We are looking for a bright and ambitious Postdoc to join PQShield's R&D team, focusing on advancing post-quantum secure messaging. This 2-year position, preferably starting before July 1st, 2024 , offers the opportunity to contribute to exciting research in Tokyo, Japan or Paris, France. While physical presence in these locations is preferred for collaboration with our researchers, remote work arrangements can be negotiated. What you’ll be doing: The primary responsibility of this position will be to advance the state of post-quantum secure messaging such as Signal and Message Layer Security (MLS). While the main focus is to conduct groundbreaking research, we encourage and support translating academic research into tangible contributions, such as proposals to the Internet Engineering Task Force (IETF) for standardisation. Qualifications: While you will mostly collaborate with a group, it is preferred that you have some of the following backgrounds to ensure a smooth start into the project: Previous involvement with secure protocols are helpful to better understand the open problems posed by post-quantum secure messaging. Ability to conduct formal security proofs and to propose new security models are important to handle a complex protocol such as secure messaging. A general knowledge of lattice-based cryptography is preferred to understanding the pros/cons compared to classical cryptography. In addition to cryptographic expertise, we seek candidates with: Previous experience working with diverse teams on projects that cover various cryptographic fields. PhD qualified in Cryptography. Strong communication and presentation skills. The ability to work both independently and collaboratively within a diverse team.
