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 to raise overall team productivity and technical standards.

What you’ll need

Bachelor’s degree or above in Computer Science, Software Engineering, or a related field.
3+ years of backend development experience, with 1+ years of hands-on Golang; familiar with Gin, gRPC, Etcd, etc.
At least one project involving Dapp or smart-contract interaction on EVM or Solana; deep understanding of contract invocation, transaction lifecycle, nonce & gas mechanisms.
Solid knowledge of AMM principles (e.g., Uniswap v2/v3, Curve, Balancer) and common aggregator path-optimization algorithms.
Proficient in backend fundamentals such as microservices, message queues, caching, and databases:• Middleware: Redis/Memcache, Kafka/RabbitMQ• Databases: MySQL/PostgreSQL plus at least one NoSQL (MongoDB/ClickHouse, etc.)• Container & DevOps: Docker, Kubernetes, CI/CD
Strong grasp of data structures, algorithms, and concurrent programming; able to diagnose performance bottlenecks in high-concurrency scenarios independently.
Excellent system design, documentation, communication, and self-learning skills.
