Data Engineer / Data Architect III

The Lead Data Engineer / Data Architect will spearhead the creation of our next-generation “Analytics Core” within a closed, classified, on-premises environment. This mission-critical project will unify our 30-year legacy archive of diverse data—including reports, sensor data, imagery, and heavily geospatial intelligence—into a single, query-able, and AI-ready ecosystem.Because our historical data is highly complex with deep attribution challenges, this is a “roll-up-your-sleeves” role. We expect a balance of approximately 60% hands-on data engineering (ETL pipeline construction, data cleaning, and mapping) and 40% data architecture (strategic design and governance).As our management team upskills our dedicated in-house staff to execute the broader data migration, this role will act as the technical anchor. The Lead Data Engineer / Data Architect will build strong relationships, set clear technical standards, and seamlessly interface with transitioning staff to ensure the project’s success.Oceaneering is a global provider of engineered services and products, primarily to the offshore energy industry.
