Job Zusammenfassung
In dieser Rolle entwickelst du skalierbare APIs und Backend-Integrationen für Handels- und Analysesysteme, überwachst Datenflüsse, optimierst bestehende Systeme und arbeitest eng mit anderen Teams zusammen, um technische Lösungen zu implementieren.
Job Technologien
Deine Rolle im Team
- Design and build scalable, reliable APIs and backend integrations that connect trading, analytics, data science, and forecasting systems.
- Drive the architecture of suena's platform layer - from initial design decisions to production.
- Own data flows and backend automations across the platform.
- Collaborate closely with the Platform Lead, CTO, and cross-functional teams (trading, data science, modelling) to translate complex domain requirements into robust technical solutions.
- Improve and extend existing systems while keeping a clear eye on reliability, security, and performance.
- Contribute to technical standards, code reviews, and engineering practices as the team grows.
Unsere Erwartungen an dich
Qualifikationen
- You think beyond the ticket - you understand how systems connect and can make principled architecture decisions.
- Security-minded: authentication, authorization, zero-downtime deployments are familiar territory.
- Comfortable working across greenfield projects and legacy systems.
- German C1 is required for this role - we work closely with German-speaking external API partners and system integrators, and clear, direct communication in German is essential for this.
- English B2/C1 for internal collaboration.
Erfahrung
- 5+ years of backend engineering experience, with a strong focus on API design and system architecture.
- Solid Python skills (Django and/or FastAPI); hands-on experience with PostgreSQL/TimescaleDB is a plus.
- Experience with distributed/cloud-based architectures (AWS preferred), Docker, CI/CD, async workflows (Celery, Redis).
- Nice to have: Experience or genuine curiosity about energy markets, trading systems, or related domains (finance, IoT). The domain is complex - enthusiasm to learn it matters.
Unser Angebot
- Hamburg Hybrid (2-3 days/week onsite) | 70.000 - 85.000 € p.a. (40 hrs / full time) | 30 Days Vacation.
- 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.
- Team Spirit: Yoga, shared lunches, after-work fun - we support each other and keep the vibe strong, even when it's busy.
- Fair & Transparent: Clear structures, democratic decisions, and a feedback culture where your voice counts.
- Body & Mind: Urban Sports Club membership, wellbeing check-ins, and mental health support - your energy matters.
- New Office Vibes: 10th-floor office with rooftop terrace, canteen, great views, ergonomic desks, hardware of your choice, and pet-friendly!
