Thumbtack is looking for a Senior Backend Software Engineer to join their Business Applications team to build scalable backend tooling and infrastructure that powers their frontline sales and service, commercial operations, and trust & safety organizations.

Requirements

  • 4+ years experience in backend engineering, with experience building microservice architectures and online services.
  • Experience building and maintaining integration frameworks, middleware, or service layers that connect enterprise SaaS business tools (e.g., Salesforce, Zendesk, contact center platforms) to backend systems.
  • Fluent in at least one major programming language (Go, Python, Java, or similar) and are able to work with multiple coding languages.
  • You have experience building software using databases (e.g. Postgres, DynamoDB, etc.).
  • Experience developing event-driven architectures, messaging systems, or workflow engines.
  • Track record of working cross-functionally with infra, product, and business teams to deliver scalable systems.
  • Hands-on experience building and operating services in cloud environments (e.g. AWS, GCP, Azure) with secure service entry points, managing authentication/authorization, and implementing scalability and resiliency patterns.

Responsibilities

  • This is a hands-on role that will require a high level of autonomy in their work and the ability to make decisions as the founding Engineer supporting the Business Applications team.
  • Unlock and expand write-based and read-based integrations with our product systems (e.g., via GraphQL, APIs) for real-time data pulls.
  • In the near term, building out a microservices architecture to allow Business Application tools to be integrated with product services.
  • Longer term, expanding the existing event-based integrations framework for Salesforce and other 3rd-Party tools into a more scalable, BusApps-owned architecture.
  • Partner with Commercial Operations and Trust & Safety to deliver backend infrastructure for campaigning, alerting, and automation.
  • Collaborate with relevant AI/ML teams to unlock automation and LLM-driven workflows, powering initiatives like Conversational AI.
  • Contribute to backend best practices — service architecture, event-driven systems, monitoring, and resiliency — to scale internal tools into a cohesive platform.
