Senior QA Engineer

Accountabilities

• Embed fully within an engineering squad, participating in sprint planning, daily standups, reviews, retrospectives, and other ceremonies as a core technical contributor.

• Define and refineacceptance criteriawith Product Owners, identifying ambiguity and quality risks before implementation begins.

• Own the squad’stest architecture and strategy, determining how unit, integration, contract, and end-to-end testing work together and identifying coverage gaps.

• Leadperformance and load testing, establishing baselines, evaluating throughput and concurrency limits, and translating findings into actionable engineering improvements.

• Own the squad’sDefinition of Done and quality gates, serving as a final internal quality check before releases progress to staging or production.

• Design, maintain, and improveautomated test suitesthat remain reliable, readable, maintainable, and effective within CI environments.

• Triage complex test failures and distinguishflaky tests from genuine regressions, particularly across high-traffic, high-risk, or highly integrated areas.

• Mentor QA Engineers within the squad and across the wider QA community, raising standards around automation, test design, and engineering practices.

• Represent the squad in broader QA initiatives and contribute tochapter-wide standards, tooling decisions, onboarding resources, and testing practices.

• Take ownership of a strategic QA initiative, such as a contract-testing framework, performance-testing toolkit, testing discipline, or AI-assisted test generation workflow.

• Actively leverageAI and LLM toolingfor test case generation, synthetic data creation, regression triage, documentation, and other areas where automation can accelerate QA work.

Requirements:

• 5+ years of QA engineering experiencein a software product environment, with demonstrated ownership of testing strategy for complex technical domains.

• Strongtest automation engineeringskills, with the ability to write production-quality tests inJava, Python, or JavaScriptand build stable, maintainable suites that run effectively in CI.

• Deep experience withAPI testing, including REST APIs, contract testing, integration testing, HTTP semantics, and JSON schema validation.

• Hands-on experience withperformance and load testing, including designing tests, interpreting throughput and concurrency results, identifying bottlenecks, and translating findings into engineering action.

• Strong experience working inJava-based backend environments, with the ability to understand application architecture, read Java code, and create tests that accurately reflect system behavior.

• High level of technical autonomy and confidence operating without a dedicated QA manager, with the ability to make sound quality decisions and represent QA practices across teams.

• Proven ability tomentor other QA engineers, improve engineering standards, and lead through technical expertise rather than formal authority.

• Experience infintech, payments, or digital financial servicesis strongly preferred, particularly where reliability and correctness are critical.

• Familiarity withcontract testing tools such as Pactor equivalent approaches within microservices environments is a strong advantage.

• Mobile testing experience, particularlyAndroid, using tools such as Espresso or Appium, or structured manual testing supported by regression frameworks, is beneficial.

• Experience contributing to aQA chapter, guild, community of practice, or internal training programis valued.

• Familiarity withAI-assisted QA workflows, including LLM-based test generation, regression analysis, and synthetic test data creation, is a plus.

Benefits:

• Opportunity to work as asenior technical individual contributorwith substantial ownership and influence.

• Full integration into a product squad, with a direct role in engineering decisions and product delivery rather than functioning as a downstream QA resource.

• Opportunity to shapetesting standards, architecture, tooling, and quality practicesbeyond your immediate squad.

• Strong platform fortechnical leadership and mentoringwithout requiring a transition into people management.

• Exposure to complex, high-scalefintech and digital financial services systemswhere software quality has a direct customer and business impact.

• Opportunity to lead organization-wide QA initiatives and introduce improved testing disciplines and tooling.

• Flexible European-based working environment with collaboration across international engineering teams.

• Opportunity to work withAI-assisted testing and modern QA automation practicesas part of an evolving engineering environment.
