* Establish clear API contracts between Python/TensorFlow and C# services.
* Productionize ML Workflows:
* Convert research code into robust, testable, and observable services.
* Implement CI/CD pipelines, automated testing, and reproducibility standards.
* Integration & Interoperability:
* Design REST/gRPC endpoints for cross-language communication.
* Ensure compatibility with C#/.NET services.
* Performance & Scalability:
* Optimize GPU/CPU utilization, batching strategies, and memory management.
* Plan for multi-model and multi-tenant scenarios.
* MLOps & Lifecycle Management:
* Implement model versioning, artifact registries, and deployment workflows.
* Set up monitoring, logging, and alerting for solver performance.
* Security & Compliance:
* Apply best practices for secrets management, dependency scanning, and secure artifact storage.
Required Skills & Experience
