Intro Hamburg Hybrid (50/50) | 50.000 – 55.000 € p.a. (Full-time) | German C1 Do you want customers to feel well taken care of — and be the person who makes that happen? Join suena energy as 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 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 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. Your mission • 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. Your profile • Energy background – you bring relevant experience or a solid understanding of the energy trading industry and can connect the dots. • 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. Why us? • 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 or Wellpass – your choice. Plus wellbeing check-ins and mental health support via nilo.health – 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: Subsidized Deutschlandticket, JobRad, Givve Card and more – supporting your mobility and everyday life.
