Senior Data Engineer; Foundations

The Senior Data Engineer – Platform Foundation is a hands‑on, senior‑level contributor embedded in the Foundations squad. You will design, build, and evolve the shared ingestion platform that underpins data delivery across the company. The platform is the product — your job is to make it reliable, extensible, and easy for other teams to adopt.

The Foundations squad operates across three pillars: simplifying the overall data platform landscape by reducing complexity and consolidating redundant patterns; enabling structured and unstructured data ingestion at scale; and supporting the exposure of data products to consumers across the organization. You contribute to all three — making architectural decisions, writing production code, and enabling other teams through documentation and hands‑on support.

• Design and implement reusable ingestion components using dlt and dbt-core, covering both structured and unstructured data sources, handling high-volume, append-heavy, and schema-drifting patterns
• Own the Airflow platform end-to-end: extend and maintain DAGs and shared operators, handle deployments and version upgrades, and provide hands‑on support to consuming teams
• Ensure incremental loading strategies, data quality checks, and lineage metadata are first‑class outputs of every pipeline

• Identify and eliminate redundant ingestion patterns across consuming teams, drive standardization onto shared Platform Foundation components
• Collaborate with Solution Architects to evolve the platform architecture in response to new data sources and shifting business requirements
• Support data product exposure: define and implement governed interfaces that make data reliably accessible to internal consumers
• Contribute to Terraform‑managed infrastructure; participate in multi‑cloud (AWS / Azure) deployment patterns

• Actively use and evaluate AI‑assisted development tools (Git Hub Copilot, Claude Code, etc.) to accelerate platform Foundation delivery
• Champion AI tooling adoption within the squad; share best practices and guardrails around AI‑generated code review
• Explore AI‑powered capabilities (RAG pipelines, LLM‑assisted data cataloguing) for internal platform documentation and self‑service enablement

• Maintain and improve CI/CD pipelines (Team City, Git Hub Actions) for platform Foundation components
• Define and enforce observability standards: DAG / Task‑level alerting, SLA tracking
• Participate in on‑call rotation for critical ingestion pipelines; drive post‑incident improvements

• Produce platform Foundation documentation, runbooks, and enablement materials for consuming squads
• Translate ambiguous or moving business requirements into concrete technical designs — comfortable challenging scope when needed
• Mentor mid‑level engineers; participate in hiring and technical assessments

• Bachelor's degree in Business, Information Systems, Data/Analytics, Computer Science, or related field
• Minimum 5 years in data engineering roles, with at least 2 years in a senior / platform‑level position
• Proven track record building production ingestion and transformation pipelines at scale
• Experience contributing to a shared platform or internal developer tooling consumed by multiple teams

• Python: idiomatic, testable, production‑grade code — not just scripting
• dbt-core: advanced modelling (custom materializations), testing, documentation, packages
• Apache Airflow: DAG design patterns, custom operators, dynamic task mapping, SLA management
• Cloud data platforms: comfortable with one or more major cloud warehouses (Snowflake, Big Query, Databricks, Microsoft Fabric)
• SQL: complex analytical queries, window functions, query profiling
• Git, CI/CD: trunk‑based development, automated testing gates, pipeline‑as‑code

• Daily user of AI coding assistants (Copilot, Claude Code or equivalent)
• Understands the limits of AI-generated code — applies rigorous review, not blind trust
• Interest in LLM‑powered data tooling (RAG pipelines, Cortex, semantic layers) is a plus
