Electrical Engineer

Entegee; Minneapolis (MN); On-site; USD 85,000 - 120,000; Full time

Job summary

Entegee in Minnesota is seeking a seasoned PCB designer to lead full lifecycle design of mixed-signal, MCU-based boards for automotive-related applications. You will own schematics, layout, and production release, collaborating with hardware, firmware, and manufacturing teams.

You will design analog front-ends for sensors, power and protection circuits for 12/24/48V systems, and integrate CAN/J1939, LIN, RS-485/Modbus, Ethernet, and telematics interfaces to ensure robust, compliant hardware.

Qualifications

• Strong experience in mixed-signal PCB design for MCU-based systems.
• Proficiency with Altium Designer.
• Experience with automotive-grade protections and power electronics.
• Experience with EMC/EMI and ISO CISPR 25/ISO 10605 considerations.

Responsibilities

• Lead full lifecycle design of mixed-signal, MCU-based PCBs from schematic to release.
• Design analog front-end for sensors (RTD, NTC, pressure) with precision conditioning.
• Develop power distribution and actuator drive circuits for automotive components.
• Implement protection for 12V/24V/48V systems (load dump, reverse polarity, over/undervoltage).
• Integrate CAN/J1939, LIN, RS-485/Modbus, Ethernet and telematics interfaces.

Job description

• Lead full lifecycle design of mixed-signal, microcontroller-based PCBs, from schematic capture and layout through production release.
• Design analog front-end circuits for RTD, NTC, pressure, and current sensors, including precision signal conditioning and data acquisition.
• Develop power distribution and actuator drive circuits for EEVs, solenoids, contactors, fans, and pumps.
• Implement protection for 12V, 24V, and 48V automotive systems, including load dump, reverse polarity, overvoltage, undervoltage, and transient protection.
• Integrate CAN/J1939, LIN, RS-485/Modbus, Ethernet, and telematics interfaces.

PCB Design & Manufacturing

• Use Altium Designer for schematic capture, component libraries, PCB layout, and design reviews.
• Apply signal integrity, thermal management, high-current routing, and creepage/clearance design practices.
• Work with PCB suppliers and contract manufacturers to resolve DFM/DFA issues, support assembly, and transition designs into production.

Testing, Validation & Compliance

• Perform hands-on PCB bring-up, debugging, functional testing, and root-cause analysis using oscilloscopes, logic analyzers, and electronic loads.
• Design for EMC compliance and troubleshoot emissions and immunity issues related to CISPR 25, ISO 11452, and ISO 10605.
• Develop design verification plans (DVP&R), test fixtures, interface harnesses, and automated test equipment requirements.
• Support prototype, pre-production, and manufacturing validation.
