Join suena energy as Financial Controller (f/m/x) and become the analytical backbone of our Finance team – from 15-minute MWh to scenario modeling. suena energy is a green tech startup specializing in algorithmic energy trading for energy storage systems and renewables. Our vision : a world where clean energy is used reliably, economically, and intelligently - and where we actively accelerate the energy transition by enabling batteries and renewables to power our grids. With our AI-based optimization and trading software, we maximize the value and market participation of large-scale energy storage and renewable assets in short-term electricity and balancing markets - while minimizing risk for operators. Today, this kind of analysis gets squeezed in around the day-to-day – we need someone to make it a proper part of how Finance works. We're a 50+ person team that's fast-paced by nature, but the kind of place where people actually look out for each other. Following our successful Series A, we're investing in expanding our team – and building out real financial transparency as we scale. Run scenario analyses on our rolling forecast , working with Lena, our Senior Controller, on the assumptions. Pull and process raw data yourself – CSVs straight from Data Science, no waiting on a specific cut. Reconcile MWh data against power exchange settlements , interval by interval, so every number is traceable. Chase down what's off in the numbers – ad hoc, whenever something in trading or finance data needs some deep dive analysis. Tighten our Excel models – find the errors, automate the manual parts, build in checks. Surface product-level profitability for our CFO. Your track: own the MWh data analysis. automate the checks and own scenario modelling by month 3-6 You've scoped and built something yourself end-to-end in trading or an adjacent field (energy trading, commodities, prop trading, quant funds, asset management for renewables/storage) – a reconciliation logic, a forecast model, a recurring analysis you owned, not one you maintained or supported. Strong in Excel and confident in Python – you pull, clean, and work with raw data yourself, not just finished exports. You catch what doesn't add up – not just running numbers, but questioning them. Business sense over accounting depth – no tax/bookkeeping needed, but you read a PnL. No ERP, no problem – we're Excel-based across multiple sources right now. Fluent English – our working language. German's a plus. International company experience: a plus, not a must.
