Quick Check: Is this your kind of engineering challenge?

• 
  
• Tech Stack: Python (Django/FastAPI), PostgreSQL/TimescaleDB, Redis, Celery, Docker, AWS, GitLab CI/CD, Sentry, Grafana
• Your Focus: API design & architecture, backend integrations, data flows, system reliability and scalability
• Team: Small, newly formed platform squad — you'll work closely with the Platform Lead, with strong support from our CTO in the early phase
• Product: Real-time energy trading platform — high complexity, data-heavy, ML-integrated
• Who thrives here: Engineers who think in systems, take ownership, and are energized by building things that actually matter
• Must-haves: 5+ years backend experience, solid API & architecture background, Python, cloud deployment, German C1
• Dealbreakers: No API/architecture experience, pure CRUD background, no interest in complex distributed systems

Your mission

• 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, modeling) 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

Your profile

• 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)
• 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
