Description

The company is building an onchain trading product that is not an exchange. The main work is in the system's design: who gains and who loses, who holds which assets, and how unusual cases are handled.

Responsibilities

  • Take the product from idea to release, covering both the onchain and offchain parts, with frequent releases.
  • Help shape pricing, payouts, rewards, liquidations and tokens.
  • Look for weaknesses in the system before outside attackers do, since funds attract probing within hours of launch.
  • Use AI coding agents daily: guide them, check their output, and decide when to skip them.

Requirements

  • Solid engineering skills and a quick ability to learn.
  • A project you built that people used.
  • Hands-on familiarity with onchain markets, such as trading or using DEXes, bridges and wallets.
  • Interest in mechanism design and incentives.
  • Ownership of your work, including the ability to start without a detailed spec.
  • No particular stack, degree or number of years of experience is required.
