Principal Software Development Engineer, Design Systems (Web)

About the team

Zillow Experience Design (ZxD) shapes how people discover, buy, sell, and rent homes. Within ZxD, Design Foundations creates and scales the systems, standards, and tools that help product teams build high-quality, consistent, and accessible experiences across Zillow.

Design Foundations brings together design systems, digital accessibility, brand and visual language, content standards, and the AI-enabled tools increasingly used by Product, Design, and Engineering teams to design and build products.

Zillow’s design systems, known internally as Constellation, span Web, iOS, Android, and Email. They give teams the shared components, patterns, and guidance they need to build with greater consistency, accessibility, and efficiency.

About the role

We’re hiring a Principal Software Development Engineer to be the technical owner of Constellation Web. You’ll set the technical direction for how the system evolves and keep it a healthy, reliable foundation for more than 300 codebases across Zillow, Trulia, StreetEasy, and HotPads, ultimately shaping how millions of people experience these products.

Zillow is accelerating AI-native product development. Your work will shape how Constellation Web evolves to support AI-assisted development and AI-generated UI, while setting and upholding a high bar for quality, performance, and accessibility across every team that builds with it.

You’ll partner closely with design systems designers and engineers for web, engineering leads for our iOS, Android, and Email design systems, Zillow’s front-end platform team, and senior engineering leaders across Zillow.

Set technical direction for Constellation Web

Define and drive the technical vision for Constellation Web, from component architecture and styling to framework upgrades and future major releases.

Make the consequential architecture decisions that shape how teams across Zillow build for the web, using evidence to bring clarity to complex trade-offs.

Partner proactively with Zillow’s front-end platform team to shape how both platforms evolve together particularly as AI changes front-end development.

Drive adoption and alignment across Zillow

Align senior engineering leaders on foundational technical shifts that require changes across their teams, building buy-in through a clear narrative and shaping investment decisions.

Guide how consuming teams adopt and upgrade Constellation Web across different tech stacks and app architectures.

Build strong partnerships with design systems designers, product managers, engineers, and partner teams to influence initiatives early.

Set and uphold the engineering bar

Own Constellation Web’s performance end to end, diagnosing issues across complex pages built from many sub-apps and micro frontends and driving resolution with the right team.

Own release safety, code quality, and accessibility standards across Constellation Web’s published packages, contributing code where it creates the most leverage.

Mentor senior engineers and grow technical leadership across the team, so knowledge and quality never depend on any one person.

Evolve Constellation Web for AI-native development

Define how Constellation Web is built and used with coding agents while holding the same quality bar, partnering with Constellation’s design technologists.

Shape how the system supports AI-generated and server-driven UI so generated experiences follow the same standards.
