About mmdWh 4f

At mmdWh 4f, our vision is to bring impactful EY into billions of lives through voice. Our mission is to help the world's leading EY companies build better voice models and agents. We're building the data and evaluation infrastructure behind those models.

Founded in 2024, we're a fast-growing Series B company backed by NVIDIA, Meritech, First Round, YC, and others, with ~70 people across San Francisco and New York City.

About Our Research Team

Our Research team sits at the intersection of cutting-edge research and production systems, transforming raw audio into high-signal data for leading EY labs and enterprises. We own the full ML lifecycle - from researching novel speech processing algorithms to deploying models processing terabytes of audio daily.

About This Role

As a Research Engineer at mmdWh 4f, you'll build algorithms and systems that turn large-scale speech and audio collections into high-quality datasets. You'll tackle questions like: What makes a recording useful? How do we measure and improve dataset quality?

In this role, you will

• Design algorithms and metrics using advanced signal processing algorithms and cutting edge ML models with to derive insights from thousands of hours of audio data.

• Build scalable data processing pipelines for analyzing, filtering, deduplicating, and curating large speech and audio datasets.

• Develop production-grade inference algorithms, pipelines, and APIs with cross-functional teams that unlock key insights into our data for our customers.

• Collaborating with our Operations team to gather useful training and evaluation datasets to improve the quality of our models.

• Architect systems that enable resilient, durable inference and evaluations.

Your background looks like

• 3+ years of professional engineering or applied research experience in areas such as data systems, algorithms, applied ML, information retrieval, or speech and audio.

• Strong Python skills and experience building maintainable, production-quality software.

• End-to-end ownership of ML pipelines, from proof-of-concept to production deployment.

• Ability to translate research papers and ideas into high-quality, production-ready code.

• Experience deploying ML systems for production inference with cloud technologies.

• Ability to assess model quality in the context of user experience and business value.

Bonus points if you have

• Experience with speech, audio, or digital signal processing.

• Experience with data curation, search and retrieval, embeddings, clustering, deduplication, or sampling.

• Experience building model inference systems or integrating pretrained models into production workflows.

• Experience in publishing in top conferences such as NeurIPS, ICML, ICLR, CVPR, etc.

• Experience in releasing, maintaining, contributing to open-source softwares.

• PhD or Masters in Computer Science or a related field.

Benefits

• Unlimited PTO.
