Sensing & Instrumentation Engineer (Cryopreservation)

Location: Bay Area, United States; Workplace: On-site

Company

hirify.global is developing organ-scale reversible cryopreservation technology to preserve donated organs at subzero temperatures without ice formation and rewarm them uniformly for transplantation.

What you will do

• Design, build, and debug sensing hardware for organ preservation systems.
• Develop electronic instrumentation for measuring faint biological signals.
• Own mixed-signal PCB design from schematic capture through layout, fabrication, and bench bring-up.
• Use FPGAs for real-time acquisition timing, data streaming, and instrument control.
• Integrate sensors, boards, firmware, and software into reliable instruments.
• Build test fixtures, experimental setups, and control software for sensor validation on real organs.

Requirements

• Strong command of circuit theory and measurement physics, including impedance, noise, signal integrity, sampling, and electromagnetics.
• Experience taking analog and digital circuits from schematic through PCB layout and bench bring-up.
• Experience with instrumentation, data acquisition, FPGAs or embedded systems, and object-oriented programming.
• Ability to reason from first principles, make order-of-magnitude estimates, and debug ambiguous hardware problems.
• Systems thinking across interfaces, integration, and complete instrument behavior.
• BS or MS in electrical engineering, physics, or equivalent demonstrated expertise.

Nice to have

• Experience spanning optics, photonics, chemistry, or organ science.
• Demonstrated ability to explain project decisions, physical reasoning, and incorrect initial models in depth.

Culture & Benefits

• Small, fast-paced, interdisciplinary engineering team.
• Medical, dental, and vision insurance coverage.
• Flexible time off and paid holidays.
• Salary, equity, 401(k), FSA, and commuter benefits.
