Job Description
Your Career
From product inception to customer delivery, the Principal Software Engineer (Network Security – QA) will play a pivotal role in developing cutting-edge platforms designed to outpace our competitors and delight our customers.
As an experienced test engineer, you will apply your skills to define test methodologies and execute comprehensive test plans for our hardware and software firewall products. Your contributions will help ensure we deliver high-quality, reliable solutions to our customers.
Leveraging various test equipment and Linux-based open-source tools—alongside your knowledge of CPUs, FPGAs, ASICs, and networking protocols up to Layer 7—you will strengthen our testing practices and validate the stability and functionality of our solutions throughout development. From hands-on manual testing to automation with Python, you’ll explore and implement innovative techniques to enhance the efficiency and effectiveness of our QA processes.
Beyond technical excellence, strong communication and collaboration skills are essential, as you’ll engage with Product Line Managers, Program Managers, Engineers, and cross-functional teams across the organization.
This role is ideal for detail-oriented professionals who thrive on solving both complex and routine challenges—independently and collaboratively—in the pursuit of quality, speed, and innovation.
A forward-thinking mindset and the ability to adapt and integrate in-house AI tools to drive improved outcomes will set you up for long-term success in this role.
Your Impact
Collaborate within a small, fast-paced, and highly focused team to solve critical customer challenges and deliver high-impact outcomes.
Partner with cross-functional development and QA teams to ensure the highest quality across software and hardware platforms.
Provide technical feedback by reviewing Product Requirement Documents, Functional Specifications, and test strategies to influence product development and ensure alignment with quality standards.
Develop and execute comprehensive test plans and methodologies that validate functionality across layers—from individual components to full-stack network layers (L2–L4)
Design and implement Python-based automation frameworks, tools, and scripts to improve regression test coverage, execution efficiency, and platform validation.
Build and maintain automation infrastructure and testbeds to support scalable, repeatable testing.
Foster a culture of excellence and best practices through collaboration, ownership, and continuous improvement across teams and disciplines.
