Position Overview

This engineering position, in the Systems & Test Engineering group, will support all cell-related aspects of our battery management system (BMS) software. The primary objective is to develop software that ensures our products will function safely and with world-class performance.

About the Role – You will:

• Create and maintain mathematical models of lithium-ion cell behavior.
• Develop experiments to parametrize and validate models. Analyze resulting data.
• Develop on-board real-time algorithms that involve cell behavior: state-of-charge, state-of-health, power limits, temperature estimation, etc. Work with BMS engineers to implement algorithms.
• Devise cell level and pack level experiments that can test algorithm performance.
• Evaluate system performance during simulated faults and participate in lab/field fault investigations.
• Interface with vehicle teams and external OEM partners.
• Analyze algorithm performance from real world vehicle data and use learnings to propose algorithm/model improvements.
• Investigate the use of physics-based models and machine learning to build better algorithms and models.

About Our Group:

• As strategic partners, the Engineering team strives to ensure that our values, culture and engagement always allow us to do great things for our company.
• We strive to provide the highest-level service and support to our clients each and every day.
• We work collaboratively to build strong relationships with our clients, partners, and own team.
• We treat each other with respect… and always try to have a little fun every day!
• This position will be part of the Battery Engineering team that supports Proterra’s Manufacturing and Engineering operations.
• You will report to the** Director of Battery Systems and Applications **and collaborate with other Engineering team members located at our headquarters in Burlingame, CA and manufacturing facilities in Los Angeles, CA and Greenville, SC.

About You:

• Self-starter with the ability to adapt interpersonal styles and techniques to influence at all levels of the organization.
