Simplyblock builds Kubernetes-native, software-defined NVMe-over-Fabrics block storage. Our customers run it underneath databases and stateful workloads where downtime is measured in money and latency is measured in microseconds.

When something behaves oddly in a large multi-tier distributed storage cluster, the customer talks to you. You are the person who turns a vague symptom into a reproducible root cause, a fix, and a change that keeps it from recurring.

This is not a ticket-queue job. You sit between our customers and our engineering team, you own the analysis end to end, and you have a direct hand in how the product evolves.

What you'll do
- Analyse complex operational and software issues in a large multi-tier distributed system — data path, control plane, cluster state, and the Kubernetes layer around it.
- Own customer communication. Respond to incidents, guide customers through upgrades and migrations, and answer advanced product, architecture, and tuning questions.
- Go deep on root cause. Logs, metrics, traces, core dumps, packet captures,



reproductions — whatever it takes to explain the behaviour rather than describe it.
- Coordinate resolution across engineering. Bring the pieces together from storage, networking, control plane, and platform teams, and keep momentum until the issue is genuinely closed.
- Push proactively for improvements. Permanent fixes over workarounds, better observability, better defaults, and automation that reduces both the number of incidents and the manual operations effort.
- Turn what you learn into assets — runbooks, diagnostic tooling, product feedback, and documentation the next engineer doesn't have to rediscover.

What you bring
- Networking engineering depth. TCP/IP internals, RDMA/RoCE, congestion and flow control, multipathing, MTU and offload issues — you can read a capture and tell a story with it.
- Distributed systems experience in production. A real feel for failure modes: partitions, split brain, quorum loss,
