About the Engineering team

At Thumbtack, engineers at every level build products and systems that directly impact our customers and professionals. Our challenges span a wide variety of areas, ranging from building search and booking experiences, to optimizing pricing systems, to building tools to help professionals grow their businesses. We believe in tackling these hard problems together as a team, with strong values around collaboration, ownership and transparency. To read more about the hard problems that our team is taking on, visit our engineering blog.

This team sits at the intersection of platform and product engineering. The challenge is twofold:

Scale & Reliability: Our services must handle high traffic and core application logic while meeting strict uptime and latency expectations.

Enablement: We must also empower other product teams with reusable libraries, frameworks, and patterns that accelerate their development while maintaining consistency and sustainability across Thumbtack’s Go-based ecosystem.

You’ll be tasked with evolving core services that underpin Thumbtack’s growth while enabling engineers company-wide to move faster with confidence.

What you'll do

• Design, build, and maintain resilient backend services that provide core application capabilities (e.g., identity, media, delivery/communication).
• Develop and maintain reusable libraries and frameworks for logging, monitoring, storage access, and service-to-service communication.
• Partner with product and platform teams to design APIs and distributed systems patterns that are reliable, efficient, and easy to integrate.
• Anticipate scaling challenges through capacity planning and proactive engineering.
• Participate in the team’s on‑call rotation, ensuring services meet defined SLAs and addressing production issues.

In order to be successful, you must bring

• 5+ years of experience in backend or systems engineering roles, with exposure to high‑scale production environments.
• Proficiency in a backend language such as but not limited to Go, Python, or PHP to build highly available APIs and distributed systems.
• Strong knowledge of AWS and Linux.
• Experience designing, operating, and troubleshooting services that handle critical user‑facing traffic.
• Solid understanding of databases, caching, and messaging systems (e.g., DynamoDB, Postgres, Redis, Kafka, or equivalents).
• Proven ability to collaborate across teams, balancing product velocity with long‑term service health.
• Experience working on platforms that create leveraged software for the entire engineering organization to use and build on top of.
