About the Role：
We are seeking a Data Infrastructure Engineer to join our growing team. In this role, you will design, build, and operate distributed data systems that power large-scale ingestion, processing, and transformation of datasets used for AI model training. These datasets span traditional structured data as well as unstructured assets such as images and 3D models, which often require specialized preprocessing for pretraining and fine-tuning workflows.
This is a versatile role: you’ll own end-to-end pipelines (from ingestion to transformation), ensure data quality and scalability, and collaborate closely with ML researchers to prepare diverse datasets for cutting-edge model training. You’ll thrive in our fast-paced startup environment, where problem-solving, adaptability, and wearing multiple hats are the norm.
What You’ll Do：
- Core Data Pipelines
- Design, implement, and maintain distributed ingestion pipelines for structured and unstructured data (images, 3D/2D assets, binaries).
- Build scalable ETL/ELT workflows to transform, validate, and enrich datasets for AI/ML model training and analytics.
- Pretrain Data Processing
- Support preprocessing of unstructured assets (e.g., images, 3D/2D models, video) for training pipelines, including format conversion, normalization, augmentation, and metadata extraction.
- Implement validation and quality checks to ensure datasets meet ML training requirements.
- Collaborate with ML researchers to quickly adapt pipelines to evolving pretraining and evaluation needs.
- Distributed Systems & Storage
- Architect pipelines across cloud object storage (S3, GCS, Azure Blob), data lakes, and metadata catalogs.
- Optimize large-scale processing with distributed frameworks (Spark, Dask, Ray, Flink, or equivalents).
- Implement partitioning, sharding, caching strategies, and observability (monitoring, logging, alerting) for reliable pipelines.
- Infrastructure & DevOps
- Use infrastructure-as-code (Terraform, Kubernetes, etc.) to manage scalable and reproducible environments.
- Integrate CI/CD best practices for data workflows.
- Data Governance & Collaboration
- Maintain data lineage, reproducibility, and governance for datasets used in AI/ML pipelines.
- Work cross-functionally with ML researchers, graphics/vision engineers, and platform teams.
- Embrace versatility: switch between infrastructure-level challenges and asset/data-level problem solving.
- Contribute to a culture of fast iteration, pragmatic trade-offs, and collaborative ownership.
What We’re Looking For：
- Technical Background
- 5+ years of experience in data engineering, distributed systems, or similar.
- Strong programming skills in Python (plus Scala/Java/C++ a plus).
- Solid skills in SQL for analytics, transformations, and warehouse/lakehouse integration.
- Proficiency with distributed frameworks (Spark, Dask, Ray, Flink).
- Familiarity with cloud platforms (AWS/GCP/Azure) and storage systems (S3, Parquet, Delta Lake, etc.).
- Experience with workflow orchestration tools (Airflow, Prefect, Dagster).
- Domain Skills (Preferred)
- Experience handling large-scale unstructured datasets (images, video, binaries, or 3D/2D assets).
- Familiarity with AI/ML training data pipelines, including dataset versioning, augmentation, and sharding.
- Exposure to computer graphics or 3D/2D data processing is strongly preferred.
- Mindset
- Comfortable in a startup environment: versatile, self-directed, pragmatic, and adaptive.
- Strong problem solver who enjoys tackling ambiguous challenges.
- Commitment to building robust, maintainable, and observable systems.
Nice to Have：
- Kubernetes for distributed workloads and orchestration.
- Data warehouses or lakehouse platforms (Snowflake, BigQuery, Databricks, Redshift).
- Familiarty GPU-accelerated computing and HPC clusters
- Experience with 3D/2D asset processing (geometry transformations, rendering pipelines, texture handling).
- Rendering engines (Blender, Unity, Unreal) for synthetic data generation.
- Open-source contributions in ML infrastructure, distributed systems, or data platforms.
- Familiarity with secure data handling and compliance
Our Values：
- Brain: We value intelligence and the pursuit of knowledge. Our team is composed of some of the brightest minds in the industry.
- Heart: We care deeply about our work, our users, and each other. Empathy and passion drive us forward.
- Gut: We trust our instincts and are not afraid to take bold risks. Innovation requires courage.
- Taste: We have a keen eye for quality and aesthetics. Our products are not just functional but also beautiful.
- Competitive salary, equity, and benefits package.
- Opportunity to work with a talented and passionate team at the forefront of AI and 3D technology.
- Flexible work environment, with options for remote and on-site work.
- Opportunities for fast professional growth and development.
- An inclusive culture that values creativity, innovation, and collaboration.
- Unlimited, flexible time off.
Benefits：
- Competitive salary, benefits and stock options.
- 401(k) plan for employees.
- Comprehensive health, dental, and vision insurance.
- The latest and best office equipment.
