Senior Rust C++ Backend Engineer
Reya is a decentralized perpetuals exchange built on Ethereum, offering fast, secure, and permissionless trading of crypto perps, RWA perps, staking, and spot markets. It serves crypto traders seeking CEX-level speed with full self-custody and Ethereum-grade security.
About Reya
Reya positions itself as 'Ethereum for traders,' operating a high-speed perpetuals exchange currently running as an L2 on Arbitrum Orbit, offering zero gas fees, MEV protection, and yield-bearing collateral (srUSD and wstETH). The organization is building 'Reya Evolution,' the first trading venue enshrined in Ethereum L1, using a modular, Ethereum-native stack with based rollup architecture, delegated sequencing, and ZK finality, aiming for millisecond execution and zero maker/taker fees. Reya enables self-custodial trading of perps, spot, staking, and real-world assets (RWAs) in one permissionless venue, targeting traders who want TradFi-level performance without intermediaries. The platform is backed by investors including Framework Ventures, Coinbase Ventures, Fabric Ventures, Amber Group, Wintermute, Selini Capital, Brevan Howard Digital, CMS Holdings, ROBOT Ventures, and Backed VC, and has launched a $REYA token ICO via CoinList.
