Staff Electrical Engineer — Sensing Platform & IoT Hardware

The Electric Plant Co; San Francisco (CA); On-site; USD 225,000 - 245,000; Full time

Job summary

The Electric Plant Co. in San Francisco is hiring a Staff Electrical Engineer to own the sensing and signal-acquisition platform across analog design, embedded systems, and field deployment.

You will lead hardware development from electrode interfaces to firmware, and collaborate with the science and foundation-model teams to ensure data quality and trainability. You will drive hardware architecture, validation, and deployment for low-power IoT devices powering plant health insights, working

Qualifications

• 6–12 years developing and shipping electronic products with hardware ownership.
• Strong mixed-signal and analog design experience.
• Hands-on schematic capture, PCB design and bring-up.
• Technical leadership across disciplines.
• Embedded experience with C/C++ on ESP32/ARM and RTOS basics.
• Experience validating sensors against ground truth.
• Direct, low-ego communicator.

Responsibilities

• Set the electrical architecture for our sensing platform across analog front end, embedded systems, power, and field deployments.
• Own the mixed-signal front end for plant electrophysiology — electrode interfaces, instrumentation amplifiers, filtering, ADC chains, and noise-floor characterization against real plant signals.
• Design, review, and bring up schematics and PCBAs across the IoT hardware stack — multi-PCBA designs spanning analog front end, MCU/main, and power.
• Establish the validation methods and characterization protocols that determine whether a signal is trustworthy enough to become part of the dataset.
• Partner closely with the science and foundation-model teams to improve signal quality, evaluate new sensing approaches, and ensure the data captured in the field is actually trainable.
• Build custom lab and research hardware — purpose-built sensors, test rigs, and instrumentation that help the science team probe new signals before they become product features.
• Contribute to embedded firmware development in C/C++ across ESP32 and future low-power LoRa platforms, particularly for hardware bring-up, characterization, deployment, and debugging.
• Drive technical decisions that influence hardware performance, dataset quality, reliability, and future sensing capabilities.
• Bring up every new build with your own hands — oscilloscope, logic analyzer, and spectrum analyzer fluent.
