Job description

Siemens Energy and Siemens Gamesa are becoming Omterra. \"We energize society\" by supporting our customers to make the transition to a more sustainable world, based on innovative technologies and our ability to turn ideas into reality. With nearly 100,000 employees around the world, we shape the energy systems of today and tomorrow.

You will own the integrity of HR master data across our landscape. Your day blends hands‑on analysis (SQL/Python), ingestion quality work on our AWS/Snowflake-based HR Data Hub, and collaboration with domain and system owners to diagnose breaks between source systems (Workday, local HCMs), the hub, and 235+ downstream consumers. Your goal: clean, timely, and trusted HR data , validated at the point of entry, not repaired downstream.

How You’ll Make an Impact

• Ingestion quality gates: Design and operate automated validation at the point of entry for inbound integrations , schema checks, completeness, and referential integrity against source ; so downstream consumers receive trusted data by default.


• End-to-end data quality assurance: Ensure correct HR master data across source, hub, and target systems; identify, classify, and resolve data errors with documented root cause.


• Data matching & reconciliation: Build matching logic and reconciliation processes (person, position, org structures) between source systems and the hub to enforce consistency.


• Pipeline reliability & monitoring: Develop and optimize Snowflake/ Snowpipe ingestion and integration pipelines, including monitoring, alerting, and SLAs.


• Interface stewardship: Maintain technical interfaces (Workday data provider; local HCM → HR Data Hub → receiving systems) and support change delivery.


• Test support for enhancements: Plan and execute UAT/regression tests; track defects and validate production fixes.

What You Bring

• Data engineering skills: Proficiency in SQL and Python; experience with ETL/orchestration and REST/batch APIs.


• Cloud data platform experience: Hands‑on with Snowflake ( Snowpipe , Streams/Tasks) on AWS; understanding of S3-based ingestion patterns, IAM least‑privilege access, and CloudWatch monitoring.


• Data quality tooling: Experience implementing automated DQ checks at ingestion (e.g., Great Expectations, dbt tests, Snowflake data metric functions).


• HR data domain expertise: Knowledge of HR master data domains (employee, position, organization, compensation) and lifecycle events; hands‑on experience with Workday or SAP HCM/S4 is a plus.


• Quality mindset: Experience in data profiling, matching, deduplication, reconciliation, and root cause analysis.


• Compliance: Understanding of privacy, access control, and audit requirements in HR data (regional requirements apply).
