Senior QA Automation Engineer (PHP) - B2B Contract

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 platform

This 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.

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 suits

A 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 basis

Contractors engage on a B2B basis.

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

• Bulgaria: within 80km of Sofia

Applications from outside these areas won't be considered.

What we need

The essentials:

• 4+ years in manual and automated testing

• Solid PHP experience

• Confident across automated testing, and can build, maintain and extend test frameworks

• Hands-on experience with Cypress

• Comfortable working in English, written and spoken

Also needed:

• Working understanding of OOP principles and design patterns

• Good knowledge of CI/CD systems
