Role

We are looking for a Staff Software Development Engineer to join our ZIA Cloud team. This is a hybrid role based in Bangalore, India, reporting to the Senior Manager, Software Development Engineering. You will be responsible for ensuring ZIA software runs seamlessly in Public Cloud Infrastructure. You will leverage your deep expertise in network security and public cloud environments to drive hands-on development and provide technical leadership across our global platforms.

What you’ll do (Role Expectations)

  • Driving the modernization of core platforms from design to deployment, transforming complex, synchronized systems into adaptable, loosely coupled cloud architectures
  • Designing and shepherding resilient data pathways and intelligent, multi-variable routing solutions to ensure high availability for global clients
  • Defining and executing the technical roadmap for core defense systems by building foundational frameworks for next-generation cloud security postures
  • Partnering cross-functionally to tackle complex challenges and optimize deployments within modern, scalable public cloud environments
  • Fostering a culture of engineering excellence and mentoring engineers through hands-on prototyping, rigorous code reviews, and technical leadership

Who You Are (Success Profile)

  • You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
  • You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
  • You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.
  • You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
  • You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

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
  • Mastery of TCP/IP, DNS, HTTPS, VPN technologies (IPSec, SSL VPN), NAT, and load balancing alongside proven experience extending FW/SWG solutions to native cloud services
  • 6+ years of hands-on expertise in C/C++ programming for systems engineering
  • Extensive experience architecting, developing, and troubleshooting within Unix/Linux environments
  • Strong experience in core networking or cloud security infrastructure

What Will Make You Stand Out (Preferred Qualifications)

  • Experience integrating AI/ML frameworks or intelligent telemetry models to optimize cloud data path performance and automate network anomaly detection
  • Proficiency with Terraform, AWS CloudFormation, or GCP Deployment Manager for provisioning and managing public cloud infrastructure
  • Deep knowledge of BSD/Linux operating systems, kernel bypass techniques such as DPDK, and designing high-throughput, low-latency network security products
