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 you're based within one of these areas:

• Bulgaria: within 50 miles of Sofia

Applications from outside these areas won't be considered.

The engagement

You'll join a high-volume online marketplace part-way through a major, multi-year technology transformation. 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 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. You'll be the quality lead for that squad, owning test coverage, automation and validation standards for the features it ships.

Day to day, you'll write and maintain automated tests, shape the squad's test approach, and hold quality high while the platform changes underneath you.

This is a capacity role alongside an established permanent team. You'll work in a blended squad of permanent and contract colleagues, so 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're comfortable with ambiguity and shifting ground.

What we need

The essentials:

• 5+ years across manual and automated testing, operating at a senior level with the autonomy to set standards and deliver without close oversight

• Deep expertise in at least one language (TypeScript, Java, C# or Python)

• You can build, maintain and extend automated tests and frameworks

• Strong grasp of SDLC QA processes: planning, test cases, bug tracking, reporting

• Hands-on with a test case management system such as TestRail

• Solid test methodologies and techniques

• Comfortable working in English, written and spoken

Also needed:

• Working understanding of OOP principles and design patterns

• Good knowledge of CI/CD systems

• Experience with test reporting tools and services

Nice to have:

• Playwright with TypeScript used professionally

• Hands-on with AWS

• GenAI tools already part of your day-to-day QA workflow
