Electrical engineer - Battery Degradation and RUL Specialist

Professional Galaxy is an IT and technology consulting company that provides highly specialized expertise within IT, software development, SAP, purchasing, electronics and mechanical design. We collaborate with experienced senior experts and deliver strategic value-creating expertise to some of Sweden's most complex and analytically demanding projects. Our focus is always on high quality, professionalism and clear, measurable results.

We are now seeking an Electrical engineer - Battery Degradation and RUL Specialist for one of our clients.

About the assignment:

We are looking for a consultant with strong Li-ion battery expertise to support an MVP for used BEV next-life planning. The assignment focuses on assessing battery State of Health (SOH), estimating Remaining Useful Life (RUL), and translating battery insights into practical decisions related to contract length, pricing, warranty risk, and residual value.
The team already has strong data science, software, and data engineering capabilities. This role is therefore primarily focused on battery domain expertise—understanding degradation mechanisms, challenging model assumptions, interpreting battery health estimates, and ensuring the technical credibility of results.

Responsibilities:
• Develop and validate SOH and RUL models for used BEVs in close collaboration with the analytics and engineering team
• Interpret battery degradation based on operational vehicle data
• Compare on-board battery health estimates with off-board model results and explain deviations
• Assess key aging drivers such as temperature, SOC, depth of discharge, charging behavior, C-rate, load, and route profile
• Define practical limitations, confidence levels, and applicability criteria for battery lifetime estimates
• Translate battery health and RUL insights into recommendations for used-vehicle sales, leasing, warranty, and residual value decisions

Education:
Must Have:
• Relevant technical education in battery technology, electrochemistry, electrical engineering, materials science, or similar

Nice To Have:
• Advanced studies or specialization within battery systems or energy storage

Experience:
Must Have:
• Strong expertise in Li-ion battery technology and degradation mechanisms
• Experience with battery lifetime assessment, including calendar aging, cycle aging, and real-world usage effects
• Solid understanding of SOH, RUL, capacity fade, resistance increase, and performance degradation
• Experience interpreting battery data from vehicles, BMS systems, diagnostics, or battery testing
• Ability to critically assess battery model outputs and judge technical and business relevance
• Experience working with battery engineers, data scientists, and commercial stakeholders

Nice To Have:
• Experience with BEVs, preferably commercial vehicles or high-utilization applications
• Experience with used-vehicle battery health, residual value assessment, warranty risk, or second-life planning
• Experience comparing on-board SOH estimates with external or off-board battery models
• Basic proficiency in Python, SQL, or similar tools to review and validate analysis results

Language:
• English (working language)

Personal / Soft Skills:
• Pragmatic and analytical battery specialist
• Ability to challenge assumptions constructively
• Strong communication skills, with the ability to explain complex degradation topics clearly
• Capable of translating technical uncertainty into actionable insights for business decision-making

Other Specifications:
• The consultant is expected to contribute to making battery health insights credible, understandable, and directly usable for used BEV next-life planning decisions.
