We’re looking for a Machine Learning Engineer to own and scale our multilingual data pipeline—from sourcing and curation to evaluation and continuous improvement. You’ll work closely with researchers and infra engineers to ensure our models perform robustly across languages, scripts, and cultural contexts.

This role sits at the intersection of data, research, and production ML and is ideal for someone who cares deeply about data quality, linguistic diversity, and model generalization beyond English.

Responsibilities

→
Design, build, and maintain large-scale multilingual datasets across high- and low-resource languages
→
Develop data pipelines for collection, cleaning, normalization, deduplication, and labeling
→
Implement quality filters using statistical, heuristic, and model-based methods
→
Work with researchers to define language coverage, benchmarks, and evaluation metrics
→
Analyze dataset bias, coverage gaps, and failure modes across regions and scripts
→
Support training, fine-tuning, and distillation workflows with high-quality multilingual data
→
Continuously iterate on datasets based on model performance and real-world usage

3+ years of experience as an ML Engineer, Applied Scientist, or similar role
Strong experience working with multilingual or non-English datasets
Solid understanding of NLP fundamentals (tokenization, embeddings, language modeling)
Experience building scalable data pipelines (Python, Spark, Ray, or similar)
Familiarity with Unicode, scripts, tokenization challenges, and language-specific quirks
Comfort collaborating with researchers and translating research needs into production systems
