Job description

We're seeking a self-directed electrical engineer who can lead the full design cycle, from schematic to implementation, across complex mixed-signal systems. This role blends deep technical design with hands-on lab work, supporting both new product development and legacy systems in a collaborative, cross-disciplinary environment.

What You’ll Do

• Design, simulate, and test analog and digital circuits using microcontrollers, FPGAs, DSPs, op-amps, A/D converters, filters, and power supplies (linear and DC-DC switching)
• Develop interface electronics for motion control, sensors, optical systems, and communications
• Capture schematics and drive multilayer PCB layout using Altium (or similar)
• Execute board bring-up, debugging, prototyping, verification testing, and performance characterization
• Provide design support for existing systems and legacy PCBs
• Communicate hardware changes with service and manufacturing teams
• Participate in evaluating emerging technologies to inform future product directions
• Collaborate closely with mechanical and software engineers on tightly integrated electro-mechanical and electro-optical systems

What We’re Looking For

• B.S.E.E. or higher with 5+ years in analog/digital circuit design
• Strong hands-on experience with lab instrumentation and debugging techniques
• Proficiency with Altium Designer and SPICE simulation tools
• Familiarity with standard digital interfaces: I2C, SPI, UART, USB, Ethernet
• Ability to manage and document work independently while contributing within a structured, team-based environment
