Job detail for Signal Processing & Data Engineer

Join the battery cell data revolution⚡ Location: Chemnitz (onsite preferred, hybrid possible) · Position: Full-time · Start: As soon as possible Who We Are 🌍 Limatica measures what batteries whisper. We turn the tiny voltage noise of battery cells into a quality verdict, far faster than conventional tests, and help cell manufacturers cut scrap. We are a team of twelve in Chemnitz and Munich, spanning data, ML, HPC, hardware and . Early adopters across Europe and Asia already use our technology. In 2026 we move from pilots to production lines, and our data grows faster than our team. What You'll Do 🔧 Our measurement stations produce several hundred GB of high-resolution voltage data per hour. You own the step from raw signal to reliable answer. • Work with novel cell noise data: Derive features from raw time series that make physical sense that hold up in production • Build for streaming: Design feature computations that work in streaming mode, at a throughput of up to 10,000 measurements per hour. • Make throughput a design decision: Build modular, parameterizable nodes for our distributed processing pipeline and help bring them into our Rust-based production environment. • Ship modules, not scripts: Automate evaluations end to end, from raw data to reports for our engineering team and our customers. • Own customer projects technically: Assess requirements, communicate interim results and findings, and turn feedback into improvements. What You Bring 🕵️ • Measurement experience: A degree in electrical engineering (or comparable) and 3+ years with real-world measurement data. Sampling, noise, filtering and artifacts you know from practice, not just lectures. • Physical intuition: You can explain why a feature makes sense, and you prefer a simple, well-understood method over a model nobody can explain. • Data at scale: You think in throughput: data formats, intermediate results, distributed and cached processing. • Clean engineering: Python, Git, tests and CI/CD as a matter of course. No Rust expertise needed, but the will to learn it. • Customer confidence: Fluent German and English, written and spoken. You explain results clearly to engineers and managers alike. Why Limatica 🚀 • Real ownership: Your own part of the pipeline and your first customer project within months. As we grow, this role can grow into technical lead. • Learn what few get to learn: , Rust in production and data engineering at scale, with real cells and international manufacturers. • Share the upside: Salary package including virtual stock options. • Invest in yourself: Additional holiday for personal learning • Flexibility & wellbeing: Flexible hours, hybrid work, further benefits via Guud Card and free beverages What it's like here: You get a lot of trust and a lot of room to shape things. We look for people who stay with a problem until it's solved and who enjoy the moments when a customer launch needs the whole team. Those are the moments where people here grow fastest. This role is intentionally a towards-senior position. You will take on increasing responsibility for pipeline modules and customer projects. Those who help shape the architecture and lead projects independently grow into a senior role with us.
