Backend / Data Platform Engineer (AWS & Analytics) (m/f/d)GröbenzellLocation: Gröbenzell Start: effective immediately or laterWe are revolutionizing hydropower through providing an important form of base-load, regenerative energy generation – as this is the only way the renewable energy goals can be reached!We are the first to succeed in generating clean electricity locally without ecological disadvantages. Our solution is the Energyfish – a scalable micro hydro power device that can simply be suspended in a river system and generates electricity from the kinetic energy in flowing water. By combining hardware, software, and data, we are building a new generation of decentralized energy systems.What you'll do:Design and build backend systems for processing and analyzing device dataDevelop data pipelines that transform raw inputs (e.g. CSV, time-series data) into KPIs and aggregated metrics, anomaly detection and trend analysis, and structured outputs (JSON, reports, visualizations)Work with AWS services such as Lambda, S3, and related toolsMake architectural decisions around data modeling and storage formats, pipeline design (batch vs. streaming), and performance and cost optimizationEnsure systems are reliable, idempotent, and easy to evolveContribute to product-level decisions around analytics and reportingWhat we're looking for:Degree in Computer Science, Software Engineering, or a related field (or equivalent experience)Strong backend development skills (Python or similar)Experience building systems on AWS (e.g. Lambda, S3)Experience with data processing or pipeline developmentAbility to design systems and make architectural decisionsStructured and pragmatic approach to problem solvingNice to have:Experience with time-series data or analytics systemsFamiliarity with Parquet or columnar storage formatsExperience with orchestration toolsInterest in data-driven products and real-world datasetsWhat we offer:The opportunity to work on live, connected power systems, not just dashboardsA role where your work directly supports the renewable energy transitionFlat hierarchies, open communication, and full-stack ownershipHybrid work possible from our office near Munich (Gröbenzell)30 vacation days and flexible working hoursJ-18808-Ljbffr
