Join Whatnot, the largest live shopping platform in North America and Europe. As a Senior Software Engineer in the Infrastructure Traffic team, you will own the path between customers and our code, ensuring fast, reliable, and secure connections. This is a hands-on, software-first role that requires deep experience with Istio, Envoy, Kubernetes networking, and modern cloud provider networking. Enjoy flexible work options, generous benefits, and the opportunity to shape the future of commerce.

Missions

  • Shape how traffic reaches the company at the edge, from caching and security posture to the routing decisions that determine how fast the platform feels in each part of the world.
  • Build and scale the private connectivity that carries traffic between services, accounts, and clusters, and keep it secure as the topology grows.
  • Push the service proxy and mesh layer further, tuning it for the traffic patterns and extending it when the off-the-shelf configuration stops being enough.
