This analysis covers Python developer hiring patterns observed across 500+ companies tracked by Josh Smith, a specialist Python recruiter. Data is updated weekly based on active job postings, placement data, and hiring manager conversations.
Key Trends at a Glance
↑ +45% FastAPI adoption in new projects (replacing Flask)
↑ +60% Demand for AI/ML Python engineers
↑ +35% Pydantic v2 / type hints requirements in job specs
FastAPI has become the default choice for new Python API projects. Companies cite async-first architecture, automatic OpenAPI docs, and Pydantic integration as key drivers. In Q4 2025, 45% of new Python web roles specified FastAPI, up from 28% in Q4 2024.
Django Remains Enterprise Standard
Django isn't declining—it's maturing. Large enterprises and established products continue to hire Django developers, often at senior levels for maintenance and scaling. New greenfield projects, however, increasingly choose FastAPI or async alternatives.
Modern Python Tooling
The "modern Python stack" is now expected knowledge for mid-level+ roles:
Ruff: Fast linter/formatter replacing Flake8 + Black
uv: Faster package installer gaining traction over pip
pyproject.toml: Standard project configuration (PEP 517/518)
Type hints: No longer optional; most job specs require typing experience
AI/ML Hiring Surge
The AI boom has dramatically increased demand for Python developers with ML experience. Key observations:
LLM integration roles: New category of roles focused on prompt engineering, RAG systems, and LLM API integration. Salary premium: +25-40%.
MLOps growth: Companies that built ML models in 2023-2024 are now hiring for productionization. Kubeflow, MLflow, and feature store experience in high demand.
PyTorch dominance: 70% of ML roles specify PyTorch over TensorFlow. Hugging Face ecosystem knowledge is increasingly expected.
Regional Demand Shifts
United Kingdom
London: Fintech and AI startups driving demand. Senior roles £100-140k. ↑ +15%
Manchester/Bristol: Growing tech hubs with 20-25% lower salaries than London but strong quality of life. ↑ +25%
