Senior Software Engineer

Company Overview

Farel is a San Francisco-based startup revolutionizing how airlines manage inventory and sales with our cutting‑edge SaaS platform. We’ve raised over $4M from top‑tier Silicon Valley investors, including Y Combinator, and have built an online travel agency (OTA) that was acquired by a publicly traded company. Our diverse and dynamic global team spans the US, Georgia, Turkiye, Kazakhstan, Serbia, and Mexico, and we are ambitiously pushing the boundaries of the aviation industry.

We are seeking a Senior Product Engineer who cares deeply about business impact, not just technology. You will own problems end‑to‑end, work across the stack, and help shape how airlines sell and distribute their products. If you enjoy turning ambiguous business needs into simple, robust software and measurable outcomes, we’d like to talk.
