Team Leader / Software Architect (Python, FastAPI, AI Integration)

Core Responsibilities:

• Lead the design and development of robust backend 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 project requirements (e.g., LLMs, vision, NLP, or recommendation models).
• Supervise and mentor a team of developers, setting coding standards and conducting technical reviews.
• Collaborate AI providers and product teams to ensure smooth integration of intelligent features.
• Drive best practices in API design, cloud deployment, security, and DevOps automation.
• Stay up-to-date with emerging AI technologies and frameworks to guide architectural decisions.

Technical Requirements:

Core Development Skills:

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

AI Integration & Utilization:

• 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 — prompt engineering, context management, and model fallback strategies.
• Understanding of AI service architectures — latency, scalability, cost, and compliance considerations.
• Familiarity with vector databases and retrieval-augmented generation (RAG) concepts.
• Comfortable working with AI SDKs, APIs, and webhooks.

Architecture & System Design:

• Experience designing modular, scalable backend architectures.
• Strong grasp 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 & Cloud:

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

Leadership & Communication

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

Nice to have:

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