Join Unbound Potential (UP): a Swiss startup founded in 2023 by a team of passionate engineers, chemists, and economists from ETH Zürich.
We envision a resilient, electrified society, one that is not only independent from fossil fuels, but also free from critical mined materials like lithium and vanadium. How will we get there? By developing a disruptive, innovative solution: a membrane-less redox flow battery powered entirely by organic chemistry. Despite the name, our system is one of the simplest large-scale stationary energy storage solutions imaginable - scalable, cost-effective, and sustainable - perfect for energy-intensive industries and utilities.
We are currently expanding our excellent team of disrUPtors and looking for exceptional talent to join our mission. If you’ve ever been truly passionate with something - tech, academia, sport, art - and pushed yourself to the edge of excellence, you know what it takes. That’s what we care about. We’re building a team of dreamers and builders who are all-in on doing something unique and making a meaningful impact on society.
If you feel that same urgency and ambition to shape a better world: you belong here.
About the job:
We are seeking an experienced Battery Engineer with a strong passion for energy storage, system-level electrochemistry, and the real-world impact of their work. In this role, you will focus on developing testing protocols for our next-generation redox flow batteries. You will work closely with the engineering team responsible for designing the cells and system, translating electrochemical test results into robust KPI data sheet and actionable performance metrics.
This role is ideal for someone with strong foundation in fundamental electrochemistry and has hands-on experience in testing energy storage systems - from a single cell, to stacks/packs, and up to a full system level validation.
What you will do:
- Develop and conduct internal electrochemical testing protocols for the fundamental characterization of: electrolytes (including pre- and post-mortem analysis), electrodes or BPPs (including corrosion tests).
- Develop and execute testing protocols for a single cells and stacks, including studies on the influence of flow rate, current density, SOC, and capacity utilization.
-
Develop and perform system-level testing protocols, including evaluation of RTE.
- Design and conduct long-term stability and accelerated aging tests, including the use of climatic chamber.
- Optimize operational conditions of membrane-less redox flow batteries to minimize self-discharge, and maximize CE and VE.
- Validate and execute testing protocols for SOC and SOH monitoring at the system level (including usage of the OCV cells and other electrochemical techniques).
What you will bring:
- Experience in energy storage system testing (RFB, Li-ion, FC).
- Degree (MSc or PhD) in Chemical Engineering/Material Science/Physics/Chemistry with a strong foundation in electrochemistry.
- Hands-on experience with potentiostat (preferably Biologic) and battery cycler, data analysis using Python.
- Solution-oriented mindset with out-of-the-box thinking.
- Experience with good laboratory practices, physico-chemical characterization of electrolytes and materials, and setting up flow-based test set-ups.
You are
- A maker, willing to take initiative, seek solutions, and deliver tasks efficiently.
- Motivated to work in a dynamic, high-performance, collaborative, young, and fun start-up environment.
- Strongly interested in the climate-tech space.
- Independent and detail-oriented.
- Passionate about driving the renewable energy transition.
- Excellent team player.
- Fluent in English.
What We Offer?
Join a highly motivated and young team. Be at the forefront of developing the next-generation large-scale energy storage solutions. Your role in the early stages of our exciting journey will make you key in developing and evolving UP, overcoming challenges, and celebrating success together.
