About Supermicro:

Supermicro® is a Top Tier provider of advanced server, storage, and networking solutions for Data Center, Cloud Computing, Enterprise IT, Hadoop/ Big Data, Hyperscale, HPC and IoT/Embedded customers worldwide. We are the #5 fastest growing company among the Silicon Valley Top 50 technology firms. Our unprecedented global expansion has provided us with the opportunity to offer a large number of new positions to the technology community. We seek talented, passionate, and committed engineers, technologists, and business leaders to join us.

Essential Duties and Responsibilities:

1. ETL Pipeline Engineering and Operations (40%)

- Maintain and scale daily ETL/ELT pipelines using workflow or scheduling tools.

- Build extractors for manufacturing reports in multiple formats (Excel, CSV, email attachments, compressed archives).

- Implement incremental loads with idempotent transforms (deduplication, checkpoints, rerun-safe jobs).

- Optimize PostgreSQL batch ingestion (COPY / UPSERT) for large volumes with stable memory use.

- Monitor scheduled production runs; handle failures, alerting, and recovery.

2. Data Services, Analytics, and Reporting (25%)

- Maintain backend data APIs and services that power analytics dashboards and reports.

- Write and tune PostgreSQL queries (CTEs, window functions) for operational and analytical use cases.

- Support dashboard / reporting needs: KPI definition, trend analysis, and ad-hoc data requests.

- Standardize manufacturing metrics such as station yield, First Pass Yield (FPY), and repair turnaround time (TAT).

- Apply basic statistics or data science methods (e.g. anomaly detection, SPC-style quality tracking) where they improve insight.

3. Data Governance and Cross-site Communication (15%)

- Serve as the technical contact for data exchange with contract manufacturing sites.

- Align report formats, column schemas, and naming standards with site engineering teams.

- Improve data quality on incomplete or inconsistent fields (e.g. defect classification, part numbers).

- Manage master data versioning (e.g. BOM) and coordinate automated report collection.

- Investigate source-data issues: template changes, corrupted files, and encoding / formatting errors.

4. Database Administration and Warehousing (20%)

- Design and maintain warehouse layers: staging, ODS, DW, and application summary tables.

- Manage PostgreSQL schema changes, indexing, and routine database maintenance.

- Enforce role-based access control for ETL, BI, and administrative users.

- Maintain data quality checks, pipeline tests, and documentation.

- Own historical backfill procedures: backup, reset, reprocess, and verify.

Qualifications:

Required (Must-Have)

- Python 3: 2+ years hands-on experience; proficient in pandas, numpy, and related libraries for data processing and ETL.

- SQL and relational databases: strong PostgreSQL (or Oracle / MS SQL) skills, including CTEs, window functions, UPSERT, schema design, and indexing.

- Automated data pipelines: experience building and operating production ETL/ELT jobs with workflow or scheduling tools.

- Data quality: schema validation, deduplication, batch processing, and basic error handling / alerting.

- Version control: Git branching workflows and configuration management.

- Communication: able to discuss data requirements with engineering and operations teams in Chinese and English.

- Education: BS/MS in Computer Science, Information Management, Electrical Engineering, Statistics, Mathematics, or a related technical field.

Preferred (Nice-to-Have)

- Web / API backend development (e.g. Python web frameworks) and dashboard / reporting services.

- Data warehousing: staging / ODS / DW layers and aggregate summary tables.

- Analytics: exploratory analysis, KPI definition, and manufacturing or quality metrics (yield, FPY, TAT, SPC).

- Data science fundamentals: statistics, feature preparation, or basic machine learning for reporting and insight.

- Parsing semi-structured files (Excel, CSV, PDF, email attachments, archives).

- Deployment: Windows Server, task scheduling, or Docker.

- Interest in LLM / RAG applications on top of internal data platforms.
