RADcube is hiring a Senior Data & AI Engineer in Carmel, Indiana (onsite). The role focuses on data modeling, semantic layers, and metadata foundations so AI systems can answer questions accurately, including text-to-SQL and RAG-style workflows, alongside client discovery and stakeholder alignment.
Responsibilities
- Build and maintain data models including dimensional, relational, and lakehouse designs that align with team standards.
- Investigate and document unfamiliar or legacy schemas by producing ER diagrams, data dictionaries, join paths, and lineage.
- Develop and optimize SQL, transformations, and data pipelines on cloud data platforms.
- Convert raw tables into business-facing semantic models covering metrics, dimensions, hierarchies, and relationships.
- Write and enrich schema metadata and descriptions to support improved performance for LLM text-to-SQL and generative BI accuracy.
- Partner with AI engineers on RAG pipelines, agent tools, and prompt design when the system relies on structured data.
- Test and evaluate AI-generated queries for correctness, including contributions to test sets and guardrails.
- Participate in client discovery to understand business processes, KPIs, and reporting requirements.
- Translate business questions into data requirements and validate metric definitions with stakeholders.
- Communicate data findings clearly to both technical and non-technical audiences.
- Apply data quality checks, naming standards, and documentation practices.
- Follow relevant governance and compliance requirements (GxP, HIPAA) where applicable.
- Review peers’ work and support junior engineers when needed.
Requirements
- 6+ years of experience in data engineering, analytics engineering, or BI development.
- Strong SQL skills and a solid understanding of relational and dimensional modeling.
- Proven ability to learn and navigate large enterprise schemas (for example, 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, including text-to-SQL, semantic layers, or AI-assisted analytics.
- Good business sense and comfort discussing KPIs and processes with stakeholders.
