• Utilize simulation and modeling tools to analyze circuit performance and optimize designs before hardware fabrication.
• Support product architecture decisions while balancing performance, manufacturability, reliability, and cost.

Hardware Integration & Validation

• Integrate mixed-signal hardware while minimizing noise, signal integrity issues, and EMI/EMC concerns.
• Develop and execute hardware verification, validation, and compliance test plans.
• Troubleshoot prototype and production hardware using industry-standard laboratory equipment.
• Support environmental, functional, and regulatory testing activities.

Embedded Hardware Support

• Collaborate closely with firmware, software, mechanical, and systems engineers throughout product development.
• Develop or modify firmware and automated hardware test scripts when needed.
• Support hardware bring-up, debugging, and system-level integration.

Documentation & Quality

• Create and maintain engineering documentation including schematics, design reports, test procedures, and manufacturing documentation.
• Participate in design reviews and configuration management activities.
• Ensure products comply with internal quality standards, engineering processes, and applicable industry requirements.
• Identify opportunities to improve engineering workflows, product quality, and manufacturing efficiency.

What You'll Bring

• Strong problem-solving mindset with the ability to diagnose complex electrical issues.
• Excellent collaboration and communication skills across multidisciplinary teams.
• Attention to detail with a commitment to engineering excellence.
• Ability to balance technical innovation with practical execution in a fast-paced environment.
