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 secure 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
