Challenge

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.
