Staff Software Engineer, Go (Service Platform & Orchestration)

About the Position

We are looking for a Staff Software Engineer (Service Platform & Orchestration) to join our team. This is a Hybrid (3 days in office) role, reporting to the VP, Engineering in the Zero Trust Exchange department. In this high-ownership position, you will engineer the management plane and reliability systems that govern ZIA’s fleet lifecycle at massive scale.

This is a hands-on building role where you will lead the transformation of our infrastructure from legacy automation into a stateful, durable management plane (built on Temporal) to achieve deterministic "one-touch" provisioning and lifecycle operations. You will treat "infrastructure as a distributed system," developing self-healing capabilities and AI-driven SRE practices for a global fleet of 100k+ instances.

Responsibilities

• Lead the hands-on development and migration to a workflow-as-code platform (Temporal), building replay-safe, idempotent workflows that ensure deterministic operations across a global scale
• Move the organization beyond "scripted automation" toward a robust management plane that treats the entire global 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 that ensure all new products are delivered "orchestration-ready" with reliability hooks built directly into the code
• Build deep telemetry (metrics, traces, and events) into the management plane so that every fleet-wide action is fully explainable, auditable, and replayable

Requirements

• 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 5+ 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
• U.S. citizenship due to the nature of the customers assigned to this role

Nice to Have

• Proficiency with AI code-assistance tools (e.g., Cursor, Windsurf) to accelerate legacy refactoring and system development
• Proficiency in PostgreSQL, or other relational stores used for high-scale, stateful management-plane services
• Direct experience building or operating systems with Temporal.io, Cadence, or similar workflow engines

We Offer

• Competitive base salary range: $152,000 - $190,000 USD
• Comprehensive benefits program including various health plans, time off plans, parental leave options, retirement options, education reimbursement, and in-office perks
• Opportunity to work in a dynamic, inclusive, and innovative environment
