and focuses on designing networks for existing and new data-center locations (software and hardware) while optimizing connectivity, stability, and performance across transit providers and Internet exchanges.

Responsibilities

• Design and evolve networks for existing and new data-center locations, spanning both software and hardware

• Help guide hardware purchases toward strong price-to-performance outcomes

• Establish and optimize peering relationships with Tier 1 transit providers, Internet exchanges, and other network operators

• Monitor network stability, prevent and mitigate abuse, and optimize transit costs

• Participate in hardware installations and resolve real-world deployment issues

• Provide on-call coverage for network-related issues and incident management

Requirements

• Operated networks at scale (Tbps throughput, thousands of physical servers or more)

• Connected networks to Internet exchanges (IXs) and established private peering

• Mitigated DDoS attacks multiple times

• Proficient with Arista and Dell gear (or can quickly adapt to any hardware)

• Strong knowledge of BGP, ECMP, BFD, VRRP, VLANs, LACP, MLAG, VXLAN/EVPN, IPv6, DNS64/NAT64, CoPP, RPKI, OVN, WireGuard, GRE, QoS, MTU, conntrack, and Linux networking

• Understands packet flow through switches, routers, hypervisors, and virtual machines; can troubleshoot at every layer

• Completed zero-downtime live migrations

• Sysadmin or engineering background

• Clear, confident English communication (writing and conversation)

• Async-first, meeting-averse style; comfortable using Slack, Notion, Loom, and e-mail

• Infrastructure as code is a default approach

Benefits

• Work with a distributed team building network infrastructure for cloud-scale products across multiple time zones

• Lead in-house network management and support network incident response as the environment scales

• Fast-moving, engineering-focused culture with asynchronous collaboration
