Build the data infrastructure behind apps used by billions of people - and own it end to end.
This is a senior data engineering contract with a global technology company whose apps sit on nearly every phone. You'll be embedded in their Marketing & Communications analytics team, designing and scaling the ETL pipelines and data models that decide how marketing performance gets measured across their entire family of apps.
It's a driver's seat, not a passenger one. You'll take projects from architecture through to execution yourself - and you'll be actively encouraged to use AI tools to work faster and smarter.
What's in it for you
- 6-month contract inside IR35 with real, end-to-end ownership
- Fully remote within the UK
- Annual Salary up to £110,000 pro rata (DOE)
- Paid weekly via Principle HR (inside IR35, PAYE)
What you'll need
- 5+ years hands-on in data engineering (or data-heavy roles)
- Strong SQL and Python - used daily, non-negotiable
- Proven experience building and optimising ETL pipelines at serious scale (billions of rows)
- The judgement to design scalable, efficient architecture yourself
- Comfort using AI tools to speed up your coding and data work
- A bonus, not a barrier: exposure to marketing analytics or martech
What your day looks like
- ~80% designing, building and tuning ETL pipelines against enormous datasets
- ~20% building dashboards on internal tooling
- Translating what the marketing and data-science teams need into working data models
- Making the architecture calls - balancing speed, cost and scale
