What will you bring to the team?
- Experience: Strong experience in Backend Engineering or Data Engineering, with a proven track record of deploying production-grade pipelines.
- Technical Stack:
- Strong mastery of one programing language , scala or go would be a plus
- Hands on experience with Kafka, Redpanda, Aerospike, C* or any big data production ready component

- Engineering Mindset: You are obsessed with performance, code quality (CI/CD), and system architecture.
