Job Summary This leader will establish and guide a core bioengineering function that integrates computational modeling, waveform and sequence development, bench characterization, preclinical evaluation, and external scientific collaboration. The role is intended to deepen the organization’s understanding of the biology and physics of pulsed field ablation while translating that knowledge into robust catheter designs, optimized energy-delivery strategies, and differentiated therapeutic performance.

Key Responsibilities 1. Lead Sequence Development and Computational Modeling for Next-Generation PFA Devices • Build and lead a high-performing team responsible for developing pulsed field ablation sequences, waveform strategies, and dosing approaches for next-generation electrophysiology ablation platforms.

• Establish advanced simulation capabilities using COMSOL Multiphysics and other modeling tools to predict electric field distribution, thermal effects, tissue response, lesion formation, and catheter-tissue interactions.

• Develop and apply multiphysics models that integrate electrical, thermal, fluidic, mechanical, and biological considerations relevant to pulsed field ablation.

• Translate computational insights into actionable design inputs for catheter architecture, electrode configuration, energy delivery, sequence optimization, and clinical workflow.

• Create a scalable modeling framework that can support rapid iteration across catheter designs, energy-delivery recipes, and intended clinical use cases and worflows.

2. Lead Bench Testing, Characterization, and Test Method Development • Build and lead a team responsible for bench testing and characterization of ablation catheters and associated energy-delivery strategies.

• Design, develop, and validate new test setups and test methods to evaluate catheter performance, lesion formation, electric field behavior, thermal profile, fluidic behavior, and ablation consistency.

• Use bench data to validate computational simulations, refine modeling assumptions, and establish a disciplined feedback loop between modeling, prototype development, and experimental characterization.

• Partner with product development teams to evaluate evolving catheter designs, identify performance tradeoffs, and guide design improvements through quantitative data and engineering judgment.

• Ensure test methods are scientifically sound, reproducible, appropriately documented, and aligned with R&D, preclinical, quality, and regulatory expectations.

3. Enable Preclinical Evaluation of Catheters in Development • Lead a group that enables preclinical testing of ablation catheters as designs evolve through multiple iterations from early concept through design freeze and development milestones.

• Define preclinical study objectives, endpoints, and evaluation strategies that generate meaningful evidence on lesion quality, durability, safety margins, tissue selectivity, and collateral tissue effects.

• Partner closely with preclinical operations, clinical science, regulatory, quality, and product development teams to ensure studies are designed to answer critical technical and translational questions.

• Integrate preclinical findings with simulation and bench-testing outputs to guide catheter design, sequence development, and risk-benefit assessment.

• Establish disciplined review processes to ensure that preclinical learnings are captured, communicated, and translated into clear development decisions.

4. Advance Internal and External Scientific Collaboration • Establish and lead a scientific engagement strategy with internal experts, academic collaborators, research institutions, key opinion leaders, and external scientific partners to advance the field of pulsed field ablation.

• Drive research efforts that deepen understanding of the biology and physics underlying irreversible electroporation, tissue selectivity, lesion durability, therapeutic windows, safety considerations, and waveform-dependent tissue response.

• Identify emerging scientific questions and technology opportunities that can inform future product strategy, intellectual property, clinical differentiation, and next-generation platform development.

• Represent the organization in technical discussions, scientific reviews, collaborative research forums, and cross-functional strategy discussions rel
