Senior Data Engineer

The Senior Data Engineer owns that substrate end to end: ingestion from messy third-party APIs, modeling and governance in Unity Catalog, the serving layer agents query at runtime, and the health monitoring that tells us something broke before a CSM finds out in a client meeting. Infrastructure is code, deploys go through CI/CD, and quality is measured — not assumed. You write the Terraform, you own the alerts, you get paged by your own monitors.

REQUIREMENTS:

• Strong software engineering fundamentals in Python and advanced SQL — this role builds tested, deployed, version-controlled pipelines, not one-off notebooks
• Deep hands-on experience with Databricks: Spark/PySpark, Delta Lake, Unity Catalog, Workflows, and SQL warehouses, including performance tuning of real workloads
• Proven experience designing data pipelines and data models in production: medallion or equivalent layered architectures, incremental processing, CDC, and dimensional modeling
• Experience integrating third-party APIs at scale, with the operational maturity that implies (auth, pagination, throttling, partial failure, backfills, idempotency, schema evolution)
• Familiarity with cloud platforms (we run on Azure — ADLS, Container Apps, Key Vault, API Management, Entra ID)
• Experience with Infrastructure as Code (Terraform) and CI/CD pipelines, plus solid git and code-review habits
• A working definition of data quality: tests, expectations, monitoring, and the discipline to catch problems upstream rather than explaining them downstream
• Practical experience using AI coding assistants/agents in real engineering work, and the critical eye to know when their output is wrong
• Excellent problem-solving and analytical skills, and the autonomy expected of a senior engineer: you own a problem end to end — from framing to shipped, monitored outcome — and are accountable for the result, not just the merge
• Bachelor's degree or higher in Computer Science, Information Technology, or a related field — or equivalent practical experience

PREFERRED QUALIFICATIONS:

• Experience serving data to LLM-powered applications, including retrieval and context design
• Experience with operational stores alongside the lakehouse (Databricks Lakebase, PostgreSQL, MongoDB)
• Observability stacks: OpenTelemetry, Grafana, Loki, structured logging
• Delta Sharing for secure data exchange with clients and partners
• Domain background in retail media, digital advertising, or marketplace data
• Databricks or Azure certifications

WHAT YOU’LL DO:

• Design, build, and operate ingestion pipelines from advertising and business platforms (Amazon Ads, Google Ads, Walmart Connect, Criteo, Salesforce, and internal services) via REST APIs, Delta Sharing, object storage, and event streams
• Model curated data layers in Delta Lake under Unity Catalog: medallion architecture, incremental and CDC patterns, clear contracts between layers, lineage, and row/column-level governance
• Build the serving layer for AI: SQL views, Unity Catalog functions, and low-latency stores exposed to agents as tools through the Model Context Protocol (MCP) behind Azure API Management — designing for what an agent needs to reason well, not just for what a BI tool needs to render
• Own data quality and health monitoring as code: freshness, volume, schema-drift and business-rule expectations, with alerting wired into Grafana and a clear triage path when something fires
• Ship everything through Terraform and CI/CD — Databricks and Azure resources, jobs, permissions, and environment promotion from dev to prod, with no manual clicking in the console
• Own performance and cost: warehouse and cluster sizing, partitioning and liquid clustering, job orchestration in Databricks Workflows / Lakeflow, and continuous scrutiny of what each pipeline actually costs to run
• Work fluently with AI coding agents as part of your daily engineering practice — writing precise specs, keeping repository context and documentation in a state where agents produce good output, and reviewing what they generate with real judgment
• Collaborate with cross-functional teams — AI engineers, software engineers, and product — turning product requirements into data the platform can actually serve, and treating internal consumers as customers with contracts and expectations
• Instrument what you ship with OpenTelemetry and structured logging, and improve reliability and latency in production
• Document and maintain the codebase, ensuring code quality and adherence to best practices
