Most QA work is keeping a stable system stable. This is different. You'll hold quality high on a large-scale marketplace that's being rebuilt and migrated while it runs. There's a live migration from GCP to AWS and a full version 2 build underway.This is an initial 3 to 6 month contract, starting as soon as possible.You'll embed into one of our product squads as its quality engineer, alongside a tech lead, a principal engineer, three full-stack engineers and a platform engineer. You'll be the squad's quality lead, owning test coverage, automation and validation standards for everything it ships.Day to day, you'll write and maintain automated tests, shape the squad's test approach, help manage releases and improve how we deploy.This is a capacity role alongside an established permanent team, so you'll need to be productive quickly without a long ramp.The platformThis is a large-scale marketplace. Very few platforms handle a product catalogue or transaction volume at this level.It runs on PHP and Laravel today, moving towards a service-based architecture in TypeScript and Node, so you'll be testing across both as the stack shifts.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. Much of this is being attempted at volumes rarely tested in a marketplace before, so the work leans research-led rather than routine.Who This SuitsA fast-paced environment where the ground shifts. You'll do well if you're comfortable with ambiguity and can hold a standard while things move around you.Location and basisContractors engage on a B2B basis.Fully flexible working: home, office, or a mix, your call.
