- Hands-on experience developing and evaluating machine-learning, data-mining, computer-vision, or information-retrieval methods using a framework such as PyTorch or TensorFlow.
- Understanding of model uncertainty and evaluation, embeddings and similarity search, and how training-data composition affects model behavior.
- Preferred experience with backend services, REST APIs, relational data modeling, SQL, and JavaScript or TypeScript frontend development using React or a comparable framework.
- Preferred experience with training or fine-tuning, active learning, data flywheels, hard-example mining, uncertainty or disagreement signals, dataset curation, autonomous driving, robotics, or perception.
- Preferred experience with CLIP-style models, VLMs, vector databases such as Milvus, FAISS, or pgvector, or GPU batch inference at scale.
- Strong ownership, learning ability, and willingness to drive projects end to end.
