About the role:

We are seeking a Senior QA/Test Engineer with deep experience in testing across complex, multi-layered IoT environments, including firmware, embedded systems, and edge computing. In this role, you will lead the design and implementation of robust test strategies, frameworks, and templates to ensure end-to-end quality in a dynamic and evolving product landscape.

This is a critical position for a quality-driven engineer who can operate strategically and tactically, ensuring reliable integration of software, firmware, and hardware particularly in systems involving Bluetooth connectivity, edge devices, and possibly hospital or healthcare environments.

The ideal candidate has proven experience managing high-pressure and fast-turnaround projects, delivering quality outcomes within tight deadlines. Strong expertise in IoT fixture test documentation is essential to support rigorous validation and traceability requirements.

Key Responsibilities:

• Develop and implement end-to-end test strategies, plans, and reusable templates for IoT and embedded system projects.
• Lead QA efforts across firmware, embedded systems, software applications, and cloud integration.
• Design and execute manual and automated test cases for system-level validation, including hardware-in-the-loop testing.
• Collaborate closely with firmware and hardware engineering teams to validate device functionality, communication protocols, and edge computing capabilities.
• Identify and mitigate risks early by ensuring comprehensive test coverage in uncertain, fast-changing environments.
• Define and monitor QA metrics and drive continuous improvement across test cycles.
• Create and maintain traceable documentation from requirements through to verification and validation results, with strong focus on IoT fixture test documentation to ensure clarity and reproducibility.
• Drive defect triage, root cause analysis, and feedback loops into development and test strategies.
• Contribute to the creation of test automation frameworks and test harnesses, particularly for firmware and low-level integrations.
• Manage QA deliverables effectively under high-pressure and tight turnaround schedules to meet project milestones without compromising quality.

Required Qualifications:

• 5+ years of QA/testing experience, including hands-on testing of firmware and embedded systems.
• Proven track record working in IoT environments, testing across firmware, hardware, and software stacks.
• Strong understanding of test methodologies: system, integration, regression, exploratory, and performance testing.
• Experience creating test templates, reusable assets, and scalable test plans from scratch.
• Solid understanding of firmware development life cycle, debugging, and validation techniques.
• Demonstrated experience working successfully on high-pressure projects with rapid turnaround demands.
• Expertise in IoT fixture test documentation to support detailed test execution and traceability.
• Familiarity with communication protocols such as Bluetooth/BLE, UART, SPI, I2C, etc.
• Comfortable operating in fluid, fast-paced environments with evolving requirements and priorities.
• Strong communication skills and ability to work cross-functionally with development, hardware, and QA teams.

Nice to Have:

• Experience in edge computing deployments and real-time device management.
• Knowledge of healthcare systems, hospital IT environments, or medical device testing.
• Understanding of regulatory compliance frameworks (e.g., FDA, ISO 13485, IEC 62304, ISO
• Familiarity with test tools such as TestRail, Zephyr, and automation tools (e.g., Robot Framework, Pytest, Postman).
• Scripting experience in Python, Bash, or other scripting languages for automation and data validation.
• Exposure to continuous integration pipelines (e.g., Jenkins, GitLab CI/CD) and hardware test farms.
• Scripting ability in Python, Shell, or similar for automation and test setup.
