Were looking for Python Engineers to join our team who like working in a dynamic product environment and taking ownership of their features.

• Most of your work will be on backend services written in Python (mainly Django) with PostgreSQL as the primary database and a focus on welldesigned APIs and integrations.

• Youll be adding new features but also spending time understanding and improving existing parts of the system including performance reliability and overall developer experience.

• Some tasks are straightforward others require digging into how things currently work dealing with evolving requirements and finding pragmatic wellreasoned solutions.

• Youll take part in code reviews and technical discussions and contribute to how we design and evolve our systems including decisions around architecture tradeoffs and handling technical debt.
