Energy Storage System Architect
Comfortable working with high-voltage power electronics? Prefer kW versus mW? Then please read on. FreeWire Technologies is looking for an Energy Storage System Architect to design the next generation of battery packs for our mobile energy storage systems. This involves interfacing between lithium-ion battery modules, power electronics (battery management system, inverter, charger, etc), and safety controls. You will be tasked with all phases of development; from initial design to sourcing components to full production and integration with the rest of the system. Extensive experience with lithium-ion batteries is vital, and a background in the automotive industry is highly valued. This is a hands-on role that will include lots of prototying and testing. We are in the process of ramping up production, so scalability and cost minimization will be key considerations in any proposed designs.
One example project is designing a standardized method to parellel our Mobi systems - both AC and DC models - for higher power AND higher capacity. Others would be evaluating and sourcing batteries, improving BMS profiles, and designing wiring harnesses. You will report to and work closely with the Director of Engineering to ensure all designs are consistent with overall system architecture and cost targets, but you will also have a lot of autonomy to work on these projects. We're always open to new and creative ideas to reduce time to market and improve manufacturability.
The right candidate will bring an entrepreneurial spirit and be ready to take charge from day one. We need someone driven, responsible, communicative, and with great attention to detail. FreeWire is growing quickly and your compensation and responsibilities will grow with it.
- At least five years of hands-on work experience with lithium-ion battery systems
- Undergraduate degree in electrical engineering or equivalent preferred, but not required
- Past projects showcasing battery system integration with high-voltage power electronics
- Ability to work collaboratively with a team
- Interest in electric vehicles and grid integration are big plusses
$75K – $95K plus equity
Junior Electrical Engineer - Power Electronics
Comfortable working with high power electronics? Prefer kW versus mW? Then please read on. FreeWire Technologies is looking for an power electronics engineering intern to help design and build innovative new energy storage systems. This involves interfacing between lithium-ion battery modules, power electronics (battery management system, inverter, charger, etc), as well as safety controls, operational design, and a firmware/software layer that link our energy storage units to user interfaces.
The right candidate will bring an entrepreneurial spirit and take charge of the entire product life cycle - everything from hardware design to building, testing, and developing control systems. This person should be interested in electric vehicles, battery technology, and grid integration. Some experience with firmware/hardware integration is a huge plus.
We need someone driven, responsible, and communicative. FreeWire is growing quickly. Our work environment is open so the opportunity to expand your knowledge and skill-set is limitless.
- Undergraduate degree in EE or equivalent, plus hands-on experience.
- AutoCAD, Solidworks, LabView, Simulink, Matlab, and other relevant tools.
- Some experience in hardware architecture, development, testing, documentation, and deployment.
- Ability to design systems that meet current demands and are easily scalable.
- Creativity, passion, and the ability to work quickly in small groups.
*** Note: You will start out with simple tasks (wiring harnesses, assembly, etc), but we fully expect you to move up to more complex tasks quickly. Salary and position increases will be commensurate with your growth. ***
