About The Position

Avante is an AI-native benefits intelligence platform built to turn benefits complexity into clarity. For employees, our agent Carly provides personalized, always-on benefits guidance. For benefits leaders, our agent Ava monitors their entire program, surfaces what needs attention, and delivers strategic intelligence on costs, utilization, and outcomes in seconds. Together, these agents create a closed-loop system where employee engagement data informs benefits strategy, and smarter strategy improves the employee experience. We're based in Seattle and work 4 days a week in the office (one day remote). We're growing fast, serving enterprise customers like Samsung, Zscaler, and News Corp. We're hiring our first Field Marketing Manager to own how we show up in market: at trade shows, in regional dinners, alongside our channel partners, and at the executive gatherings where our buyers actually make decisions. The Role We’re looking for a Senior Software Engineer who thrives in a hands-on role. You’ll be writing a lot of production code across our TypeScript-based stack while also contributing through thoughtful design, code reviews, and mentoring. This is not an ivory tower role - we need someone who enjoys solving problems at the keyboard, shipping features, and making pragmatic technical decisions. You’ll bring the judgment and maturity to guide others, but you’ll do so while actively building alongside them.
