e2Companies is seeking a Senior Systems Engineer to join the Research and Development team to support the advancement of next generation energy storage, high voltage power infrastructure, and integrated generation technologies. This role will work closely with senior technical leadership to support system architecture development, battery and protection strategy design, high voltage testing methodologies, and proprietary control and modeling platforms. The Senior Systems Engineer will contribute to both theoretical research and practical implementation, ensuring scalable system design, validation rigor, and long-term technical continuity. The ideal candidate brings strong academic grounding in power systems or electrochemical systems, combined with hands-on laboratory, modeling, and software development experience, and demonstrates readiness to assume increasing technical ownership within a growth-stage innovation environment.
This position requires full-time, on-site employment at our Bonita Springs, Florida headquarters. Relocation assistance is available for qualified candidates willing relocate to Southwest Florida.
RESPONSIBILITIES
Research and System Architecture
- Lead and support research and development activities related to battery systems, high voltage insulation systems, and grid-interactive power architectures.
- Evaluate system components and recommend architectures, formulations, and design modifications to meet product performance, safety, and lifecycle requirements.
- Evaluate high energy active materials and cell architectures, integrating material selection and formulation into system-level performance objectives.
- Conduct ongoing technical literature research to inform material selection, degradation modeling, and system design strategies.
- Engage with suppliers and technology partners to evaluate emerging materials, components, and system integration strategies.
Battery and Laboratory Development
- Specify and test prototype cells or subsystems, quantitatively analyzing performance to support design decisions.
- Define, validate, and standardize laboratory test procedures, equipment configurations, and experimental protocols.
- Design and execute laboratory validation programs including insulation testing and analysis, electromagnetic compatibility evaluation, and cycle life testing.
- Apply diagnostics, failure mode, and contingency analysis to identify root causes of performance limitations and generate technically sound corrective solutions.
- Champion environmental health and safety standards within laboratory and validation environments.
Modeling, Software, amp; Controls
- Perform modeling and simulation of power systems, transient events, protection coordination, and degradation mechanisms using MATLAB or equivalent analytical tools.
- Develop and maintain engineering software tools and internal platforms in C# to support system modeling, data analysis, automation, and algorithm implementation.
- Contribute to control logic development and system-level algorithm design for energy storage and distributed generation platforms.
- Collaboration, Leadership amp; Governance
- Collaborate with cross-functional engineering and manufacturing teams to translate research findings into deployable, production-ready systems.
- Mentor laboratory technicians and junior engineers to ensure high quality execution and technical understanding of experimental work.
- Support technical documentation, validation reporting, intellectual property development, and structured knowledge transfer processes.
- Present research findings and technical recommendations to executive leadership and internal stakeholders.
- Other duties as assigned.
