Data Engineer

• ·Build and run the pipelines that move data from wherever it is produced to wherever it is used, on a schedule, without supervision.
• ·Model data — deciding what a customer, an order or an event actually is, so that two teams counting the same thing get the same number.
• ·Design and maintain warehouses and lakes, and make queries over them fast enough and cheap enough to be worth running.
• ·Test data the way software is tested, because a pipeline that runs successfully and produces wrong numbers is the characteristic failure of this job.
• ·Handle the volume and latency problems: batch versus streaming, backfills, and what happens when yesterday's data arrives tomorrow.
• ·Manage access, privacy and retention — who may see what, and what must be deleted when.
• ·Absorb upstream changes made by teams who did not know you existed, which is a permanent feature rather than a phase.
• ·Explain to analysts why the number changed, which is often the most useful hour of the week.

If any of those systems is unfamiliar — or you have not chosen between them yet — the exams and qualifications section covers what each one is, which subject inside it opens which degree, and when to sit what.

Less competitive than data science for the same pay, which is the useful fact about this career and the reason to know it exists. Fewer people want it, because it has none of the glamour and all of the reliability burden, while employers need it more. Entry-level roles are still limited, and the common route in is a year or two adjacent — analytics, backend, or support — before moving across.

Provenance for this sectionestimatedestimatedInferred by reasoning, not measured. The basis is given below.Reasoned from the absence of licensing requirements, published national data and AI strategy direction, and the structural precedence of data infrastructure over analytics in every such programme.

Batch and warehouse engineering

Scheduled pipelines and the analytical warehouse. The largest share of the work and the most portable skill set.

Streaming and real-time

Data that has to be usable in seconds — fraud, logistics, telemetry. Harder, better paid, and fewer employers need it.

Analytics engineering

The layer between raw data and analysts: modelling, definitions and tests. Closer to the business and increasingly its own job title.

Data platform and infrastructure

Building the tooling other data teams use. Overlaps with site reliability engineering and pays like it.

Data governance and privacy

Access, retention and regulatory compliance. Growing quickly wherever data protection law is tightening, including in the Kingdom.

Demand: growingestimatedestimatedInferred by reasoning, not measured. The basis is given below.Inferred from recorded employment in the closest measured occupation combined with consistently reported hiring difficulty. No published occupational projection for this specific role was obtainable.

The closest measured occupation records 67,140 people in the US with a median of $139,500, and demand is structurally tied to the growth of analytics and machine learning rather than competing with them — every model and every dashboard needs this work done first. Practitioner and hiring accounts consistently describe supply as tighter here than in data science.
