Senior Data Analytics Engineer

You will design and operate the data pipelines that feed CSS intelligence, spanning both batch processing at organizational volume and near real-time streams where detection latency matters. That includes ingesting case and agent telemetry, integrating with the unified data platform and Finance systems, and building the scoring pipelines that run our data science models continuously in production rather than in a notebook. You will be accountable for the reliability of those pipelines: monitoring, alerting on your own infrastructure, handling schema drift and late-arriving data, and making sure a failure surfaces to you before it surfaces to a leader reading a brief. You will build and own the semantic layer that sits between raw data and every consuming experience. This means dimensional models designed for the questions leaders actually ask, certified measures with documented definitions and clear ownership, consistent hierarchies across organization, product, offering, severity, and geography, and the security context that governs who sees what. Critically, you will design this layer to serve more than reports: our detection engine queries it for baselines and thresholds, and our executive experience queries it through a semantic API so that natural-language answers resolve to governed measures with a traceable query path rather than to improvised calculations. You will make trust in the platform mechanical rather than aspirational. You will build data quality and observability into the pipelines themselves, including freshness stamps, reconciliation tests against sources of record, contract checks between producers and consumers, and lineage that lets anyone trace a number on a slide back to the rows behind it. You will bring engineering discipline to analytics through source control, deployment pipelines, environment separation, and infrastructure defined as code, and you will manage platform cost and performance deliberately through partitioning, incremental refresh, and query optimization. You will work in close partnership with data scientists and applied AI engineers, turning experimental models into production services and preparing data for AI consumption, including the grounding, retrieval, and feature-serving patterns our agents depend on. You will also design for handoff: our intent is that patterns proven inside CSS can be adopted and operated more broadly, so schemas, APIs, deployment approaches, and documentation need to be legible to teams who did not build them. Core Skills & Experiences the ideal candidate will possess: Deep SQL expertise and strong programming skills in Python, including experience with distributed processing frameworks such as Spark or PySpark. Strong dimensional and semantic modeling skills, including star schema design, tabular or semantic models, calculation languages such as DAX, and the discipline of certified, documented, single-definition measures. Experience designing layered data architectures that separate raw, conformed, and serving tiers, and knowing which transformations belong in which tier. Experience exposing data and measures programmatically through APIs or query services for consumption by applications, services, or AI agents, not only by reporting tools. Experience implementing data quality and observability practices, including reconciliation testing, data contracts, freshness and completeness monitoring, anomaly detection on pipelines, and end-to-end lineage. Experience applying software engineering discipline to data work, including source control, CI/CD and deployment pipelines, environment separation, code review, and infrastructure as code. Experience optimizing platform cost and performance through partitioning, incremental refresh, aggregation strategy, capacity management, and query tuning. Familiarity with preparing data for AI and machine learning consumption, such as feature pipelines for model scoring, grounding and retrieval patterns for language models, embedding or vector stores, and ingestion of agent telemetry including identifiers, token usage, and evaluation output. Experience partnering with data scientists to productionize models, and with business stakeholders to translate an operational question into a durable data design. A platform mindset: a bias toward building reusable, documented capability rather than one-off extracts, and the judgment to know when a governed measure already answers the question. Comfort operating with autonomy on a small team, owning a component end to end, and writing the documentation that lets someone else run it.
