• Work closely with product, risk and operations to translate business rules into clean, reliable code.

• Help define technical standards, code quality practices and deployment patterns.

What we’re looking for

• 5+ years of backend development experience in production systems.

• Solid understanding of distributed systems, REST APIs, queues, caching, transactions and data consistency.

• Experience with cloud platforms (ideally GCP), Docker and CI/CD.

• Bonus: experience in fintech, lending, payments, risk, or high-volume transactional systems.
