•

Design, build, and debug sensing hardware.

•

Develop electronic instrumentation that reads faint biological signals.

•

Own mixed-signal PCB design from schematic capture through layout, fab, and bring-up.

•

Work with FPGAs to orchestrate the instrument in real time: acquisition timing, data streaming, and control.

•

Integrate sensors, boards, firmware, and software into one instrument that runs reliably inside the organ preservation system.

•

Reason from first principles, using circuit theory, optics, and measurement physics to model system behavior and debug ambiguous hardware problems.

•

Build test fixtures, experimental setups, and control software for validating sensors on real organs.

•

Learn quickly, own problems end to end, and contribute across the sensing stack, from transducer to data.
•

You have a strong command of circuit theory and measurement physics (impedance, noise, signal integrity, sampling, electromagnetics), and reach for them instinctively when hardware misbehaves.

•

You can walk us through a project in depth: what you built, the physics reasoning that got you there, and where your first mental model was wrong.

•

You make order-of-magnitude estimates quickly and can explain the intuition behind them.

•

You’ve taken real analog and digital circuits from schematic through PCB layout and bench bring-up.

•

You have experience with instrumentation, data acquisition, FPGAs or embedded systems, and object-oriented programming.

•

You think in systems: interfaces, integration, and how a board behaves inside the whole instrument, not just on the bench.

•

You're excited to work at the edges of your field: the instrument spans optics, photonics, chemistry, and organ science, and you'll learn what you don't know.

•

You have a BS/MS in EE, Physics, or equivalent self-taught depth; we care more about demonstrated reasoning ability than credentials.

•

You want to join a small, fast-paced team on an excellent adventure.
