Machine Learning Engineer — Multilingual Data

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.

What You’ll Do

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

What We’re Looking For

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

Nice to Have

Experience with low-resource languages or multilingual benchmarks (e.g. FLORES, XTREME)

Exposure to LLM training, fine-tuning, or distillation

Linguistics background or experience working with native language experts

Contributions to open-source datasets or ML tooling

Experience with data quality evaluation at scale

Why Join

Real ownership over a core differentiator of the product

Work on models used globally, not just in English-speaking markets

Small, high-caliber team with deep ML and systems experience

Competitive compensation + meaningful equity at Series A stage
