Department: Outsourcing Services

Location: Zagreb, Banja Luka, Sarajevo, Podgorica, Belgrade, Nis, Novi Sad, Skopje Office, Krakow, Warsaw, Wroclaw, Bucharest, Cluj-Napoca, Iași, Timișoara

Employment Type: FullTime

We’re looking for a Senior SDET to join a project at a leading data-intelligence company that enables organisations to “do more with trusted data”. Their platform spans data catalog, governance, quality, AI governance and observability — helping businesses turn data into a strategic asset.
In this role, you’ll combine deep test engineering competence with strong software engineering skills. You’ll build automation frameworks, drive a shift-left testing mindset across Agile teams, and help raise the bar for quality across the stack.

What you will do:

• Design, develop and maintain automated test frameworks and scripts (Java, Playwright/TypeScript) for UI, API and backend-oriented systems.

• Integrate and optimise CI/CD pipelines to ensure automated testing is embedded into the delivery flow.

• Define what to test, how to test it and when — guide the team on test strategy (smoke, regression, end-to-end).

• Collaborate with developers, product managers and operations to troubleshoot defects, improve observability/testability and reduce bottlenecks.

• Perform exploratory testing, analyse customer-reported issues and use findings to enhance automation coverage and test design.

• Advocate for quality: you’ll initiate improvements in test practices, help build culture and push for continuous improvement.

Requirements:

• Extensive experience in test engineering with strong software engineering capability.

• Proven ability to write, maintain and refactor automated tests/frameworks in Java and/or Python.

• Hands-on experience with Playwright/Typescript.

• Solid experience working with CI/CD pipelines, GitHub Actions/Jenkins or similar.

• Familiarity with cloud environments (AWS/GCP), containerisation (Docker) and orchestration (Kubernetes).

• Familiarity with networking and security controls (e.g. authentication mechanisms).

• Quickly acquires necessary domain knowledge

• Understands non-functional requirements for our product and advocates for proper treatment of these areas

• Understands the open-domain problem and its implications for quality assurance

• Strong troubleshooting skills: reading stack traces, detecting flaky results, isolating root causes of failures.

• You are self-driven, proactive and able to operate with minimal guidance.

• Good communication and collaboration skills — you’ll influence across engineering, product and QA.

• English fluency (written & spoken).

Nice to have:

• Experience in data governance, metadata platforms, or data-intelligence solutions.

• API contract testing experience, performance/sub-system testing for large-volume data.

• Experience shaping test dashboards, tracking test metrics, and flaky-test monitoring.

• Exposure to security testing, cloud native QA practices or observability/instrumentation in test frameworks.

Why is this a great opportunity?

• You’ll join a forward-looking team at the intersection of data, AI and enterprise governance, working on a platform used globally to manage data intelligence.

• The role emphasises autonomy: you’ll be trusted to own the SDET agenda, influence test strategy and deliver real impact.

• You’ll work with modern tools: Playwright, Java automation frameworks, cloud environments and shift-left practices.

• You’ll be part of a growth-oriented, high-energy team where quality is a priority and you can elevate testing to be a strategic differentiator.

Working Conditions:

• Long-term 12-month contract with possibility for extension

• Choose your contract: Contract or B2B,

• Unlimited working-from-anywhere policy,

• 10 Days PTO after 4 months of working in IT Labs,

• Referral Bonuses,

• Virtual Knowledge Sharing Sessions, Events and Team Hangouts.
