• Familiarity with Kafka and database migrations (e.g. CockroachDB to RDS) as a plus
• Strong communication, collaboration, and problem-solving skills
• The ability to thrive in an agile, iterative environment while delivering continuous feature improvements
• Experience mentoring mid-level engineers and modelling engineering best practices
