Core Responsibilities:

• Lead the design and development of robust back-end systems using FastAPI.
• Define and maintain the technical architecture, ensuring scalability, performance and maintainability.
• Evaluate, select, and integrate AI models and APIs that best fit the project requirements (e.g., LLMs, vision, NLP, or recommendation models).
• Supervise and direct a team of developers, establish coding standards and conduct technical reviews.
• Collaborate with AI providers and product teams to ensure seamless integration of smart features.
• Drive best practices in API design, cloud deployment, security, and DevOps automation.
• Stay up to date on emerging AI technologies and frameworks to guide architectural decisions.

Technical requirements:

Basic development skills:

• Expert-level Python development (5+ years).
• Deep experience with FastAPI (asynchronous programming, dependency injection, background tasks, middleware).
• Familiarity with Pydantic, SQLAlchemy and asynchronous frameworks.
• Strong understanding of RESTful API and OpenAPI standards.

Integration and use of artificial intelligence:

• Proven experience integrating external AI models and APIs (e.g. OpenAI, Anthropic, Hugging Face, Cohere, Google Gemini, etc.).
• Ability to evaluate and select appropriate AI models based on functional and business needs (e.g. text generation, summarization, image recognition, classification).
• Experience orchestrating AI pipelines – agile engineering, context management, and typical fallback strategies.
• Understanding AI service architectures – latency, scalability, cost and compliance considerations.
• Familiarity with vector databases and augmented retrieval generation (RAG) concepts.
• Comfortable working with AI SDKs, APIs and webhooks.

Architecture and system design:

• Experience designing modular and scalable back-end architectures.
• Strong understanding of microservices, event-driven and API-first design patterns.
• Experience with containerization (Docker) and orchestration (Kubernetes).
• Familiarity with caching, message brokers (Redis, RabbitMQ, Kafka) and database scaling.
• Proficiency in both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis) systems.

DevOps and Cloud:

• Hands-on experience with CI/CD pipelines and GitHub actions.
• Understanding cloud environments (GCP).
• Familiarity with Infrastructure as Code tools (Terraform, Ansible).
• Knowledge of monitoring and observation tools (Prometheus, Grafana, ELK).

Leadership and communication

• 3+ years of experience leading software teams or technical projects.
• Strong architectural vision – ability to design and communicate high-level solutions.
• Skilled in translating business objectives into technical strategies.
• Excellent interpersonal and mentoring skills.
• Restful code operation reviews, technical planning, and architecture discussions.
• Experience working in Agile/Scrum environments.

Nice to have:

• Hands-on experience integrating multiple APIs for AI vendors (e.g., OpenAI, Hugging Face, Replicate).
• Experience with AI-based applications such as chatbots, document analyzers, or recommender systems.
• Awareness of legal and ethical considerations related to AI (data privacy, model bias, compliance).
• Contributions to open source Python/FastAPI or AI integration projects.
