Embedded / Controls Engineer (On-Site - Quincy, IL) in Quincy

Job DescriptionJob Description

Embedded / Controls Engineer (On-Site – Quincy, IL)

We design and build custom industrial control systems used in fuel handling, additive injection, card lock access, and biodiesel blending. Every system is developed, built, and tested in-house.

This is a hands-on role working directly with hardware—not a remote software job.

What You’ll Do

• Develop firmware for custom PCBs (primarily AVR / ATmega in C)
• Interface with real-world hardware: pumps, valves, flow meters, sensors
• Bring up and debug boards using oscilloscope, logic analyzer, etc.
• Work directly with two engineers to design and refine systems
• Build one-off and small-batch solutions tailored to customer needs
• Troubleshoot issues in the lab and occasionally in the field

What We’re Looking For

• Strong C programming for microcontrollers (bare metal or lightweight RTOS)
• Experience with embedded systems (AVR, STM32, or similar)
• Comfortable working close to hardware (GPIO, ADC, SPI, I2C, UART)
• Able to debug real-world issues (noise, timing, edge cases)
• Practical mindset—someone who builds and fixes things, not just writes code

Nice to Have

• PCB design or schematic experience
• Industrial controls or automation background
• Experience with fuel systems, pumps, or fluid handling
• Bootloaders, communications protocols, or data logging

Work Environment

• 100% on-site in Quincy, IL
• Small, collaborative team (you’ll work directly with the people designing the systems)
• Full access to lab equipment and hardware
• Minimal meetings, maximum building

Why This Role

• You’ll work on real systems, not abstractions
• You’ll see projects from concept → build → deployment
• No corporate layers—your decisions directly impact the product

Important
This is an on-site role. We are not considering remote applicants.

If you enjoy working with real hardware and solving practical engineering problems, we’d like to talk.
