Company mission

To enable homes to get clean energy faster, cheaper and more easily. Impacting climate change is our passion.

Role

Who you are

  • MS in Electrical Engineering with a focus on Power Electronics
  • 7+ years of experience developing power electronics technologies in the automotive, energy, or aerospace industries
  • Experience with power semiconductor selection (Si/SiC/GaN MOSFETs, diodes), gate drive, and protection circuit design
  • Hands-on leadership approach whether it be building a prototype or performing testing
  • Experience leading projects and architecture with a diverse team under tight timelines
  • Solid understanding of the theory and application of magnetics (inductors, transformers) and capacitors (Electrolytic, film, and Ceramic)
  • Familiar with schematic capture and power converter circuit modeling/simulation tools
  • Experience in supervision of PCB layout for minimal stray inductance and capacitance, placement strategies for better manufacturability, power/signal plane definition, and EMC optimization
  • Knowledge of basic power electronics control theory
  • Experience with embedded programming including working with / guiding firmware developers
  • Experience working closely with contract manufacturers and leading design for manufacturing
  • Proficiency with basic EE tools (Oscilloscopes, Network Analyzers, Signal Generators, etc.)

Desirable

  • Ph.D. in Electrical Engineering with a focus on Power Electronics
  • Knowledge in environmental, reliability, and safety requirements for residential and commercial power applications
  • Experience specifying embedded controllers for power electronics – i.e. choosing between FPGA, microcontroller, hardware-accelerated gate drive, etc
  • Knowledge of national and international safety and EMC requirements relevant to the design of power converters such as UL, FCC, National Electric Code (NEC), IEC, and ISO
  • Demonstrated success working in a cross-disciplinary, multi-cultural environment

What the job involves

  • In this role, candidates will drive efforts to optimize our partner’s power systems integrated with SPAN’s panel, grow SPAN’s IP, and collaborate with software, firmware, controls, and mechanical teams to implement technologies that electrify the home and delight our customers
  • Distill detailed analysis of power system components and behaviors to critical metrics of concern for company-wide discussion
  • Support executive staff with business analysis of research and development projects and manufacturing options e.g. outsource versus internal to SPAN and which components are ripe for vertical integration
  • Develop and validate accurate power electronics, solar, and battery models to better understand system use cases with SPAN’s panel, support modeling infrastructure, and maintain a database of relevant component models and product metrics
  • Build prototype components and assemblies and support buildout of electrical, reliability, safety, and environmental laboratories. Develop and perform tests related to compliance, safety, environmental, and reliability
  • Work with contract manufacturers throughout the full product lifecycle to have parts made to specification achieve our standards for product quality and yield
  • Work closely with the mechanical, software, and controls teams to optimize the overall product, including system thermals, compute requirements, functional safety behaviors, and design for compliance and manufacturability
  • Own full product lifecycle: specification, design, prototype, certification, reliability, validation, and manufacturing
  • Build and manage a resource plan and timeline for electronics development

Otta's take

Sam Franklin headshot

Sam Franklin

CEO of Otta

Span helps homeowners looking to improve their energy resilience by replacing electric panels, many of them decades old, with a flexible smart panel that helps users monitor and control their energy usage from a single app.

Founded in just 2018, Span has made great strides in both price and technological development and has won the International Builders' Show 2022 Best Energy Efficient Product award for its Gen 2 smart Panel. Significant funding rounds have propelled product development, including a future-looking integration of its equipment with that of solar inverter, battery, and EV charger manufacturers.

This fast-developing and innovative answer to a previously stagnant home energy feature directly caters to the increasing demand for energy efficiency in the home. This is exemplified by a 2024 partnership with PulteGroup, the third-largest homebuilder in the US. With CEO Arch Rao at the helm, previously head of Products, Application & Sales Engineering at Tesla, Span seems likely to continue on its winning streak with increasingly affordable renewable energy products.
