Director, Performance Engineering and Test Automation

Your Role

The Stellarus Technology team builds and operates the platform, services, and products that support payer operations, member experiences, customer integrations, and internal product delivery. The Director, Performance Engineering and Test Automation will report to the VP, Engineering. In this role, you will create the automated performance and reliability validation systems that give engineering teams clear evidence before services reach production.

You will own the strategy and implementation for performance testing, load testing, scalability validation, resilience testing, synthetic monitoring, test data automation, and release gates across the Stellarus platform. You will work directly with developers to define the standards, patterns, tooling, and expectations teams use when they design, build, test, and operate services, including where AI and AI-assisted engineering tools can improve quality, speed, and signal.

This is a new role for a builder who can define the practice, implement the tooling, partner with engineering teams, and create a culture where performance and reliability are validated continuously. The role combines performance engineering, platform quality, automation, observability, and production readiness.

Our leadership model is about developing great leaders at all levels and creating opportunities for our people to grow personally, professionally, and financially. We are looking for leaders energized by creative and critical thinking, building and sustaining high-performing teams, getting results the right way, and fostering continuous learning.
