Responsibilities

  • Full Stack Development Design and develop scalable, high-performance applications using.NET (C#), ASP.NET Core, and REST/GraphQL APIs.
  • Build responsive, intuitive frontend interfaces using React, Angular, or Blazor.
  • Ensure application security, performance, and code quality through design reviews, unit testing, and CI/CD best practices.
  • Build and maintain ML pipelines using Amazon SageMaker, MLflow, or AWS Step Functions.
  • Implement RAG (Retrieval-Augmented Generation) architectures, vector databases (Pinecone, Weaviate, Amazon OpenSearch), and embedding models.
  • Monitor model performance in production, manage model drift, and implement retraining workflows.
  • Collaborate with data engineers to ensure high-quality feature engineering and data availability.
  • Cloud & DevOps Deploy and manage applications on Amazon Web Services (AWS) - including EC2, ECS/EKS, Lambda, S3, and API Gateway.
  • Build and maintain CI/CD pipelines using AWS CodePipeline, GitHub Actions, or Jenkins.
  • Implement infrastructure-as-code using Terraform or AWS CloudFormation / CDK.

Requirements

  • 8+ years of software engineering experience with at least 4+ years focused on.NET (C# / ASP.NET Core).
  • Practical experience integrating LLMs and generative AI capabilities into production applications.
  • Strong proficiency with frontend frameworks - React, Angular, or Blazor.
  • Strong experience with AWS cloud services (SageMaker, Bedrock, Lambda, ECS/EKS, S3, RDS, DynamoDB).
  • Proficiency with SQL and experience with NoSQL data stores.
  • Hands-on experience with Git, CI/CD pipelines, and Agile development methodologies.
  • Strong problem-solving skills and ability to work independently in a fast-paced environment.

Nice to have

  • Experience with MLOps frameworks (MLflow, SageMaker Pipelines, SageMaker Model Registry).
  • Familiarity with vector databases and RAG-based architectures.
  • Exposure to prompt engineering, fine-tuning, or LLM orchestration frameworks (LangChain, Semantic Kernel, AWS Bedrock Agents).
  • Knowledge of financial services or banking domain.
  • AWS certifications (Solutions Architect, ML Specialty, or Developer Associate) are a plus.
  • Experience with containerization (Docker, Kubernetes / Amazon EKS).
  • The ideal candidate bridges the gap between traditional enterprise software development and modern AI/ML systems, delivering end-to-end solutions from data pipelines to production-ready user interfaces.
  • Architect microservices and event-driven systems using Amazon SQS, SNS, Kafka, or RabbitMQ.

Skills

  • Integrate with relational (SQL Server, PostgreSQL, Amazon RDS) and NoSQL (MongoDB, DynamoDB) databases.

Benefits

  • AI / ML Engineering Design, develop, and deploy machine learning models for use cases such as classification, regression, anomaly detection, recommendation, and NLP.
