• Familiarity with containerization (Docker), CI/CD pipelines, and cloud environments (AWS preferred).

• Good understanding of distributed systems fundamentals (timeouts/retries, idempotency, eventual consistency) and scalable design patterns.

• Clear communicator who collaborates effectively across disciplines and helps grow technical capability through mentorship.

Preferred qualifications

• Experience with Swoole, Laravel Octane, or other PHP performance optimization platforms.

• Exposure to event-driven systems and messaging platforms (Kafka or similar) and analytical stores such as ClickHouse.
