You will play a critical role in safeguarding our devices from vulnerabilities introduced by external applications, while collaborating with global teams and driving quality and security best practices.
Responsibilities
Leading validation and certification testing of 3rd‑party applications from a platform integrity and security perspective.
Impact system stability, uptime, or reliability.
Exceed controller processing, memory, or storage resources, or violate file system constraints.
Misuse system interfaces, APIs, or communication channels.
Performing security‑focused testing, including vulnerability analysis.
Evaluating application behavior within embedded Linux environments, including:
Process isolation
File system access
Resource consumption
System calls and permissions
Validating safe interaction with controller firmware, OS, and hardware interfaces.
Conducting compatibility and integration testing with controller APIs and communication protocols, including:
REST
MQTT
CoAP
Performing network and protocol analysis using tools such as Wireshark and packet sniffers.
Testing and validating serial communication interfaces and low‑level protocols.
Monitoring runtime behavior to detect abnormal or malicious activity.
Developing and maintaining automated test frameworks and CI‑CD pipelines.
Writing scripts for test automation, monitoring, and security validation.
Defining and enforcing application acceptance criteria and certification standards.
Identifying risks introduced by untrusted or third‑party code execution.
Documenting security findings, validation results, and certification outcomes.
Collaborating with engineering, product, and external partners on secure integration practices.
Mentoring junior engineers and promoting best practices in embedded QA and security testing.
