About the Role
We are seeking an entry-level Embedded Firmware and Controls Engineer or Intern to join a small, fast-moving team designing and building large-scale industrial manufacturing equipment. This role involves working across the low-level firmware and motion control layer, from embedded code and control loops through hardware integration in a mixed PLC and custom electronics environment, with hands-on ownership from day one.
Responsibilities
- Support the development and maintenance of embedded firmware using modern languages and toolchains for custom electronics integrated into industrial manufacturing equipment.
- Implement and tune motion control systems, including servo tuning, trajectory planning, and closed-loop control, alongside senior engineers.
- Write PLC control logic in Structured Text and integrate it with machine electrical and mechanical systems.
- Work within or alongside real-time operating environments, ensuring deterministic, reliable control at the machine level.
- Troubleshoot control and firmware issues across hardware, software, and system boundaries, from logic analysis to live machine debug on the shop floor.
- Generate and maintain firmware documentation, version control practices, and controls architecture documentation.
- Work directly alongside build technicians, electrical engineers, and mechanical engineers, including remote teammates, to bring up and commission complete machine systems.
- Contribute to controls engineering standards and documentation practices as the function scales.
Requirements
- Pursuing or recently completed a Bachelor’s or Master’s degree in electrical engineering, computer engineering, mechatronics, or computer science from an ABET-accredited program.
- Relevant coursework or projects related to embedded systems, microcontrollers, real-time systems, or control theory.
- Programming experience in a language suited to embedded development (Rust, C++, C, or similar).
- Hands-on experience running code on real hardware, such as microcontroller dev boards, sensors, actuators, or motors.
- Hands-on debug ability at the bench, comfortable with a multimeter, oscilloscope, and logic analyzer.
- Working knowledge of Git and version control practices.
- Effective communicator and collaborator in a distributed team environment, comfortable with async communication and remote-first workflows.
- Flexible with schedule and hours; thrives in a startup environment where priorities shift and urgency is real.
- Willingness to travel as needed for vendor visits, factory acceptance testing, and on-site equipment commissioning.
- Comfort with a startup pace, demanding flexibility, self-direction, and a bias toward getting things done.
