Tech Lead (AWS / TypeScript / Python)
Location and basis
Contract, outside IR35. Starting as soon as possible.
Fully flexible working: home, office, or a mix, your call. We just ask that you're based within 50 miles of Edinburgh, Newcastle, Leeds, Manchester or London.
Applications from outside these areas won't be considered.
The engagement
You'll lead engineering on a high-volume online marketplace, part-way through a major, multi-year technology transformation. There's a live migration to AWS and a full version 2 build underway.
The current client-facing platform runs on PHP and Laravel, and the target is a service-based architecture on AWS built in TypeScript, JavaScript and Python. You'll set technical direction across that shift while keeping delivery moving.
You'll need to be hands-on and broad: someone who understands cloud, architecture, data, auth, front-end and APIs, and has built service-based platforms in AWS before. In an older structure this person would have carried an architect title.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This is a demanding, fast-paced environment. You'll need to be productive quickly without a long ramp.
The platform
This is a genuinely large-scale marketplace. Very few platforms handle a product catalogue or transaction volume at this level.
The roadmap includes agentic AI workflows built into the platform, retail media integrated directly into the marketplace, and infrastructure work targeting cost and performance at high volume.
A lot of this is being attempted at volumes that have rarely been tested in a marketplace before, so the work leans research-led rather than routine.
Who this suits
This is a fast-paced scale-up environment on a complex platform.
You'll do well here if you think strategically rather than transactionally, and you can advocate for technical change and bring people with you.
