Full-Time, Exempt
Location: Scottsdale, AZ
Salary: Competitive salary Options
As a Product Development Engineer, you will independently design, implement, and tune threat detections that support both internal SOC operations and customer-facing security outcomes. You are expected to bring a solid understanding of cybersecurity concepts and apply them to solve practical detection challenges at scale.
In this role, you will handle a wide range of troubleshooting scenarios raised by internal stakeholders—including DevOps, the SOC, and TAMs—and determine root causes across systems, escalating when appropriate. You will contribute directly to the global tuning of detection logic by identifying patterns that affect detection quality and performance across customer environments.
You will also collaborate on cross-functional initiatives to improve detection reliability, performance, and quality, ensuring that what is deployed aligns with SOC workflows and customer impact expectations. Your growing judgment, autonomy, and problem-solving capabilities are critical to the success of the broader Product Development function.
As part of your responsibilities, you will validate new product functionality and detections against defined requirements and service criteria.
