Your role

• Build the Social Graph: Design and implement scalable systems for our follow graph, enabling rich connections and powering people recommendations across Handshake.
• Deliver Personalized Experiences: Integrate LLM/AI and machine learning into our profile, people search, and feed experiences—ensuring every user receives relevant recommendations and content.
• Power the Feed: Own and evolve the backend for our social and content feeds, working cross-functionally with Staff Engineers and product teams to ensure the feed both reflects and shapes the user’s network and interests.
• Cross-Cutting Influence: Collaborate across teams to understand how user activity (e.g., likes, follows, feed engagement) influences recommendations and feed ranking, and vice versa—closing the loop between network growth and content discovery.
• Backend Leadership: Drive the design, implementation, and scaling of backend services and APIs that support people search, recommendations, and feed personalization at massive scale.
  

• 8+ years of backend software engineering experience, ideally working on social, community, or graph-based products; full stack development experience is a strong plus.
• Proven expertise with distributed systems, data modeling for social graphs, and building scalable APIs.
• Experience with machine learning or personalization systems, especially in the context of recommendations or feeds.
• Track record of collaborating with cross-functional partners (product, design, ML, and other engineering teams) to deliver impactful user-facing features.
• Experience designing and building large-scale search, social graph, or entity tagging (ET) systems.
  

• Deep experience with people search, profile systems, or social graph infrastructure.
• Familiarity with LLM/AI integration into user-facing features.
• Experience designing or scaling recommendation engines or ranking systems.
• Understanding of how user interactions (likes, follows, shares) influence feed and recommendation algorithms.
• Prior experience in social, or high-scale consumer platforms.
• Contributions to open-source graph or ML frameworks.
