BTQ is a global leader in quantum technology dedicated to enhancing security for mission- critical networks. Operating at the intersection of scientific research and practical applications, BTQ addresses rising cybersecurity challenges by integrating state-of-the-art quantum solutions. By joining BTQ, you will be part of a pioneering team shaping the future of secure communications
Role Description
This is a full-time or part-time hybrid role based in Sydney, NSW, with flexibility for some work- from-home arrangements. You will develop, analyse, and implement cryptographic algorithms, design secure authentication protocols, and contribute to quantum-resilient cryptosystems — working closely with a team of experts across interdisciplinary projects. A key focus of this role is developing quantum cryptographic software as part of BTQ's quantum offense solutions, with particular attention to efficient algorithms designed to run on application-specific neutral atom quantum computers. You will assess and advance the security of one-shot signature schemes under both classical and quantum attack models, and contribute to post-quantum secure communication protocols.
What you'll do
* Develop and implement quantum cryptographic software targeting neutral atom quantum computing architectures
* Design and analyse cryptographic algorithms, secure authentication protocols, and quantum-resilient cryptosystems
* Analyse the cryptographic security of local quantum cryptography protocols (quantum processors + classical communication channels)
* Assess the security of one-shot signature implementations against classical and quantum adversaries
* Design quantum algorithms and post-quantum secure classical communication protocols to augment network security
* Conduct research to address emerging challenges in cryptography and quantum computing
* Collaborate across interdisciplinary teams and communicate findings clearly to the BTQ AU group and broader BTQ Technologies technical team
What we're looking for
* Advanced degree (PhD preferred) in quantum computing, cryptography, mathematics, physics, or a closely related field
* Proficiency in cryptography and cryptanalysis, with a strong understanding of cryptographic algorithms and their practical applications
* Experience with quantum computing concepts and algorithms
* Ability to work collaboratively in a hybrid environment and communicate complex technical results clearly
* Right to work in Australia
Nice to have
* Experience with NIST post-quantum standardisation candidates
* Prior work in quantum-safe protocol design or formal security proofs
* Familiarity with quantum emulation software
* Familiarity with one-shot signatures or related quantum cryptographic primitives
