About the Python Developer role
A Python Developer builds applications and tools in Python, one of the most versatile languages in modern software. Depending on the team, that can mean web backends and APIs with Django or FastAPI, data pipelines and ETL jobs, automation scripts, or the service layer behind machine learning products. The common thread is readable, well-structured code that other people can maintain.
Because Python covers so much ground, the biggest mistake in postings for this role is vagueness. A Django developer, a data pipeline engineer, and an ML platform developer all call themselves Python developers, and they have very different strengths. State clearly which kind of work dominates the role, which frameworks you use, and what the developer will own.
Look for candidates who write idiomatic Python rather than another language translated into Python syntax, and who understand the practical side of the ecosystem: virtual environments, dependency management, typing, and testing with pytest. If the role touches data or ML systems, say so explicitly, since that shifts the required skill set noticeably.

Job brief
We are looking for a Python Developer to design and build the services and tools at the heart of our product. You will write clean, well-tested Python, develop and maintain APIs, integrate databases and third-party services, and automate what should never be done by hand. To succeed in this role, you should write idiomatic Python, know the ecosystem well, and care about code that your teammates can read and extend. Ultimately, you will ship reliable software that moves our roadmap forward.
Responsibilities
- Design and build backend services, APIs, and tools in Python
- Develop features using frameworks such as Django, FastAPI, or Flask
- Write clean, idiomatic, type-hinted Python with thorough pytest coverage
- Design database schemas and write efficient queries with an ORM or raw SQL
- Build and maintain integrations with third-party APIs and internal services
- Automate repetitive workflows, from data imports to deployment scripts
- Profile and optimize slow code paths and memory-heavy processes
- Review teammates' code and help maintain shared coding standards
- Package, deploy, and monitor services in staging and production
- Document services, scripts, and operational runbooks for the team
Requirements and skills
- Proven work experience as a Python Developer or backend developer using Python
- Strong command of core Python, including data structures, iterators, and error handling
- Production experience with at least one framework such as Django, FastAPI, or Flask
- Solid SQL skills and experience with PostgreSQL, MySQL, or similar databases
- Experience writing automated tests with pytest or unittest
- Familiarity with virtual environments, pip or Poetry, and dependency management
- Working knowledge of Git, code reviews, and CI pipelines
- Ability to explain technical decisions clearly to both engineers and non-engineers
- BSc in Computer Science, a related field, or equivalent practical experience
Nice to have
- Experience with asyncio and asynchronous frameworks
- Familiarity with data tools such as pandas, Celery, or Airflow
- Experience deploying Python services with Docker on AWS, Azure, or Google Cloud
- Exposure to machine learning workflows or model-serving infrastructure
