SierTeK Ltd.
- Beavercreek, OH
- Permanent
- Full-time
- Develop, deploy, and fine-tune novel unsupervised, tree-based clustering machine learning models
- Accurately explain and code from scratch:
- Decision Trees
- K-Nearest Neighbors (KNN) algorithm
- Must explain the difference between density-based and binning-based clustering techniques
- For KNN:
- Able to implement naive version from scratch
- If unable to optimize the implementation, must clearly explain optimized versions (e.g., KD-Tree, Ball Tree, Approximate Nearest Neighbor techniques
- Write an optimized list sorting algorithm from scratch within 1 hour without external references
- Generate and minimize distance matrices in code (including writing vectorized implementations)
- Obtain HIPAA training upon beginning work
- Maintain strict HIPAA compliance to prevent any data breaches or leaks
