Intro

Hamburg Hybrid (50/50) | 45.000 -- 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 (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.

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.
• Junior starts behind the scenes ---
  you support the team first, then grow into your own book: customers, QBRs, and KPIs (net retention, customer satisfaction).

Your profile

We're filling two seats ---
one junior, one regular. The main difference is how much you already bring:

• 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.

Either way, what counts:

• 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.

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 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.
