Reflexer Labs

Low volatility collateral for DeFi

Backend Javascript & Web3 Developer

Who we are

Reflexer Labs is building RAI the “reflex bond”, a volatility-dampened synthetic instrument backed by ETH. We are decentralized money fanatics on a mission to create a stable and secure foundation for the Ethereum DeFi ecosystem. Our objective for RAI is to be a widely used collateral type for other DeFi projects, including crypto-dollars. By imbuing RAI with autonomy and minimizing governance, we aspire to build a financial system that outlives us—a money god.

Who you are

Reflexer Labs is a tiny new startup, so we’re looking for someone who’s willing to get their hands dirty and occasionally go above and beyond what their job description says on paper. Our ideal candidate is:

  • Money-positive
  • DeFi enthusiast, familiar with MakerDAO
  • Independent, organized, and accountable
  • Security-minded
  • A team player

  • 5+ years professional dev experience
