Senior Electronic Engineer

ID Quantique (IDQ) as part of IONQ, is a global leader in quantum-safe communications and quantum detection systems. 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. Our Quantum Detection Systems push the limits of single-photon detection, powering breakthroughs in quantum communication, sensing, computing, and ultra-sensitive imaging in partnership with top researchers and tech innovators worldwide.

What to Expect

We are seeking a Senior Electronics Engineer to join our R&D department in Geneva. The successful candidate will take technical ownership of high-performance electronic subsystems that accurately drive and read out ultra-sensitive, fast opto-electronic modules (e.g., lasers, SPADs, interferometers). This is a hands-on role spanning architecture, schematic/PCB design, bring-up, and verification, with a strong emphasis on analog, RF/high-speed, and mixed-signal design to enable robust, industrial-grade products.

What You'll be Doing

You will be responsible for developing complex electronic hardware from early prototypes to industrialised modules, including low-noise amplification, high-speed/RF signal conditioning, drivers for opto-electronic components, A/D conversion, and optimised power-supply blocks. A key part of the role is designing high-performance, low-noise mixed-signal PCBs, applying robust partitioning, grounding, shielding, and layout techniques to preserve signal integrity and minimise coupling. You will define and review block specifications with system, optical, and firmware engineers, and you will lead technical trade-offs around noise, bandwidth, timing, and electromagnetic compatibility. You will plan and execute bring-up and verification in the lab, using structured test methods and data-driven analysis to ensure compliance with requirements and reliability targets. You will also coordinate and technically guide subcontractors and suppliers, and help evolve the team’s design process, documentation, and review practices.

• Own the design and verification of analog, mixed-signal, and RF/high-speed electronic subsystems, from architecture through schematic/PCB, bring-up, and industrialisation
• Act as the analog/RF reference in R&D, driving cross-team specifications, design reviews, and supplier execution to deliver robust, production-ready hardware

What you'll Bring

We are looking for a candidate with a Bachelor’s or Master’s degree in Electronic or Opto-electronic Engineering (or equivalent) and at least seven years of relevant experience designing complex, high-performance hardware modules. You have strong expertise in analog and mixed-signal design (low-noise, precision, and high-speed) and RF fundamentals (impedance matching, transmission lines, filtering), and you apply signal-integrity and power-integrity best practices to deliver repeatable performance—including on high-performance, low-noise mixed-signal PCBs.

You are comfortable creating and reviewing schematics and PCB layouts (Altium Designer), using simulation and modelling tools (e.g., LTspice), and working hands-on with laboratory instruments (oscilloscopes, spectrum/network analyzers, signal generators) to validate performance. You communicate clearly with internal stakeholders and can present technical results and recommendations. Fluency in English is required; French is an advantage.

• Senior-level analog and RF/high-speed hardware expertise, with proven delivery of industrial-grade electronics from prototype to product
• Structured, hands-on engineer who can lead technical decisions, verification, and cross-functional execution in a fast-paced R&D environment
