Required:

• 5+ years of experience in a software development role using PHP.

• Strong communication skills and the ability to explain complex technical solutions in a simple manner to others.

• Expert knowledge of OOP, SOLID principles, different design patterns, and how to apply them in a practice.

• Understanding of distributed systems design - including asynchronous tasks, event driven architecture, scheduling, caching, and queue processing.

• Experience working with high-performance systems, and solving complex engineering problems at scale (our platform processes more than 1 billion messages per day).

• Experience mentoring other developers.

Preferred:

• Experience with Pulsar or Kafka (or similar streaming platforms), and Clickhouse.

• Front-end experience with Vue.js.
