Why Join Us:
At BIT, we tackle complex problems as a team. We encourage openness and promote transparency, respect, and inclusivity. Every team member is valued and has a voice that can be heard. We are always in search of intellectually curious and entrepreneurial individuals who are keen on making an impact in the crypto ecosystem and in building a better product for the next one billion users.
Job Responsibilities:
Analyse how mainstream blockchain protocols work (Ethereum/EVM, Cosmos SDK, Substrate, Solana, etc.) and help redesign wallet systems based on secure cryptographic mechanisms.
Develop hardening and mitigation plans against known protocol-level vulnerabilities and emerging risks.
Contribute to the security-driven re-architecture of existing systems, including defence-in-depth for critical modules and clear trust boundaries.
Write, debug, and test code for secure, high-performance systems under the guidance of senior engineers.
Track emerging blockchain attack techniques and defences, and turn research into shippable improvements.
Participate in security audits of internal systems and open-source dependencies, and drive remediation.
Collaborate with cross-functional teams, document technical work, and share knowledge through design docs, code reviews, and tech talks.
Take on ad-hoc technical tasks and projects as assigned.
Job Requirements
Fresh graduate or up to 2 years of work experience, with a degree in Computer Science, Cryptography, Cyber Security, Engineering, Mathematics, or a related field. Master's degree preferred.
Strong command of at least one of Java, Go, Rust, or C++. Python is a bonus.
Solid foundation in data structures, algorithms, distributed systems, and concurrency.
Familiarity with threat modelling, secure coding, penetration testing, and supply-chain security.
A "zero trust" security mindset, with the ability to turn ambiguous requirements into clear technical designs.
Strong analytical skills, eager to learn, and comfortable in a fast-paced environment.
Good communication and teamwork skills, and able to communicate in both English and Mandarin.
Internship, research, or project experience (e.g. CTFs, open-source, blockchain projects) is a plus.
