ZoomInfo Technologies LLC
ZoomInfo is where careers accelerate. We move fast, think boldly, and empower you to do the best work of your life. You’ll be surrounded by teammates who care deeply, challenge each other, and celebrate wins. With tools that amplify your impact and a culture that backs your ambition, you won’t just contribute. You’ll make things happen–fast.
About the Role:
We are seeking an experienced Principal Software Engineer to lead the design and development of ZoomInfo’s customer-facing GraphQL API platform, built on top of our industry-leading Go-to-Market (GTM) data assets.
You will be a technical anchor for a collaborative engineering team, setting architectural direction for how enterprise customers and partners programmatically access the world’s most comprehensive B2B intelligence. This is a high-impact individual contributor leadership role where your decisions directly shape platform quality, scalability, and customer success.
What You’ll Do:
– Architect, design, and own the end-to-end development of ZoomInfo’s customer-facing GraphQL APIs, ensuring high availability, low latency, and developer-friendly experiences.
– Define schema design standards, versioning, deprecation, and backward-compatible evolution across product surfaces.
– Work with product managers and data engineers to expose ZoomInfo’s GTM data assets (BigTable, BigQuery, Solr) through well-structured, queryable API surfaces.
– Implement and enforce API security, OAuth 2.0, JWT, RBAC, rate limiting, and query complexity controls.
– Maintain production reliability through CI/CD pipelines (Jenkins, ArgoCD) and observability practices using Datadog.
– Use AI tooling (Claude, GitHub Copilot) as part of your daily workflow and help the team do the same responsibly.
– Lead code and design reviews, mentor senior engineers, and contribute to the engineering roadmap.
What you bring:
– Deep GraphQL expertise: schema design, resolvers, federation, subscriptions, and performance optimization. Experience with GraphQL Yoga or Apollo Server (transferable skills).
– Strong Node.js and TypeScript skills for API services and developer tooling; Go experience for backend and infrastructure work.
– Experience securing customer-facing APIs, OAuth 2.0, JWT, fine-grained authorization, rate limiting.
– Familiarity with large-scale data systems; exposure to BigTable, BigQuery, or Solr is a plus.
– Experience building developer-facing SDKs or API tooling. You think about the API consumer, not just the implementation.
– Familiarity with AI coding tools (Claude, GitHub Copilot); experience with AI Agents or MCP tooling is a bonus.
– Clear communicator who can drive technical decisions and bring along both engineering and non-engineering stakeholders.
Ideal Background:
– 8+ years of software engineering experience, with a focus on production-grade, customer-facing APIs at scale.
– Prior experience owning a developer-facing API platform at a SaaS or data company.
– Bachelor’s or advanced degree in Computer Science, Engineering, or a related field.
