Cryptography Engineer (Multiple positions)
PQShield Ltd.
PQShield Ltd. is a University of Oxford spin-out specialising in Post-Quantum Cryptography (PQC). As an active participant in NIST PQC standardisation process, our mission is to provide industry-leading implementations and solutions for transition from current standard cryptography to quantum-resistant algorithms.

We invite established Cryptography Engineers to join our development team. Candidates are expected to have a minimum of 3 years of experience in designing, implementing (production quality code), evaluating, and benchmarking various types of cryptosystems (i.e. public and symmetric key algorithms and cryptographic protocols).

You are not afraid to learn new mathematical concepts and have instincts for solid security engineering and elegant architectural design. Since our work is groundbreaking in many ways, our engineering roles require an inquisitive and creative mind (textbooks on post-quantum cryptographic engineering are yet to be written). Enthusiastic and skilful computer programmers are welcome and we encourage new research.

Experience with cryptographic libraries (e.g. OpenSSL and derivatives) is essential. Skills related to systems programming (Rust, C), network programming, mobile and embedded systems (ARM, RISC-V), hardware-software codesign (Verilog, VHDL), and even web application frameworks are beneficial.

The company is offering very competitive packages (including share option scheme, relocation, private health insurance, etc.).

To apply, please send your CV to jobs (at)

Multiple vacancies are available and deadline for applications is 7th of August 2019.
