• Proven ability designing and operating APIs, webhooks, or asynchronous messaging systems (e.g., Kafka, queues).
• Experience with languages and technologies relevant to our stack such as Java, TypeScript/JavaScript, RESTful services, SQL/MySQL, and data pipelines.
• A solid understanding of integration challenges, including data transformation, schema evolution, retries, and failure management.
• Experience leading technical workstreams and mentoring less senior engineers.
• Strong communication skills and the ability to work with cross‑functional partners.

Nice to Have:
