Podsumowanie oferty

You will own quality and verification for migrating a large portfolio of legacy desktop business applications into modern web solutions on an established financial software platform. You will define verification approaches and build automated quality gates in an AI-assisted workflow, using TypeScript.

Wymagania

5+ years in quality engineering, including verification of legacy system migrations or rewrites, such as characterization testing, golden master testing or parity testing.
Specification-based test design and traceability, for example with BDD, acceptance criteria or requirements-based testing.
Strong test automation skills in TypeScript.
REST API testing, including contract and schema validation and data-driven tests.
Web E2E testing; Playwright is preferred.
Good SQL skills and experience validating data in business applications.
Hands-on use of AI coding tools such as Claude Code, Cursor or GitHub Copilot in QA work, and the ability to critically evaluate AI-generated code and tests.
Experience with mutation testing, fault injection or other methods of measuring how effective tests are.
Experience testing data-intensive business systems, ideally in finance or ERP.
Fluent English.
Practical experience using AI-powered assistants such as Claude Code, GitHub Copilot or Cursor to improve productivity, quality or decision-making in software delivery.

Nice to have:

Experience evaluating LLM output, such as eval harnesses or LLM-as-judge setups.
Snapshot, approval, visual regression or property-based testing.
Testing multi-tenant or single-tenant-per-customer deployments.
Performance and batch processing testing.
Mutation testing tools such as Stryker or PIT.
Working knowledge of Docker and CI/CD pipelines, and setting up isolated test environments.
Experience applying GenAI in a more structured way within the SDLC, including defined workflows, prompt patterns or tool integrations embedded into daily work.
Interest in and familiarity with emerging AI-driven practices such as agent-based workflows, automation patterns and AI-augmented development, with a willingness to explore and experiment beyond standard approaches.
