Senior Site Reliability Engineer, Platform

Posted Updated 4 views
Discussion

We are building a distributed GPU-compute marketplace. Buyers launch GPU workloads and inference deployments. Provider nodes run those workloads through a Go control plane and a Linux-based Rust agent.

We are hiring a senior Site Reliability Engineer to own production reliability as we move from validated paid-path drills to operating a real production fleet.

You will work directly with the CTO and will have broad ownership of production operations, deployment safety, observability, and incident response.

What you will own:

  • Production deployments, rollback plans, and safe database migrations.
  • Monitoring, alerting, dashboards, and operational runbooks.
  • Incident response, post-incident analysis, and permanent reliability improvements.
  • Infrastructure as code, secrets management, access controls, backups, and recovery drills.
  • Reliability of the backend, workers, gateway, databases, and provider-node fleet.
  • Fleet installation and validation for GPU providers.
  • Capacity, availability, and cost visibility for production infrastructure.
  • Engineering automation that removes recurring operational work.

Our stack

  • Go backend services.
  • Rust agent running on Linux GPU hosts.
  • PostgreSQL, Redis, NATS and JetStream.
  • Kubernetes, containers, gVisor, Prometheus, Grafana, and Alertmanager.
  • Terraform and Ansible.
  • GCP and bare-metal GPU infrastructure.

What we need

  • 6+ years operating production infrastructure or distributed systems.
  • Strong Linux and networking troubleshooting skills.
  • Production Kubernetes experience.
  • Experience with Terraform or another infrastructure-as-code system.
  • Experience with Prometheus, Grafana, logs, alerting, and incident response.
  • Experience operating PostgreSQL, Redis, queues, or other stateful production systems.
  • Strong scripting or programming ability in Go, Python, or Bash.
  • A track record of building reliable systems, not only responding to tickets.
  • Clear written communication and comfort owning an incident from detection through prevention.

Nice to have

  • GCP or another major cloud platform.
  • Bare-metal, GPU, NVIDIA, or high-performance-compute operations.
  • mTLS, secrets management, security hardening, or compliance work.
  • Experience with Rust services or agents.
  • Experience supporting a paid, multi-tenant product.

This is a hands-on senior role. You will write automation, improve production systems, participate in on-call, and help shape how our company operates as it grows.
