Research Assistant in Lattice and Post-Quantum Cryptography, Centre for Quantum Technologies (NUS)
Job Description
The Computer Science Group of the Centre for Quantum Technologies at NUS is hiring a Research Assistant in cryptography. The work is on the algorithms and computational complexity of lattice problems and their use in cryptography, including post-quantum cryptography: lattice problems underpin most of the new quantum-resistant encryption and signature standards. It is a research role suited to a bachelor’s or master’s graduate who wants hands-on experience before a PhD, and prior lattice or cryptography knowledge is helpful but not essential.

Pay and location
NUS does not publish a salary in this posting; research assistant pay follows NUS scales. There is no closing date in the posting.
How to apply
Apply through the official NUS job posting. NUS’s posting does not give a closing date, so the role is open until filled; ResearchJobs.in will re-check this listing on 14 October 2026. Check the posting for location and work-authorisation details before you apply.

How to prepare for this application
- Learn the basics of LWE, SIS and lattice reduction (LLL, BKZ), and why ML-KEM and ML-DSA rely on them.
- Show a proof or algorithm write-up you did, even from a course project.
- If you have coded any lattice or crypto algorithm, bring it.
- Say whether you are thinking of a PhD afterwards; RA posts are often a stepping stone.
