Senior Automation QA Engineer (Contract)

Senior Automation QA Engineer (Contract)

Location and basis

Contractors engage on a B2B basis.

Fully flexible working: home office or a mix your call. We just ask that youre based within one of these areas:

• Bulgaria: within 50 miles of Sofia

Applications from outside these areas wont be considered.

The engagement

Youll join a high-volume online marketplace part-way through a major multi-year technology transformation. Theres 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.

Youll embed directly into one of our product squads as its quality engineer working alongside a tech lead a principal engineer three full-stack engineers and a platform engineer. Youll be the quality lead for that squad owning test coverage automation and validation standards for the features it ships.

Day to day youll write and maintain automated tests shape the squads test approach and hold quality high while the platform changes underneath you.

This is a capacity role alongside an established permanent team. Youll work in a blended squad of permanent and contract colleagues so youll 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.

Youll do well here if youre comfortable with ambiguity and shifting ground.
