Hardware Engineer

The role

This person will build the sensing side of growth rigs and program microcontrollers. They will perform breadboard and prototype-level fabrication and manage the power side.

What you will do

• Build the sensing side of growth rigs including thermocouples, optical sensors, cameras, and pressure sensors
• Program microcontrollers for sensor sampling, control loops, motor sequencing, and host comms
• Perform breadboard and prototype-level fabrication including protoboards, harnesses, and simple carrier boards
• Create 3D-printed brackets and basic mechanical scaffolding
• Manage the power side including heater control, motor drives, PID loops, MOSFETs, isolation, and grounding
• Take rigs from bench to reliable 72-hour growth runs
• Debug across the stack

Required qualifications

• Strong sensor integration experience
• Solid microcontroller programming
• Real breadboard and prototype-fab skills
• Light mechanical fab: basic CAD, 3D printing

Nice to have

• Materials science background
• ML background
