## Description

We're looking for an exceptional engineer who loves building cloud-native applications with AI at their core. If you thrive where modern infrastructure meets intelligent software, this is your role.

What You'll Do

 * Architect and ship scalable cloud apps on AWS, Azure, or GCP (Lambda, ECS, Kubernetes) with event-driven microservices and serverless architectures
 * Build AI/ML integrations using modern frameworks while driving best practices for prompt engineering, RAG patterns, and agent orchestration
 * Lead technical architecture decisions, code reviews, and define development standards and technical roadmaps
 * Own the full stack-from pixel-perfect, accessible UI implementation to robust Django REST and GraphQL APIs
 * Build real-time features using WebRTC, WebSockets, and Server-Sent Events
 * Create and enforce engineering excellence through coding standards, comprehensive testing strategies (unit, integration, agent-based, E2E), documentation, and deployment patterns
 * Champion DevOps practices, security compliance, and CI/CD pipelines while establishing observability with APM tools
 * Lead and mentor teams through agile delivery, establishing engineering culture through technical leadership and knowledge sharing
 * Collaborate with data engineering teams on pipeline integration and consumption patterns
 * Lead production incident response, post-mortems, and evaluate emerging AI/ML tools and frameworks
 * Bridge product, design, and engineering to deliver fit-for-purpose client solutions
