Develop automation for MDM and endpoint management workflows.
Verify interoperability with native operating system services, security frameworks, and device management APIs.
Develop large-scale automated regression suites for endpoint releases.
Improve release quality through automated validation of agent stability, performance, resource utilization, and security.
Identify quality risks and proactively expand test coverage.
Troubleshoot complex defects through log analysis, debugging, telemetry, and endpoint diagnostics.
Reproduce customer-reported issues across diverse endpoint environments.
Partner with Support and Engineering teams to perform root-cause analysis.
Create automation preventing recurrence of production issues.
Utilize AI coding assistants and coding agents to generate and maintain automation assets.
Apply AI tools for test generation, code analysis, debugging, and coverage expansion.
Validate AI-generated tests and automation through engineering best practices.
