Adraxe - Company Overview

Adraxe Corporation is an innovative medical device startup focused on the design, development, and launch of breakthrough, minimally invasive neuromodulation solutions to address unmet patient needs. The results from the first clinical epilepsy patients are encouraging and we are at the important stage of hiring key personnel, to accelerate our progress and starting our full product and clinical development. Our goal is to revolutionize neurological care with life-compatible, closed-loop neuromodulation therapies, starting with epilepsy.

About the role
We are seeking a highly experienced and technically driven Principal Electrical Engineer to drive the electrical design and development of next-generation closed-loop active implantable medical devices for neuromodulation applications. This individual will be a key contributor to the architecture, design, verification, and commercialization of Class III implantable systems that integrate sensing, stimulation, telemetry, and power management functions.

The ideal candidate has a deep understanding of implantable electronics, analog/mixed-signal circuit design, implanted system constraints, and medical device regulatory requirements (ISO 13485, IEC 60601, ISO 14708). You will collaborate cross-functionally with firmware, mechanical, systems, and clinical teams to translate therapy concepts into safe, reliable, and manufacturable devices.

This position will report directly to the VP and Chief Engineer and will have significant input into Adraxe strategy, planning, and operations.

• Drive prototype development, bench testing, and design characterization for implantable hardware.

• Provide technical leadership to multidisciplinary design teams and mentor junior engineers.
• Champion design best practices, design for reliability (DfR), and design for manufacturability (DfM).
• Driving verification and validation (V&V) activities, including unit, integration, and system-level testing to ensure reliability and traceability

• Lead design verification testing (DVT) and verification planning to ensure compliance with medical device standards and safety requirements.
• Ensure designs meet relevant standards (e.g., IEC 60601, ISO 14708, ISO 14971, EMI/EMC compliance).

• Interface with systems engineering, software, mechanical design, and clinical science teams to define and optimize system performance.
• Collaborate with regulatory and quality teams to ensure successful design history file (DHF) documentation and submission readiness.
• Engage with manufacturing partners to define testing, suppliers, and process definition.

• B.S. in Electrical Engineering, Biomedical Engineering, or related field.

• 10+ years of experience in electrical design for active implantable medical devices (AIMDs), such as neurostimulators, pacemakers, or cochlear implants.
• Proven track record designing low-noise analog front ends, stimulation circuits, power management, and wireless telemetry (RF and inductive coupling).
• Deep knowledge of implant power and safety considerations.
• Familiarity with closed-loop control systems and physiological signal acquisition.
• Experience operating within a quality system supporting Class III systems.

• Proficient in analog/digital mixed-signal design tools (e.g., SPICE, Altium, Cadence).
• Strong understanding of embedded systems interfaces (SPI, I²C, UART).
