About The Business Applications Org

The Business Applications org builds and operates the internal systems that help Thumbtack run effectively at scale: Salesforce‑centered workflows, admin tooling, and integrations that connect teams across the company. We are expanding that foundation into a broader internal platform for business workflows, with shared APIs, reusable integration patterns, and safe, auditable capabilities for business‑critical actions. The org works closely with engineering and business partners to turn complex internal needs into systems that are easier to operate, extend, and automate responsibly.

The challenge

Thumbtack's internal systems are becoming more connected, more automated, and more central to how teams serve customers, pros, and the business. Business Applications is helping drive that shift by turning Salesforce‑centered workflows and operational tools into a broader internal platform for AI‑enabled work. The challenge for this engineer is to build the backend services, APIs, and integration patterns that let agents and business systems take safe, auditable action across Thumbtack's internal ecosystem. This work will shape how teams move from one‑off operational workflows to production capabilities that can be reused, extended, and trusted by the business.

What You’ll Do

• Build backend services and APIs that connect Business Applications workflows with Thumbtack's product and platform services.
• Bring agentic and AI‑enabled workflow prototypes into production with the reliability, observability, and human review needed for business‑critical work.
• Create reusable integration patterns that let internal tools, third‑party systems, and agents take safe, auditable action across systems.
• Partner with business and engineering teams to understand operational workflows and turn the highest‑value problems into durable backend capabilities.
• Help define the technical foundation for a BusApps platform that supports reliable integrations, safe automation, and production AI workflows.

In order to be successful, you must bring

• Strong backend engineering experience building production services, APIs, or platform capabilities.
• Technical judgment for integrations where reliability, security, data correctness, and audibility matter.
• Ability to turn ambiguous operational workflows into clear technical designs that can be delivered incrementally.
• Strong collaboration skills with engineering, business, and operational partners, especially when technical constraints and business needs need to be reconciled.
• Comfort learning new domains quickly, including internal systems, third‑party business applications, and AI‑enabled workflows, with the judgment to know when automation needs human review.
