Senior AI Application Engineer

At Bristol Myers Squibb, our employees often ask, “Who are you working for?”—a question that fuels collaboration, accountability, and urgency in our work. Our purpose-driven culture inspires us to discover, develop, and deliver innovative medicines to prevail over serious diseases. We offer uniquely interesting and meaningful work, opportunities for growth, and a supportive environment that values inclusion, wellbeing, flexibility, and comprehensive benefits. This is work that transforms the lives of patients, and the careers of those who do it.

As a Senior Application Engineer within Bristol Myers Squibb's AI Venture Studio delivery team, you will be a hands-on senior individual contributor responsible for building secure cloud-hosted applications including, but not limited to, agentic AI products and cross functional knowledge and context infrastructure. You will design APIs, services, infrastructure patterns, deployment pipelines, semantic-layer evolution patterns for agent context engineering, and agent runtimes that allow AI Accelerator pods to move quickly without giving up reliability, observability, security, or enterprise alignment. The role is deeply tied to the AI Accelerator delivery model: six two-week sprints over a 12-week cycle to build, test, validate, and prepare MVPs for scaling in a fully agile model. You will leverage the latest technologies to address pharma-specific unsolved problems across R&D, Commercialization, Manufacturing, and Enabling Functions, where critical context is buried in unstructured knowledge files, multimodal documents and reports, operational records, scientific evidence packages, and other evolving knowledge sources. BMS is an AWS-first engineering environment for these products, so you will default to AWS-native services and patterns while integrating BMS-preferred AI tools such as LangGraph, FastMCP, OpenSearch, Amazon S3 Vectors, Amazon Neptune, PostgreSQL/RDS, Redis, AWS Fargate, LangSmith, and a variety of approved frontier LLM models and APIs. This is a role for someone excited to work hands-on with the latest AI tools and frontier technologies, pushing the limits of what technology can do to help BMS discover, develop, and deliver innovative medicines.

Cloud-Native Application and API Engineering: Design, build, and operate backend services, APIs, and application components that power AI Accelerator products. Develop Python/FastAPI, TypeScript/Node, or similar services that integrate LLM APIs, retrieval systems, workflow engines, and internal enterprise systems. Execute AI Accelerator cycles of six two-week sprints over a 12-week cycle by developing, testing, and validating cloud and agentic AI product increments. Develop MCP-accessible services that allow approved agents to read, write, search, and maintain structured (e.g. markdown/YAML) knowledge assets. Build MCP/FastMCP read-write-search APIs, permissioned knowledge stores, version control, audit trails, access controls, and integrations with AWS-native storage and identity patterns. Implement secure application patterns for authn/authz, BMS SSO, BMS Cloud Creds, secrets management, auditability, input validation, and safe service boundaries. Partner with frontend engineers to define clean API contracts, streaming response patterns, error handling, and service-level behaviors for AI-powered user experiences. Agent Runtime, Retrieval, and AWS Platform Patterns: Build and host agentic workflows using LangGraph, including workflow state, multi-agent orchestration, tool execution, fan-out/fan-in patterns, and durable checkpoints. Develop MCP tool integrations and FastMCP servers that allow agents to use governed enterprise capabilities safely and consistently. Implement retrieval, memory, and context services using AWS-aligned data stores such as S3, Athena, PostgreSQL/RDS, ElastiCache/Redis, OpenSearch, Amazon S3 Vectors, and Amazon Neptune. Build and evolve the semantic layer for SQL
