• Set the technical vision - Own the back-end roadmap, architectural standards, and long-term scalability strategy for our cloud-native platform.
• Mentor and multiply - Coach 3-5 engineers through design sessions, code reviews, and pair programming; foster a culture of quality, observability, and continuous improvement.
• Drive cloud excellence - Evolve our AWS and EKS infrastructure for multi-tenant, multi-region resilience, security, and cost efficiency.
• Champion best practices - Introduce and refine standards for CI/CD, testing, incident response, and documentation.
• Partner across functions - Work closely with Product, Data Science, and Clinical SMEs to shape features that delight users and meet regulatory needs.

• 3+ years in a senior or tech-lead role guiding architecture and mentoring engineers.
• Deep AWS expertise
• Hands-on Kubernetes know-how: Cluster  tuning, service meshes, and runtime debugging.
