Distributed Software Engineer

Engg; Toronto; On-site; CAD 140,000 - 210,000; Full time

Job summary

Cerebras Systems is seeking a seasoned cluster engineer to join the team responsible for turning thousands of wafers, servers, and switches into a reliable, observable cloud. The role focuses on automating bare-metal provisioning, upgrades, and security patches, with a strong emphasis on CRDs, controllers, and RBAC in a Go/Python/Kubernetes stack.

You will design and operate large inference workloads, build telemetry pipelines with Prometheus and Grafana, and contribute to resilient,

Qualifications

• 5+ years building and operating production distributed systems or infrastructure software.
• Production-quality Go and Python.
• Real Kubernetes depth: controllers, CRDs, RBAC, and reconciliation semantics.
• Strong debugging skills across distributed systems, Linux, and networking.
• Prometheus and Grafana experience; metrics and exporter design.

Responsibilities

• Declarative, CRD-driven automation of bare-metal networking, OS, and application software across clusters of Cerebras systems, servers, and switches, built to reconcile thousands of nodes.
• Push-button cluster install, upgrade, and security patching with real downtime budgets, gated by canaries.
• Kubernetes operators that schedule large inference workloads: resource locks, priority queues, topology placement, health-aware placement.
• gRPC control-plane services, authorization, admission webhooks, and quota policy for a multi-tenant fleet.
• Metrics and log pipelines with exporters for wafer-scale systems, servers, and network fabric on Prometheus and Grafana, with SLOs and alerting.
• Failure detection, HA control planes, and automated recovery, plus the CLIs, APIs, and MCP gateway that expose the fleet to users, operators, and AI agents.

Job description

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. This architecture allows Cerebras to deliver industry-leading training and inference speeds; over 10 times faster than GPU-based hyperscale cloud inference services. This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real-time iteration and increasing intelligence via additional agentic computation. Cerebras works with the leading model labs, global enterprises, and cutting-edge AI-native startups. OpenAI recently announced a multi-year partnership https://openai.com/index/cerebras-partnership/ with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference.

The Role The Cluster engineering team owns the software that turns thousands of wafers, servers, and switches into a cloud that stays up, stays busy, and stays debuggable. We stand clusters up from bare metal, schedule training and inference workloads across the fleet, keep it healthy, and make it observable to users, operators, and increasingly to AI agents. The stack is Go and Python on Kubernetes, running both on-premise deployments and our own cloud.

Responsibilities

• Declarative, CRD-driven automation of bare-metal networking, OS, and application software across clusters of Cerebras systems, servers, and switches, built to reconcile thousands of nodes
• Push-button cluster install, upgrade, and security patching with real downtime budgets, gated by canaries
• Kubernetes operators that schedule large inference workload: resource locks, priority queues, network topology, and health-aware placement
• gRPC control-plane services, authorization, admission webhooks, and quota policy for a multi-tenant fleet
• Metrics and log pipelines with purpose-built exporters for wafer-scale systems, servers (Redfish, IPMI), and network fabric (gNMI, sFlow), on Prometheus and Grafana, with SLOs and alerting
• Failure detection, HA control planes, and automated recovery, plus the CLIs, APIs, and MCP gateway that expose the fleet to users, operators, and AI agents

Skills and Qualifications

• 5+ years building and operating production distributed systems or infrastructure software
• Production-quality Go and Python
• Real Kubernetes depth: you have written or debugged controllers and operators, and you understand CRDs, reconciliation semantics, informer caches, admission webhooks, and RBAC
• Strong debugging skills across distributed systems, Linux, and networking
• Prometheus and Grafana as a practitioner: PromQL, exporter design, cardinality discipline, useful alerts
• Strong self-driving capability. This environment is large, fast-moving, and not fully documented, so we need engineers who build their own context, decide, and drive work across team boundaries. Learning speed matters more here than familiarity with our stack.
• Demonstrated adoption of AI in your engineering workflow: active use of coding agents, a view on where they help and where they mislead, and the rigor to verify what they produce.
• Nice to have: bare-metal or HPC fleet operations, scheduler internals, RDMA/RoCE and eBPF networking, Ceph or NVMe-oF, etcd and HA upgrades, inference serving stacks. ML research experience is not required.
