Job Level

About the role

  • Design, develop, and optimize ML models—including XGBoost, Random Forests, SVMs, CNNs, and Transformers.
  • Lead hyperparameter tuning, feature selection, and algorithm evaluation.
  • Integrate models to production system, work with SW team on optimizing runtime speed and performance
  • Develop reproducible training pipelines with model, data, and experiment versioning.
  • Extract temporal, spectral, and domain‑specific features from raw sensor signals.
  • Use data analytics tools such as UMAP and T-SNE to understand data distribution and feature characteristics.
  • Model sensor characteristics such as noise, bias, drift, and environmental effects.
  • Perform ablation studies and feature importance analyses (SHAP, PDP, etc.).
  • Design multi‑class object detection and classification pipelines for noisy, imbalanced datasets.
  • Define evaluation metrics including confusion matrices, calibration, and class‑wise scoring.
  • Deploy production‑ready ML code impacting real customers.
  • Ensure reliability through CI/CD, drift detection, and data validation.
  • Optimize models for edge and compute‑constrained environments.
  • Work with hardware, software, product and cross-functional teams.
  • Communicate technical decisions and trade‑offs to senior stakeholders.

Requirements

  • Master’s or PhD in Computer Science, Machine Learning, Engineering, Applied Math, Physics, or related field.
  • 3- 5+ years building and deploying ML models for real-world applications
  • Strong expertise in classical ML techniques (e.g., XGBoost, Random Forests, SVM, k‑NN) and modern ML techniques (e.g., deep neural network, transformers).
  • Proficiency in Python, ML libraries (scikit‑learn, NumPy, pandas) and C++
  • Experience with multi‑class classification on real‑world, noisy datasets.
  • Strong statistical and model evaluation skills.
Benefits
  • Equity as part of your total compensation package
  • Medical, dental, and vision insurance
  • Health Savings Account (HSA)
  • A 401(k) plan (and 2% company match)
  • Flexible Paid Time Off (PTO)- take the time you need to recharge, with manager approval and business needs in mind
  • Quarterly stipend for perks and benefits that matter most to you
