Principal Software Engineer

About the Role

ZoomInfo is looking for a Principal Software Engineer to serve as a senior technical force multiplier across three pillars of our Platform Engineering organization: Integrations, Workflows & Orchestration, and Data Management. Together, these teams own the connectors, orchestration, and data quality capabilities that push ZoomInfo's data product into customer systems.

This is a hands-on, high-impact individual contributor role reporting directly to the Senior Director of Software Engineering and working closely with three Engineering Leaders and their teams.

The Three Pillars You'll Support

• Integrations: Native connectors and APIs linking ZoomInfo to CRM, marketing automation, sales engagement, data warehouse, and BI platforms (Salesforce, HubSpot, Marketo, Outreach, Snowflake, and others), processing millions of records daily.
• Workflows & Orchestration: The engine behind lead-to-account matching and multi-step, event-driven business processes triggered by buying signals and business rules.
• Data Management: Deduplication, standardization, enrichment, continuous verification, and GDPR/CCPA compliance that keep customer data clean, current, and trustworthy.

What You'll Do

• Embed with Integrations, Workflows & Orchestration, and Data Management teams on a rotating basis, writing production-quality code and unblocking the hardest technical problems.
• Define and evolve scalable, fault-tolerant, event-driven architecture on Java/Spring Boot, Node.js/NestJS, Kafka, and workflow orchestration platforms such as Temporal or Google Cloud Workflows.
• Lead response and root-cause analysis for high-severity incidents and systemic reliability issues.
• Drive platform modernization by consolidating integration patterns, re-architecting legacy systems, and improving observability.
• Establish best practices for idempotency, retries, error handling, state management, API and webhook versioning, and workflow design.
• Shape multi-quarter roadmaps with the Senior Director, Engineering Managers, and Product, bringing technical feasibility, sizing, and risk into prioritization.
• Lead build-vs-buy evaluations and author architecture decision records and design docs that guide teams over multiple quarters.
• Mentor engineers at all levels and serve as a senior interviewer to raise the hiring bar.

What You Bring

Must-Have

• 12+ years of software engineering experience, including significant time in senior or staff-level roles, with a track record of technical leadership across multiple teams.
• Deep experience designing and operating backend distributed systems at scale, with strong proficiency in Java (Spring Boot) and/or Node.js (NestJS).
• Experience building or owning integrations or connectors with CRM, marketing automation, sales engagement, or data warehouse platforms (Salesforce, HubSpot, Marketo, Snowflake, or similar).
• Demonstrated ability to influence without authority by aligning teams, driving decisions, and earning trust across engineering, product, and business stakeholders.
• Strong track record leading platform modernization, reliability, and observability initiatives, with excellent written and verbal communication skills, including presenting to executive leadership.

Preferred

• Hands-on experience with event-driven architectures and streaming technologies such as Kafka, and workflow orchestration platforms such as Temporal, Google Cloud Workflows, or Airflow.
• Working knowledge of data quality practices: deduplication, standardization, enrichment, and GDPR/CCPA compliance.
• Experience with API strategy, webhooks, partner/ISV integration programs, and no-code/low-code workflow builders.
• Experience with multi-cloud environments (AWS, GCP), build-vs-buy evaluations, vendor management, and SaaS cost optimization.
