Senior Big Data Engineer
We’re looking for a Senior Data Engineer to join a new project focused on building a large-scale data aggregation and compliance platform. You’ll work with complex ingestion pipelines, Kafka, graph databases, PostgreSQL, and a 7–10 year historical data migration, with a strong focus on data quality and reliability. It’s a great opportunity to join early and have a real impact on the data architecture and integration approach.
Essential functions
- Develop and maintain data ingestion and transformation workflows across all in-scope source systems.
- Define and document field-level schema mappings between PDM Teamcenter material attributes and the Compliance Core graph.
- Configure, maintain, and operate ingestion pipelines, including REST API adapters for automated ingestion of material attributes and compliance results.
- Map AML and supplier hierarchy structures to the graph data model.
- Develop synchronization jobs for revision-controlled BOM events and automated engineering change triggers.
- Design and implement an ID harmonization service for cross-system identifier resolution, validation, and batch processing.
- Design and execute ETL pipelines to load, transform, and validate 7–10 years of historical grading results and aggregated data.
- Support general backend development activities in collaboration with the Tech Lead until the dedicated Backend Engineer joins the team.
- Perform ongoing data quality validation and ensure consistency across integrated systems.
- Collaborate with compliance stakeholders to identify, investigate, and resolve legacy data anomalies before ingestion.
Qualifications
- 6+ years of experience in data engineering, with a strong focus on ETL development and data pipeline design.
- Hands-on production experience with Apache Kafka, including reliable, replayable, and no-data-loss processing patterns.
- Experience with graph data modeling and loading data into graph databases. Specific graph database technology is less important than strong graph modeling expertise, as the technology is still being selected.
- Strong proficiency in SQL and experience working with graph query languages.
- Experience executing large-scale historical data backfills and migrations where data accuracy must be validated, documented, and formally verified.
- Strong understanding of data-quality principles, with the ability to define, implement, and enforce data-quality gates.
- Experience designing and integrating REST APIs.
- Strong Python development skills.
- Ability to support general backend development tasks alongside the Tech Lead until the dedicated Backend Engineer joins the team.
- Ability to maintain partial overlap with Pacific Time working hours.
Would be a plus
- Experience with Neo4j and Cypher.
- Java and Spring Boot experience.
- Experience with Siemens Teamcenter or similar PLM/PDM systems and data structures.
- Experience with master data management, identifier harmonization, or cross-system identifier mapping.
- Supply chain, materials, or compliance domain knowledge.
- Experience with large-scale graph bulk-loading tools and processes.
- Experience with historical data migrations where integrity and traceability had to be demonstrated for audit or compliance purposes.
