About the company

Our client is a consumer technology company.

The role

Raydar is recruiting for this role on behalf of our client. Lead backend and infrastructure work for a high-traffic consumer web platform, keeping services dependable and quick while building the systems behind new features. You will diagnose issues from the user-facing symptom to the root cause and own technical decisions on a very small team.

What you'll do

  • Build the infrastructure that supports new product features, including recommendation, model training and serving pipelines.
  • Own production reliability through monitoring, logging, incident response and fixes that remove root causes.
  • Tune the speed and fault tolerance of the API layer, data access, caching, asynchronous processing and live connections.
  • Keep strengthening the existing stack, including protection against automated abuse.
  • Make architecture and capacity decisions as usage grows, and shape how the team deploys, observes and recovers services.

What we're looking for

  • At least 4 years of software engineering experience, with a meaningful share spent on backend or infrastructure systems.
  • Experience running significant backend systems in production, beyond writing the code.
  • Strong skills in TypeScript/Node.js and PostgreSQL.
  • Versatile enough to debug across multiple layers of a system, even in areas that are new to you.
  • Comfort taking an ambiguous problem to a production fix with little direction on a small, high-ownership team.
  • Able to work on-site 5 days a week.

Bonus points

  • Experience with NestJS, Redis or Kubernetes.
  • Background in distributed systems or GPU infrastructure.

Benefits

  • Health, dental and vision coverage

Location and work model

  • San Francisco, CA, United States
  • On-site, 5 days a week in office
  • Full-time

Compensation, as the posting describes it

  • Retirement plan with employer match
