Senior Full Stack Engineer

Accountabilities • Design, orchestrate, and deploy robust multi-agent systems using LangGraph and LangChain to support complex pharmaceutical workflows, including literature synthesis, adverse event extraction, clinical trial protocol drafting, and code or data validation.

• Build and benchmark enterprise RAG pipelines using hybrid semantic search, domain-specific embeddings such as BioBERT and PubMedBERT, reranking techniques, and optimized chunking strategies across AWS OpenSearch and vector databases.

• Integrate foundation models, including Claude, Llama, and specialized fine-tuned biomedical language models, through AWS Bedrock. Implement Bedrock Agents or AgentCore and custom Action Groups for structured downstream execution.

• Develop agent governance and safety mechanisms, including deterministic guardrails, citation attribution, hallucination detection, human-in-the-loop checkpoints, and audit trails to support clinical reproducibility.

• Build production-grade asynchronous RESTful and streaming APIs using Python and FastAPI, managing application state, background workers, and distributed processes with tools such as Celery, Redis, and SQS.

• Develop responsive web applications using React.js and TypeScript, including clinical dashboards, streaming chat interfaces, graph visualizations, and validation workflows.

• Design and maintain high-performance relational and non-relational data architectures using PostgreSQL, PGVector, DynamoDB, DocumentDB, and MongoDB.

• Architect containerized cloud solutions using Docker, AWS ECS with Fargate, or Kubernetes, alongside serverless services such as Lambda, Step Functions, EventBridge, and S3.

• Implement data protection and security controls for sensitive personal and health information, supporting compliance with HIPAA, GDPR, GxP, and 21 CFR Part 11.

• Establish auditability and software quality practices through immutable audit logs, SOUP scanning, anti-malware workflows, SonarQube quality gates, and automated testing with pytest and Playwright or Selenium.

Requirements:

• At least 6 years of full-stack software development experience, including a minimum of 2 years building and deploying generative AI and agentic workflows in production.

• Expert-level proficiency in Python 3.x, FastAPI, asynchronous programming, and enterprise API design patterns.

• Strong hands-on experience with React.js, modern state management tools such as Redux Toolkit or Zustand, and real-time communication technologies including WebSockets and Server-Sent Events (SSE).

• Experience with scientific data visualization libraries and building interfaces for complex technical or clinical workflows.

• Proven experience deploying production agentic AI workflows using LangGraph and LangChain, including state graphs, cyclical workflows, reflection, multi-agent collaboration, and handoffs.

• Deep understanding of tool calling, function calling, dynamic routing, and the Model Context Protocol (MCP).

• Hands-on expertise in enterprise RAG systems, including query rewriting, self-correction, and hybrid search.

• Strong practical experience with AWS services, particularly Bedrock, OpenSearch, ECS, Lambda, S3, IAM, CloudWatch, and EventBridge.

• Solid DevOps and testing capabilities, including Docker, GitLab CI/CD or GitHub Actions, static security analysis, unit testing with pytest, and integration testing.

• Preferred: Experience in pharmaceutical, biotech, clinical trials, pharmacovigilance, or medical imaging environments.

• Preferred: Familiarity with DICOM standards, AWS HealthImaging, and clinical data formats such as CDISC, FHIR, or HL7.

• Preferred: Experience configuring AWS Bedrock Agents or AgentCore, including OpenAPI schemas.

• Preferred: Knowledge of hosting and experimenting with specialized open-weight models such as BioMistral, Med-PaLM, Ollama, or Hugging Face models using AWS SageMaker.

• Preferred: AWS Certified Solutions Architect (Associate or Professional) or AWS Machine Learning Specialty certification.
