Are you excited about owning People Operations for a team that's scaling as fast as the energy transition itself? We've got the basics – Personio's set up, some processes exist. What's missing is someone who owns it full-time, end-to-end. Join suena energy as People Operations Manager (f/m/x) and turn what's currently pieced together into something that actually scales as we grow.

suena energy is a green tech startup specializing in algorithmic energy trading for energy storage systems and renewable energies.
Our vision: a world where clean energy is used reliably, economically, and intelligently. With our AI-based optimization and trading software, we maximize the revenues of operators of large-scale energy storage and renewable assets on short-term electricity and balancing markets - while simultaneously minimizing their risks.

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 we're excited to strengthen our team with new talent and continue growing together!

• Own People Operations end-to-end – from Personio and contract changes to parental leave, health insurance, and visa topics.
• Turn one-off cases into repeatable processes – research it once, document it, and set it up so the next person doesn't start from zero.
• Centralize and own our onboarding into one process, instead of split across the team.
• Own HR compliance end-to-end – workplace safety, first-aid and fire-safety officers, mandatory trainings – and make sure we stay compliant as we grow.
• Catch what's missing before anyone has to ask – double-check the details, flag what needs fixing, follow through.
• Co-own culture with Marietta, our People Lead – team rituals, internal comms, the things that make suena feel like suena.
• Take on strategic People projects as you grow into the role, with room to develop toward HR Business Partner work.

• Hands-on People Operations experience – you've owned the employee lifecycle, not just supported someone who did.
• You navigate German bureaucracy – labor law, social security, health insurance, visa topics – and you always know what actually matters.
• Personio know-how – ideally you've set up or automated workflows in it.
• You own problems, not just tasks – you build what's missing, flag what's broken, and fix it without being asked.
• Employee-facing at heart – approachable, service-minded, and genuinely invested in how people experience working here, not just compliance from behind a desk.
• Direct communicator – you raise issues and push back when something's off.
• Fluent in German and English (C1 each) – working language is English, German law runs in German.
• Already doing payroll, or open to growing into it? Either's fine.

• 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.
