About the Company

At Avaron, you get the security of permanent employment combined with the variety of working at different customers. We place specialists across everything from tech, IT and industry to project management and business support – and whatever the assignment, you have a consultant manager who is there for you and your development.

About the Role

You will bring deep battery expertise into an MVP focused on next-life planning for used battery electric vehicles. The work sits at the intersection of battery technology, analytics, and commercial decision-making, where reliable estimates of State of Health and Remaining Useful Life help shape decisions on contract length, pricing, warranty exposure, and residual value.

You will work alongside an established team with strong data science, software, and data engineering capabilities. Your contribution is to challenge assumptions, interpret degradation patterns, and make sure SOH and RUL assessments are technically credible and usable in practice. This is a strong opportunity if you want to influence how battery insight is turned into real business decisions in an advanced automotive environment.

Job Description

• You will develop and validate SOH and RUL models for used BEVs together with analytics and engineering colleagues.
• You will interpret battery degradation using operational vehicle data and connect patterns to real-world usage.
• You will compare on-board battery health estimates with off-board model results and explain deviations.
• You will assess aging drivers such as temperature, SOC, depth of discharge, charging behavior, C-rate, load, and route profile.
• You will define limitations, confidence levels, and applicability criteria for battery lifetime estimates.
• You will translate battery health insights into practical recommendations for used-vehicle sales, leasing, warranty, and residual value decisions.

Requirements

• Relevant technical education in battery technology, electrochemistry, electrical engineering, materials science, or a similar field.
• 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 both technical and business relevance.
• Experience working with battery engineers, data scientists, and commercial stakeholders.
• Professional working proficiency in English.

Nice to have

• Advanced studies or specialization within battery systems or energy storage.
• 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.

What We Offer

• Permanent employment at Avaron AB
• Occupational pension
• Wellness allowance of SEK 5,000 per year
