kraken.com - Mobile UI/Design Engineer

• Deep, demonstrable experience building polished mobile interfaces in React Native — you know Reanimated well, you've fought with gesture handlers, and you've profiled JS thread vs UI thread performance and won • A trained eye for interaction design — you notice when an easing curve is wrong, you have opinions about spring physics, and you understand that 60fps isn't a target, it's a constraint • A portfolio or demo reel of shipped work is a hard requirement — a personal site, video walkthrough, GitHub interaction demos, or screen captures of work you're proud of. If we can't see your craft, we can't evaluate it • Experience with modern AI development tooling (Cursor, Copilot, or similar) as a natural part of how you build — not as a novelty, but as a multiplier • Strong written and verbal communication skills in English • Experience with React Native Skia, custom shader work, or canvas-based rendering for non-standard UI • Some native platform knowledge (Swift/Kotlin) for when you need to drop below the RN abstraction — bridging, native modules, platform-specific behaviour • You've built interaction patterns that other engineers adopted — shared animation libraries, gesture primitives, motion design systems • Background in or affinity for visual/motion design — maybe you prototype in Figma or After Effects before you write code, maybe you sketch interaction flows on paper. Either way, you think visually • Experience in high-stakes product domains (fintech, health, trading) where UI precision affects user trust • Strong opinions, loosely held — you push back on designs that won't translate well to mobile and advocate for the user's experience, but you also know when to ship and iterate • Unless a specific application deadline is stated in the job posting, applications are accepted on an ongoing basis. • Please note, applicants are permitted to redact or remove information on their resume that identifies age, date of birth, or dates of attendance at or graduation from an educational institution. • We consider qualified applicants with criminal histories for employment on our team, assessing candidates in a manner consistent with the requirements of the San Francisco Fair Chance Ordinance. • Kraken is powered by people from around the world and we celebrate all Krakenites for their diverse talents, backgrounds, contributions and unique perspectives.
