About the Role

We are building the inline cloud data plane that powers a next-generation AI security platform. This service terminates TLS, inspects and processes enterprise AI traffic in real time, and applies policy, classification, orchestration, auditing, and analytics — at millisecond latencies under production SaaS load across multiple global regions.
We are looking for a hands-on Principal Engineer to own the architecture, design, and implementation of this data plane end to end.

What You’ll Do

Architect and build the inline cloud data plane that processes enterprise AI traffic in real time.
Own the request path end to end: TLS termination, HTTP/2 and HTTP/3 handling, policy evaluation, classification hooks, upstream routing, and response streaming.
Design multi-tenant, multi-region PoP architecture with strict p50 / p95 / p99 latency budgets and availability SLOs.
Design and implement request routing, service discovery, resiliency, timeout, retry, circuit-breaking, and backpressure strategies on the hot path.
Optimize the platform for added latency, throughput,



connection density, TLS handshakes/sec, and cost per million requests.
Drive cost and operational efficiency across the data plane, including capacity planning, autoscaling behavior, infrastructure utilization, and cost per unit of traffic.
Integrate the data plane with policy enforcement, classification, orchestration, auditing, analytics, and other core platform services.
Define the control-plane integration model for configuration distribution, policy propagation, service discovery, tenant isolation, and protected rollout of data-plane changes.
Build distributed tracing, metrics, and end-to-end observability tuned for inline request-path debugging.
Architect Kubernetes-based deployments, horizontal autoscaling, rolling upgrades, and multi-region disaster recovery for the data plane.
Drive technical decisions on proxy technology selection (Envoy vs. custom vs. hybrid), extension model (filters, WASM,
