Senior Electronics Engineer

Darwin Recruitment; Barcelona; Presencial; EUR 70.000 - 110.000; Jornada completa

Descripción de la vacante

Darwin Recruitment in Barcelona is seeking a Senior Electronics Engineer to join a leading European client building full-stack superconducting quantum computers, from QPUs to cryogenic infrastructure and control electronics.

You will design the signal chain, simulate SI before board fabrication, ensure grounding/shielding, and become the technical authority for the electronics layer.

Formación

• 8+ years of hands-on analog/mixed-signal and/or high-speed electronics design.
• Low-noise and signal-integrity design from first principles.
• Grounding and shielding architecture.
• Filter design from specification.
• PCB design-review depth.
• Superconducting quantum, cryogenic or low-temperature measurement experience.
• Low-noise DC biasing, twisted-pair / coaxial signal delivery, cryogenic cabling.

Responsabilidades

• Signal chain architecture – define and document how signals are generated, conditioned, filtered, routed and shielded from the electronics rack to the QPU, both DC/flux-bias and RF/readout paths.
• Grounding and shielding by design.
• Filtering and low-noise design.
• PCB design review.
• Instrument integration & validation.

Senior Electronics Engineer (Signal Integrity & Instrumentation)

One of our leading European clients is looking for a Senior Electronics Engineer to join their team in sunny Barcelona.

This business is building full-stack superconducting quantum computers, from QPUs and cryogenic infrastructure to control electronics, racks, cabling, instrumentation and deployment software.

The team is currently missing a seasoned electronics engineer who designs the signal chain right before it reaches the bench; someone who simulates signal integrity before a board is fabricated. This person woule design grounding instead of guessing it, anticipating the scaling problem, and raising the technical floor of the whole team.

Ultimately, you will become the technical authority for the electronics layer.

Responsibilities:

• Signal chain architecture – Define and document how signals are generated, conditioned, filtered, routed and shielded from the electronics rack to the QPU, both the DC / flux-bias path (DC to a few hundred MHz) and the RF / readout path (a few GHz)
• Grounding and shielding by design
• Filtering and low-noise design
• PCB design review
• Instrument integration & validation

Experience:

• 8+ years of hands-on analog / mixed-signal and/or high-speed electronics design
• Low-noise and signal-integrity design from first principles
• Grounding and shielding architecture
• Filter design from specification
• PCB design-review depth
• Superconducting quantum, cryogenic or low-temperature measurement experience
• Low-noise DC biasing, microwave engineering, attenuators, filtering, twisted-pair / coaxial signal delivery, cryogenic cabling
