Description
Ready to break free from the assembly line of feature factories? Craving architectural autonomy and true product ownership? Tired of building yet another CRUD app with an AI chatbot slapped on as an afterthought?
This role is your escape hatch.
Step into the engineering leadership position at Legends, a groundbreaking D2C application revolutionizing emotional intelligence education. We're teaching EQ with the same rigor applied to technical skills: structured, measurable, and consistently effective. This greenfield opportunity puts you in the driver's seat—defining the tech stack, crafting AI-powered features, and deploying pristine code without bureaucratic roadblocks or legacy system headaches.
Forget the theater of sprint planning or the tedium of Jira ticket management. You'll build independently with complete autonomy, working directly with growth metrics. Your mission: transform product objectives into technical reality, owning everything from initial code commits to production deployment.
This is the destination for elite engineers who demand full-stack control, direct user impact, and the freedom to execute with velocity.
What you will be doing
- Crafting comprehensive specifications that clearly define scope, architecture, and delivery timelines
- Developing robust full-stack JavaScript solutions (React + Node.js) with sophisticated AI integrations that prioritize cleanliness, performance, and production readiness
- Executing rapid test-deploy cycles to deliver functional features to users with minimal delay
- Taking complete ownership of features from conception through implementation
What you will NOT be doing
- Wasting hours in coordination meetings negotiating dependencies between teams or planning release schedules
- Following rigid task lists cascaded down from product management
- Spending valuable time maintaining outdated codebases or fixing trivial bugs introduced by others
Key responsibilities
Spearhead the development of Legends' next iteration by autonomously conceptualizing, constructing, and deploying premium-quality user-facing features that drive engagement and results.
Candidate requirements
- Demonstrated track record of delivering consumer software at production-grade quality
- Mastery of full-stack JavaScript development (React + Node.js ecosystem)
- Proficiency with contemporary AI frameworks and APIs (OpenAI, LangChain, or equivalent)
- Expertise in converting user experience and product objectives into implementable technical architecture
- Self-sufficiency and comfort with end-to-end ownership in an independent work environment
Nice to have
- Prior experience developing native iOS applications
- Professional background in personalization systems, content delivery platforms, or educational technology products
