Until is building sensing and instrumentation technology for organ preservation systems. This role focuses on designing, building, and debugging hardware that reads faint biological signals in a real-time measurement context.
You will own mixed-signal PCB design end-to-end: from schematic capture through layout, fabrication, and bench bring-up. You'll work with FPGAs to orchestrate real-time acquisition timing, data streaming, and instrument control. A core responsibility is integrating sensors, boards, firmware, and software into a cohesive instrument that operates reliably within the organ preservation system.
The work spans the full sensing stack—from transducer physics through data acquisition to system integration. You'll reason from first principles using circuit theory, optics, and measurement physics to model system behavior and debug hardware problems. You'll also build test fixtures, experimental setups, and control software for validating sensors on real organs.
This is a systems-level role: you'll think about interfaces, integration, and how boards behave inside the whole instrument, not just on the bench. The instrument spans optics, photonics, chemistry, and organ science, so you'll be learning at the edges of your field and contributing across disciplines.
REQUIREMENTS:
- Strong command of circuit theory and measurement physics (impedance, noise, signal integrity, sampling, electromagnetics)
- Demonstrated experience taking real 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
- BS/MS in EE, Physics, or equivalent self-taught depth (demonstrated reasoning ability valued over credentials)
- Ability to make order-of-magnitude estimates and explain the intuition behind them
- Systems thinking: understanding interfaces, integration, and whole-instrument behavior
- Comfort working at the edges of your field and learning unfamiliar domains (optics, photonics, chemistry, organ science)
