Controls Engineer, New Products

As the first Controls Engineer on a new engineering team, you will take a hands-on role in the design, development, and integration of a new product at Redwood. This position focuses on state-of-energy and capacity estimation for a novel lithium-ion-powered energy storage system, as well as developing control algorithms to maximize system performance.

While battery algorithms are a core focus, this role will also serve as the technical lead across all control systems for the product. We are looking for someone with strong control system fundamentals who has experience developing battery algorithms from scratch or as part of a small team.

The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to tackle novel technical challenges. If you're excited about working in a dynamic, fast-paced setting within a new department at Redwood, we want to hear from you!

If necessary, the job level will be adjusted to suit the applicant’s experience and responsibilities.

Responsibilities will include:

• Develop control architectures and algorithms for an energy storage system across multiple layers of power converters.
• Design and implement SOC/SOH estimation algorithms at the cell, pack, and system levels.
• Lead thermal control strategies for the battery system.
• Conduct system identification and modeling, determining the appropriate level of model fidelity and designing experiments for data collection and parameter estimation.
• Collaborate with embedded firmware engineers to ensure algorithm implementation in resource-constrained real-time environments.

Desired Qualifications:

• B.S. or M.S. in Mechanical Engineering, Electrical Engineering, or a related field, with 5+ years of model development or systems engineering experience.
• Strong first-principles understanding of electrical and mechanical systems, power delivery, energy storage, and thermal mechanics.
• Solid foundation in classical and modern control theory (stability, controllability, observability).
• Expertise in Li-ion battery estimation, including SOC/SOH modeling, Coulomb counting, and Kalman filters (EKF).
• Hands-on experience designing and tuning PID controllers and working with frequency-domain analysis.
• Demonstrated ability to write clear and testable engineering requirements.
• Strong communication and collaboration skills.
