• Contribute to shaping our engineering culture and establishing high standards for quality, ownership, and collaboration.

• Solid experience (5+ years in backend engineering, 3+ years with Python) in designing clean, versioned, and developer-friendly REST APIs.
• Strong fundamentals in distributed systems, including asynchronous processing, queues, idempotency, retries, and designing for failure.
• Proficiency in relational database modelling (PostgreSQL or MySQL), covering indexing, query performance, and schema evolution under load.
• Comfort working in cloud environments (GCP, AWS, or Azure) and implementing reliable CI/CD pipelines.
• Alignment with our corporate culture and a commitment to integrity and ethics are highly valued;
• Strong customer focus, teamwork, task prioritisation, and daily commitment are highly appreciated.
