• Apply AI techniques to integration challenges such as transactional anomaly detection, intelligent event classification, and data enrichment
• Integrate LLMs and AI services into existing architecture while maintaining deterministic fallback behavior
• Ensure AI solutions meet production standards for security, observability, cost control, and reliability

Observability & Operational Maturity

• Experience implementing and operating logging, metrics, tracing, and alerting systems (Prometheus, Grafana, or similar)
• Proven ability to diagnose issues across ERP systems, integration services, and downstream data platforms
• Experience supporting production environments with strong ownership mindset

• Bachelor's degree in computer science
• 4–8+ years of experience building and operating backend systems in production environments
• Experience with backend or integration service development using Java or similar programming languages
