Infrastrucuture Engineer, Traffic

People who do well at Whatnot tend to be comfortable figuring things out as they go, biased toward action, and genuinely curious about what they're building. They care more about outcomes than credit and stay close to the product and the people using it.

Bachelor’s degree in Computer Science, a related field, or equivalent practical experience.

7+ years of professional software engineering experience preferably running the network behind high-traffic applications.

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, preferably Cloudflare

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
