Job Description & How to Apply Below
Location: Greater London
Keep an agent swarm that runs continuous, sandboxed offensive testing fast, isolated, and always on.
Every Cyrion engagement spins up isolated sandbox replicas, coordinates dozens of concurrent agents, and streams results in real time. You will own the infrastructure that makes that safe and reliable at scale.
What you'll do- Operate and harden the Kubernetes infrastructure running agent workloads and sandbox replicas.
- Build strong tenant isolation guarantees between customer engagements — this is a security product; infra security is not optional.
- Own on-call rotation, incident response, and postmortems for the platform.
- Improve observability (tracing, metrics, logging) across a highly concurrent, agent-driven system.
- Drive cost and performance optimization across compute-heavy scanning workloads.
- 4+ years in SRE/infrastructure roles operating production Kubernetes at scale.
- Strong grasp of network and workload isolation (name spaces, gVisor/Firecracker-style sandboxing, or similar).
- Experience with IaC (Terraform or similar) and CI/CD pipelines.
- Experience operating security or compliance-sensitive infrastructure (SOC 2 / ISO 27001 environments)
Competitive salary plus meaningful early equity, full health coverage, a $2,000/yr learning budget, and your choice of hardware.
