Job summary

Zscaler, Inc. in Santa Clara, CA, seeks a Principal Software Development Engineer (Go) to lead the transformation of the infrastructure into a durable, self-healing management plane for a global fleet.

This hands-on role focuses on building deterministic provisioning, workflow-as-code with Temporal, and scalable orchestration across the Zero Trust Exchange. You will design platforms and APIs, integrate AI/ML signals, and implement robust telemetry to ensure explainable, auditable operations at

Qualifications

• Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain.
• BS/MS in Computer Science or a related technical field with 12+ years of experience in hyperscale systems, with a deep understanding of the unique failure modes and technical hurdles that only emerge at massive scale.
• Mastery of backend systems languages with a strong preference for Go (or deep expertise in Java, C++, or Python with a demonstrated ability to rapidly adopt Go), along with a proven track record of setting the bar for code quality and distributed system correctness.
• Strong experience designing and operating complex distributed systems, with a focus on solving systemic challenges in concurrency, failure handling, and performance optimization.
• Proven track record of developing Platform APIs (REST/gRPC) with strong guarantees for idempotency, verification, and safe rollout patterns

Responsibilities

• Lead hands-on development and migration to a workflow-as-code platform (Temporal), building replay-safe, idempotent workflows for deterministic operations at global scale.
• Move the organization beyond scripted automation to a robust management plane treating the fleet as a single, eventually-consistent distributed system.
• Design and implement services that leverage LLMs and ML for intelligent signal correlation, automated triage, and self-correcting fleet operations.
• Develop framework-level services and internal APIs ensuring new products are orchestration-ready with reliability hooks built into code.
• Build deep telemetry (metrics, traces, events) into the management plane for fully explainable, auditable, and replayable fleet actions
