Senior Software Engineer, Security

ABOUT US We're living through a fundamental shift in how people discover, evaluate, and purchase products. The next generation doesn't respond to traditional marketing -- they build relationships with brands through authentic social interactions, seek recommendations from communities they trust, and expect personalized experiences that feel human, not corporate. At Nectar Social, we're building the AI-native social operating system that enables this new era of commerce. We believe every social interaction should deepen the relationship between brands and their communities while creating genuine value for both sides. Founded by ex-Meta product and engineering leaders, we've raised over $30M in total capital from investors including GV and True Ventures. We work with brands like Oura Health, Caraway, e.l.f. Cosmetics, Kosas, OLIPOP, and many more. We're building the future of social commerce -- where community, conversation, and commerce converge. THE ROLE We're looking for a Senior Software Security Engineer to own security across our enterprise SaaS platform -- from the design of our deployed applications to the compliance programs that earn the trust of large brands. We handle sensitive social and customer data at scale, and our customers expect enterprise-grade security and rigorous proof of it. As the first Security engineer, you'll have outsized ownership.
