Are you a developer who actually enjoys talking to people, or a tech-adjacent professional who wants to leverage your software background for high-paying outbound roles? We are building an engineering-focused platform and need a Native American English speaker to handle technical discovery calls and schedule product demos with CTOs, VREs, and Lead Architects. Instead of reading a robotic script, you will be having peer-to-peer technical conversations to qualify leads. We are specifically looking for someone with prior development experience (React, Node.js, Python, or similar stacks). You won't be writing code in this role, but you must speak the language. Because you understand architecture bottlenecks, API integrations, and developer pain points, you can easily navigate technical gatekeepers and hold meaningful conversations with senior engineering leadership. This is a fully remote, part-time position with highly flexible hours, but calls must be made during standard U.S. business hours (EST/PST). You will need a quiet home office, a solid internet connection, and a professional headset. If you want to step away from the IDE for a few hours a day and use your dev background to drive outbound growth, apply with a quick overview of your tech stack and a brief Loom introduction.
