About The Position

At LinkedIn, our approach to flexible work is centered on trust and optimized for culture, connection, clarity, and the evolving needs of our business. The work location of this role is hybrid, meaning it will be performed both from home and from a LinkedIn office on select days, as determined by the business needs of the team. Our vision is to ensure that every human and resource at LinkedIn is provided a non-repudiable identity that is used for secure communication, every access to data at LinkedIn is safe and all secret material is cryptographically protected. Our mission is to make this security infrastructure intuitive, performant, and secure. We build highly reliable and scalable services and developer-friendly infrastructure that enable engineering teams across the company to create and integrate secure features and proactively protect our members’ data. The Identity Development (IDD) team builds the identity services and developer tools that help keep LinkedIn’s people, systems, and data secure. We make secure identity and access capabilities usable across LinkedIn’s engineering ecosystem—from single sign-on and authentication tooling to host access and directory services. Our work includes services and libraries that support SSO, certificate-based host access, and identity and directory lookups. These capabilities serve internal engineering teams and operate at LinkedIn scale, where reliability, security, and a thoughtful developer experience are essential. You’ll join a collaborative team working across security, infrastructure, and product engineering to make secure access the straightforward path. Role overview As a Senior Software Engineer, you will design, build, and operate identity platforms and tools used by engineering teams across LinkedIn. You’ll take ownership of significant projects from problem definition through production, make sound technical decisions, and partner with teams across the company to deliver secure, reliable, and intuitive solutions. You’ll also help raise the technical bar through design and code reviews, operational excellence, and mentorship.
