Do you want customers to feel well taken care of — and be the person who makes that happen? Join suena energy as (Junior) Customer Success Manager (f/m/x). Customer Success is what keeps our customers close and confident — the foundation for partnerships that last and grow — and the single channel that routes every request internally, so the rest of the team stays focused instead of being pulled in every direction.
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 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 Customer Success is next: over the past months, Lars built the function from scratch, and now we're adding a junior and a regular CS to turn it into a real team.
You'll hear back from us within 5 working days of your application. We value your time and want to make the process as transparent as possible. Once we receive your application, we'll send you a confirmation email outlining the next steps and what you can expect from our interview process.
We can't wait to meet you!

- Keep the operational backbone running – ticketing, HubSpot, and our data room (Dock), clean and up to date.
- Take customer questions and route them internally – the "travel agent" who gets every request to the right people fast.
- Support onboarding – ensure a smooth handover from Sales and give new customers a clear picture of what happens next.
- Prep and grow into running QBRs – pull the data together with Data Science and show customers how their asset is performing.
- Work hand in hand with Sales and Ops – the glue that keeps everyone coordinated.
- Shape a function that's still taking form – spot what's unclear, sharpen processes, bring your own ideas.
- Junior starts behind the scenes – you support the team first, then grow into your own book: customers, QBRs, and KPIs (net retention, customer satisfaction).
- Junior: early in your career — we care most about how you work (organized, curious, reliable) and your drive to grow into the customer and technical side.
- Regular: you've worked with customers before and can own accounts, run QBRs, and read technical data confidently from early on.
- You can read the numbers and make them make sense – you understand a performance dashboard and explain it to a customer in plain language.
- Calm, warm, and real – our customers are engineers and asset operators; they trust substance, not a sales show.
- Organized and reliable – you keep track of what's open and don't let things slip.
- Up for building, not just running – you see an unfinished CS function as a plus, not a problem.
- A genuine team player – you pull the same rope with Sales and Ops.
- German at C1 or native level, plus solid English (B2) – most customer communication runs in German; English is our internal working language.
- Energy background? A plus, not a requirement – excitement for the industry and a fast ramp-up matter more.
- People at the Core: Clear structures, democratic decisions, and a feedback culture where your voice counts.
- Shape the Future: Contribute to the energy transition by working on sustainable energy solutions in a growing market environment.
- Connecting & Co-Creating: Strategy off-sites and onsite weeks for real collaboration and shared ideas.
- Work Your Way: Home office and flexible hours – you know what works best for you and your team.
- Good Vibes: Yoga, shared lunches, after-work fun – we keep the energy up, even when it's busy.
- Body & Mind: Urban Sports Club membership, wellbeing check-ins, and mental health support – your energy matters.
- New Office: 10th-floor office with rooftop terrace, canteen, great views, ergonomic desks, hardware of your choice, and a pet-friendly environment.
- Sustainable Extras: Deutschlandticket, FutureBens, and more – supporting your mobility and future.
