About This Role

You’ll lead the platform’s backend and infrastructure, working directly with the CEO, who currently runs the backend, alongside one growth engineer, one mobile engineer, and a few contractors. This is a full-stack infrastructure role: keeping the platform up, making it faster and more resilient, and building the systems behind new features. The role is in person at the San Francisco office, five days a week.

Scale defines the work. Millions of daily users generate request volume closer to that of a large consumer company than a B2B SaaS business, and infrastructure problems often surface as product bugs: a slow page, a delayed job, or a websocket that keeps reconnecting.

What You’ll Own

  • Build the infrastructure behind new features, including recommendation systems, model fine-tuning, and the inference pipeline
  • Own production reliability through monitoring with Datadog and the logging stack, responding to incidents, and shipping fixes that address root causes
  • Improve performance and resilience across APIs, database queries, caching, background jobs, and real-time connections
  • Continuously harden the existing stack, including bot mitigation
  • Make architecture and capacity decisions as usage grows, and shape how the team deploys, monitors, and recovers

Visa sponsorship is available for O-1, H-1B transfers, and J-1.

Requirements

  • Experience with TypeScript/Node.js and PostgreSQL
  • Experience running backend or infrastructure systems in production
  • Experience taking ownership in a small team
  • Ability to turn vague problems into working solutions
  • Ability to trace a system from the user experience down to the machine
