Senior Python Engineer – AI/Backend

Athens (On-site) | Full-Time

About Ademú

Ademú is an early-stage AI startup on a mission to help people communicate better — especially in difficult situations. Our platform powers real-time, AI-driven conversations through personal agents that negotiate and deliberate on users' behalf. Backed by a team with a track record of success in the Greek startup ecosystem, we're building something with the potential for massive impact.

The Role

We're looking for a Senior Python Engineer to join our team. You'll play a key role in shaping our backend architecture, building scalable APIs, and integrating with AI/LLM pipelines. If you want to see your work directly impact users, this is the place.

What You'll Work On

  • Design, build, and scale backend services using modern Python (async/await, FastAPI)
  • Own API development end-to-end: routing, validation, error handling, performance, security
  • Develop real-time, event-driven systems and streaming pipelines (Kafka or equivalent)
  • Model and evolve data schemas for relational and document databases
  • Implement secure authentication and authorization flows
  • Deploy and manage services in cloud environments with containerization (Docker/Kubernetes, AWS)
  • Apply clean, maintainable patterns (Clean Architecture, Domain-Driven Design)
  • Ship features that integrate with AI/LLM-based agentic workflows
  • Build observability practices (logging, metrics, tracing, dashboards)
  • Participate in code reviews, mentor team members, and uphold engineering best practices
  • Troubleshoot and resolve production issues quickly to ensure reliability

What We're Looking For

  • 5+ years professional backend experience with Python
  • Strong track record building secure, high-performance APIs
  • Hands-on experience with async frameworks (FastAPI, asyncio, etc.)
  • Solid understanding of event-driven/distributed systems and inter-service communication
  • Proficiency with SQL and NoSQL databases and data modeling
  • Experience with cloud-native deployments and containerization
  • Knowledge of authentication, authorization, and security best practices
  • Familiarity with observability tools and CI/CD pipelines
  • Strong testing discipline and ability to deliver reliable, maintainable systems

Nice to Have

  • Experience with LLM/agent-based systems and prompt engineering
  • Background with Kafka or other streaming/messaging platforms
  • Familiarity with data privacy, compliance, and security standards
  • Experience in early-stage startup environments

What We Offer

  • Opportunity to be an early team member with direct product impact
  • Competitive salary + potential equity participation
  • Innovative and supportive team culture
  • Significant growth opportunities as we scale
  • Chance to work hands-on with cutting-edge AI technologies and shape the future of communication
