Cloud Network Engineer

Position Overview

the company is at an inflection point. We just launched the company Celeste — our agentic AI platform built for the world's top law, accounting, private capital, and professional services firms. More than 2,700 firms globally rely on our platform, and we're re-architecting everything around AI-native workflows. The Cloud Platform Engineering (CPE) team sits right at the center of that.

This is a cloud networking role at its core. We're expanding into new cloud regions and standing up many more Kubernetes clusters, and we need someone who can design the network — and the network security — that holds it all together across Azure and AWS, for regulated, compliance-heavy clients who can't afford surprises. A big part of the job is designing network security for agentic workloads: how AI agents are isolated, what they're allowed to reach, and how every connection stays governed and auditable.

This isn't a keep-the-lights-on role: we want engineers who use AI as a force multiplier in their own work, and there's real scope to shape what secure, multi-region cloud networking looks like as Celeste scales. You'll work closely with the Kubernetes team, with shared services and overlapping responsibilities.

• Architect and operate the Azure and AWS network as we expand into new regions.
• Design network security for agentic workloads — isolation, segmentation, and egress control.
• Build cluster networking for a fast-growing Kubernetes fleet.
• Define network infrastructure as code with Terraform.
• Support and harden Azure Entra n and authentication.
• Use AI for anomaly detection, alerting, and automated runbooks.
• Partner with the Kubernetes and product engineering teams.
• Lead deep dives on complex networking issues.

• 2+ years on Azure (AWS a plus), with cloud networking as a core strength.
• Deep networking fundamentals — DNS, routing, firewalls, segmentation, and VNet/VPC.
• Experience designing cloud network security and zero-trust controls.
• Hands-on Kubernetes networking — CNI, ingress/egress, and network policies.
• Identity and authentication experience, such as Azure Entra  / AD.
• Comfortable using AI tooling in an engineering or operations context.
• Automation-first — you write it, not just read it.

• Scaling networks across multiple regions or a large Kubernetes fleet.
• Service mesh — Istio, Linkerd, or Cilium — and east-west policy control.
• AWS networking alongside Azure.
• Prometheus, Grafana, or similar observability tooling.
• Securing AI, ML, or agentic workloads at the network layer.
