Job Title: Senior Embedded / Analog Power Electronics Engineer

Location: Onsite in Westford MA

Duration: Long Term

Responsibilities

Job Summary

• We are seeking a Senior Embedded / Analog Power Electronics Engineer to support the development of low-voltage amplifier products currently in early prototype stages. This is a Sr Level Individual Contributor and we’ re looking for someone who can contribute immediately with minimal ramp-up.
• The end product is an Audio Amplification system for alarm systems, though no Audio experience is not required. The ideal candidate has strong analog fundamentals, power conversion experience, and is comfortable troubleshooting hardware hands-on in the lab.

Project Overview

• Two amplifier designs in development: 50W single-channel and 100W multi-channel
• Input voltage: 24V
• Switchable output range: 25–70V
• Designs are complete and in first-round prototypes
• Several months of remaining development work
• Focus on distortion, efficiency, and reliability

Responsibilities

• Review and refine designs at the schematic level (amplifier circuits, relays, isolation barriers)
• Troubleshoot and debug prototype hardware in the lab
• Support validation and testing using standard electronic test equipment
• Analyze and reduce distortion and performance issues
• Design, review, and troubleshoot DC-DC converters
• Evaluate and apply power converter topologies
• Collaborate with other engineers to resolve hardware issues
• Document test results, findings, and design updates
• Take on additional embedded hardware work as needed

Required Qualifications

• Senior-level experience in analog electronics and embedded hardware design
• Strong background in power electronics
• Hands-on experience with DC-DC converters
• Solid understanding of power converter topology
• Experience working with high voltage, low power systems
• Ability to perform schematic-level reviews
• Hands-on lab experience supporting hardware tests and debugging
• Experience using oscilloscopes, power supplies, electronic loads, and similar test equipment
• Well organized and able to work independently with minimal oversight
• Strong communication and collaboration skills

Preferred Qualifications

• Experience with more complex or isolated power converter designs
• Exposure to audio-adjacent systems or distortion analysis
• Ability to manage multiple embedded hardware tasks
