Site Reliability Engineer, Traffic Infrastructure

As a Site Reliability Engineer in the R&D Infrastructure department in our Tel Aviv Office, you’ll own the path every request takes before it reaches a service: The CDN edge, the anycast VIPs behind it, a large fleet of open source load balancers and service mesh components. At peak that chain carries millions requests per second on the way to serving tens of billions of recommendations a day. We need a networking specialist who doesn’t stop at the wire. You bring in depth networking knowledge, native Linux fluency and modern coding practices with the diagnostic intuition to debug complex interactions between BGP enabled nodes, reverse proxies and application logs. To thrive in this role, you’ll need: 5+ years running production organization with internet-facing traffic infrastructure at very large scale, with deep understanding of TCP/IP stack (BGP, anycast, ECMP, DNS-based traffic steering, TCP, TLS, HTTP/2 and HTTP/3). Deep hands-on ownership of L7 proxies in production: Nginx, HAProxy or Envoy/Istio, covering configuration at scale, performance tuning and the class of bugs that only appear under real load. Production experience with a commercial CDN such as Fastly, Cloudflare, Akamai or CloudFront, including edge logic, cache policy and origin protection. Fluency in Linux networking internals and packet-level diagnosis: tcpdump, conntrack, nftables/iptables, socket and TCP tuning. Coding ability that goes past scripting. You will be building tooling and not only editing configuration files. Kubernetes networking depth covering CNI internals, kube-proxy, ingress and east-west traffic policy. Bonus points if you have: A background in traffic observability, whether flow telemetry, real-user monitoring or synthetic probing across regions. How you’ll make an impact: Own the full path a request takes from user to service: CDN configuration, TLS termination, load-balancing policy and failover behavior. Move our proxy and CDN configuration into code with review, testing and staged rollout replacing hand edits in production. Lead the cross-layer investigations nobody else can close from an anycast withdrawal down to a single misbehaving upstream. Plan capacity and drain procedures for the traffic tier so that losing a POP or an entire data center stays invisible to users. Take part in the on-call rotation, lead incident response and turn post-mortems into permanent fixes in the traffic layer. Why Taboola?
