Ability to work in a fast-paced, regulated environment with attention to detail.

Responsibilities

Lead the design, development, prototyping, and testing of electrical hardware for implantable devices, including analog and mixed-signal circuits, low-power electronics, power management systems, and wireless communication interfaces such as Bluetooth Low Energy and radio-frequency telemetry.
Architect system-level electrical designs that address implantable constraints, including ultra-low power consumption, biocompatibility, miniaturization, hermetic packaging, and long-term reliability.
Perform circuit simulation and schematic capture; oversee printed circuit board layout; and conduct hardware verification and validation, including electromagnetic compatibility and electromagnetic interference testing under ISO 14708.
Conduct design failure mode and effects analysis, root-cause investigations, and failure-mode testing to ensure device safety and efficacy.
Collaborate with firmware, mechanical, systems, clinical, and quality engineering teams to integrate electrical subsystems and support closed-loop therapies.
Drive compliance with medical device standards and regulations, including ISO 13485, ISO 14971, ISO 14708, and the IEC 60601 series.
Mentor and provide technical guidance to junior electrical engineers, lead design reviews, and contribute to strategic technology roadmaps.
Support sustaining engineering for existing products, including troubleshooting, design improvements, and regulatory submissions.
Stay current with advancements in implantable electronics, including custom application-specific integrated circuit development, battery technologies, and neuromodulation systems.

Desired Qualifications

A master's or Ph.D. in Electrical Engineering or a related field.
Experience with neuromodulation, cardiac rhythm management, or closed-loop implantable systems.

About the Company

Enterra Medical

Develops implantable gastric electrical stimulation therapy

Enterra Medical develops and sells the Enterra Therapy system, a gastric electrical stimulation device used to treat drug-refractory gastroparesis. The system uses a small implantable neurostimulator in the lower abdomen and two leads placed in the stomach wall to deliver mild electrical pulses that help reduce nausea and vomiting, with stimulation adjusted by a physician and reversible if needed. Enterra Medical operates independently with Medtronic as an operational partner, continuing development like the Enterra II MR Conditional system and the newer Enterra ReliaStim lead to improve placement and MRI compatibility. The goal is to improve quality of life for patients with gastroparesis by providing a safe, adjustable, and reversible therapy when diet and medications have failed, and to expand applicable indications through ongoing research.
