Whimsy Games

Whimsy Games is looking for a QA Engineer to ensure quality and stability of our gambling platform. Focus on Frontend (React/Next.js, TypeScript, REST) and Backend (NestJS, PostgreSQL, Redis, RabbitMQ), including documentation testing. Fast-paced environment, real impact, and a great opportunity for a Manual QA ready to grow into Automation or an AQA to make a difference.

Responsibilities

• Documentation Review: Assist in analyzing business goals, technical documentation, and law requirements to identify "logic holes," gaps, or missing edge cases before development starts.
• Data Flow Monitoring: Trace the data flow from the Frontend (React/Next.js) to the Backend (NestJS) to ensure correct processing.
• SQL Data Verification: Use SQL (AI tools may be used for generation, but understanding the logic and execution is a must-have) to verify that "real" data in PostgreSQL matches business logic.
• Infrastructure Monitoring: Audit Redis (cache/locks) and RabbitMQ (queues) to ensure no data is lost or stuck (AI tools may be used for analysis or command generation, but a fundamental understanding of how these systems operate is a must-have).
• Technical Reporting: Write high-quality technical bug reports that identify why a failure happened (e.g., a database deadlock, a message queue error, or a cache sync issue).
• Load Test Execution: Design load tests (AI tools may be used to generate scripts and scenarios, but a fundamental understanding of performance metrics and system behavior is a must-have) to simulate thousands of concurrent users and identify backend bottlenecks.
  
  Requirements:
  • Experience: 3+ year in QA roles with a strong technical background and understanding of high-traffic or high-concurrency systems.
  • Stack Knowledge: Basic understanding of frontend and backend concepts and architecture. (we use React/Next.js and NestJS)
  • System Basics: Basic knowledge of microservices and how message brokers (e.g., RabbitMQ or Kafka) handle communication between services.
  • Caching: Fundamental understanding of how distributed cache (e.g., Redis) is used for caching.
  • Performance Testing: Basic experience or theoretical knowledge of performance tools such as K6, JMeter, or similar.
  • AI-Native Workflow: Proven ability to use LLMs and AI coding assistants to generate test cases, analyze documentation, and audit backend source code.
  
  Soft Skills & Process:
• Shift-Left Mindset: A strong belief that quality starts at the "Idea" phase. You are proactive in preventing bugs during the design stage.
• Concurrency Awareness: The ability to visualize and test for complex Race Conditions (AI tools can assist in finding them, but you must understand the concept).
• Technical Communication: Ability to explain technical failures clearly to developers.
