Sennos is rapidly emerging as the global leader in AI-driven sensing, analytics, and control for the Fluid, Fermentation, and Bio-manufacturing industries. With a revolutionary integration of hardware, software, and real-time multi-parametric data, we have quietly built the world's most advanced sensing system and largest AI-powered fermentation data warehouse. By owning the entire stack-from sensing hardware to data infrastructure-we have delivered a breakthrough solution that reveals complex biological and chemical interactions, predicts precision outcomes, and enables next-generation production control.
Sennos is a rapidly growing start-up looking for someone who can quickly adapt to a changing environment and who has the desire to grow with us!
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 Required Qualifications
Education:
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)
