• Collaborate with ML engineers to productionize models and optimize inference performance
• Develop responsive UI components that help users interact with AI intelligently and transparently
• Write clean, testable code and participate in code reviews
• Feed your application runtime data into timerseries databases (ie. Prometheus) coupled with monitoring and alerting logic (ie. Grafana) to assist with resolution of issues and outages

• Hands‑on experience with Apache Cassandra, Apache Solr and Postgres for scalable data storage
• Familiarity with real‑time or near‑real‑time data applications
• Strong communication skills and a collaborative mindset
• Passion for software systems and architecture, and eagerness to stay ahead of emerging trends
