Engagement

Remote · Full-time / long-term. 40 hours / week. BST (UTC+1) core hours — expect meaningful overlap with the UK / BST team during the workday.

About the role

You will own the public ZyncSwap interface: trading screens, wallet connect, transaction feedback, and the marketing site that has to match the product’s pre-launch honesty. ZyncSwap is still in development — this is production frontend work on a product that is not live trading yet.

Nice to have

  • WalletConnect or injected-wallet experience.
  • Trading or fintech UI background.
  • Design-system or accessibility work.

Compensation
