Do you want to help build the finance backbone of a company that’s enabling batteries and renewables to power our grids, and be the one who makes sure the numbers add up? Join suena energy as Working Student (f/m/x) – Finance Operations and help us build a finance and controlling setup that keeps pace with our growth. Expect a real mix: deep dives into market and trading data alongside the hands-on work that keeps Finance running smoothly.
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.
We’re a 60+ 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 Finance so it can grow with the business.
Your mission
- Analyze data and make sense of it – from market and trading data to finance figures, you help us understand what the numbers are telling us.
- Make sure our numbers are right – spot errors, question inconsistencies and help set up checks that catch them early.
- Build smart Excel solutions – that make everyday work easier and faster.
- Support day-to-day finance operations – invoices, billing, data maintenance and pre-coding in DATEV.
- Bring your own ideas – think along and suggest how things could work better.
- Support other projects in the team – depending on capacity, with insights into areas beyond Finance.
Your profile
- Advanced Bachelor’s or Master’s student in business or economics – ideally with a focus on finance, accounting or a related field.
- You catch what doesn’t add up – when a number looks off, you dig in instead of passing it on.
- You enjoy the mix – a complex data analysis one day, cleaning up invoices the next, and you take both seriously.
- Confident in Excel – and you’d rather build a better process than repeat the same manual steps every month.
- First experience with DATEV – a plus, not a requirement.
- Fluent English – our working language. German is a plus, not a requirement.
- Based in or around Hamburg – especially during onboarding, you’ll be in the office more than once a week, so a short commute matters.
