Control Engineer

Control Engineer - Energy Systems

Sunnyvale, United States

42dot | Full-time

We are looking for the best

We are vertically integrating all aspects of energy and thermal controls at 42dot, enabling innovation in next generation electric vehicles. As a Staff Controls Engineer, you will design and implement control features that dynamically manage and distribute power and energy across all vehicle systems to maximize battery utilization throughout lifetime and minimize energy waste, and optimize thermal energy flows across cabin, battery, and powertrain, that will empower users to drive farther, charge faster, stay comfortable, and trust their vehicle in all environments

Responsibilities

• Design and develop battery and energy control features to dynamically manage and distribute power across all vehicle systems to

  • maximize battery utilization while avoiding power violations and preserve range without compromising safety or comfort

  • ensure battery thermal conditions are always within optimal operating ranges at all time for safety, performance, charging speed, and durability

  • maintain thermal stability of drive units and power electronics to support performance, efficiency, and durability

  • optimize thermal energy flows across cabin, battery, and powertrain to minimize redundant energy use and maximize overall system efficiency

  • allow maximal fast charging speed by preparing and managing battery and cooling systems before and during charge events

• Design and develop features that maximizes EV range and provide clear visibility to users to build confidence in their vehicles and make informed decisions that enhance range and battery health that includes accurately predicting remaining energy and drivable range under real-world conditions using adaptive, data-driven models

• Contribute to the architecture and integration of control algorithms into production vehicle platforms

• Collaborate with Product Management, Systems Engineering, and Functional Safety teams to define and refine performance and stability requirement for the controls

• Support the development and use of simulation tools and integration test environments

• Participate in code reviews and contribute to the overall quality and robustness of the control software stack

• Work collaboratively across hardware, software, and validation teams to resolve issues and improve system performance

Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, Controls Engineering, or a related field

• Strong knowledge of thermal systems or battery systems.

• 5+ years of experience in thermal systems control, battery thermal management, battery management, or related fields

• Deep understanding of control systems theory and real-world implementation in automotive environments

• Strong knowledge and experience with software development practices (C/C++, Python, or MATLAB/Simulink) and real-time systems

• Proven experience defining system or subsystem-level architectures and interfaces

• Familiarity with automotive safety standards (e.g., ISO 26262) and diagnostic frameworks

• Hands-on experience with hardware-in-the-loop or vehicle-level testing environments

Preferred Qualifications

• Experience with safety-critical systems and architectures

• Strong communication and collaboration skills across engineering and cross-functional teams

• Track record of mentoring or leading small technical teams
