Software QA / Test Automation Engineer

We are seeking a highly skilled Software QA / Test Automation Engineer to validate our next-generation connected vehicle ecosystem. In this role, your primary scope will span mobile-to-cloud and cloud-to-vehicle environments. You will design and execute test strategies at both the component level and end-to-end (E2E), ensuring the seamless flow of data across mobile apps, cloud services, vehicle middleware, and hardware interfaces.

The ideal candidate possesses a strong white-box testing mindset, deep experience with Python-based API automation, and hands-on familiarity with IoT/automotive messaging protocols like MQTT and Protobufs (protos). Key Responsibilities

  • End-to-End & Component Validation: Design, develop, and execute comprehensive test strategies for RESTful APIs, cloud microservices, and vehicle interfaces. Validate end-to-end data flows from mobile applications, through backend cloud services, down to vehicle hardware.
  • Protocol & Messaging Testing: Validate high-frequency, low-latency data transport, serialization, and messaging layers, specifically working with MQTT brokers and Protobuf (protos) payloads.
  • Middleware & VHAL Integration: Test and verify internal vehicle middleware services, signal translations, and the Vehicle Hardware Abstraction Layer (VHAL) to ensure seamless hardware/software interaction.
  • Test Automation Development: Design, scale, and maintain robust test automation frameworks using Python(e.g., PyTest, Requests) to maximize test coverage and reduce manual regression efforts.
  • Deep-Dive Troubleshooting: Perform root-cause analysis of complex, distributed system failures. Utilize system logs, network traces, metrics, and debugging tools to isolate issues across cloud services, networks, and vehicle ECUs.
  • CI/CD & Continuous Testing: Integrate automated test suites into CI/CD pipelines (e.g., GitHub Actions, Jenkins) to support continuous validation of cloud and embedded software releases.
  • Robustness & Edge-Case Testing: Analyze system behavior and data integrity across platform upgrades, network transitions, power cycles, and complex state changes.

Required Skills & Experience

  • Connected Ecosystems: Proven experience validating complex, distributed "system-of-systems" products, with a specific focus on mobile-to-cloud and cloud-to-vehicle communication flows.
  • Testing Granularity: Deep understanding of how to perform both isolated component-level testing (mocking dependencies where necessary) and integrated end-to-end (E2E) testing.
  • Protocols & Serialization: Hands-on experience working with MQTT messaging and Protobufs (protos)serialization formats.
  • Middleware & VHAL: Experience validating vehicle middleware, signal routing, and hardware/software abstraction layers (VHAL).
  • Python Automation: Strong programming skills in Python with practical experience building automation frameworks for API, backend, and data validation.
  • White-Box Testing Mindset: Ability to analyze system architecture, internal data flows, and code dependencies to design highly targeted, risk-based test plans.
  • Technical Debugging: Excellent triaging skills with the ability to produce actionable defect reports containing precise reproduction steps, logs, traces, and payload analyses.
  • Environment Experience: Strong familiarity with Linux environments, command-line tools, system services, and basic networking configurations.
