The Role

Collectors is the leading creator of innovative technology that provides value-added services for collectors worldwide. We grade, authenticate, vault, and sell millions of record-setting collectibles, all while modernizing and digitalizing the process to further our mission of helping collectors pursue their passions. We’re always on the lookout for talented people to join our growing team.

Our services span collectible coins, trading cards, Funko Pops!, video games, event tickets, autographs, and memorabilia. Our subsidiaries include PSA, PCGS, SGC, WATA, and Card Ladder.

Since our founding in 1986, we have graded and authenticated millions of items. We employ more than 1,900 people across our headquarters in Santa Ana and offices in Jersey City, Tokyo, Shanghai, Hong Kong, Toronto, Guadalajara, Dallas, and Paris.

Role Overview

We are looking for a Senior UX Engineer to join our team of designers who can design polished UI and write production Flutter and/or React code. The ideal candidate should have a deep passion for front-end development, design, and craft, and be energized in a fast-paced environment.

You'll be working on products like the PSA App (available on the App Store and Google Play), which helps collectors identify & price, track, manage and list their trading card collections. This is a unique opportunity to shape intuitive, delightful experiences for a passionate and global community of collectors.

What You’ll Do:

As a mobile design engineer at Collectors, you will report to the director of design and partner with the design, product, and engineering team to bring joy and craft into our mobile experiences. 

  • Partner with the design and research teams to quickly build prototypes to test concepts internally and externally.

  • Establish, evolve, and maintain design foundations, systems, and patterns for the team, setting the bar for quality and consistency. 

  • Collaborate with design, product, and engineering to light up craft and delight into our production mobile experiences.

  • Work with and mentor feature engineers on design best practices, and help unblock designs or interactions within a specific feature.

What We’re Looking For:

Above all we’re looking for someone who deeply cares about craft, polish, and delight in user experiences - and has work, whether side projects or company projects, to back it up with. 

  • 3+ years of React or Flutter experience (Flutter preferred) 

  • Skills and understanding of good product design (layout, padding, type, color).

  • Perfectionism and obsession in the work you ship, getting every detail right.

  • Experience working closely with a design and a product team.

  • Someone who is energized by close collaboration, and is proactive to a fault.

  • Experience building and maintaining a design system, and evangelizing the systems across teams. 

  • Examples of highly polished side projects, whether shipped or simply concepted.

  • Can reduce complex problems down to simple design solutions.

  • A passion for collecting is a plus. 

Salary Range: The salary range for this position is $135,549 - $220,067. Actual compensation on this range varies based on a variety of non-discriminatory factors, including location, job level, prior experience, and skill set. This role may be eligible for bonuses, commissions, or other forms of compensation, please ask your recruiter for details.

This role can be remote or based in any of our offices.
