Ready to make an impact at the company pioneering security transformation in the AI era? Join us at Zscaler.

Role

We are looking for a Principal Software Development Engineer to join our team. This is a Hybrid role, reporting to the Director, Software Engineering in the Engineering department. You will join the team that built the world’s largest cloud security platform from the ground up, enabling organizations worldwide to harness speed and agility with a cloud-first strategy.

• Thrive in ambiguity, comfortably building the path as you walk it and viewing dynamic environments as opportunities to construct meaningful solutions.

• Operate with a strong sense of ownership, combining a passion for the mission with high integrity and the ability to navigate seamlessly between high-level strategy and hands-on execution.

• Demonstrate a proactive problem-solving focus, eagerly running toward challenges and remaining laser-focused on delivering high-impact outcomes.

• Build high-trust collaboration, prioritizing team success, welcoming constructive feedback, and practicing clear and respectful candor to establish strong partnerships.

• Maintain a continuous growth mindset, actively seeking feedback and development to grow as a partner, teammate, and purpose-driven leader.

What We’re Looking for (Minimum Qualifications)

• Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain

• Bachelor's or Master's (preferred) degree in Computer Science or a related field with 10+ years of experience in system engineering for high-performance networking

• Expertise in Linux kernel-based networking (L2/L3), stateful firewalls, NAT, network drivers, routing protocols, and tunneling technologies

• Proficiency in Go and Python programming languages with excellent problem-solving skills for debugging complex data path issues

• Strong communication and collaboration skills to work effectively with cross-functional teams in a high-accountability environment while designing scalable systems

What Will Make You Stand Out (Preferred Qualifications)

• Proven ability to leverage AI technologies and workflows to drive measurable operational efficiency

• Experience integrating AI/ML frameworks or intelligent data path analysis models to optimize kernel-level networking performance and automate predictive threat detection

• Advanced experience with networking technologies, tunneling protocols, high-availability protocols, and security certifications like FIPS or FedRAMP

• Familiarity with public cloud platforms, containerization with Docker and Kubernetes, and advanced virtualization or security solutions
