• Our remote-first, highly collaborative team offers the flexibility to work from anywhere. We’re committed to supporting your professional growth while respecting and valuing the diverse perspectives each team member brings to the table.

Some Things You'll Do:

• Build and refine robust web applications that simplify complex data-driven interactions into seamless user experiences.
• Work closely with Product Managers, Designers, and Backend Engineers to implement features that enhance our product's functionality and user satisfaction.
• Spearhead the adoption of cutting-edge frontend technologies and advocate for best practices in frontend architecture.

• Passion for pushing the boundaries of web technologies to create the best possible user experience.
• An AI-forward mindset: You’re excited by how AI is reshaping software development and actively integrate AI tools into your workflow to prototype, iterate, and ship smarter and faster.
• It would be great if you had expertise in frontend performance testing and optimization techniques, but we won’t be too greedy!
