Software Development Engineer in Test

As a Software Development Engineer in Test tasked to join our On Prem team and help us build a high-quality, reliable self-hosted product. The ideal candidate combines strong automation depth with solid product thinking — someone who understands how customers use the product, knows where quality risks hide, and can design the right test strategy to catch them early.

What will you do

Primary responsibilities include:

• Own the quality strategy for key Cloud Security features and services across functional, integration, and end-to-end test coverage.
• Design, build, and maintain scalable automation frameworks and test infrastructure, with a strong emphasis on API and service-level validation for distributed, high-throughput systems (and UI validation where applicable).
• Build testing approaches that validate the accuracy of our detection and policy engines — guarding against false positives and false negatives in the security findings we surface to customers.
• Design and run performance, scale, and resilience tests for services that evaluate hundreds of thousands of cloud resources and objects across multiple regions and providers.
• Work closely with developers, product managers, and other QA / automation engineers to define test plans early and improve release confidence.
• Develop, execute, and continuously improve automated test suites for new and existing functionality, while analyzing failures, reporting issues clearly, and driving resolution with engineering.
• Own validation from feature design through release, including test planning, execution, triage, and sign-off.
• Raise the bar on product quality by identifying gaps in testability, observability, reliability, and release readiness.
• Extend quality coverage into Cloud and On-Prem Data Storage Protection, validating data discovery, classification, and exposure detection across cloud object stores, managed databases, and on-prem file systems and storage repositories.
• Drive better quality processes, dashboards, reporting, and CI signals for faster and safer releases.

What skills and experience should you bring

Ideal candidates will have:

• 5+ years of experience in test automation / automation development.
• Strong product thinking with the ability to translate product behavior and customer workflows into effective test strategy
• Strong hands-on experience with Selenium, Playwright, Python, and TypeScript
• Strong experience building robust test automation for complex systems, aligned with the current JD’s focus on complex system-level testing.
• Experience debugging issues deeply and working closely with developers to drive fixes.
• Strong experience with Jenkins-based CI pipelines and test execution workflows
• Experience with Allure or similar test reporting / insights platforms
• Solid understanding of automation architecture, test design, and maintainable framework development
• Strong problem-solving, ownership, and self-management skills; proactive, collaborative, and able to operate with high independence.

Bonus

• Experience in cybersecurity products or security testing
• Experience working with coding agents / AI-assisted development workflows
• Meaningful open source contributions
• Experience testing self-hosted, enterprise, or infrastructure-heavy products
• Familiarity with release validation in environments with customer-specific deployments
