Skills: Quality Engineering, Test Strategy, API Testing, Playwright, Automation
Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
The Quality Engineer will own the test strategy and quality assurance for backend platform services, operator integrations, and vendor dependencies. They will collaborate with engineering teams to implement automated testing, shift-left practices, and robust quality gates throughout the SDLC.
Candidates must have extensive experience in backend and API testing, with proficiency in automation tools like Playwright and a deep understanding of distributed systems. A zero-defect mindset and the ability to operate through a fully registered limited company are required for this contract role.
We are seeking an iGaming Platform Quality Engineer to join our team on a contractual basis. The role is fully remote, with occasional travel required to our headquarters in Málaga, Spain.
This is 6 months extendable contract and applicants must operate through a fully registered limited company to be considered for this role.
We build the backend platforms and services that power our iGaming products and connect our games to operators, aggregators, suppliers, and other external partners.
As an iGaming Platform Quality Engineer, you'll be embedded within our Backend Platform capability, owning quality across the lifecycle of platform services, common iGaming features, and operator and vendor integrations.
You'll work at the intersection of backend engineering, platform architecture, product, integration engineering, and regulatory requirements — ensuring our services and integrations are functionally correct, resilient, scalable, observable, and production-ready.
Quality is built in from the start. You'll work closely with engineers to define test strategies early, automate validation wherever practical, and establish quality gates that provide fast feedback throughout the SDLC.
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.

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 the ability to interpret 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 a language such as Java, JavaScript/TypeScript, Python, or similar.
Experience applying AI tools to quality engineering and test automation.
Quality is an engineering responsibility to you — you don't see testing as something that happens after development is complete.
You think beyond the happy path and naturally ask: What happens if this service is unavailable? What happens if the request is duplicated? What happens if an operator responds slowly?
You understand that in iGaming, seemingly small backend defects can affect player experience, financial transactions, operators, regulatory compliance, and revenue.
You're automation-minded and look for opportunities to turn repetitive validation into reliable, maintainable automated tests.
You're comfortable investigating issues across multiple systems using APIs, logs, data, metrics, and traces, rather than treating the system as a black box.
You're collaborative by nature and work closely with backend engineers, platform engineers, product teams, integration teams, Service Operations, and external partners.
You're comfortable working with ambiguity and can translate complex platform or integration requirements into a clear, risk-based test strategy.
You're a clear communicator who writes precise defect reports, explains risk effectively, and constructively challenges requirements or designs when quality concerns arise.
Most importantly, you have a zero-defect mindset: you continuously look for ways to prevent defects rather than simply finding them later.
