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.

Search Principal Software Engineer Jobs in MarylandPrincipal Software Engineer Jobs in Maryland: Frequently Asked Questions
Which companies sponsor visas for principal software engineers in Maryland?
Federal contractors and defense technology firms are among the most active sponsors for principal software engineers in Maryland. Companies like Booz Allen Hamilton, Leidos, Northrop Grumman, and SAIC regularly hire at the principal level and have established visa sponsorship infrastructure. Cybersecurity firms in the Baltimore-Washington corridor and healthcare technology companies headquartered in Bethesda and Rockville also sponsor at this seniority level.
Which visa types are most common for principal software engineer roles in Maryland?
The H-1B visa is the most common visa category for principal software engineers in Maryland, given the role's specialty occupation requirements and the volume of large employers in the state with established sponsorship programs. Some candidates, particularly those with exceptional records of technical leadership or publications, may also qualify for the O-1A. Candidates already holding TN visa status from Canada or Mexico may find Maryland employers open to that pathway as well.
Which cities in Maryland have the most principal software engineer sponsorship jobs?
Bethesda and Rockville in Montgomery County generate the highest concentration of principal software engineer sponsorship opportunities, driven by federal agencies, NIH-adjacent health tech companies, and large consulting firms. Columbia in Howard County is a secondary hub with a mix of defense contractors and enterprise software companies. Baltimore itself has a growing presence, particularly in cybersecurity and financial technology, with Johns Hopkins-affiliated tech roles contributing to demand.
How to find principal software engineer visa sponsorship jobs in Maryland?
Migrate Mate is built specifically for international candidates seeking visa sponsorship, and you can filter directly for principal software engineer roles in Maryland. This cuts through the noise of job listings that don't sponsor, focusing your search on employers who have demonstrated sponsorship history at senior engineering levels. Given the competition for these roles in the Baltimore-Washington corridor, filtering by sponsorship from the start saves significant time.
Are there any Maryland-specific considerations for principal software engineers seeking visa sponsorship?
A significant portion of Maryland's technology employers work on federal contracts, and many of those roles require security clearances. H-1B visa holders are generally eligible to apply for clearances, but the process can be lengthy and not all employers will initiate it for candidates without existing clearance. Principal-level roles at non-defense companies in biotech and fintech do not typically carry this constraint, making them more accessible for international candidates early in their Maryland job search.
What is the prevailing wage for sponsored principal software engineer jobs in Maryland?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
