Summary

We are seeking a Senior Staff Engineer in Temporal's Cloud Global Services team to lead the technical strategy and execution of the Unified Temporal Proxy initiative. This individual will be responsible for consolidating disparate proxy implementations into a single, extensible, open-source, and productized solution. The unified proxy is not only a critical enabler for customers—providing security, encryption, and advanced integration capabilities—but also a core component of Temporal Cloud’s own infrastructure, powering hybrid-cloud scenarios and new functionality such as HTTP endpoint support and AI/agent workloads.

The role spans architecture, cross-team collaboration, customer engagement, open-source leadership, and long-term product ownership, with a mandate to build and deliver a reliable, extensible foundation that will serve both customer-facing and internal needs for years to come.

The Need for a General Proxy

The Unified Proxy will be a critical enabler for both customers and Temporal Cloud. It is a foundational component that will unlock the next phase of Temporal’s platform evolution:

• Customer Trust & Security

Customers can depend on the proxy as a secure, production-grade tool that enforces policies consistently and reduces the risk of misconfiguration across all Temporal-related activities. Key concerns addressed include payload encryption, fine-grained authorization logic, and integration with custom identity stores, among others.

• Enabling New Critical Functionality

The unified proxy introduces capabilities that are otherwise not possible, such as migrations between self-hosted clusters and Temporal Cloud without requiring complex custom setups. It will also become the preferred way to support HTTP endpoints for Temporal services, expanding accessibility and simplifying integrations.

• Foundation for the AI Era

In a future where AI agents are abundant and interact via the Temporal Nexus protocol with MCP servers, the proxy will serve as a central component to ensure secure, controlled, and seamless communication patterns.

• Core Part of Temporal Cloud Infrastructure

Beyond enabling customer adoption, the unified proxy is a pillar of Temporal Cloud’s own infrastructure, powering internal services and extending Temporal’s ability to support hybrid-cloud and enterprise-grade scenarios.

• Engage directly with strategic customers to understand and incorporate their requirements.
• Mentor other engineers on distributed systems architecture, networking, and security.
