Tenable is looking for a Staff Software Engineer to join Tenables Engineering organization to support our mission of efficiently delivering high quality solutions to our customers security challenges. You will need deep expertise in building and leading performance engineering strategies in cloud-based environments. You will drive performance test planning execution automation and analysis to ensure our systems scale perform and remain reliable under load. As a Staff Engineer youll act as a key driver of quality across multiple scrum teams and initiatives. Youll work on evolving scalable and reusable test framework along with defining performance strategy track SLO develop baseline metrics and influence engineering-wide quality standards and processes.

Your Opportunity:

Technical Leadership

• Lead the design and implementation of performance load stress scalability and reliability tests for cloud-native applications.

• Design and evolve scalable reusable test automation frameworks (UI API integration and performance).

• Define and monitor key performance indicators (KPIs) such as response time throughput resource usage and scalability metrics.

• Define performance benchmarks SLAs and KPIs for cloud-native applications.

• Collaborate closely with development DevOps and product teams to identify bottlenecks and optimize performance.

• Create a framework and implement performance test strategy including baseline benchmarks code and architectural improvements future proofing design decisions for scalable performance optimization (including but not limited to cost optimization and throughput monitoring/alerting).

• Mentor junior engineers and contribute to performance engineering best practices.

• Define the performance strategy for distributed systems generate baseline metrics and track SLOs.

• Guide adoption of shift-left testing CI/CD test integration and service-level quality monitoring.

Hands-on Engineering

• Develop and maintain automated test suites in Java Python Shell and Groovy.

• Participate in new feature architectural reviews for code optimization additional benchmarks and corner cases which would require monitoring and alerting for production bottlenecks and code optimization.

• Build in-house tools to support test data management environment simulation and reliability.

• Perform code reviews debug the automation pipeline failures pair programming and mentor other engineers.

• Monitor SLOs for feature releases MTTR for performance improvements threshold alerting and scalable production quality code.

• Strong analytical and debugging skills with the ability to interpret large volumes of test data.

Strategy & Vision

• Collaborate with Product Dev and SRE to embed quality early in the SDLC.

• Champion customer-centric quality ensuring that product reliability and usability meet real-world needs.
