## Description

Mastercard is seeking a Senior AI Engineer to join the Capabilities and Data team within Mastercard Services. The successful candidate will develop and scale shared AI capabilities that support products and teams across Mastercard.

The role involves designing and owning the architecture for deploying and operating AI capabilities at scale, including APIs and MCP servers that enable integration with products, agents, and applications. The ideal candidate will have hands-on experience leading and delivering complex Gen AI or ML engineering programs in production environments.

Key responsibilities include:

- Developing high-performance Python backend services for LLM inference orchestration, async job handling, streaming responses, and distributed data workflows

- Establishing robust LLMOps and MLOps pipelines on Databricks (AWS) using MLflow, feature stores, prompt evaluation frameworks, model lineage tracking, and continuous retraining workflows

- Applying traditional ML and statistical modeling in hybrid architectures alongside LLMs for interpretable, explainability-first decision systems

- Translating R&D outcomes into scalable, reliable production solutions

- Continuously researching, evaluating, and productionizing advancements in generative modeling, agentic AI, multimodal transformers, and frontier foundation models

The successful candidate will have a Master's or Bachelor's degree in Computer Science, AI/ML, or Engineering, with significant hands-on experience leading and delivering complex Gen AI or ML engineering programs in production environments.

Requirements include:

- Expert-level, hands-on experience designing, building, and deploying LLM applications, agentic systems, and RAG pipelines

- Deep proficiency with LLM ecosystems: OpenAI, Anthropic, Gemini, Hugging Face, and open-source foundation models

- Strong command of Gen AI engineering patterns: prompt engineering, chain-of-thought reasoning, tool/function calling, vector embeddings, semantic search, and agent memory architectures

- Excellent Python engineering skills including async programming, API development, and building inference-ready microservices

- Hands-on experience with cloud AI infrastructure (Databricks, AWS SageMaker, Bedrock, Azure OpenAI, or GCP Vertex AI) and familiarity with MLOps/LLMOps tooling (MLflow, Weights & Biases, etc.)

Benefits and perks are not specified in the job posting.
