Position Summary

The Embedded Systems Hardware Engineer designs, prototypes, tests, and troubleshoots embedded controller hardware used in industrial sensor products. This role works across the full lifecycle of embedded electronics, from early schematic and layout through validation, production support, and field-driven design iteration. The position combines hands-on hardware development with close collaboration across firmware, test, and manufacturing teams as products scale into volume deployment.

Responsibilities

Design and develop embedded controller hardware for industrial sensor systems, from concept through production release
Own schematic capture, component selection, and PCB layout for small form-factor boards, including power, signal integrity, and manufacturability considerations
Develop and validate designs using embedded CPUs (primarily ESP32 family), ADCs, power regulation, battery management, and peripheral interfaces
Prototype, test, and debug hardware using bench instrumentation and in-system diagnostics
Collaborate closely with firmware engineers to support multiple code branches, enabling hardware features and debugging system-level behavior
Contribute targeted diagnostic and validation firmware (e.g., logging hooks, input validation, test routines) to accelerate hardware bring-up and troubleshooting
Partner with test, manufacturing, and field teams to refine existing designs based on real-world performance, reliability, and deployment feedback
Support production ramp and sustaining engineering activities as products are delivered in volume

Education

Required Qualifications

Bachelor's degree in Electrical Engineering or closely related field

Experience

Hands-on experience designing embedded hardware using ESP32-class microcontrollers
Experience designing power systems, including battery-powered devices, charging, and power management
Experience with PCB schematic capture and layout for compact, high-density boards

Skills

Strong understanding of analog-to-digital conversion, signal conditioning, and mixed-signal design
Proficiency with board-level interconnects and serial bus technologies (e.g., SPI, I²C, UART, CAN)
Ability to debug hardware-firmware interactions using scopes, logic analyzers, and diagnostic code
Strong problem-solving skills with attention to detail
Excellent communication and collaboration skills across technical teams

Preferred Qualifications

Experience supporting hardware designs through manufacturing and field deployment
Familiarity with industrial sensor systems or ruggedized embedded products
Experience contributing to embedded firmware, particularly diagnostic logging and validation code
Exposure to custom or application-specific microcontrollers beyond ESP32 platforms
Knowledge of EMI/EMC design considerations for industrial environments
Experience with fermentation, brewing, or process control applications

Team Working Style

Works closely with firmware, test, and manufacturing teams to solve cross-disciplinary problems
Comfortable balancing new product development with iterative improvement of deployed designs
Values practical debugging, clear communication, and learning from field data

Physical Requirements And Work Environment

Ability to sit and stand for extended periods while working at a workbench and computer
Ability to lift up to 25 pounds occasionally for equipment and prototype handling
Lab/office environment with access to electronics testing equipment
Minimal travel required (occasional visits to manufacturing facilities or customer sites)
