## About the Role

+ BS or MS in Data Science, Computer Science, Statistics, Applied Mathematics, Engineering, Cybersecurity, or a related quantitative discipline.
 + Strong Python skills and hands-on experience with common scientific/ML tooling such as pandas, NumPy, scikit-learn, SciPy, and related libraries.
 + Strong understanding of unsupervised machine learning, including clustering, anomaly/outlier detection, similarity/distance methods, feature engineering, and statistical baselining.
 + Experience with at least some of the following: graph analytics or graph ML, entity resolution/record linkage, probabilistic modeling, time-series analysis, change-point/concept-drift detection, nearest-neighbor methods, or dimensionality reduction.
 + Experience working with large, noisy, heterogeneous datasets where labels or authoritative ground truth are limited.
 + Familiarity with scalable data processing and efficient model implementation; comfortable thinking about CPU/memory constraints as well as GPU acceleration for larger workloads.
 + Working knowledge of networking and cybersecurity concepts such as IP addressing, DNS, TLS, network flows, ports/services, routing, network devices, and security alerts.
 + Experience with cyber/network telemetry such as Zeek, PCAP-derived data, SIEM data, IDS/IPS alerts, device configuration data, or vulnerability/asset data is highly desirable.
 + Experience with graph/network-analysis libraries, SQL/data stores, Elasticsearch/Splunk, or similar analytic platforms is a plus.
 + Experience developing analytics for cybersecurity, threat hunting, detection engineering, or defensive cyber operations is strongly preferred.

## Description

+ Develop and evaluate machine-learning analytics for cyber defense use cases using network, sensor, alert, asset, and other operational telemetry.
 + Build unsupervised and statistical models for clustering, anomaly/outlier detection, behavioral baselining, novelty detection, and pattern discovery.
 + Apply techniques such as graph analytics/embeddings, nearest-neighbor methods, time-series or periodicity analysis, clustering, dimensionality reduction, and anomaly scoring to large cyber datasets.
 + Design models and features that account for concept drift, noisy data, incomplete ground truth, and high false-positive rates common in operational cyber environments.
 + Support asset discovery and entity resolution, including development of probabilistic asset graphs that associate IPs, hostnames, MAC addresses, services, certificates, device attributes, and other observations across data sources.
 + Develop contextual features from security alerts and network telemetry, including temporal patterns, rarity/frequency, communication behavior, entity context, and related activity, and use those features to identify meaningful alert clusters and outliers.
 + Work with cyber analysts and detection engineers to turn operational questions and adversary behaviors into measurable features, experiments, and analytics.
 + Evaluate model effectiveness using appropriate quantitative metrics and operational validation; benchmark accuracy, false-positive behavior, computational performance, and usefulness to analysts.
 + Develop production-quality Python code and work with engineers to integrate models into sensor-side CPU environments as well as larger GPU-enabled enterprise analytics platforms.
 + Understand the practical strengths and limitations of LLMs: know when to use an LLM, when to use conventional ML/statistics, and when a deterministic rule or query is the better answer.
 + Ability to build evaluation harnesses rather than judge AI output by vibes-test datasets, expected behaviors, regression tests, failure cases, and quantitative measures.
