Staff Software Engineer

ABOUT NECTAR 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, 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. Our AI agents listen in real time, surface actionable insights, attribute engagement to revenue, and turn conversations into conversions. Founded by ex-Meta product and engineering leaders, we work with brands like OLIPOP, Hatch, K18, Little Spoon, and many more. We hit product-market fit last year and are on a fast growth trajectory – the business has grown 10x in the past year, and we're hiring to keep up with customer demand. The Role We're looking for a Staff Software Engineer to build and scale Nectar’s core product experiences and platform.
