We leverage cutting-edge Artificial Intelligence (AI) and Machine Learning (ML) algorithms to develop solutions for automated document processing and customer service chatbots. We are looking for Sr AI Engineers with strong engineering, and full stack expertise to evaluate new Large Language Models (LLMs) and make them available for the enterprise in a compliant and secure manner. The work you do will impact millions of customers, members, and employers who rely on Cigna every day. Extreme focus on speed to market and getting Products and Services into the hands of customers and passion to transform healthcare are key to the success of this role.

Responsibilities :

- Build enterprise-grade AI solutions with a focus on privacy, security, and fairness.

- Comprehensive understanding of cloud computing principles, services (such as resource pooling, rapid elasticity, measured service), and architectures(microservice and serverless) from major cloud providers (e. g., AWS, Azure, Google Cloud, OpenShift).

- Design and implement solutions leveraging OpenShift's features for container orchestration or using AWS services -Sagemaker, S3 Lambda, and EC2 to configure LLMs.

- Test the latest LLMs using standard evaluation criteria and make the LLMs available for enterprise use, with the right security, authentication, logging, and monitoring.

- Efficiently managing cloud resources to optimize performance and cost.

- Architect and develop software or infrastructure for scalable, distributed systems and machine learning technologies.

- Work with frameworks(Tensorflow, PyTorch) and open-source platforms like Hugging Face to deliver the best solutions.

- Optimize existing generative AI models for improved performance, scalability, and efficiency.

- Develop and maintain AI pipelines, including data preprocessing, feature extraction, model training, and evaluation.

- Develop clear and concise documentation, including technical specifications, user guides, and presentations, to communicate complex AI concepts to both technical and non-technical stakeholders.

- Contribute to the establishment of best practices and standards for generative AI development within the organization.

Requirements :

- 5 years of Full stack engineering expertise with languages like C#, and Python and Proficiency in designing architecture, building API Integrations, configuring and deploying cloud services, setting up authentication, monitoring, and logging

- 3 years of experience in a technical leadership role leading project teams and setting technical direction.

- 3 years of experience working in a complex, matrixed organization involving cross-functional or cross-business projects

- Experience in implementing enterprise systems in production settings for AI, computer vision, and natural language processing.

- Exposure to self-supervised learning, transfer learning, and reinforcement learning is a plus.

- Experience with information storage/retrieval using vector databases like Pinecone.

- Experience with designing scalable software systems for classification, text extraction/summary, and data connectors for different formats(pdf, csv, doc, etc)

- Experience with machine learning libraries and frameworks such as PyTorch or TensorFlow, Hugging Face, Lang chain, and Llama Index.
