Software Development Engineer II - Identity Authentication Services

About the role

As a Software Development Engineer II on the Identity Authentication Services team, you will help build and evolve scalable features while maintaining the exceptional availability, reliability, and low latency expected of a high‑traffic authentication platform. You will design, develop, and maintain authentication and authorization services that are reliable, secure, and performant for large‑scale customer and partner‑facing applications.

Responsibilities

• Design, develop, and maintain authentication and authorization services that are reliable, secure, and performant for large‑scale customer and partner‑facing applications.
• Implement APIs, data models, and low‑level designs that support identity, session management, and policy enforcement workflows across multiple products and platforms.
• Collaborate with product, security, and engineering teams to translate authentication and access control requirements into technical solutions and deliver features end‑to‑end.
• Own the quality, observability, and support for the services you build, including automated testing, monitoring, logging, and on‑call participation for production systems.
• Apply secure coding practices, threat‑aware design, and familiarity with AI‑driven systems, tools, or workflows, and apply AI/ML concepts to real‑world products to continually strengthen authentication capabilities.
• Contribute to technical documentation, code reviews, and knowledge sharing to enable fungibility across services and domains related to identity and access management.

Minimum Qualifications

• Bachelor’s degree in Computer Science or a related technical field; or equivalent related professional experience.
• 2+ years of relevant professional experience.
• Professional software development experience working on backend or distributed services, including ownership of at least one production service or component.
• Proficiency in at least one modern programming language and experience with service‑oriented architecture, including API design, data modeling, and low‑level system design.
• Experience building, integrating, or maintaining authentication, authorization, or identity‑related capabilities such as login, tokens, or session management in a production environment.

Preferred Qualifications

• Experience designing and operating highly available authentication or identity services at scale, including performance optimization, caching strategies, and resiliency patterns.
• Hands‑on experience with modern identity and access management standards or systems (e.g., OAuth, OpenID Connect, SAML) and their integration into large applications.
• Demonstrated ability to drive improvements in service reliability, security, and observability, including use of metrics, logs, and traces to make data‑driven decisions.
• Safely integrates and operates AI/ML‑enabled solutions that improve outcomes, such as enhancing fraud detection, risk‑based authentication, or anomaly detection in sign‑in flows.
• Experience applying AI‑assisted development or analysis tools (e.g., code generation, static analysis, traffic anomaly detection) to improve the quality and security of authentication services, including opportunities to incorporate AI into developer workflows.
