- Experience with Microsoft Orleans or similar actor-based frameworks
- Familiarity with Apache Pulsar, RabbitMQ, or Kafka
- Proven experience with SQL databases, ORMs, and performance tuning
- Solid grasp of CI/CD, containerization (Docker/Kubernetes), and cloud platforms (Azure or AWS)
- Excellent written and spoken English communication skills
- Strong troubleshooting skills and ability to work independently in a remote setup
