Quality Assurance Engineer - Test Automation (ref5206f) - Remote Eligible

Quality Assurance Engineer - Test Automation

Are you a quality advocate who loves discovering edge cases in complex synchronization logic? Do you think about how software behaves when networks fail, packets drop, and servers lag? Join our team to ensure the absolute reliability of our edge-twin platform. If you enjoy building automated simulations for offline recovery and eventual consistency, we want you on our team!

Our project, GroundOS, is not just another screen manager. It is a next-generation Universal Display System (UDS) built to power the future of global mobility. We are building an "Operating System for Reality" that orchestrates massive, data-driven signage networks across critical infrastructure, from major international airports to sprawling public transport systems. GroundOS moves beyond static displays; it uses a state-of-the-art digital twin to process and react to real-time operational data. To guarantee continuous operation, the platform features a resilient, offline-first edge architecture that ensures screens keep running smoothly even if the network fails. Join us to blend high-performance Rust edge computing with modern TypeScript cloud services, and help us set a new global standard for how hundreds of millions of passengers experience their journey.

Tasks:

• Build and maintain modern End-to-End (E2E) test automation frameworks for complex UI and data flows.
• Mock Connect RPC calls and NATS messaging to accurately simulate backend behaviors.
• Design and execute network simulations to test "flaky" connections, packet loss, high latency, and total disconnections.
• Perform performance and load testing by simulating thousands of concurrent clients hitting the backend.
• Discover and document edge cases and race conditions in synchronization logic.
• Verify data integrity to ensure locally cached data eventually matches server data (Eventual Consistency testing).
• Advocate for testability during the initial design phases, not just post-development.
• Document clear, reproducible steps for complex concurrency bugs.

Hardware/ SW Testing:

• Test Automation Frameworks
• Network Simulation
• Performance & Load Testing
• Operational & Architecture Skills
• Leadership & Soft Skills

Qualifications

• Strong proficiency in modern test automation frameworks and E2E tools.
• Experience testing distributed systems and Eventual Consistency models.
• Hands-on experience with network simulation and chaos engineering concepts.
• Ability to use load-testing tools to simulate high-concurrency environments.
• Excellent analytical skills and attention to detail.
• Strong communication skills to clearly report complex, hard-to-reproduce bugs to engineering teams.
• At least 5 years of experience in a similar position
• Expert knowledge of agile development
• Solid knowledge of Scrum
• Experience working in agile projects and teams
• Good knowledge of Linux
• Experience with Git and Jira
• Excellent English skills, both written and spoken (B2–C1)
• Strong communication skills
• Excellent technical and analytical skills, as well as problem-solving abilities
• Ability to handle stressful situations and work independently

Advantages:

• Scripting experience in TypeScript, Node.js, or Rust.
• Familiarity with NATS or similar event-driven testing.
