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)
Please note: For this opportunity we can only consider candidates physically based in the UK with existing right to work. We're not able to look at applicants based overseas or who'd need sponsorship.
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
