About the Job

This is not a traditional QA role — as a Senior SDET at Keeper, you will function as a software engineer dedicated to testability, automation, and performance validation. You will design and implement advanced automation frameworks, build custom test tools, and directly influence the architecture and quality of the KCM platform. This role requires expertise across multiple programming languages, cloud-native systems, and security-driven environments.

Responsibilities

• Architect, design, and maintain advanced automation frameworks using Playwright (TypeScript), Pytest (Python), and additional languages (Java, C#, Go)
• Develop custom test tools and harnesses to validate complex KCM workflows, APIs, and integrations
• Build and scale automation pipelines that validate performance, scalability, and security of enterprise-grade applications
• Establish and implement the foundation for security and penetration-oriented testing
• Create new modules for API testing and automation from scratch
• Integrate automated tests into CI/CD pipelines (GitHub Actions or similar)
• Develop and manage containerized test environments with Docker and Kubernetes
• Design and execute performance/load testing using k6, JMeter, or equivalent frameworks
• Implement secure login and access workflows, including SSO (OAuth, SAML) and identity provider integrations
• Execute remote access testing via VNC, SSH, and RDP across different protocols
• Conduct cross-browser and cross-platform validation with Playwright
• Monitor, analyze, and report test results using AWS-native tools (CloudWatch, S3, Lambda)
• Collaborate closely with product development to embed testability into architecture from the ground up
• Mentor and guide other QA engineers, raising the technical bar for automation practices across the team
  

• 6+ years of professional experience in QA automation and/or software engineering with a test focus

• Strong programming expertise in multiple languages (Python, JavaScript/TypeScript, Java, C#, Go)
• Proven ability to design and implement custom automation frameworks and developer tools
• Advanced experience with Playwright (TypeScript) and Pytest (Python)
• Proficiency in AWS services (EC2, S3, Lambda, CloudWatch) and cloud-native architectures
• Deep knowledge of Docker and Kubernetes for distributed and containerized testing environments
• Experience with CI/CD pipelines (GitHub Actions, Jenkins, or similar)
• Familiarity with secure authentication (OAuth, SAML, SSO)
• Background in performance and load testing methodologies
• Hands-on experience with remote access protocols (SSH, RDP, VNC)
• Excellent communication and collaboration skills, with the ability to act as a technical leader within the QA function

Preferred Qualifications

• Experience testing privileged access management, identity security, or related cybersecurity products
• Contributions to open-source testing tools or frameworks
• Familiarity with infrastructure-as-code (Terraform, CloudFormation) or cloud test automation frameworks

• Medical, Dental & Vision (inclusive of domestic partnerships)
• Employer Paid Life Insurance & Employee/Spouse/Child Supplemental life
• Voluntary Short/Long Term Disability Insurance
• 401K (Roth/Traditional)
• A generous PTO plan that celebrates your commitment and seniority (including paid Bereavement/Jury Duty, etc)
