Job Title: Data Scientist - Signal Modeling & Applied Metrology
Location: On-Site (San Leandro, CA)
Job Type: Full-Time
Role OverviewWe are seeking a
Data Scientist to join our Applications Engineering team. In this role, you will build and deploy machine learning models that turn complex, high-dimensional sensor signals into actionable predictions about material properties, bridging the gap between raw instrument data and manufacturing intelligence.
This is a forward-deployed, customer-adjacent role. You will work directly with customer samples and datasets to execute proof-of-concept studies, validate model performance on novel materials, and translate results into product improvements. You will collaborate closely with software and hardware engineering teams to move models from research into production.
What You'll DoModel Development & Calibration- Build, calibrate, and validate predictive models that map sensor signal features to material properties
- Design and evaluate new model architectures and featurization strategies suited to small-data, high-dimensional scientific datasets
- Apply methods including regression, dimensionality reduction, probabilistic modeling, anomaly detection, and physics-informed ML
Model Validation & Production Readiness- Develop testing and validation frameworks for model performance, including uncertainty quantification and out-of-distribution detection
- Characterize model robustness across sample types, process conditions, and instrument configurations
- Prepare models and documentation for handoff to the software engineering team for production deployment
Customer-Facing Proof-of-Concept Work- Analyze datasets from customer proof of concepts
- Compile technical reports and supporting materials to deliver to customers
- Translate findings and stakeholder feedback into model improvement roadmaps
What We're Looking For- B.S. in Data Science, Statistics, Applied Mathematics, or a related quantitative science field with 3-5 years of applied ML/data science experience; or M.S. with 1-3 years (Ph.D. a plus, not required)
- Hands-on experience building and validating predictive models (supervised and self-supervised) in Python
- Ability to analyze multivariate, high-dimensional datasets and perform feature engineering and selection
- Solid grasp of statistical modeling: uncertainty quantification, regularization, covariate analysis, and feature importance methods
- Strong communicator; comfortable presenting technical findings to both technical and non-technical audiences
Nice to have:- Experience working with time-series, spectroscopic, or other sensor-based signal data
- Prior work in manufacturing, materials science, energy storage, semiconductors, or another physical science domain
- Prior customer-facing or applications engineering experience in a technical product company
- Experience deploying models in production software environments
- Familiarity with data pipeline development (PostgreSQL or similar)
- Fluency in Mandarin Chinese, Japanese, German, Korean, or another key stakeholder language
Base Pay Range
$100,000-$160,000 USD
Benefits- Equity and Salary compensation depends on experience
- Health, Dental, Vision plans provided
- 401k matching provided
- Time off: 20 days of PTO per year, plus approximately 15 paid US holidays per year
