The Opportunity

As Principal Electrical Engineer , you will serve as the technical leader for analog and mixed signal electronics across our portfolio of advanced scientific instrumentation. This role will inherit and expand upon decades of engineering expertise, becoming the primary authority for the design, performance, and reliability of the electronics that power our world-class measurement systems.

As a hands-on technical leader, you will define system and circuit architectures, solve complex instrumentation challenges, and guide the development of precision electronics operating in demanding environments that combine ultra-low level signal measurement with high-speed digital systems, power electronics, and magnetic-field control. You will also lead and mentor a growing electrical engineering team, providing technical direction, design oversight, and knowledge transfer while remaining actively involved in design, troubleshooting, and product development.

This position is ideal for an experienced engineer who enjoys balancing deep technical problem solving with team leadership and is passionate about developing innovative electronics that enable cutting edge scientific research around the world.

Responsibilities

Serve as the senior technical lead for analog and mixed-signal electronics across Quantum Design's instrument platforms

Define board level and system level architectures for precision measurement systems, working from instrument performance requirements down to individual electronic subsystems

Design precision analog and mixed-signal circuitry, including schematic capture, PCB layout, prototyping, testing, and design validation

Develop grounding, shielding, isolation, and partitioning strategies that enable reliable measurement of low-level signals in electrically noisy environments

Lead the electrical engineering team by setting priorities, reviewing designs, mentoring engineers, and helping develop technical talent within the group

Work closely with firmware, FPGA, software, mechanical, and systems engineers to ensure new designs meet overall instrument requirements

Troubleshoot complex board and system level issues, using targeted testing and analysis to identify root causes and implement effective solutions

Own EMC and electrical safety compliance for new and existing products, including diagnosing and correcting issues uncovered during testing and certification activities

Review digital, FPGA, and firmware designs to ensure they support overall system objectives and coexist successfully with sensitive analog circuitry

Modernize existing designs by addressing component obsolescence, improving manufacturability, and extending product life while preserving proven performance

Create clear technical documentation, including design decisions, analyses, test results, and implementation details that can be maintained and understood for years to come

Support manufacturing, quality, and service teams in resolving production and field issues and improving overall product reliability

Minimum Qualifications

Bachelor's degree in Electrical Engineering, Electronics Engineering, Engineering Physics, or related discipline required

Eight years of mixed-signal circuit board design experience spanning both schematic design and board layout

Two years of leading and supervising technical teams

Preferred Qualifications

Experience with Altium Designer

Firmware development in C/C++ for microcontrollers across bare-metal, RTOS, and full-OS environments, plus PC-side test code for exercising instruments and their component circuits

Experience coding and debugging HDL in an FPGA environment

High-voltage (to ~20 kV), low-current (~µA) circuit design and dielectric isolation

Additional Information

This position’s work mode is 100% onsite. The employee will report to our facility in San Diego, CA five days a week

Salary Range: $150,000 - $215,000

Benefits include medical, dental, vision, 401(k) with company match, paid time off, paid holidays, employee assistance program, and other company-sponsored benefits
