Senior AI/Machine Learning Engineer
About The Position
Join Evolv as Senior AI/Machine Learning Engineer to advance AI innovation in physical security technology. As a key team member of the AI/ML team, you will be developing and deploying state-of-the-art machine learning and deep learning solutions. Your role will involve leveraging diverse data sources, including magnetic sensors, 3D cameras and other sensors, to create multi-sensor fusion solutions that operate in real-time on constrained hardware platforms. This hands-on role requires deep expertise in classical ML, deep learning, feature engineering, model optimization, and MLOps. You will drive modeling strategy, strengthen model accuracy and robustness, and deploy reliable models in real-world environments. This position is ideal for someone known for measurably improving models—not just building them.
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.
Nice To Haves
- Experience with sensor or time‑series data (magnetic, radar, 3D, IoT).
- Advanced feature extraction (FFT, windowing, frequency domain).
- Experience with imbalanced datasets and label quality challenges.
- Familiarity with feature importance and interpretability tools
- MLOps experience: MLflow/W&B, CI/CD for ML, drift detection.
- Experience optimizing models for edge devices.
Responsibilities
- 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.
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
- Tuition reimbursement to support your ongoing learning and development
- Subscription to Calm
