• You value dedicated teamwork, respect, and curiosity, as well as navigating communication in cross-functional, culturally diverse environments.
• Engineering excellence is your pursuit, demonstrated by your solid understanding of back-end languages and web frameworks like Django.
• You are not content with the status quo and consistently seek innovative solutions to existing problems, with a commitment to personal and collective growth.

What you'll need:

• Ambition to be consistently testing and optimizing code and queries.
• Enough professional experience that positions you to be flexible, reliable and move quickly.
• Proficiency in Python and a recent web framework.
• Professional experience with Django – this means true professional experience. You understand how to optimize; you understand its shortcomings; you are able to build and structure things intuitively. Otherwise, the desire and ability to learn quickly.
• Knowledge of different database systems — we use Postgres and Clickhouse.
• An eye for security practices.
• Familiarity with product and design lifecycles, collaborating with designers and product managers.
• Proven ability to write high-quality, well-tested, and maintainable code.
• Familiarity with current trends and best practices.
• Excellent communication skills and ability to work in a fast-paced environment.

Nice to have:

• Familiarity with Celery, Redis, React.
• Dev ops experience — we have automated pipelines that build ECS clusters.
