You have trained models that moved metrics, built pipelines that processed millions of records, and translated statistical uncertainty into decisions business leaders could act on. The hiring bottleneck is not your work — it is whether your resume names that work in the exact language the ATS expects.
Data science job postings are precise about frameworks and methodologies. The gap between a resume that passes ATS and one that does not often comes down to whether you wrote 'PyTorch' or 'deep learning frameworks', 'XGBoost' or 'gradient boosting', 'SageMaker' or 'cloud ML platform'.
ATS systems for data science roles are configured with specific framework names, not categories. PyTorch, TensorFlow, scikit-learn, XGBoost, LightGBM, and Keras are each independent keyword searches. Writing "experience with ML frameworks" scores zero against all of them.
MLOps and deployment vocabulary is increasingly present as a hard filter in DS job postings: MLflow, Kubeflow, SageMaker, Vertex AI, model monitoring, feature stores, CI/CD for ML, and model versioning. If the posting includes these and your resume does not, you will not pass the initial screen regardless of model quality.
Are your ML frameworks and MLOps tools named explicitly on your resume?

Beyond ML, data science roles filter for statistical rigour vocabulary: A/B testing, hypothesis testing, p-value, confidence intervals, Bayesian inference, causal inference, and experimental design. These appear in ATS configurations because they indicate the ability to separate signal from noise — a critical differentiator at senior levels.
LLM and NLP vocabulary has become a hard filter at many companies in 2025–26: LLMs, RAG, fine-tuning, embeddings, prompt engineering, vector databases (Pinecone, Weaviate, FAISS). If the role involves any language model work, these terms must appear in the resume.

A data scientist who writes broadly scores below one who writes precisely. The ATS does not infer capability from seniority signals — it counts keyword matches. Name every framework, every statistical method, and every deployment tool.

The most common reason is category language instead of specific names. "ML frameworks" scores zero against PyTorch, TensorFlow, or XGBoost — each is a separate ATS keyword that must appear by name.
Yes, if you have used both. They are separate keyword hits. Also list scikit-learn, XGBoost, LightGBM, and any other frameworks you have used — each is an independent filter in DS job postings.
MLflow, Kubeflow, SageMaker, Vertex AI, Weights & Biases, DVC, and Airflow are the most common MLOps keywords in DS job postings. List every platform you have deployed to or monitored models on.
