Senior Software Engineer - Build End-to-End, Full-Stack

Fonzi Match Day is where full stack engineers who actually build things meet the companies worth building for. No job boards. No recruiter spam. Companies request to interview you and submit salary bids upfront. Every week, hiring managers at 100+ pre‑vetted startups in NYC and San Francisco review a curated group of engineers. They read profiles optimized by our team to surface what matters: what you’ve built, how you think about systems, and whether you’re the kind of engineer who ships. Companies on Fonzi are building AI‑native products, scaling complex web applications, and shipping features end‑to‑end from database to UI. Backed by a16z, Sequoia, General Catalyst, Y Combinator, and more. How It Works Apply in 2 minutes. We reach out, learn what you’re building and what excites you, and optimize your profile. Hiring managers review the cohort and request interviews with candidates they want. Companies submit competing salary bids directly to you. You only interview where you’re genuinely interested. Completely free + we have an iMessage agent plus humans in the loop you can text anytime for scheduling and coordination. Who We’re Looking For Engineers who own features end‑to‑end, from API design to frontend polish. Comfortable making architectural decisions across the stack and shipping fast without sacrificing quality. Have worked in environments where you had to figure out what to build, not just how to build it. 2–8 years of experience, ideally with time at a high‑growth company. Interview Process Most Fonzi companies run a lean, respectful process: a screening conversation focused on communication and genuine curiosity, a technical deep‑dive on architecture and system design, and then a coding or pairing session. If you’re an engineer who loves building across the entire stack and wants companies competing for your attention instead of the other way around, we want to hear from you. #J-18808-Ljbffr Fonzi
