[Remote] Senior Software Engineer, Infrastructure Traffic

Note: The job is a remote job and is open to candidates in USA. Whatnot is hiring an Infrastructure Engineer for its Traffic team, which owns the network path between customers and the company's code. The role focuses on building and operating fast, reliable, and secure traffic infrastructure, improving observability, and automating safe network changes.

Responsibilities

• Shape how traffic reaches us at the edge, from caching and security posture to the routing decisions that determine how fast Whatnot feels in each part of the world
• Build and scale the private connectivity that carries traffic between our services, accounts, and clusters, and keep it secure as the topology grows
• Push our service proxy and mesh layer further, tuning it for the traffic patterns we actually have and extending it when the off-the-shelf configuration stops being enough
• Keep name resolution, TLS, and internal access boring, and automated, to the engineers who depend on them
• Make the network legible. Every layer of a request should be instrumented well enough that "is it the network?" gets answered with evidence in minutes instead of debated for hours
• Design for the failure cases first. Network changes carry enormous blast radius, so you will build tooling that makes correct changes easy and dangerous ones hard, and rehearse failover before we need it

Skills

• Bachelor's degree in Computer Science, a related field, or equivalent practical experience
• 7+ years of professional software engineering experience
• Have deep, hands-on experience (3+ years) with Istio and Envoy. You know the components and configuration surface intimately and have tuned them successfully for very different use cases
• Have written custom Envoy extensions when configuration alone wasn't enough
• Know Kubernetes networking deeply, from CNI behavior and pod and service networking to ingress and how traffic actually moves inside and between clusters
• Have operated a CDN at scale
• Have run globally distributed applications and understand what differs when your users and your infrastructure sit in different regions
• Have owned latency-sensitive systems and can reason precisely about where milliseconds come from and go
• Have strong networking fundamentals across DNS, TLS, TCP, and routing, plus genuine curiosity about the layers beneath the application
• Know modern cloud provider networking deeply, AWS in particular. You have designed VPC topology at scale and understand the tradeoffs between Transit Gateway, PrivateLink, peering, and NAT well enough to pick the right one and defend it
• Debug across boundaries. You are comfortable with packet captures, proxy logs, and traces, and you answer "is it the network?" with data
• Preferably running the network behind high-traffic applications
• Preferably Cloudflare
