(IDQ), part of IonQ, is a global leader in quantum-safe communications. We provide solutions to protect governments, telecommunication infrastructures, and banking & financial institutions from the  harvest-now, decrypt-later  threat, delivering both terrestrial and space‑based quantum-safe networks in live operation globally.

We are looking for a Distinguished Leader to provide the overall technical leadership for our post‑quantum cryptography (PQC) hardware acceleration programme, part of our quantum‑safe product portfolio targeting hardware security module (HSM) and network‑appliance applications. As the most senior technical authority of the programme, you will own the end‑to‑end architecture, from cryptographic algorithm and standards strategy to an FPGA‑based product architecture with a clear path to ASIC, and you will set the technical direction across the cryptography, hardware, software and security disciplines involved.

This is a rare opportunity to shape a strategic security product line at one of the few companies where quantum‑safe security is the core business.

You will define the system architecture and microarchitecture of a multi‑algorithm PQC accelerator implementing ML‑KEM, ML‑DSA and SLH‑DSA/LMS: hardware/firmware partitioning, throughput and lane sizing derived from real customer traffic models, and a stable core‑interface specification that lets cryptographic cores evolve behind a frozen contract. You will own the algorithm and standards strategy (NIST FIPS 203/204/205, CNSA 2.0, FIPS 140‑3), drive make/buy and IP‑licensing decisions, and shape the security and certification architecture together with our side‑channel and compliance specialists.

You will set the technical roadmap, arbitrate the hardest cross‑domain design decisions, mentor the senior engineers who own each domain, and represent the…
