Job Category Software Engineering Job Details About Salesforce Salesforce is the #1 AI CRM, where humans with agents drive customer success together. Here, ambition meets action. Tech meets trust. And innovation isn’t a buzzword — it’s a way of life. The world of work as we know it is changing and we're looking for Trailblazers who are passionate about bettering business and the world through AI, driving innovation, and keeping Salesforce's core values at the heart of it all. Ready to level-up your career at the company leading workforce transformation in the agentic era? You’re in the right place! Agentforce is the future of AI, and you are the future of Salesforce. The Experience Join our dynamic team at Salesforce and make a real impact with your code! We’re looking for passionate individuals who want to shape the future of our products and deliver exceptional experiences to our customers. Equally important is advanced prompt engineering — the ability to write precise, structured prompts and cultivate the system context that makes AI outputs reliable, secure, and production-ready. Come be a part of our innovative and collaborative environment, where your skills will thrive and your ideas will be valued. Apply now and let’s build something extraordinary together! We embrace the hybrid model and celebrate the individual strengths of each team member while encouraging everyone on the team to grow into the best version of themselves. We believe that autonomous teams with the freedom to make decisions will empower individuals, products, companies, and customers to thrive. About the Team: Authentication Core decides how every user, admin, and integration signs in to Salesforce. We own login flows, session management, MFA, and the OAuth 2.0 / OpenID Connect and SAML endpoints that issue and validate credentials at global scale. We also own the defenses around them: binding sessions to devices (DBSC and Web Crypto) to prevent session hijacking, rolling out mTLS, enforcing PKCE and refresh-token rotation for connected apps, and retiring legacy login protocols. A mistake here is a security incident or a global outage, so we hold a high bar for correctness, security, and operations. Your Impact: Your work protects every Salesforce customer’s front door. You’ll ship security improvements to hundreds of millions of users without breaking the integrations enterprises depend on. What You'll Actually Be Doing • Architect, design, implement, test, and deliver highly scalable authentication and session services on Salesforce Core (Java), with strict availability and latency requirements • Build and evolve standards-based identity protocols, including OAuth 2.0/2.1, OpenID Connect, SAML 2.0, and newer ones such as PKCE, DPoP, mTLS-bound tokens (RFC 8705), token exchange, and Device Bound Session Credentials (DBSC) • Harden sessions and credentials against hijacking, replay, phishing, and credential stuffing, using token binding, refresh-token rotation, secure cookie design (SameSite, CHIPS), and step-up authentication • Threat-model new features, work with Product Security, and fix findings from penetration tests, bug bounty, and incident reviews • Roll out security enforcement safely for customers using feature flags, phased cohorts, telemetry-driven decisions, backward compatibility, and clear deprecation plans for legacy endpoints • Master our development process, culture, and code base, then improve it • Operate optimally in the hybrid engineering model where engineers are encouraged to be able to craft and complete the vital work to ensure quality in their own code as well as ot
