Senior Software Engineer, Legends (Remote) - $150,000/year USD - #2198945

Tired of being just another cog in the feature factory? Ready to architect, own, and build something that matters? This is your chance to break free.

Step into a role where you don't just write code—you shape the entire technical landscape.

At Legends, you'll spearhead the engineering of our D2C application that's revolutionizing emotional intelligence training with measurable, structured learning paths. This greenfield opportunity puts you in the driver's seat: choose the tech stack, design AI-powered features, and deploy production-quality code without bureaucratic roadblocks or legacy baggage.

Forget micromanagement and endless meetings. Here, you'll build autonomously, with direct feedback loops to user growth. Your mission? Transform product vision into technical reality, owning everything from initial architecture to production deployment.

This is where exceptional engineers thrive—where full-stack control meets meaningful impact and the freedom to execute at speed.

What You Will Be Doing

• Crafting comprehensive technical specifications with well-defined scope, architecture blueprints, and realistic delivery roadmaps
• Developing robust full-stack JavaScript solutions (React + Node.js) with sophisticated AI integrations that prioritize performance, maintainability, and user experience
• Implementing rapid test-deploy cycles to deliver value to users with maximum velocity
• Taking complete ownership of features from concept through deployment and beyond
  
  

What You Won’t Be Doing

• Wasting hours in coordination meetings navigating cross-team dependencies or negotiating release windows
• Following rigid, pre-defined task lists handed down from product management
• Spending your days untangling technical debt or patching minor issues in code you didn't write

• Practical experience implementing modern AI technologies and APIs (OpenAI, LangChain, or similar platforms)
• Strong ability to translate product requirements and UX goals into scalable, maintainable technical architecture
• Self-directed work ethic with proven capability to own complete implementation cycles independently
