IT&Data Engineer

1. Role purpose

He/she builds governed, reusable data products — contributing to OneHouse (the central lakehouse) and delivering transformations within Data Transformation Units (DTUs) — while raising the technical bar of the squad through mentoring, design guidance and code quality.

As a chapter member, the role provides technical leadership at squad level, but does not carry people-management, capacity or standard-setting accountabilities — which remain with the Chapter Manager and the Chapter Lead.

Level & reporting note: This is an individual-contributor role at L9. The role reports to the D&A Engineering Chapter Manager (L8), preserving the chapter reporting line (Chapter Lead → Chapter Manager → chapter team member). People-management, staffing and standard-setting are explicitly out of scope to keep the role distinct from the L8 Chapter Manager.

2. Main mission

Ensure, within a squad, the technical quality and reliability of data products delivered on OneSource 2.0 — acting as hands-on technical reference and coach — so that Bronze → Silver → Gold datasets serve as a trusted Single Source of Truth (SSOT), under the guidance of the Chapter Manager.

Responsibilities

Technical leadership at squad level

– Act as the technical reference for the squad’s data engineering work on OneSource 2.0

– Guide solution build within guardrails; drive design and code quality through peer review

– Mentor and upskill junior data engineers; support estimation and technical planning

– Contribute to Engineering Decision Records (EDRs) for implementation-level decisions

Data ingestion (config-driven)

– Configure ingestion using the OneHouse metadata-driven framework: create/modify JSON configuration files (ingestion, Bronze) and deploy via GitHub / GitOps / CI-CD

– Onboard sources (SAP/DB2, files, Snowflake, external push/pull) into OneHouse, ensuring reliability, completeness and lineage

Transformation & data modelling (core value)

– Build Silver (cleaned, harmonized, modelled) and Gold (business aggregations / data products) datasets implementing business KPIs

– Apply and enrich reusable logic from the Transformations Library; document and version it

– Translate KPI definitions into scalable transformations aligned with domain data models

Platform engineering within DTUs

– Develop within DTUs using Databricks (Spark/SQL/Delta Lake) and, where relevant, ADF, Snowflake or Informatica

– Structure data across Bronze / Silver / Gold; optimize performance, cost (FinOps) and scalability

– Apply best practices for CI/CD, IaC, monitoring and data quality checks

Governance & data products

– Verify integrity of ingested data and entities in Unity Catalog; respect GBDO / Data Owner validation and security-by-design

– Ensure only OneHouse-stored, catalogued data is published as shareable, certified data products (SSOT)

Technical requirements

Expertise expected

– Strong Data Engineer experience in enterprise environments, with hands-on OneSource 2.0 / OneHouse & DTU practice

– Databricks (Spark/SQL, Delta Lake) mandatory; ADF / Azure stack; exposure to Snowflake / Informatica a plus

– Solid data modelling for analytics (facts, dimensions, derived metrics) and medallion architecture

– Comfortable with config-as-code / GitHub / CI-CD working model; experience integrating ERP / Finance / Commercial data (e.g. SAP)

Leadership positioning (technical, not managerial)

– Recognized technical reference within the squad; able to coach juniors and justify design choices among competing alternatives

– Operates under the guidance of the Chapter Manager — no people-management, capacity or standard-setting accountability

Additional responsibilities

Building governed Bronze/Silver/Gold data products in OneHouse and DTUs, and coaching junior engineers — while reporting to the L8 Chapter Manager. “Lead” reflects technical seniority, not a management layer, keeping the role cleanly one level below the Chapter Manager in the chapter structure
