About

Big Data Engineer
AdvanSix plays a critical role in global supply chains, innovating and delivering essential products for our customers in a wide variety of end markets and applications that touch people's lives. Our reliable and sustainable supply of quality products emerges from the vertically integrated value chain of our three U.S. based manufacturing facilities. AdvanSix strives to deliver best-in-class customer experiences and differentiated products in the industries of nylon solutions, chemical intermediates, and plant nutrients, guided by our core values of Safety, Integrity, Accountability and Respect. AdvanSix is seeking a Big Data Engineer to build and operate our enterprise Unified Data Layer (UDL) - spanning IT and OT - to deliver trustworthy, performant data products that power Finance, Operations, Supply Chain & Logistics, HSE, Commercial, and corporate analytics. 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. 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. 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. 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. 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. 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. Minimum 5 years' 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. 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 401K 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. At AdvanSix, we are dedicated to building a diverse, inclusive, and authentic workplace, so if you're excited about this role but your past work experience doesn't perfectly align with every qualification in the job posting, we encourage you to still apply. You may just be the right candidate for this or other roles. AdvanSix is an equal opportunity employer. Qualified applicants will be considered without regard to age, race, creed, color, national origin, ancestry, marital status, affectional or sexual orientation, gender identity or expression, disability, nationality, sex, religion, veteran status, or any other protected classification.
