[远程] Cryptape 招聘**底层研发工程师/Rust Software Engineer

About Cryptape

Cryptape is a pioneering team in the blockchain space, leading the development of Nervos CKB (Common Knowledge Base) — a high-performance, scalable Layer 1 blockchain protocol. We are committed to pushing the boundaries of decentralized systems through rigorous engineering and open collaboration. If you're passionate about low-level technical challenges and building future-facing wjkn, we invite you to join the CKB engineering team at Cryptape.

As a member of the CKB engineering team, you’ll contribute to core system development, such as network protocol b,ڶ*' ( Fiber ), virtual machines ( CKB-VM ), and smart contract tooling on CKB. We welcome engineers from diverse backgrounds — embedded systems, algorithm b,ڶ*', multimedia codecs, CPU architecture, and beyond. Prior blockchain experience is not required, but a strong interest in systems programming and a willingness to learn are essential.

E){"n)b'

- Develop and implement core ~ܶ*'jX of the Nervos CKB protocol.

- Write and optimize smart contracts in Rust, leveraging CKB’s unique Cell model for flexible state management.

- Optimize low-level code performance, focusing on resource efficiency and execution in constrained z{⮉z{l.

- Collaborate with the global open-source developer community to evolve the CKB ecosystem.

- Write clean, maintainable code and participate in high-standard code reviews.
