Contract Details

• Job Title: Hardware Engineer - Piezoelectric / Ultrasonic Systems
• Duration: 6 months initially
• Location: Hybrid (3 days/week) or on-site, North London
• Outside IR35

Key Responsibilities

• Design high-voltage and low-voltage analogue driver circuits for piezoelectric transducers, including pulser and continuous-wave excitation stages.
• Develop low-noise analogue receive chains for ultrasonic signal acquisition, including LNAs, VGAs, filtering, and signal conditioning.
• Design and optimise impedance matching networks to improve power transfer, sensitivity, and system efficiency.
• Design and iterate PCB layouts for ultrasonic drive, receive, and mixed-signal subsystems.
• Integrate piezoelectric transducers into complete hardware systems including power electronics, ADC/DAC stages, timing circuits, and embedded or FPGA-based control.
• Support prototype development, bring-up, debugging, and rapid hardware iteration.
• Develop and execute test and validation procedures for ultrasonic hardware performance.
• Collaborate with acoustics, mechanical, and systems engineers to ensure correct transducer operation and integration within the full system.

Essential Skills

• Strong analogue electronics design experience
• Experience with precision analogue circuit design
• PCB design/layout experience using tools such as Altium, KiCad, or equivalent
• Hands-on laboratory experience with oscilloscopes, signal generators, and measurement equipment
• Understanding of signal conditioning, filtering, and low-noise design principles
• Strong hardware debugging and troubleshooting skills
• Ability to interpret experimental data and iterate hardware designs effectively
• Familiarity with embedded systems or mixed-signal hardware integration
