​

This is developed to address and solve liquidity fragmentation and the complex user experiences across chains, providing a seamless, unified solution for DeFi users and developers alike.Being the world’s first vertical agnostic infrastructure stack, Symphony enables anyone to execute anything across all chains and protocols without being burdened by bridges, multiple wallets, gas fees, etc.

Our team is composed of former Consensys, MetaMask, Kraken, and Axelar veterans, and we’re backed by top investors.

We are looking for an innovative, passionate, and productive person who is excited about building the future of accessible crypto applications, feels comfortable challenging opinions, and most importantly who shares with us the same desire to make DeFi useable again.

​

  • Opportunity. We believe DeFi should be fast AND accessible. You’ll do high-impact work to enhance scalability, shaping the future of crypto
  • Flexibility. We are a remote-first company, and collaborate synchronously and asynchronously, via daily all-hands meetings
  • Culture. As an early member of our team, you’ll have a unique opportunity to help shape our culture. We value intellectual honesty, bias towards action, and believe every member plays a key role in achieving our ambitious goals
