Electrical Design Engineer

Summary

Our client is an established Southern California manufacturer specializing in advanced underwater communication systems, commercial diving equipment, and specialized electronic products used by military, government, public safety, and commercial organizations.

We are seeking an experienced, hands-on Electrical Design Engineer to lead the design, development, testing, and enhancement of sophisticated electronic products, with a strong emphasis on analog and digital audio circuitry, audio amplifiers, digital signal processing (DSP), and embedded systems.

The ideal candidate brings 8–10 years of electronic circuit design experience, including hardware development, embedded firmware programming, and component-level troubleshooting. This engineer will work on specialized communication and intercom systems, supporting the complete product development lifecycle from initial concept and circuit design through prototyping, production, and ongoing product improvement.

This is an excellent opportunity for an engineer who enjoys hands-on product development, solving challenging electronic design problems, and taking ownership of highly specialized electronic systems.

Duties & Responsibilities

Electronic Circuit Design & Product Development

• Design, develop, test, and improve analog and digital electronic circuits for communication equipment, intercom systems, audio amplifiers, and other specialized electronic products.
• Develop electronic hardware and embedded firmware for new product designs and enhancements to existing products.
• Design and optimize audio signal paths, amplification circuitry, and digital audio processing systems.
• Perform circuit-level design, schematic development, component selection, simulation, prototyping, and testing.
• Design and evaluate electronic systems utilizing microcontrollers, microprocessors, DSPs, and FPGA technologies.
• Address circuit impedance matching, signal integrity, board-level electromagnetic interference (EMI), digital interfaces, and digital power requirements.
• Evaluate amplifier performance, including noise characteristics, noise figure (NF), and 1 dB compression point (P1dB), where applicable.
• Incorporate built-in self-test (BIST) capabilities and diagnostic functionality into electronic designs.
• Support development of additional electronic products, including LED lighting systems.

Embedded Systems, Firmware & Digital Signal Processing

• Develop, implement, and troubleshoot embedded software and firmware for electronic communication systems.
• Perform real-time embedded programming and hardware/software integration.
• Design and implement digital audio signal processing functions using DSPs, microcontrollers, microprocessors, and/or FPGAs.
• Troubleshoot complex hardware, firmware, and system-level performance issues.
• Perform analog and digital circuit simulation to validate and optimize electronic designs.
• Develop and execute component-level, circuit-board-level, and complete system-level testing.

Testing, Validation & Manufacturing Support

• Develop electronic prototypes, test procedures, and specialized testing fixtures.
• Perform design verification, product validation, failure analysis, and troubleshooting.
• Diagnose component-level and system-level electronic failures and implement corrective actions.
• Provide technical support to manufacturing teams, including troubleshooting production assemblies and improving testing processes.
• Support printed circuit board (PCB) and printed circuit assembly (PCA) development, fabrication, assembly, and production.
• Collaborate with manufacturing, purchasing, and quality teams on component selection, supplier qualification, and manufacturing improvements.
• Support product reliability, manufacturability, and cost optimization.
