- As a Staff Engineer, you will lead complex technical initiatives that span multiple teams and systems. You will help define architectural direction, establish engineering standards, improve developer workflows, and guide the evolution of our front-end platform and design system. You will also play a key role in mentoring engineers, influencing technical strategy, and accelerating engineering effectiveness across the organization
- Drive front-end architecture decisions across the platform
- Design scalable, maintainable, and reusable UI systems and application patterns
- Lead large cross-functional initiatives involving multiple engineering teams
- Identify and reduce technical debt across shared front-end infrastructure

- Partner with Design to improve consistency and usability across the product
- Help shape the long-term technical vision for the front-end platform
- Improve shared tooling, component systems, and developer workflows
- Drive improvements in CI/CD pipelines, testing strategy, local development experience, and review environments
- Build reusable frameworks and abstractions that accelerate feature development across teams
- Collaborate on front-end performance optimization and platform-wide UX improvements
- Help standardize approaches across teams while balancing flexibility and autonomy
- Contribute hands-on production code in React and TypeScript
- Review code and provide high-quality technical feedback
- Collaborate closely with Product Managers, Designers, and Engineers throughout the development lifecycle
- Participate in technical planning, roadmap discussions, and architecture reviews
- Help unblock teams and provide technical guidance for complex implementation challenges
- Mentor engineers across multiple teams
- Raise the engineering bar through technical leadership and collaboration
- Influence engineering culture, review quality, and development practices
- Act as a trusted technical partner for both engineering and product leadership
- Help grow future technical leaders and architects within the organization
- Our Front-End Stack
- React
- TypeScript
- GraphQL
- GitLab
- AWS
- Modern CI/CD pipelines
- Design systems and shared component libraries
- What Success Looks Like
- Engineering teams can move faster because of the systems and foundations you build
- Front-end experiences become more scalable, consistent, and maintainable
- Architectural decisions improve long-term product velocity
- Shared standards and tooling reduce friction across teams
- Engineers across the organization seek your guidance for complex technical challenges
- You help shape the future direction of the platform, not just individual features
Application process
- In any materials you submit, you may redact or remove age-identifying information such as age, date of birth, or dates of school attendance or graduation. You will not be penalized for redacting or removing this information
