Emi Design Engineer Jobs in Reno, NV (NOW HIRING)

Senior Electronics Design Engineer

About the Role

As a Senior Electronics Design Engineer, you will design and develop the low-voltage and mixed-signal hardware that controls, senses, and protects our Solid-State Transformer (SST) subsystems. You'll own boards end-to-end - from schematic through bring-up and release to production and contribute to architectural decisions. This is a hands-on role for an engineer who wants depth in mixed-signal design for high-reliability power conversion products.

Responsibilities

• Design low-voltage and mixed-signal circuits for SST products, balancing performance, reliability, safety, cost, and manufacturability.
• Select microcontrollers and key ICs; engage with silicon vendors to evaluate fit and review errata.
• Design and validate control, sensing, and protection circuitry - including analog measurement chains, digital I/O, and fault detection.
• Design isolated interface circuits like signal isolators, isolated DC-DC, and fiber optics between different voltage domains.
• Build redundancy and fault tolerance into board designs to meet single-fault-tolerant and product-lifetime requirements; contribute to DFMEA and derating reviews.
• Implement industrial and high-bandwidth communication interfaces (e.g., Gigabit Ethernet, CAN, Modbus) with attention to signal integrity.
• Partner with a dedicated PCB layout engineer. Define stackup, impedance, isolation, and routing constraints, review iterations, and execute layout directly when needed.
• Own full lifecycle development of PCBAs: specifications, schematics, BOM, prototyping, bring-up, EMI/EMC compliance, and release to production.
• Collaborate with firmware engineers on interface and timing definition, and with mechanical engineers on connector placement, thermal, and enclosure integration.
• Maintain documentation of requirements, design decisions, and release notes for traceability and compliance.

Qualifications

• BS or MS in Electrical Engineering, Computer Engineering, or equivalent industry experience.
• 5+ years designing low-voltage and mixed-signal hardware, with at least some experience in high-reliability or high-voltage systems.
• Experience taking boards from schematic through bring-up and production, including MCU selection and protection circuitry.
• Solid analog and mixed-signal design skills, with knowledge of component selection and derating for harsh environments.
• Experience designing isolated interface circuits between voltage domains.
• Hands-on experience with communication interfaces such as Ethernet, CAN/CAN-FD, or Modbus.
• Proficiency with PCB CAD and simulation tools (preferably Altium Designer, SPICE, and/or PLECS).
• Hands-on PCB layout experience sufficient to specify constraints, review layout, and execute layout directly when needed.
• Strong board bring-up, debugging, and lab testing skills, with working knowledge of EMI/EMC best practices.
• Excellent written and verbal communication in English.
• Willingness to travel up to 10%, including internationally.

Bonus Qualifications

• Shipped a PCBA in a high-volume product.
• Exposure to functional safety (IEC 61508, ISO 13849) or HV design and certification standards (IEC 61800, UL 508C, IEC 62477).
• Experience with high-reliability design for industrial, grid, or similar harsh-environment applications.
