Come help us build a scalable infrastructure to help millions of users get the right pro’s for all of life’s projects.

  • Design the system and processes that engineers use to deploy their software into production.
  • Design, write, and maintain software to improve the availability, scalability, latency, and efficiency of Thumbtack's services, incorporating third-­party tools (ELK, pgbouncer, ZFS, HAproxy) when available and writing software of your own when nothing else fits the bill.
  • Engage in service capacity planning and demand forecasting, anticipating performance bottlenecks and provisioning new hardware as necessary.
  • Run software performance analysis and system tuning.
  • Plan and execute DiRT.
  • Participate in rotating on-call duties.
