Job summary

Expenti is seeking an iGaming Platform Quality Engineer for a 6-month contract with remote work and periodic travel to Málaga, Spain. You will own QA across backend platform services, operator and vendor integration, and platform changes, designing tests and ensuring production readiness.

Responsibilities include API, integration, end-to-end, and contract testing, shift-left practices, and AI-assisted quality engineering to accelerate validation and root-cause analysis.

Qualifications

• Experience testing backend platforms in regulated iGaming, payments, fintech, or other high-transaction environments.
• Understanding of iGaming wallet and transactional flows, including debit, credit, rollback, refunds, retries, duplicate transactions, and idempotency.
• Experience with contract testing and API automation frameworks.
• Experience testing event-driven architectures, queues, or messaging platforms.
• Knowledge of performance/load testing and interpreting service performance metrics.
• Experience with cloud-based platforms and services such as AWS.
• Understanding of observability tooling, including logs, metrics, distributed tracing, dashboards, and alerting.
• Experience working directly with operators, aggregators, game suppliers, or other third-party integrations.
• Scripting or development experience in Java, JavaScript/TypeScript, Python, or similar
• Experience applying AI tools to quality engineering and test automation.

Responsibilities

• Own test strategy and quality assurance for backend platform services, common iGaming capabilities, operator integrations, vendor/supplier integrations, and platform changes.
• Design and execute API, integration, end-to-end, regression, and contract testing across services and external integrations.
• Validate common iGaming platform features such as game launch, session management, player authentication, wallet interactions, bet/win transactions, game configuration, limits, currencies, languages, and jurisdiction-specific behaviour
• Test operator and aggregator integrations, validating request/response flows, authentication, configuration, error handling, transaction integrity, retries, idempotency, and integration-specific behaviour.
• Validate third-party and vendor integrations, ensuring external dependencies behave correctly across happy paths, failure scenarios, degraded services, timeouts, and unexpected responses.
• Build and maintain automated API and integration regression suites using Playwright and other appropriate testing tools , providing rapid feedback on critical platform and integration journeys.
• Work closely with developers to adopt a shift-left and zero-defect mindset, reviewing requirements, specifications, acceptance criteria, API contracts, and technical designs before implementation begins.
• Use AI-assisted quality engineering to accelerate test strategy creation, test-case generation, automation, exploratory testing, and defect/root-cause analysis while maintaining engineering judgement and appropriate validation.
• Validate data integrity and transactional consistency across distributed services, particularly where player balances, bets, wins, refunds, rollbacks, or other financial transactions are involved.
• Test platform resilience by validating scenarios including service failures, timeouts, retries, duplicate requests, partial failures, dependency failures, and recovery behaviour
• Support performance and scalability testing for critical APIs and platform services, identifying potential bottlenecks and degradation under load.
• Ensure appropriate logging, metrics, tracing, and alerting exist for critical journeys so failures can be detected, diagnosed, and resolved effectively in production.
• Integrate automated tests and quality gates into CI/CD pipelines, defining clear pass/fail criteria for API, integration, regression, smoke, and other appropriate automated checks.
• Support release and production assurance through risk-based testing, pre-release validation, post-deployment sanity checks, and production verification
• Participate in architecture/design reviews, refinement, and planning, raising testability, operability, resilience, and quality concerns early and contributing to Definition of Done standards.
• Collaborate with Engineering, Product, Service Operations, Compliance, operators, and external suppliers to investigate and resolve integration and production issues.
