- Experience with test-driven development and automated testing strategies.

- Strong troubleshooting and debugging skills in distributed environments.

- Excellent written and verbal communication abilities.

Nice to Have

- Experience participating in system architecture design with the ability to explain technical decisions and trade-offs.

- Proactive mindset with a desire to drive technical innovation rather than just following established patterns.

- Familiarity with DevOps practices, Linux administration, and infrastructure as code.

- Deep understanding of distributed systems design patterns and microservice architecture principles.

- Experience mentoring junior developers or participating in technical recruitment.

- Interest in sharing knowledge through technical articles, presentations, or internal workshops.

- Previous experience in the banking or financial services industry.

- Cloud platform experience (AWS, Azure, GCP).
