About the role
PandaDoc is seeking a Senior Software Engineer to join our Thesis design system team, part of the Core UX area within our Application Platform track. Your work will directly impact how 35+ product teams build UI across the PandaDoc ecosystem and shape the experience for millions of users.
About Core UX
Core UX is the foundational area for PandaDoc's frontend experience. We focus on building platform frameworks, intelligent tooling, and architectural foundations that enable product teams to move faster and build better. The Thesis design system team specifically focuses on:
- Building and maintaining PandaDoc's component library, design tokens, and scalable patterns
- Providing UI primitives that ensure consistency and quality across all products
- Establishing accessibility, performance, and quality standards
- Supporting 35+ product teams with production-grade components, documentation, and modern workflows
Thesis consists of:
- React component library (Thesis UI Kit)
- Figma libraries defining our visual language
- Documentation and guidelines at thesis.pandadoc.com
- Monorepo contains 80+ components across multiple packages (components, icons, themes, utilities), requiring careful dependency management and versioning strategies.
As a Senior Engineer on the Thesis team, you'll architect and build complex components, establish patterns that scale across the organization, and leverage modern tooling—including AI—to accelerate design system adoption and developer productivity. You'll work hands-on building production-grade components while mentoring engineers and driving quality standards across product teams.

- Ensure production-grade quality through comprehensive testing, performance optimization, and thorough documentation
Cross-functional execution
- Collaborate with designers to translate design intent into production-ready components, ensuring visual and functional excellence
- Build intelligent tooling and automation that streamlines repetitive tasks—from component scaffolding to design token synchronization
- Establish feedback loops with designers and product teams to continuously improve component quality and usability
Evangelism
- Drive adoption of Thesis across the organization by supporting engineering teams, improving documentation, and establishing clear usage guidelines
- Champion accessibility standards and best practices, ensuring all components meet WCAG guidelines
- Mentor engineers on component architecture, composition patterns, and design system principles
Innovation
- Stay ahead of industry trends in design systems, frontend development, and AI-assisted workflows
- Leverage GenAI to boost adoption and developer experience—build intelligent agents, migration tools, and automation that help engineers work more efficiently
- Apply prompt engineering and context-aware AI to accelerate development cycles, from component generation to automated migrations
