This is a unique opportunity to help define the UX of privacy in Web3 and shape how users interact with next-gen decentralized systems
Design, implement, and maintain front-end applications for zk-powered tools and dApps
Initial projects in the first months will be designing and developing the frontends for our showcase payment dApp and sequencer staking bootstrap projects, critical for our mainnet launch this year
Work closely with product managers to align UI/UX with product requirements. Work closely with engineers to integrate aztec.js into the apps and provide critical feedback

Our take

Aztec is working to bring real privacy to the world of DeFi, using Ethereum-based zero-knowledge rollups that compress data to keep transactions private. With Aztec, users can interact with popular DeFi apps without broadcasting their activity to the whole blockchain (offering a rare bit of discretion in a space that's usually wide open).

There’s been a lot of discussion about Crypto privacy of late. Supporters deem it essential, while sceptics suggest that malicious actors might abuse their privacy. Indeed, Aztec has had to recently overcome some difficulty when popular exchange FTX blocked accounts that were linked to the protocol.

However, if cryptocurrencies are to become mainstream – and maintain their safety – it seems that better privacy will be required, which puts Aztec in a good position to become an important player in the industry. And funding raised in 2024 will definitely help the company in achieving its lofty aims.
