Low Voltage Electrical Energy Management Systems Engineer

Job Description

The Role
The Low Voltage Electrical Energy Management Systems Engineer helps define and optimize how low‑voltage (12 V & LV) electrical power is used in our vehicles. In this role, you will blend systems engineering, data analysis, and testing to understand 12 V loads, support energy and performance targets (range, emissions, robustness), and improve tools and methods used across multiple vehicle programs.
You will be a key technical contributor in a small, focused team that uses virtual models, standardized databases, and measured data as primary decision tools. The work is highly interdisciplinary, connecting electrical, thermal, controls, and vehicle performance perspectives to deliver low‑voltage insights that guide content, feature behavior, and system sizing.

What You’ll Do
12V Load Modeling & Analysis

• Build and maintain low‑voltage load models and estimates for key driving and customer‑use scenarios (on‑cycle and off‑cycle).
• Develop and maintain 12 V load estimates and duty cycles for important vehicle use cases, using schematics, fuse/load charts, databases, and physical measurements.

• Incorporate variation, temperature effects, and realistic worst‑case usage into 12 V assessments so sizing and robustness decisions are grounded in real‑world behavior.

• Document models, assumptions, and intended usage so partners understand how to apply results and where the limits are.

Off‑Cycle and “Off‑Power” Use Cases

• Support off‑cycle and “off‑power” scenarios (e.g., parked usage, charging, short‑term customer interactions, post‑event cases) by helping define realistic electrical usage patterns and constraints.

• Translate customer and program needs into clear low‑voltage use‑case definitions that support system sizing, robustness, and energy targets.

System Integration & Requirements

• Contribute to requirements and verification plans for low‑voltage behavior, and support execution of bench and vehicle tests that confirm those requirements.
• Provide clear low‑voltage status and trends to partner teams so they can make informed decisions about features, content, and efficiency.
• Act as a systems‑engineering contact for 12 V Load Management, helping connect feature behavior, architecture, and analysis into a coherent story.

• Work with cross‑functional teams (energy, thermal, electrical infrastructure, vehicle performance) to identify and close gaps in data hand‑offs, ownership, and responsibilities related to low‑voltage systems.

Data, Tools, and Automation

• Help improve the data, tools, and workflows used to manage 12 V loads, for example by automating recurring analyses or improving how results are stored and shared.
• Use data‑analysis methods to gain insights from 12 V measurement and database data, identifying trends, issues, and optimization opportunities.

• Contribute to the evolution of central low‑voltage databases and reports so that information is accurate, traceable, and reusable across programs.

Your Skills & Abilities (Required Qualifications)

• Bachelor’s degree in Electrical, Mechanical, Aerospace, Computer, Systems Engineering, or a closely related technical discipline.
• Experience working with vehicle electrical systems or similar low‑voltage power‑distribution problems.
• Solid understanding of electrical fundamentals: loads, fusing, duty cycle, basic sizing, and how they relate to system robustness and customer usage.
• Demonstrated ability to analyze complex technical data (measurements, databases, or simulations) and translate it into clear, actionable recommendations.
• Strong problem‑solving skills, with examples of structuring ambiguous technical problems into concrete analysis and next steps.
• Effective written and verbal communication, including the ability to explain low‑voltage findings to partners who are not electrical specialists.
• Comfortable working in a cross‑functional environment, balancing inputs from multiple teams and managing competing priorities.

What Will Give You a Competitive Edge (Preferred Qualifications)

• While not required, experience in the following areas will strengthen your candidacy:
• Advanced degree (MS or greater) in Electrical, Mechanical, Systems, or related Engineering.
• Experience in vehicle energy, range, or emissions analysis, especially related to accessory loads or electrical architecture.
• Hands‑on experience building or maintaining engineering databases, dashboards, or analytical workflows used as “gold sources” across teams.
• Familiarity with systems‑engineering practices such as requirements management, DFMEA, and verification & validation planning.

• Experience using data and modeling tools such as:

• Python, MATLAB, Power BI, or DataBricks for analysis and visualization.
• Physics‑based or circuit‑simulation tools (e.g., COMSOL, MATLAB/Simulink, SABER, PyBaMM, or similar) to model electrical or electro‑thermal behavior.

• Demonstrated ability to improve or automate existing analysis processes, reducing manual effort while increasing transparency and repeatability.
