• Drive quality engineering strategy across features and releases.
• Influence system architecture to improve testability, reliability, and observability.
• Mentor engineers and elevate QE practices across the organization.
• Lead cross-team defect triage, root cause analysis, and quality improvement initiatives.
• Define metrics, dashboards, and KPIs for product quality.
• Design, develop, maintain, and execute test cases and test plans at functional and system levels.
• Perform black-box and gray-box testing of released products and products under development to reveal design and implementation defects.
• Understand the focus of functional, system, integration, and regression testing at feature and system levels.
• Use test tools such as debuggers, emulators, and simulators to complement testing.
• Use bug tracking systems to track the life cycle of bugs.
• Develop and maintain quality engineering processes and initiatives.
• Identify automation opportunities and develop and maintain automated tests.
• Analyze test results, troubleshoot, and triage issues across teams to perform root cause analysis and resolution.
• Collaborate with developers, product managers & QA engineers to complete assigned tasks.
• Evangelize software testing best practices and influence architecture.
• Define and execute non-functional testing strategies, including performance, scalability, reliability, and resilience testing.
• Validate system behavior under stress, fault injection, and recovery scenarios.
• Evaluate system power consumption, resource usage, and platform efficiency for embedded Linux environments.

Customer Driven:

• Thinks/acts with the customer in mind. Committed to quality customer service with a consistent, positive, can-do attitude to both internal and external customers.

Lean:

• Uses lean thinking and problem-solving techniques to identify and eliminate root problems. Continually looks for ways to eliminate waste and makes suggestions for improvement.
• Supports safety programs and keeps the workplace clean and safe. Avoids shortcuts that increase the risk of accidents, personal injuries, and equipment failures. Makes recommendations when appropriate.

Quality of Work:

• Has established a track record of producing highly accurate work, demonstrates attention to detail, and reflects well on the organization.
• Is personally committed to high-quality work and encourages others to have similar standards.

Decision Making/Judgment:

• Recognizes problems and responds. Systematically gathers information, sorts through complex issues, seeks input from others, addresses the root cause of issues, and makes timely decisions.
• Can make difficult decisions, using consensus when possible. Communicates decisions to others.

Managing Priorities/Dependability:

• Gives appropriate priorities to various work demands and manages time and workload effectively.
• Readily accepts new responsibilities while fulfilling all commitments. Stays focused under pressure and adapts with flexibility to changing business needs.

• Demonstrates good listening skills and seeks to understand the perspective of others.

Teamwork:

• Works collaboratively with others throughout the organization to achieve results.
• Builds relationships, establishing mutual trust/respect with peers and management. Values each person's contribution to the team.

Requirements:

• Bachelor's/Master's degree in computer science, electrical engineering, or related fields.
• 7+ years of experience in quality assurance/engineering, preferably in embedded systems, IoT, or audio technologies.
• Experience with services and protocol testing, working with HTTP/JSON/REST APIs.
• Experience with Linux-based systems and wireless technologies (Wi-Fi, Bluetooth, and audio codecs).
• Hands-on experience designing and coding automated tests in scripting languages like Python.
• Hands-on experience in developing test automation with frameworks such as Playwright and Postman.
• Experience working closely with development teams in an Agile software development environment.
• Experience with project, test, and knowledge management tools such as Jira, Xray, and Confluence.
• Excellent oral and written communication skills.
• Excellent analytical, problem-solving, planning, and organizing skills.
• Experience with non-functional testing tools (performance, load, and chaos testing).
• Experience with CI/CD pipelines and quality gates.
• Experience with observability tools (logs, metrics, tracing).
• Familiarity with IoT protocols (e. g., MQTT, RTP, SIP) (optional but valuable).
• Experience applying AI tools in software development or testing workflows.
• Proven ability to lead cross-functional initiatives without direct authority.
