The Product

Auth0 is a developer-friendly identity platform designed by developers, for developers, simplifying authentication and authorization for more than 100 million daily logins worldwide. Within this global platform, our team drives two of Auth0’s most critical, high-impact surfaces:

• The Manage Dashboard: The definitive front door for developers and enterprise administrators worldwide. It is the control center where our customers configure critical identity policies, manage complex organizations, and monitor active threat intelligence.
• The Auth0 Marketplace: Our rapidly expanding extensibility ecosystem. The Marketplace allows customers to seamlessly discover and install third-party integrations - such as security monitoring, consent management, and database connectors - to dynamically customize their identity pipeline.

The Role

As a Staff Engineer on this team, you will not just write code; you will own the technical strategy, architect highly resilient frameworks, design developer-friendly APIs, and mentor a high-performing team of engineers. Your architectural ownership will span the entire stack - from the React-based frontend down through our Node.js/Go services, robust operational pipelines, and PostgreSQL databases.

What You Will Do:

• Product Ownership: Lead the technical lifecycle of your team’s products, ensuring they are robust, secure, and performant from the frontend to the infrastructure layer.
• Full-Stack Execution: Bridge the gap between UI and Backend by designing clean APIs, efficient data flows, and scalable service architectures.
• Architecture & Design: Create and document technical designs for team initiatives, ensuring they account for scale, reliability, and regional constraints.
• Operational Health: Ensure your team’s services meet strict performance and security standards (SLAs/SLOs), including observability, rate-limiting, and SEO.
• Mentorship: Elevate the technical bar of your team through code reviews, design feedback, and hands-on guidance.

Key Qualifications:

Technical Execution (Full Stack):

• 8 to 12 years of hands-on experience in JavaScript/Node.js/Go and React/Next.js.
• Experience in designing, building, and operating distributed systems in a cloud environment (e.g., AWS, Azure).

Backend -

• Service Design: Strong proficiency in designing and building scalable services using Node.js (mandatory) or Go.
• Cloud Infrastructure & Kubernetes: Deep, hands-on experience deploying, scaling, and operating backend services on AWS, with strong proficiency in Kubernetes for container orchestration.
• Data, Caching & Pipelines: Strong experience with relational databases (PostgreSQL), distributed caching (Redis), and data/deployment pipelines.
• Performance & Scale: Experience using quantitative analysis (latency, traffic volume) to justify your design and technology choices.
• Strong production systems experience, including monitoring, debugging, and incident response.

Frontend -

• Hands-on experience with modern React & MobX/Redux
• Build tools: Strong experience with frontend build tools, module bundlers, package managers
• Web Performance: Understanding of core web vitals, page speed and performance optimization.
• End-to-End Systems Knowledge: A clear understanding of how web traffic moves from the browser through CDNs, Load Balancers, and API Gateways to the backend.

Delivery & Quality:

• Backend Excellence: Designing highly reliable backend architectures and implementing robust, automated delivery pipelines.
• Operational Mindset: Familiarity with the "Product-Ops" side of engineering - including security best practices , telemetry, alerting, and monitoring.
• Clear Communication: Ability to articulate technical trade-offs and visualize system flows for both technical and non-technical stakeholders.

Nice To Haves:

• Experience in the Identity and Access Management (IAM) domain.
• Knowledge of security engineering principles and application security best practices.
