Proterra offers a dynamic and supportive workplace where our employees can thrive personally and professionally. With cutting-edge facilities and groundbreaking projects, Proterra offers unique opportunities to grow, collaborate, and lead transformative changes in the electrification of heavy-duty transportation and equipment.

Our commitment to innovation extends beyond our battery solutions to our people, where we create an environment where everyone feels valued, supported, and empowered to drive change for the earth. Here at Proterra we strive to foster a culture of inclusivity, valuing diverse perspectives and encouraging bold ideas, allowing our employees to bring their full selves to work. Our employees benefit from competitive total rewards packages, and opportunities to develop professionally.

The Embedded System team is responsible for defining, designing, and testing battery pack power electronics controls features and functions for all Proterra products. It is also responsible for maintaining and supporting current production programs to provide design-focused support and technical issue resolution.

As a member of this engineering team, you will work in an engineering support role who is responsible for driving the cell algorithm controls design, cell limits on embedded subsystem architecture, design documentation, and working with manufacturing engineering to design cell quality metrics to ensure that we follow the entire product development cycle. This role combines deep electrochemical characterization and controls engineering expertise with strong systems thinking, cross‑functional leadership, and a drive for innovation and product excellence.

You will be the component manager for BMS application layer/cell integration and support controls designs from the concept through production, ensuring compliance with safety, regulatory, thermal, vibration, structural, and manufacturability requirements.

• Design and maintain high quality cell controls algorithms (including SOC, SOH, thermal controls, and power limits)
• Develop and maintain and validate cell models, enabling using experimental parameters and field data to further optimize performance
• Support integration of code into BMS controls to implement on a pack or system level
• Support and own cell centric requirements for feature algorithms around cell monitoring, diagnostics, performance, thermal management, and safety.
• Participate in detailed DFMEA and DVP&R documentation creation
• Responsible for the development of technical project plans and schedules covering engineering activities, meeting all design control and product development SOP requirements
• Support the transition of designs from prototype to high-volume manufacturing, focusing on Design for Manufacturing (DFM) and Design for Assembly (DFA)

• Degree in Electrical Engineering, Chemical/Electrochemistry Engineering, Mechatronics, Control Systems or related field; bachelor’s with 5+ years OR Master’s with 3+ industry experience in BMS controls modeling/design
• Strong Proficiency in MATLAB/Simulink and or Embedded C/C++
• Experience in BMS development, cell modeling, or battery cell testing
• Strong understanding of Lithium‑ion and chemistry, control theory, and BMS communication protocols (CAN, UDS)
• Experience with Vector tools (CANalyzer, CANape), revision control repositories (GIT)
• Strong background with DFMEA, PFMEA, FTTI, etc.
• Strong problem‑solving skills and the ability to perform root cause analysis

• Prior experience in high voltage battery systems, energy storage or EV industry
• Deep knowledge of battery electrical components (cells, modules, current collectors, busbars, module to pack integration etc)
• Knowledge of manufacturing test processes unique to battery pack construction (e.g., capacity testing, broken weld detection, etc.) a bonus but not required
• Knowledge of other cell chemistries (LFP, NMC)
• Knowledge…
