Senior Full-Stack Engineer

Arx Research is a small team focused on building hardware and protocols for enabling authentic physical crypto assets, IRL token gating and radically simple self-custody.

The core team has worked on secure hardware for over a decade and created the technology behind KONG Cash, Offline Cash and the PBT (physically backed token). Arx Research has supplied projects like Azuki, Poolsuite, CabinDAO and Metafactory with tens of thousands of secure chips to date.

In conjunction with new hardware, we’re working on an open protocol bridging secure chips with manufacturers, brands and end users – the Ethereum Reality Service or ERS.

While we have an incredible amount to build, we’re focused on doing so with a very small, agile team. You'll need to work independently which means the confidence to choose the right technology to build with, structure your projects, understand when you need code review.

You are:

• Hungry to build and ship fast
• Someone who has built your own web3 projects, top to bottom including smart contracts and frontends
• Language agnostic, but likely with experience in with Solidity, Vyper or another smart contracting language as well as Typescript and Javascript
• Comfortable with a framework like React, Angular, Nextjs
• Comfortable with Ethers.js, web3.js or Viem
• Someone who has good understanding of smart contracts and core Ethereum standards like ERC721 and ERC20

Bonus Skills

• You've written your own EIP
• You’ve worked for an early stage startup before and enjoy the independence to ship quickly
• Open source contributions and library creation experience
