Job summary

Profound Medical seeks a Senior RF Electrical Developer to lead MRI-compatible device design inside the MRI bore. You will shape RF-safe architectures, mitigate interference, and ensure safety compliance while enabling high-performance operation.

The role emphasizes system-level integration, hands-on RF testing, and collaboration with clinical and regulatory teams to achieve MR Safety classifications and artifact minimization.

Qualifications

• 7+ years of RF/system design experience, preferably in MRI-compatible or electromagnetically harsh environments.
• Strong understanding of RF coupling, shielding, grounding, and filtering techniques.
• Experience designing systems exposed to high electromagnetic fields and transient interference.
• Hands-on experience with RF test equipment (VNA, spectrum analyzer, oscilloscope).
• Experience with system-level integration and debugging, not just component design.
• Solid understanding of signal integrity and noise mitigation in sensitive measurement systems.

Responsibilities

• Lead the design of MRI-compatible electronic and RF subsystems, including signal paths, filtering, shielding, and grounding strategies.
• Develop systems that are immune to MRI RF pulses and gradient-induced interference.
• Design and validate signal generation systems for high powered ultrasound that operate reliably within the MRI environment.
• Ensure RF safety compliance, including mitigation of induced currents, cable heating, and unintended coupling.
• Design filtered and shielded interconnects, including cable traps, baluns, and feedthroughs to prevent RF coupling.
• Perform EMC/EMI analysis and mitigation in the MRI environment (64–300+ MHz depending on field strength).
• Collaborate with system and mechanical teams to ensure MR-conditional design, including material selection, cable routing, and enclosure design.
• Develop and execute test methods for MRI compatibility, including phantom testing, in-bore validation, and artifact evaluation.
• Analyze and minimize image artifacts caused by device operation.
• Work closely with clinical and regulatory teams to support MR safety classification (MR Safe / MR Conditional) per standards such as ASTM F2503.
• Troubleshoot complex system interactions between the device and MRI system.
• Contribute to system architecture decisions balancing performance, safety, and usability.
