As a Senior Software Engineer on the Integrations team, you'll design and build the systems that connect ZoomInfo's platform to the ecosystem of CRM, MAP, and external eco-systems that our customers depend on. You'll work on highly scalable backend services that power reliable, real-time data sync and API integrations across millions of records — enabling seamless connectivity between ZoomInfo and platforms like Salesforce, HubSpot, and Microsoft Dynamics 365.

You'll leverage technologies like Kafka, Confluent Cloud, Node.js/NestJS, and modern API and authentication standards to build resilient, observable, and fault-tolerant integration services. Your work will be foundational to how ZoomInfo's data reaches customers and connects with the tools at the center of their go-to-market stack.

Our engineering culture values diversity, intellectual curiosity, problem-solving, and openness. We encourage collaboration, big thinking, and calculated risk-taking in a blame-free environment. You'll have the autonomy to work on meaningful projects while receiving the support and mentorship needed to grow your career.
