Job description

About Netskope

Today, there's more data and users outside the enterprise than inside, causing the network perimeter as we know it to dissolve. We realized a new perimeter was needed, one that is built in the cloud and follows and protects data wherever it goes, so we started Netskope to redefine Cloud, Network and Data Security.

Since 2012, we have built the market-leading cloud security company and an award-winning culture powered by hundreds of employees spread across offices in Santa Clara, St. Louis, Bangalore, London, Paris, Melbourne, Taipei, and Tokyo. Our core values are openness, honesty, and transparency, and we purposely developed our open desk layouts and large meeting spaces to support and promote partnerships, collaboration, and teamwork. From catered lunches and office celebrations to employee recognition events and social professional groups such as the Awesome Women of Netskope (AWON), we strive to keep work fun, supportive and interactive.

About the role

Please note, this team is hiring across all levels and candidates are individually assessed and appropriately leveled based upon their skills and experience.

Join Netskope’s Cloud Data Plane team — building one of the world’s fastest, most intelligent in-line inspection engines, processing 10+ Gbps of traffic at line rate.

In this defining role, you’ll architect and build a Domain-Specific Language (DSL) and its complete compiler toolchain for our next-gen CASB Inline platform, enabling highly efficient policy and signature execution.

What’s in it for you

In this role you will be a key member of the NG-SWG team supporting our in-line CASB and SWG products, both of which have been recognized by Gartner as market leaders in their Magic Quadrant reports.

• Define the grammar, syntax, and semantics for a new security-focused DSL.
• Design and implement the full compiler pipeline – parser, AST, type checker, semantic analyzer, IR, and code generator.
• Develop advanced compiler optimizations and tune runtime performance for high-throughput, low-latency execution.
• Own the end-to-end lifecycle — from architecture and prototyping to deployment and long-term evolution.
• Mentor engineers and drive the technical roadmap for language and compiler systems across the CASB/SWG platform.
• Collaborate with product, research, and platform teams to ensure seamless integration into Netskope’s security stack.

Required Experience

• 12+ years of software development experience with 3+ years in a Staff/Principal architecture role.
• Proven expertise in compiler design, language theory, and systems programming (C++, Rust, Go, or Python).
• Strong background in parser frameworks (ANTLR, LLVM, Yacc/Bison).
• Hands‑on with runtime performance tuning, profiling, and low‑level memory management.
• Demonstrated success owning large-scale, high-performance systems from design to production.
• Excellent technical communication and leadership skills.

Preferred Qualifications

• Experience contributing to or maintaining open‑source compiler or language projects.
• Familiarity with functional programming paradigms.
• Exposure to networking and security domains — especially in traffic inspection, DLP, or signature‑based detection systems.
• Knowledge of JIT compilation or virtual machine design is a plus.
• Bachelor’s/Master’s in Computer Science, Engineering, or related field.
