Role description

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.

Responsibilities

  • 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.

  • Hands-on production experience with Apache Kafka, including reliable, replayable, and no-data-loss processing patterns.

  • 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.

Nice to have

  • 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.

We offer

  • Opportunity to work on bleeding-edge projects

  • Competitive salary
  • Flexible schedule
  • Benefits package - medical insurance, sports
