đź“Ś R&D Engineer/PhD – Li-ion Batteries (M/F)
Full-time – Deeptech startup – Battery diagnostics – Nanterre
Do you have an innovative mindset and want to be part of a French startup pushing the boundaries of battery technology? Entroview is looking for passionate individuals ready to take on exciting challenges and help reshape the sustainable energy sector!
🔋 Who are we?
Entroview is a deeptech startup supported by BPI France and Grenoble INP, specializing in the development of advanced solutions to make Li-ion batteries smarter, safer, and more efficient. With our patented entropy measurement technology, we offer battery diagnostics and state-of-health predictions with unmatched accuracy.
We recently secured a significant round of funding, allowing us to accelerate our growth and strengthen our market position. This success gives us long-term visibility and the resources needed to fulfill our mission to transform the energy sector.
Since our founding in July 2021, we’ve established partnerships with industry leaders such as Northvolt and Stellantis to scale our technology. We continue to innovate with the goal of becoming a leader in advanced battery management.
🎯 Why this role is for you:
Entroview performs Li-ion cell characterization and diagnostics, particularly for State of Health (SOH), State of Charge (SOC), and end-of-line testing in factories. We work throughout the battery life cycle—from production in gigafactories to in-use diagnostics and end-of-life assessments. Our first product already enables these characterizations at the module level.
The purpose of this role is to contribute to implementing our technologies in new use cases and improve existing diagnostics.
As a battery engineer, you’ll play a key role in the development of our new solutions. At the heart of our R&D team, you’ll contribute to both internal research projects and collaborations with automotive industry partners.
đź’Ľ Your responsibilities:
- Collaborate with product development teams to continuously improve our diagnostic methods (e.g., research into reducing test times, degradation modes, etc.)
- Conduct technological monitoring of battery diagnostics and prognostics; propose and assess new diagnostic approaches.
- Develop multiphysics models for Li-ion cells and modules.
- Experimentally validate modeling results in close cooperation with the laboratory lead.
- Process and analyze data using appropriate tools (Excel, Python, etc.)
- (Optional) Contribute to the development of machine learning-based diagnostic and prognostic models, in coordination with our data science experts and industrial partners.
🧑🏻‍🎓 What we’re looking for: You hold an engineering degree with at least 2 years of experience, or a PhD, in the field of Li-ion batteries. You possess skills in materials science and/or electrochemistry applied to Li-ion batteries, ideally with a product-oriented mindset (experience at module or pack level is a plus).
You are autonomous, motivated, proactive, and ready to thrive in an applied research environment working alongside industrial partners.
🧑🏻‍🔧 Required skills:
- Strong knowledge of Li-ion batteries at the cell level
- Proficiency in programming and data analysis (Python)
- Experience in Li-ion battery performance diagnostics
- Hands-on experience with instrumentation and measuring current, voltage, and temperature
- Precision and rigor in research and documentation
🧑🏻‍🔧 Optional skills:
- Knowledge of Li-ion batteries at the module and pack levels
- Experience in multiphysics modeling (e.g., COMSOL or equivalent)
- Background in machine learning for battery diagnostics or prognostics (scikit-learn, TensorFlow, PyTorch…)
đź’Ą Why join Entroview?
- Continuous innovation: Be part of a company pushing the boundaries of technology.
- Direct impact: Contribute to projects that have a global impact on the energy transition.
- Personal growth: Thrive in a dynamic startup environment where every idea matters.
- Career opportunities: Real prospects for advancement.
- Flexible work environment: Enjoy a workplace that values work-life balance.
➡️ Salary: Competitive, based on experience and profile.
