You’ll engineer batch/CDC/streaming pipelines, model curated/semantic layers, and harden run‑state with testing, CI/CD, security, and observability. You’ll partner closely with the data team and larger IT organization. Mission Design and deliver scalable, secure data pipelines and data models that safely connect operational systems to analytics, ensure trusted and well‑governed data, and enable repeatable delivery of BI, ML, AI, and automation solutions. Data Pipeline Development Build ingestion pipelines (batch, CDC, streaming) from S/4HANA/DataSphere, PHD/historian, LIMS, TMS, HSE, and other sources into landing → curated → semantic layers. Implement data contracts, schema/versioning, SCD handling, partitioning, and performance tuning (file formats, clustering, caching). Develop dimensional/semantic models that back certified Power BI datasets and APIs for apps/agents. OT/IT Integration & Safety Integrate OT data via OPC UA/MQTT, broker/DMZ patterns, read-only historian feeds, and event/batch frames—no control‑net reads. Collaborate with plant controls on change control, signal quality, and downtime windows. Quality, Security & Observability Embed data quality rules, unit/integration tests, and validation checks (freshness, completeness, drift/PSI). Instrument lineage and end-to-end monitoring; build alerting and on‑call runbooks to minimize MTTR. Enforce RBAC, secrets management, PII/HSE classifications, and retention aligned to Governance/MDM policies. CI/CD, Cost & Reliability Automate build/test/deploy with Git‑based CI/CD (environments, approvals, blue/green). Track and optimize cost/performance (cluster sizing, autoscaling, cache strategy); contribute to FinOps reviews. Partner with Reporting & BI on semantic model contracts, RLS, and performance SLAs; avoid direct system scraping. Produce “readme” docs, data dictionaries, runbooks, and post‑incident reviews; support knowledge transfer with vendors. Basic Qualifications Minimum 5 years’ experience in data engineering building production pipelines at scale (batch, CDC, streaming). Hands‑on with Azure data stack: Databricks or Fabric/Synapse, ADF/Pipelines, ADLS/OneLake, Azure SQL/SQL MI, Key Vault. Strong SQL and Python/PySpark; comfort with Spark Structured Streaming and performance tuning. Experience implementing tests/observability (freshness, schema, expectations), and Git‑based CI/CD. Familiarity with SAP S/4HANA structures and SAP DataSphere semantic modeling. OT concepts: historians (PHD/PI), OPC UA/MQTT, event/batch frames, ISA‑95/99 basics. Understanding of Power BI consumption (semantic models, RLS) and APIs for downstream AI/ML apps/agents. Preferred Qualifications Time‑series/data‑quality tooling (e.g., Great Expectations or equivalent patterns), feature/metric stores. MDM concepts (keys, survivorship), lineage/catalog tooling. TMS/WMS, LIMS, Historian, HSE domain exposure; Lean/Six Sigma mindset; FinOps awareness. Compensation and Benefits The base salary range for this position is $104,600 to $156,800 annually. We offer a range of market‑competitive total rewards that include periodic pay rate adjustments based on market competitiveness. Hired applicants will be eligible for paid holidays, paid time off including vacation, eligibility to purchase company stock, tuition reimbursement, and a 401(k) with a competitive company match. Certain roles may be eligible for discretionary financial benefits such as incentive pay, equity awards, and participation in a deferred compensation plan. Hired applicants will be eligible for medical, dental and vision insurance, flexible spending and health savings account eligibility, employer‑provided short‑term disability benefits, eligibility to purchase long‑term disability benefits, employer‑provided basic life insurance and eligibility to purchase voluntary life coverages. The pay range, incentives and benefits listed above are general guidelines only and not a guarantee of total compensation or benefits. The final offer will depend on multiple factors, including but not limited to the responsibilities of the job, experience, education, knowledge, skills, and abilities, as well as the job location, applicability of a collective bargaining agreement, length of service, internal equity, and alignment with market data. The incentive pay is dependent on your role, business results and individual performance. All aspects of total rewards offered are subject to the terms and conditions of the specific plans.
