Your Role

We’re looking for a detail-oriented and technically strong Software Engineer in Test with a passion for quality and a knack for understanding complex systems. You’ll bring a critical eye to the Tenable Security Center, Nessus and Agent products, operating in dynamic environments and identifying quality issues before they reach our customers.

We need someone with strong analytical skills, who learns new technologies quickly and thrives in a fast-moving, startup-style environment. This isn't a role for someone who waits for directions — we're looking for a self-starter, a driver, and a champion of test-driven development (TDD) principles and with strong Python and UI automation skillset. While you’ll focus on automating existing functionality, your contributions will be instrumental in maturing our test frameworks and development processes — often with limited documentation or hand-holding.

Your Opportunity

• Own and execute manual, regression, and API-level, UI tests for enterprise-grade, Onprem or cloud-based, distributed systems.
• Design, write, and maintain automated test suites that validate key functionality and prevent regressions.
• Collaborate closely with developers and product teams to ensure features meet high standards of reliability and performance.
• Identify, document, and track bugs through resolution using established QA tools like Python, Selenium, Playwright and processes.
• Contribute to the creation and maintenance of quality gates, test plans, and release readiness criteria. (including Jira Test Plans, Executions, Test Sets etc.,)
• Work hands-on in environments such as VMWare Vsphere for Virtual Machines, understanding infrastructure-level configurations that impact the application.
• Provide continuous feedback on quality, coverage gaps, and process improvements.
  
  

What You’ll Need

• 3-4 years of experience in software testing
• Demonstrated experience working with Onprem and SaaS based products.
• Deep understanding of QA methodologies, test processes, and defect lifecycle management tools.
• Hands-on expertise with manual and automated testing strategies.
• Expertise on Python with pytest framework and UI automation using Selenium or similar
• Strong technical knowledge in areas like Operating Systems, Networking, IT infrastructure, and Databases
• Familiarity with API testing tools like Postman, REST Assured, or similar.
• Ability to operate with limited product specs and still deliver high-impact results.
  
  

And Ideally

• Proficiency in one or more programming languages (Python preferred)
• Experience working in security-focused environments.
• Prior exposure to containerized environments, Kubernetes, and CI/CD pipelines.
• Familiarity with TDD/BDD approaches and the confidence to evangelize and implement them.
• Exposure to test frameworks like Selenium or Cypress or Playwright, but open to rolling up the sleeves and working on any frameworks
• Comfort working across time zones and independently managing priorities.
• Traceability Matrix, 5 why analysis of escape defects and close loop
  
  

Bonus Traits

• You are proactive and self-sufficient — you don’t need a spec to get started.
• You ask the right questions, dig into product behavior and take pride in being the user’s advocate.
• You’re comfortable in ambiguity and see it as an opportunity to lead rather than a blocker.
• You thrive in high-trust, low-ego teams and enjoy building systems that scale.
