Description
Ready to break free from the conventional development grind? Welcome to a role that puts you in the driver's seat of technical innovation.
At Legends, we're revolutionizing emotional intelligence training through a cutting-edge D2C application. As our Senior Full Stack Engineer, you'll have carte blanche to architect, design, and implement solutions that matter. No bureaucracy, no legacy baggage – just pure, unfiltered technical ownership.
This isn't your typical engineering role where you're just another cog in the machine. Here, you're the architect, the builder, and the decision-maker. You'll be crafting an AI-powered platform that transforms how people develop their EQ, with the freedom to innovate and the authority to execute.
What you will be doing
Your mission, should you choose to accept it:
- Architect and craft comprehensive technical specifications that set clear paths to success
- Develop robust full-stack solutions using React and Node.js, seamlessly integrated with cutting-edge AI technologies
- Champion rapid deployment cycles with a focus on delivering immediate user value
- Take complete ownership of features from conception to production
What you will NOT be doing
Let's be clear about what you won't find here:
- No endless coordination meetings or bureaucratic bottlenecks
- No micromanagement or rigid task assignments from above
- No time wasted wrestling with outdated code or fixing others' minor issues
Key responsibilities
Your core mission is to spearhead the evolution of Legends through autonomous development of sophisticated, user-centric features that define the next generation of EQ training technology.
Candidate requirements
The ideal candidate brings:
- A proven track record of launching production-grade consumer applications
- Deep expertise in full-stack JavaScript development, particularly with React and Node.js
- Demonstrated mastery of modern AI technologies and integrations (OpenAI, LangChain, etc.)
- Sharp product intuition and the ability to transform user needs into technical solutions
