About SpareBrains

SpareBrains helps small and medium-sized businesses run better. A team of people and AI agents does real work for them. It finds where they’re losing customers online, fixes it, and keeps it running week after week. Our agents work inside our clients’ own accounts and tools, always with the owner’s approval. That makes trust the heart of what we sell.

The role

Our agents work inside real business accounts, every day. You’ll build and run their platform, so it stays up, keeps each client separate and leaves a full audit trail. You’ll set up how we deploy, watch and recover, from the start.

What you’ll do

Run the platform

  • Host and scale our agents, queues and scheduled jobs.
  • Keep each client’s work and data separate.
  • Keep a complete audit log of every agent action.

Reliability

  • Set reliability targets, alerts and safe rollouts.
  • Lead on-call, and write clear reviews after incidents.
  • Plan backups and recovery, and test them.

Infrastructure

  • Manage infrastructure as code, and our build and deploy pipelines.
  • Set up logs, metrics and traces across the system.
  • Keep cloud costs in check.

What you’ll bring

  • 4+ years in infrastructure, platform or site reliability engineering.
  • A major cloud provider, Terraform and containers.
  • Monitoring and tracing in production.
  • Real on-call experience.
  • You can explain how TLS works beyond the buzzwords.

You don’t need every item on this list. If the work excites you, apply anyway.

Nice to have

  • Telephony or WebRTC infrastructure.
  • Serving AI models.
  • SOC 2 environments.
  • Setting up reliability practice from scratch.

What we offer

A competitive base salary, equity, and the chance to build SpareBrains from its first day.
