Senior Software Development Engineer in Test , Bangalore based role - Hybrid.

Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.

What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Senior Software Development Engineer in Test tasked to join our 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 Kubernetes objects across multiple regions.
• 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.
• Help extend quality coverage into Cloud AI Security as our CNAPP capabilities expand to secure customers' AI workloads and infrastructure.
• Drive better quality processes, dashboards, reporting, and CI signals for faster and safer releases.
• Mentor other engineers on automation best practices, debugging, and quality engineering principles.

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 building API and service-level test automation for complex, distributed systems and microservices.
• Strong proficiency in Python and TypeScript; experience with Go is a plus.
• Hands-on experience with UI automation tools such as Selenium and Playwright where UI coverage is needed.
• Experience testing services that run on at least one public cloud (AWS, GCP, or Azure) and on Kubernetes (Docker).
• 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.
• Interest in performance and scale testing; you enjoy validating systems for correctness and efficiency under load.
• Strong problem-solving, ownership, and self-management skills; proactive, collaborative, and able to operate with high independence.
