Build pipelines for data ingestion, feature engineering, model training, evaluation, and deployment

Work on productionizing models: monitoring, scalability, latency, retraining, A/B testing, and model lifecycle management

Develop infrastructure and tooling to support ML experimentation and production (e.g., model serving, MLOps, observability)

Collaborate with cross-functional partners (product managers, software engineers, UX researchers) to integrate ML features into product flows

Keep abreast of latest ML/AI research, propose novel approaches, publish (internally or externally) when appropriate

Required

A Master's or PhD in Computer Science, Machine Learning, Statistics, Applied Math or equivalent experience

Solid understanding of ML fundamentals: supervised & unsupervised learning, deep learning, model evaluation metrics, deployment, inference latency trade-offs

Familiarity with knowledge representation and retrieval: building or leveraging knowledge graphs, embeddings, and memory systems to support contextual inference and long-term model learning

5+ years of hands-on experience building machine learning models in production environments – we ship features fast, so we need someone who can keep up

Experience deploying models at scale in production (AWS/GCP/Azure)

Experience with data engineering (ETL pipelines, feature stores, large datasets) and production-grade MLOps (CI/CD, monitoring, retraining workflows)

Ownership mentality (no task is too small for you) – it's all hands on deck here and we need everyone rowing the boat

Deep understanding of system architecture and design patterns – we're looking for someone who can hit the ground running day one

Excellent communication skills and a collaborative mindset – we're extremely lean so we're looking for a team player who works well with others

Type-A tendencies: maybe you're extremely detail-oriented. Or maybe you take pride in shipping high-quality products. Whatever it is you do, you give it your all

Must be based in or willing to relocate to NYC – although we're flexible with days off & schedules, we have a 100% in-office culture during the week
