Описание вакансии

Andersen is hiring a Full Stack QA Engineer (Java/Kotlin) for a project developing a scalable data collection platform and ensuring reliable AI data pipelines, integrations, and quality control.

The customer is a global investment management firm providing tailored investment solutions to institutional and private clients. It combines financial expertise with long-term investment strategies to help clients achieve their objectives while adapting to changing market conditions. The organization focuses on innovation, responsible investing, and operational excellence, continuously enhancing its capabilities to deliver sustainable value and support long-term growth.

The project is focused on developing a scalable data collection platform that supports end-to-end AI data pipelines across multiple countries. It includes campaign and task management, media submissions, automated quality control, worker payments, and dataset delivery, with integrations across internal systems and AI services to ensure efficient and reliable data operations.

Responsibilities:

• Owning the test strategy for a data-collection platform spanning the worker app (WebView inside the main app), the back office, and backend services, from test plans through release sign-off.
• Testing media capture and upload in real-world conditions: photo, voice, video, and text across a wide range of Android/iOS devices, poor networks, interrupted and resumed uploads, and on-device pre-checks.
• Verifying complex business flows and state machines: task reservation and expiry, submission statuses, review and rework cycles, labeling consensus, and buyer isolation between segments.
• Ensuring correctness of money and compliance flows: accruals, balances, payout batches and reconciliation, consent versioning and withdrawal, data erasure, and audit trails for every action.
• Building and maintaining end-to-end and API test automation in CI, plus load testing of the task queue and ingestion under peak traffic (e.g. after mass push notifications).

Must-haves:

• Experience as a Full Stack QA Engineer for 3+ years.
• Experience in functional, integration, API, and E2E testing across the full user journey: onboarding and consent, task queue, data capture and upload, review, earnings, and payouts
• Automation experience in Java/Kotlin.
• Strong experience in API automation (REST and/or gRPC), including tools such as Postman.
• Experience working with Selenium/Selenide.
• Hands-on experience with Appium.
• Understanding of microservices and event-driven architecture: retries, timeouts, idempotency, duplicate events, eventual consistency.
• Experience testing financial flows: accruals, balances, batch payouts, reconciliation with third-party payout providers.
• Understanding of data privacy requirements: consent management, data retention, erasure.
• Experience testing time- and quota-based logic: TTL-based task reservations, expiry and reassignment, volume limits, targeting by country/language/segment.
• Ability to investigate issues using logs, metrics, traces, databases, and message queues (Grafana, CloudWatch, Kibana, Kafka, SQL/MySQL).
• Experience working with CI/CD, Docker, AWS-based environments.
• Ability to validate consistency across the mobile app, WebView, back office, backend APIs, distributed services, and troubleshoot partial failures and partner/service outages.
• Experience contributing to test strategy, requirements reviews, release validation, and production issue analysis with a focus on business risk.
• Level of English – from Intermediate+ and above.

Nice-to-haves:

• Knowledge of JavaScript/TypeScript for automation.
• Knowledge of Playwright/Cypress.
• Experience testing media capture and upload on mobile devices (photo, voice, video, text): device fragmentation, permissions, unstable networks, resumable uploads, on-device validation.
• Experience testing integrations with external services: authentication, CRM, push notifications, payout partners, LLM providers, cloud storage (S3).
• Experience with load and performance testing.

Reasons why this job would be interesting to you:

• Experience in teamwork with leaders in FinTech, Healthcare, Retail, Telecom, and others. Andersen cooperates with such businesses as Samsung, Siemens, Johnson & Johnson, BNP Paribas, Ryanair, Mercedes, TUI, Verivox, Allianz, T-Systems, etc..
