Staff Software Engineer, Authentication (LA Preferred) Los Angeles, CA • San Francisco, CA Security Remote Full-time

Staff Software Engineer, AuthenticationThe Role

We are looking for a Staff Software Engineer to join our Security team, with a particular focus on Authentication Engineering and Identity and Access Management. In this role, you’ll have the opportunity to build and evolve the systems that secure our users’ accounts and their interactions with Linktree. You will be responsible for designing and implementing secure and scalable authentication systems, working closely with cross-functional teams to ensure seamless user experiences across a variety of touchpoints.

What You’ll Own

• Design, Develop and Deploy Authentication Solutions: Take ownership of the design, implementation, and ongoing release of authentication solutions and integrations throughout the application, ensuring compliance with security standards and regulations, are user-friendly, and scalable.
• Token Management: Manage authentication and authorization tokens and ensure secure handling across the platform.
• Cross-functional Collaboration: Work closely with product and platform teams to design and secure APIs and the underlying infrastructure that supports our authentication protocols and frameworks, such as OAuth, OpenID Connect, SAML and Kerberos.
• Lead Platform and Backend Security: Lead efforts to secure our platform, including CI/CD pipelines, infrastructure, and tools used by development teams.
• Building from the Ground Up: You’ll have the opportunity to build authentication systems from scratch, rather than just maturing existing ones. This role offers the chance to contribute to a foundational and critical part of Linktree's infrastructure.
• Ownership of Key Systems: Your name will be on the solutions you deliver, driving both the technical execution and the vision for authentication systems at Linktree.

Who We’re Looking For

• Experience in Authentication & Identity: You have a solid background in designing and implementing authentication solutions and managing authentication tokens, federated identity, privileged access management (PAM) and SAML. You understand the nuances of securing user accounts, system accounts, environments and have a deep understanding of authentication protocols.
• Backend Software Engineer: You are a seasoned backend engineer with a strong grasp of building scalable and secure systems. Experience with our tech stack is a plus but not a requirement: Typescript, Node.js, PostGreSQL, GraphQL, AWS (S3, EventBridge, SQS, Lambda, ECS, DynamoDB, CDK), and Snowflake. Our monolith also includes a PHP code base.
• Leadership: You are capable of taking the lead on complex technical initiatives and are comfortable working with minimal mentorship. You’ll drive the design and implementation of key systems and take ownership of their success.
• Excited About Building: You’re passionate about building systems from the ground up. While the team is growing and maturing its infrastructure, this is a unique opportunity to shape foundational components from scratch.
• Payments Integration (Bonus): Experience with payments integration is a nice-to-have but not required. However, if you’ve worked with payment systems, especially in relation to authentication, that experience could be valuable.
