WHERE ELECTRIFICATION MEETS DATA-DRIVEN LIFECYCLE DECISIONS

At Multiply, we work at the intersection of embedded systems, electrification, and data-driven engineering. As part of our growing

focus on battery intelligence and lifecycle optimization, we are now looking for a Battery Systems Engineer with deep expertise in

Li-ion batteries.

In this role, you will contribute to building next-generation capabilities for assessing battery health and lifetime, enabling

smarter decisions across the lifecycle of electric vehicles—from first use to second-life applications.

You will work closely with experts in data science, software, and engineering, bringing critical domain knowledge to ensure that

battery insights are technically sound, interpretable, and actionable.

---------------------------------------------------------------------------------------------------------------------------------

WHAT YOU WILL DO

Develop and validate methods for State of Health (SOH) and Remaining Useful Life (RUL) estimation for Li-ion batteries
Analyze real-world vehicle and battery data to understand degradation behavior over time
  • Interpret and explain battery aging based on factors such as:
  • Temperature
  • State of Charge (SOC)
  • Depth of Discharge (DoD)
  • Charging patterns and C-rate
  • Load profiles and usage conditions
Compare and evaluate on-board BMS health estimates vs. off-board analytical models
Define confidence levels, limitations, and applicability of lifetime predictions
Collaborate with cross-functional teams to ensure models are physically grounded and credible
  • Translate battery health insights into practical recommendations for:
  • Lifecycle planning
  • Residual value and risk assessment
  • Warranty and service strategies
  • Second-life and reuse scenarios
---------------------------------------------------------------------------------------------------------------------------------

WHAT WE ARE LOOKING FOR

Strong background in Li-ion battery technology and degradation mechanisms
  • Experience with battery lifetime assessment, including:
  • Calendar aging
  • Cycle aging
  • Real-world usage effects
  • Deep understanding of:
  • SOH and RUL
  • Capacity fade and resistance increase
  • Performance degradation in field conditions
Experience working with battery data from vehicles, BMS systems, or testing environments
Ability to critically evaluate models and challenge assumptions
Experience collaborating with data scientists, engineers, and business stakeholders
Strong communication skills—able to explain complex battery behavior clearly
---------------------------------------------------------------------------------------------------------------------------------

MERITING EXPERIENCE

Experience with battery systems in electric vehicles (BEVs)
Exposure to second-life, residual value, or warranty risk analysis
Experience comparing BMS estimates with external models
Basic ability to work with Python, SQL, or similar tools
Background in high-utilization or commercial vehicle applications
---------------------------------------------------------------------------------------------------------------------------------

EDUCATION

Degree in electrochemistry, battery technology, electrical engineering, materials science, or similar
Advanced studies within energy storage systems are a plus
---------------------------------------------------------------------------------------------------------------------------------

WHY MULTIPLY

Work on real-world electrification challenges with direct impact on sustainability and lifecycle efficiency
Combine deep engineering knowledge with data-driven decision-making
Collaborate in cross-functional teams spanning software, data, and systems engineering
Contribute to building scalable capabilities for next-life battery use and optimization
