Software Engineer - Platform Integrations

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.

What You Will Do:

• Design, build, and maintain scalable backend services using Node.js (NestJS). Java (Spring Boot) is a plus
• Develop and manage our platform integrations layer, handling connectivity, data ingestion, and exports between ZoomInfo’s data layer and third-party integrations
• Design systems for reliable job execution, retries, state management, and long-running processes
• Implement orchestration patterns for complex, multi-step business processes
• Design and maintain APIs and internal services that integrate with external systems
• Build observability into systems (logging, tracing, metrics) to monitor integration health and performance
• Ensure high availability, fault tolerance, and scalability of backend systems handling large volumes of events
• Optimize system performance, throughput, and latency across distributed systems
• Troubleshoot and resolve production issues in complex, asynchronous systems
• Lead medium to large-scale feature development, working independently while coordinating with cross-functional teams
• Collaborate with product and platform teams to define integration requirements and execution guarantees (SLAs/SLOs)
• Participate in agile development processes, sprint planning, and technical discussions
• Provide technical mentorship and conduct thorough code reviews to elevate team capabilities
• Stay current with emerging technologies and evaluate new tools for potential adoption
• Support production systems through monitoring, troubleshooting, and reliability improvements

• Bachelor’s degree in Computer Science, related field, or equivalent experience
• 5+ years of software engineering experience with a focus on backend systems
• Strong experience with Java (Spring Boot) and/or Node.js (NestJS)
• Experience building integrations with CRM or MAP platforms such as Salesforce, HubSpot, or Microsoft Dynamics 365
• Familiarity with no-code/low-code integration platforms (e.g., Fivetran, Zapier, or similar)
• Solid understanding of authentication and authorization protocols including OAuth 2.0, OIDC, SAML, and JWT
• Experience with third-party API patterns - rate limiting, pagination, error handling, and data transformation pipelines
• Proficiency with MongoDB and comfort working across relational and NoSQL data stores
• Experience designing and implementing RESTful and webhook-based APIs with strong grasp of versioning, reliability, and backward compatibility
• Solid understanding of software architecture patterns, cloud platforms, databases, and distributed systems concepts
• Proven experience with performance optimization, security best practices, and scalable system design
• Demonstrated ability to write clean, maintainable, production-quality code and conduct effective code reviews
• Strong problem-solving skills with the ability to debug complex technical issues and implement robust solutions
• Excellent communication skills for collaborating with technical and non-technical stakeholders
• Experience with agile development methodologies, version control systems, and CI/CD practices
