Your Role

• Apply battery expertise end-to-end. You lead real projects from onboarding and commissioning through designing, validating, and deploying analytics that operators rely on every day. Working with live BMS/PCS/EMS time-series, you turn raw signals into reliable diagnostics and measurable outcomes for grid-scale storage and fleets.
• Work hands-on with customers. You collaborate closely with Customer Success and Product to understand systems, diagnose issues, and configure analytics so the platform feels tailor-made to each customer and asset. The feedback loops are short, the impact is visible, and you see your decisions land quickly in the field.
• Design custom analytics and innovate. You bring a creative, solution-oriented mindset to show customers the value of cloud diagnostics, dig into technical problems, and shape the industry with fresh ideas. From lifetime prediction and state estimation to power-electronics functionality and continuous monitoring of limits, exceptions, or sensor health: You design analytics that deliver real impact in the field.
• Own delivery and improvement. You take responsibility for technical feasibility, smooth integrations, and continuous improvement, whether it's a one-off commissioning or a large system rollout across a fleet.

Your Skills

• Battery systems (Li-ion/BESS). You understand BMS signals, sensor behavior, and system architectures, and ideally bring familiarity with power-electronics and inverter behavior to connect analytics with operational realities.
• Applied mindset. You bridge models and messy data, adapting methods to real-world constraints without losing rigor, and you can explain trade-offs clearly to both technical and non-technical stakeholders.
• Software & data. You're confident with Python and Git and comfortable with time-series data from cleaning and feature engineering to efficient pipelines; experience with cloud platforms and large-scale datasets is a plus.
• Customer focus. You communicate clearly, collaborate well across teams, and consistently translate analytics into operator value and actionable decisions in the field.
• Language. You are fluent in English; German is a plus.

Our Offer

• Impact: See how your input generates direct value for the energy and mobility transition around the world.
• Shape your role: Actively shape this role and its scope with us, depending on your expertise and preferences.
• Never stop learning: Personal development plan and budget that you can actively shape.
• Devices: Powerful hardware and working environment/IDE of your choice.
• Carnival: We love carnival. That's why we're giving you Rose Monday as an extra day of holiday. ALAAF!
• Work-life-balance: Trust-based, flexible working hours, 30-day vacation entitlement.
• Remote or office based: It's your choice - either work from our lovely office in Aachen, choose a co-working space wherever you live or work from home (somewhere in Europe).
• Company events: Two 5-day company onsites per year + (remote) team events.
• A job that shapes the future and turns our planet greener one battery at a time.
