Description

About us Bitget Wallet is the non-custodial crypto wallet designed to make crypto simple and secure for everyone. With over 80 million users, we bring together a full suite of crypto services, including swaps, market insights, staking, rewards, DApp exploration, and payment solutions. Supporting 130+ blockchains and millions of tokens, Bitget Wallet enables seamless multi-chain trading across hundreds of DEXs and cross-chain bridges. Backed by a $300+ million user protection fund, it ensures the highest level of security for users' assets. What you'll do Design and develop the core backend modules of our DEX, including:• Swap (AMM) matching, single-chain & cross-chain transactions, and limit-order matching engine• In-house aggregator for routing, quotation, and optimal path computation Help architect and implement backend services that meet high-availability, high-concurrency, and high-scalability standards. Integrate deeply with EVM/Solana smart contracts: build on-chain interaction logic, listen to and parse on-chain events, and ensure data consistency between on-chain and off-chain systems. Optimize the performance and security of the trading pipeline; continuously monitor and improve TPS, latency, fault tolerance, and risk-control capability. Collaborate closely with product, frontend, smart-contract, and DevOps teams to drive rapid iteration and deliver high-quality products. Participate in code reviews, technical sharing, documentation, and best-practice development
