Hiring trends we’re seeing for 2025
Fault‑tolerance goes mainstream. One in three adverts now references surface codes, syndrome decoding or logical qubits.
Cryo‑electronics talent is scarce. Roles demanding sub‑4 K RF design & cryo‑CMOS command 25 % salary premiums.
Hybrid workflows dominate. Employers expect Python + C++ + QASM plus familiarity with GPU simulators.
Quantum‑safe security spikes. Banks, telcos & MoD units all list PQC or QKD skills; clearance premiums up to 30 %.
Most roles are still on‑site. Two to three lab days per week is standard, though algorithm & consulting posts often remain remote‑first.
How to maximise your applications
Tailor your CV – quantify gate fidelity improvements, compilation speed‑ups or optimisation cost savings.
Use our filters – search “cryogenic + Oxford”, “LLQ + remote”, or “quantum‑safe + contract” on QuantumComputingJobs.co.uk.
Set a job alert – we’ll email you as soon as the Hotlist is refreshed (next edition: October 2025).
Network smartly – attend events like Quantum Tech London, NQCC Industry Day, Q‑Hack UK & the EPSRC Quantum CDT Showcase; many employers above sponsor & interview on‑site.
Upskill continuously – master stabiliser codes, variational algorithms, quantum‑aware profiling tools & PQC standards to stay in demand.
