Your responsibilities include:
- Developing new user-facing features
- Building reusable code and libraries for future use
- Ensuring the technical feasibility of UI/UX designs
- Optimizing applications for maximum speed and scalability
- Translating design in Figma and/or Sketch to reusable components

- Typescript
- web3
- Tailwind CSS

Testimonials
Throughout my efforts of obtaining a position, I spoke with a handful of recruiters and Zoë was the most prompt, efficient, and helpful. She made the negotiation process effortless and helped me land the job!

We’ve worked with many partners on the sourcing side but 3Cubed absolutely stands out from the rest. They have worked tirelessly on our behalf to find the right candidates to fit our very specific (and often challenging) needs while constantly improving the search criteria through an ongoing open communication loop. Very recommended.

I have been so impressed with Helen and Zoe at 3Cubed that they’ve become my “go to” recruiter for our company!! The quality and calibre of their candidates far surpasses the others.
