Hamburg | Hybrid with 3 days onsite | €50.000 - €60.000 p.a. (40 hrs/week) | 30 days vacation | German / English C1 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! Drive People Operations end-to-end – maintain daily HR operations in Personio, execute contract changes, and manage parental leave, health insurance, and visa administration. Execute monthly payroll – lead hands-on coordination with our external payroll provider, process salary changes, bonuses, and benefits, and audit data to catch errors before payday. Centralize and own onboarding operations – consolidate fragmented tasks into a single, cohesive onboarding process that delivers a frictionless joiner experience. Maintain full HR compliance and safety – operationalize workplace safety, assign first-aid/fire-safety officers, enforce mandatory trainings, and keep processes fully compliant as we grow. Proactively spot and resolve operational gaps – audit details, flag inefficiencies early, and follow through to resolution before issues impact the team. Build scalable operational workflows – turn one-off edge cases into standardized, documented SOPs so processes run seamlessly and predictably as we scale. Co-own team experience and culture operations – partner with Marietta, our People Lead, to organize team rituals, manage internal communications logistics, and sustain the everyday culture that makes suena feel like suena. Deep People Operations experience – you've owned HR processes along the whole employee lifecycle, not just supported someone who did. You navigate German bureaucracy confidently – 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. 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) – company language is English, German is mandatory and required for some aspects your work. Already doing payroll, or open to growing into it? Either is fine.
