Electrical PCB designer & tester (Life science instrumentation) – Summer Internship

Company Description

37degrees, Inc. specializes in innovative cell culture products for life sciences, pharmaceuticals, and fundamental research. Our portable, connected instruments are intelligently designed to support affordable and scalable experiments that advance biological knowledge. By combining cutting-edge technology with deep scientific understanding, we empower researchers to configure novel cell and tissue culture experiments seamlessly — pushing the boundaries of discovery in the life sciences.

The Role

We're hiring a Summer Electrical PCB Designer & Tester Intern to help design, develop, and validate PCBs for our next generation of life science instruments. You'll own real circuit and layout work — not busywork — and ship boards that go into production-grade research products. You'll collaborate closely with our software, mechanical, and fluidic engineers to take designs from schematic through bring-up and validation. This is a hands-on opportunity to apply graduate-level electrical engineering to instruments that scientists actually use at the bench.

What You'll Do

• Design circuit schematics and multi-layer PCB layouts (4–8 layers) for production
• Work across analog, digital, and wireless/RF domains, integrating actuators, sensors, and interfaces
• Select components and define interface strategies for new instrument subsystems
• Perform PCB bring-up, testing, and validation
• Release production files, manage vendor interactions, and maintain EBOM, wiring, and cable documentation
• Collaborate with a multi-disciplinary engineering team to refine designs against project specs and product requirements
• Troubleshoot electronic components and iterate quickly on prototypes

Qualifications

• Currently enrolled in a Master's or PhD program in Electrical Engineering (or recently graduated)
• Strong analytical and problem-solving instincts; comfortable working independently in a remote environment

Must-Have Skills

• Expert eCAD designer, specifically KiCAD
• Proven track record producing 4–8 layer PCB schematics and layouts at production grade
• Expert in analog/digital circuit design and wireless communication
• Actuator, sensor, and interface selection
• PCB testing and validation
• Production file release and vendor management
• EBOM, wiring, and cable documentation

Strongly Preferred

• Use of AI tools for rapid PCB schematic and layout design
• Experience working in multi-disciplinary teams (software, mechanical, fluidic engineers)
• Experience with IoT Battery Management Systems (BMS)
• Experience with board compliance (EMI, RoHS, etc.)

Nice to Have

• Embedded system architecture and firmware development (C / C++)
• mCAD familiarity
• Familiarity with life science instrumentation

Logistics

• Summer Internship
• 10–20 hrs/week, flexible
• Remote, US-based
