Software Engineer - AI Agents

Assembled is building software to transform and elevate customer support teams, which often represent 20-50% of the people at a company. Our workforce management platform helps some of the fastest-growing, most innovative companies in the world-including Stripe, Etsy, and Robinhood-to schedule, forecast, and organize their support teams. We've raised $70m in funding from the likes of NEA, Emergence Capital, and Stripe itself. You'll be joining a special group of people who learned the ropes at companies like Stripe, Google, Atlassian, Twitter, Airbnb, Looker, NEA, Bain, and more. The Team There's a ton of work support agents handle that they don't particularly enjoy - things like managing upset customers, sorting and tagging emails, or having to say no because of policy limits. Thanks to recent technological advancements, it's now possible to automate a lot of these tasks, letting agents focus on work they're better at and actually enjoy. Our Assist Team is a small, forward-thinking group, operating like a "startup within a startup" led by our CTO, John Wang. The team is building an AI-based product that boosts the efficiency of support teams. With agentic workflows, we create AI-driven responses to support inquiries, helping agents send faster and more accurate replies, or even automatically handling responses when confidence is high.
