• Write robust, efficient, and maintainable code and implement best practices for code reviews, testing, and continuous integration & delivery.
• Provide technical leadership and share knowledge with less experienced engineers and foster a culture of continuous learning, collaboration, and innovation.
• Continuously monitor and improve the performance of backend services using Grafana, Prometheus, ELK, and Sentry.
• Participate in our cross‑team “squads”, providing innovative solutions and improvements to our frontend (React, Zustand, Module federation, monorepository orchestrated with NX) or backend (Grafana, Kibana, PostgreSQL, AWS, RabbitMQ, Kafka, Django, Django Rest Framework) stacks, advocating for best practices.

You would be great fit if you have

• You have substantial experience in any current Object‑Oriented backend language (familiarity with Python and Django is a plus)
• You have some experience with ReactJS (or any modern front‑end framework)
