This foundation will support generative AI applications, including retrieval-augmented generation (RAG), and enable analysis of diverse data sets. Looking for an engineer with strong architectural and hands-on development skills who can define the foundation (tools, schemas, and ontologies) and document that definition so that software engineers can implement, and management can understand the capabilities that the foundation can support.

This role is open to candidates across a range of experience levels. The scope of the position and corresponding compensation will be aligned with the selected candidate’s background and expertise.

Primary Responsibilities

Design and implementation of big data systems, ETL pipelines and Data Lakes / Lakehouse / Meshes.
Design and implementation of schema and ontologies.

Design and implementation of row/cell level data access control.
Hands-on software development using Python and/or JavaScript to support data integration and application functionality.
Documentation of data definitions and designs.

Basic Qualifications

Bachelor’s degree with 8+ or 12+ years of experience in a Science, Engineering, or Technology field, or a Master’s degree with 6+ or 10+ years of experience in a Science, Engineering, or Technology field. Additional experience may be considered in lieu of a degree.
U.S. citizenship; ability to obtain a Top Secret security clearance in DISS.
5+ years of experience designing and developing systems to analyze structured and unstructured large data sets from disparate sources, including Extract, Transform, Load (ETL) processes.
5+ years of experience with principles associated with AI applications, including retrieval-augmented generation (RAG), prompt and context engineering, and AI workflow orchestration and design.
Experience with AI agent configuration, management, and integration into automated workflows.
Ability to develop tools, algorithms, and queries to improve business performance.
Ability to develop new technical solutions, including hands-on Python or JavaScript development and Python-based services, to achieve project goals.
Ability to develop intelligent systems that analyze data, learn from patterns, predict outcomes, and make informed decisions autonomously.
Strong verbal and written communication skills, with the ability to communicate data engineering and architectural concepts to non-technical audiences.
Experience working directly with product owners, including previous experience in product ownership or product architecture.

Preferred Qualifications

Experience integrating and/or operating: Dagster, PostgresSQL, Alembic, pgvector
Experience with digital Engineering (SysML).
Experience with generative AI applications, including RAG, embeddings, and vector search.
Experience with operational support to data foundation and devOps.
