Principal Engineer Data Engineering

About This Role The Mission

The data you will build pipelines for is not transactional data or clickstream data. It is experimental measurement data from precision product development instruments each data point costs real time and resources to generate. Getting the data infrastructure right for this kind of scientific data is a genuinely different engineering challenge from standard web-scale or financial data work. You will develop rare expertise in ML-ready scientific data pipelines that very few data engineers in Singapore or globally have built.

Key Responsibilities

• Feature Engineering Pipelines: Build and maintain reliable versioned feature engineering pipelines that transform raw engineering sensor and operational data into structured ML-ready feature sets delivered to the specification defined
• Data Quality Frameworks: Design and operate data quality checks covering completeness schema consistency statistical distribution stability and label accuracy across all AI training datasets. Alert the ML team when data quality degrades before it impacts model training. Collaborate with team who performs final downstream validation.
• Data Versioning Lineage & Drift Detection: Build and maintain training data versioning and lineage tracking ensuring full reproducibility of all model training runs and early alerting when deployment data diverges from training distributions.
• Data Contracts & Governance Guided Implementation: Implement and maintain agreed data contracts between upstream data producers and downstream ML consumers following governance standards established with guidance from ML Engineer. Establish access control and retention practices for all AI data assets.
• Real-Time Streaming Sensor Data Ingestion: Contribute to real-time sensor data ingestion pipelines under technical direction. Develops operational ownership progressively over 612 months. Not a solo day-1 requirement.
• Synthetic Data Pipeline Support: Build pipeline infrastructure to operationalize synthetic data generation workstreams. With generative model methodology provided builds ingestion storage and versioning infrastructure.
• MLOps Data Layer: Build and maintain the training dataset registry feature store and model input validation tightly integrated with the AI platform (AWS Kubernetes PortKey Agent Gateway LangFuse AWS Guardrails Elastic Search etc.).

Qualifications :

Requirements:

Education

• Bachelors or Masters degree in AI Computer Science Data Engineering Electrical Engineering Applied Mathematics or related field. AI major preferred; strong data engineering fundamentals required.

Experience

• Fresh to 1 year. Demonstrated project experience building end-to-end data pipelines academic personal or internship contexts is the primary evaluation criterion. Python SQL and pipeline design fundamentals must be solid and demonstrable through project evidence.

Must Have Skills:

• Python: Strong proficiency primary pipeline development language
• SQL: Strong proficiency complex queries window functions data transformation logic
• Scalable Pipeline Design: Batch pipeline architecture; reliability schema management fault tolerance; Pipeline orchestration (Airflow Prefect AWS Glue Jobs)
• Data Quality Principles: Completeness checks schema validation distribution stability monitoring
• Data Versioning & Lineage: Reproducibility of training data; ability to trace data origin and transformations
• ML Data Lifecycle Awareness: Basic understanding of how data pipelines connect to ML model training. Awareness that data quality and pipeline design affect model performance downstream specifically awareness of risks like train/test data leakage and label quality impact on model accuracy. Does not require prior ML work experience; requires curiosity and conceptual understanding.

Good to have Skills:

• Feature store (Feast Tecton) Synthetic data generation (VAE GAN diffusion models) Data Built Tool (DBT) Data Load Tool DLT   Annotation platform integration (Label Studio CVAT) MES / LIMS system integration Active learning data loop design Data lakehouse (Iceberg Dremio AWS Glue AWS Lake Formation) / Redhsift
