Senior Architect, Emerging Technologies Auth0

Secure Every Identity, from AI to Human Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence. This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk.

We are looking for a Senior Architect to join our Emerging Technologies organization. This is a high-leverage, hands-on engineering role designed for a technical leader who wants to stay in the code while steering the architectural direction of our most ambitious bets.

You will be a core contributor and architectural anchor for two high-priority workstreams:

Fine-Grained Authorization (FGA) | Scaling 1 to 10

To build a world-class, low-latency FGA system that remains resilient under the industry’s most complex identity hierarchies. We are looking for an architect who views authorization not as a set of rules, but as a massive-scale graph computation problem that requires elegant, distributed, and mathematically rigorous solutions. The Work:

Algorithmic Innovation: Moving beyond naive graph algorithms to implement probabilistic structures and fixpoint algorithms capable of navigating massive organizational hierarchies without computational or memory exhaustion.

Graph Resolution Heuristics: Engineering workload-aware heuristics that can intelligently prioritize and resolve graph queries based on complexity cost, maintaining low latency even when faced with high-cardinality data sets and deep nesting.

Fixpoint & Cycle Resolution: Solving for complex resolution requirements, such as circular references and recursive paths, in a horizontally scaled environment where traditional distributed patterns fail to meet our performance mandates.

Scaling the Probabilistic Logic: Designing the engine to utilize non-deterministic approaches where exact computation is too expensive, ensuring the system remains mathematically rigorous while operating at the limits of global scale.

AI Products | 0 to 1

We are pioneering the "Agentic Identity" space. This workstream is focused on building foundational products that secure AI Agents and provide developers with the tools to manage identity in an autonomous world.

The Work: Rapidly architecting and shipping 0-to-1 product offerings that define how agents interact securely.

The Goal: Establish our platform as the standard for securing the next generation of AI-driven applications.

Core Responsibilities

Architectural Acceleration: Don’t just design it, build it . You will accelerate teams by writing critical-path code and providing the architectural "connective tissue" between
