Solutions Architect at Hedgehog Lab, Remote, £Contract Rate (Outside IR35)

Contract Description

Solutions Architect (Outside IR35)

The engagement

We're building out a team to work with a client on a major data and cloud migration for their marketplace platform.

You'll be the Solutions Architect on it: owning the target-state data architecture on AWS, and the plan to get there without disrupting a live platform running at serious volume.

That means owning the migration end to end: how the data moves, in what order, how it's cleaned and reconciled along the way, and how you cut over with as little downtime as possible.

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

You work comfortably across data and cloud, and you've owned migration planning start to finish before.

You can hold the detail of dependency mapping and cutover sequencing while keeping the wider architecture in view.

You've done this on AWS, at scale, on systems that can't afford much downtime.

What we need

The essentials:

  • A strong blend of data and cloud migration experience

  • Hands-on experience designing target-state data architecture on AWS

  • Data migration planning: dependency mapping, data cleansing, reconciliation, cutover, rollback and low-downtime migration

Nice to have:

  • Ecommerce experience


Location and basis

Contract, outside IR35. Starting as soon as possible.

While there's no set number of days you're required on site, there will be times when the client needs the team together in person for important meetings, workshops and key moments. When that's the case, we'd expect you to attend.

To make that work, you'll need to be based within 50 miles of one of our offices in Edinburgh, Newcastle, Leeds, Manchester or London.
