Role
We are looking for a Principal Sales Engineer to join our team. This is a Hybrid role, reporting to the Senior Director, Sales Engineering in the APJ Field Sales department. A Principal Sales Engineer is an industry expert who advises, encourages and challenges customers and prospects to evolve their cybersecurity architecture from one based on legacy Network and Perimeter architectures to one based on Zero Trust Architecture design principles leveraging the Zscaler Zero Trust Exchange (ZTE).
What you’ll do (Role Expectations)
- Facilitate consultative discovery and design workshops meant to uncover a customer’s business requirements and their current-state architecture
- Design a high-level Zero Trust Architecture including a phased adoption roadmap expressing how the customer can transform to a Zero Trust Architecture future-state over time
- Engage across customer functional teams, as well as Zscaler partner and internal teams, to develop rapport and to ensure success across organizational structures from engineer to executive
- Code-switch seamlessly between CXO and IT Operations audiences to balance a combination of executive presence and deep technical credibility
- Adopt a confident, yet consultative customer-facing persona built on executive presence and humility
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
- 15+ years of relevant experience, or 10+ years of experience and an advanced degree
- Advanced product expertise and solution development capability, delivering on advanced solution selling across end-to-end Enterprise Architectures and complex Networking and Security environments
- Hands-on experience with technologies including TCP/IP protocol stack, DNS, BGP routing, MPLS, SD-WAN, GRE, IPsec, Layer-7 firewalls, Web Proxies, Load Balancing, and Data Loss Prevention
- Strong familiarity with NIST Zero Trust Architecture along with applicable laws, regulations, standards, and frameworks such as GxP, GDPR, HIPAA, PCI, ISO 27001, NIST CSF, MITRE ATT&CK, Cyber Kill Chain, and CISA
What Will Make You Stand Out (Preferred Qualifications)
