About the Role

RADcube is hiring a hands-on Senior Engineer who knows data, AI, and the business. You will dig into complex enterprise schemas, work out what the data means to the business, and build the models, semantic layers, and metadata that let AI systems answer questions accurately. You will contribute directly to our RADLabs accelerators, including generative BI and agentic platforms, and to client work in pharma, life sciences, and healthcare.

What You'll Do

Schema & Data Modeling

• Build and maintain data models (dimensional, relational, lakehouse) that follow team standards.
• Explore and document unfamiliar or legacy schemas, producing ER diagrams, data dictionaries, join paths, and lineage.
• Develop and optimize SQL, transformations, and pipelines on cloud data platforms.

Semantic Layer & AI Enablement

• Translate raw tables into business-friendly semantic models: metrics, dimensions, hierarchies, and relationships.
• Write and enrich schema metadata and descriptions to improve LLM text-to-SQL and generative BI accuracy.
• Work with AI engineers on RAG pipelines, agent tools, and prompt design where structured data is involved.
• Test and evaluate AI-generated queries for correctness, and help build test sets and guardrails.

Business Understanding

• Take part in client discovery sessions to understand processes, KPIs, and reporting needs.
• Turn business questions into data requirements and validate metric definitions with stakeholders.
• Explain data findings clearly to both technical and non-technical audiences.

Quality & Collaboration

• Apply data quality checks, naming standards, and documentation practices.
• Follow governance and compliance requirements (GxP, HIPAA) where relevant.
• Review peers' work and support junior engineers when needed.

Requirements

What You Bring

Must-Have

• 6+ years in data engineering, analytics engineering, or BI development.
• Strong SQL and solid understanding of relational and dimensional modeling.
• Demonstrated ability to learn and navigate large enterprise schemas (SAP, Salesforce, MES, or similar).
• Hands-on experience with AWS (Redshift, Glue, Athena, S3) and/or Azure (Synapse, Fabric, Data Factory), plus Databricks or Snowflake.
• Proficiency in Python for data work.
• Practical exposure to LLMs on structured data, such as text-to-SQL, semantic layers, or AI-assisted analytics.
• Good business sense and comfort talking with stakeholders about KPIs and processes.

Nice-to-Have

• Experience in pharma, life sciences, manufacturing and quality, or healthcare data.
• dbt, or semantic layer tools such as Cube, dbt Semantic Layer, or LookML.
• Familiarity with vector databases, knowledge graphs, or agentic frameworks (LangChain/LangGraph, Bedrock Agents, MCP).
• Data catalog tools such as Unity Catalog, Collibra, or AWS DataZone.
• AWS, Azure, or Databricks certifications.

What Success Looks Like (First 6 Months)

• Semantic models and metadata are delivered for at least one accelerator or client use case.
• AI-generated query accuracy measurably improves on the datasets you own.
• Schema documentation is good enough that others on the team can pick it up and run with it.
• Stakeholders trust you to understand both their data and their business.
