Job Level
About the role
- Develop a strong understanding of Evolv’s sensor ecosystem, datasets, and ML pipelines.
- Review dataset structure, labeling processes, and existing exploratory data analyses.
- Run initial UMAP/PCA/t-SNE analyses to map data distributions and identify anomalies.
- Identify opportunities to improve data quality, labeling consistency, and dataset coverage.
- Perform deep representation analysis across sensor, time‑series, and feature data.
- Evaluate classical ML and deep learning models by linking model errors to data issues.
- Define data quality metrics and initial dataset acceptance criteria.
- Collaborate with data collection teams to guide targeted data acquisition and relabeling.
- Data mining on existing field data and understanding patterns and extract useful information and insights.
- Design methods to improve data quality, converting noisy/unverified data into clean/verified data.
- Own data‑centric insights that directly improve ML model performance.
- Establish ongoing monitoring of data drift, blind spots, and label quality.
- Provide strategic guidance for future data collection, annotation, and curation.
- Develop automated tools and dashboards for data quality reporting and representation analysis.
Requirements
- Master’s or PhD in Data Science, Computer Science, Applied Mathematics, Statistics, Physics, or related field
- 2-3+ years of data science experience working with real‑world ML datasets (time‑series, images, video, sensors)
- Proficiency in Python and data science libraries (NumPy, pandas, matplotlib, seaborn)
- Hands‑on experience using UMAP, t‑SNE, PCA, or other representation analysis methods
- Experience analyzing data for both classical ML and deep learning models
- Strong understanding of ML fundamentals and model evaluation methodologies.
- Experience with sensor or time‑series data (magnetic, radar, 3D, environmental, IoT)
- Familiarity with scikit‑learn workflows and preprocessing techniques.
- Experience addressing imbalanced datasets, label noise, and data drift.
- Knowledge of embedding analysis, feature importance, and model interpretability.
- Experience collaborating with annotation or data collection teams.
- Familiarity with MLOps or data versioning tools (MLflow, W&B, DVC).
