Staff Software Engineer, Developer Platform (Auth0)

Okta•Toronto, ON

7h•CA$160,000 - CA$220,000•Hybrid

About The Position

The Developer Platform team at Auth0 (an Okta company) owns the surfaces developers use to build with Auth0 - APIs, SDKs, CLIs, and the tooling that shapes how developers experience identity. Software is increasingly built by developers working alongside AI agents, and that shift raises the bar on every interface we ship: APIs have to be consumable by agents, tools have to be discoverable, and our platform has to hold up when an agent - not just a person, is the one calling it. We're looking for an engineer who already builds with those skills. We move fast, we own problems end-to-end, and we care deeply about the developer experience we put in front of people. We're hiring a Staff Software Engineer to build the platform surfaces that developers and AI agents use to configure, extend, and interact with Auth0. You'll work at the intersection of API platform design, developer tooling, and emerging standards like MCP (Model Context Protocol). You'll take on ambiguous, high-leverage problems alongside a group of strong senior and staff engineers, and you'll have real influence over how our platform is built for a world where agents are first-class consumers.

Requirements

7+ years of software engineering experience, with meaningful time on platform, SDK, or developer-tooling work
Strong Node.js fundamentals; Go a plus
A track record of designing and shipping APIs or developer-facing surfaces at scale
Comfort owning ambiguous problems without heavy top-down scoping
Experience collaborating across engineering, product, and architecture in a fast-moving environment
A bias for execution - you ship, you learn fast, and you make the people around you better

Nice To Haves

Hands-on familiarity with agentic tooling, MCP, or LLM-facing API design - a meaningful differentiator for this role
Experience with identity, authorization, or IAM platforms
Work with agent frameworks, AI-facing APIs, or developer toolchains in the LLM space
Background at a company where developers are the primary customer

Responsibilities

Design and build developer-facing platform surfaces - APIs, MCP tools, CLI integrations, that hold up whether the caller is a developer or an agent
Own technical direction for key platform surfaces that make Auth0 consumable by agents
Drive cross-cutting technical decisions that keep our platform coherent and easy to build on
Operate peer-to-peer with tech leads across teams: own your work, unblock others, and raise the execution bar
Bring developer's empathy to everything you ship - you understand how developers consume APIs and you design accordingly
