Description
Tired of playing the corporate JIRA ticket game? Ready to wield complete architectural control and build something that matters?
This is your opportunity to break free.
Step into the engineering leadership role at Legends, where we're revolutionizing emotional intelligence education through our D2C app. We're teaching EQ with the same structured, measurable approach used for technical skills. As our Senior AI Engineer, you'll have a blank canvas to establish the tech foundation, craft AI-enhanced features, and deploy production-quality code without bureaucratic obstacles or legacy system headaches.
Forget about meaningless ceremonies and endless meetings. Here, you'll build independently with complete autonomy, working directly with growth metrics. Your mission: transform product objectives into technical realities and own every aspect from initial code to production deployment.
This position is designed for elite engineers who demand full-stack control, crave direct user impact, and thrive in a high-velocity environment.
What you will be doing
- Crafting comprehensive technical specifications with well-defined scope, architecture decisions, and delivery roadmaps
- Developing elegant, efficient full-stack JavaScript solutions (React + Node.js) with sophisticated AI integrations
- Implementing rapid test-deploy cycles to deliver functional features to users with maximum velocity
- Taking complete ownership of features from conception through implementation and beyond
What you will NOT be doing
- Wasting hours in coordination meetings negotiating dependencies or debating release schedules
- Executing rigid task lists dictated by product management without engineering input
- Spending your valuable time maintaining outdated codebases or fixing trivial bugs created by others
Key responsibilities
Your core mission: Independently architect, develop, and launch a next-generation version of Legends by creating and implementing high-quality, user-centric features that deliver measurable value.
Candidate requirements
- Demonstrated track record of delivering consumer-facing software at production scale
- Expert-level full-stack JavaScript capabilities, particularly with React and Node.js ecosystems
- Practical experience implementing modern AI technologies and APIs (OpenAI, LangChain, or similar platforms)
- Exceptional ability to convert product and UX objectives into scalable technical architecture
- Self-directed work ethic with proven success in autonomous, end-to-end implementation environments
Nice to have
- Native iOS application development expertise
- Professional background in personalized content delivery systems, educational technology, or learning platforms
