Full Stack Developer

Lab3 is looking for a sharp, adaptable Full-Stack Developer who thrives in fast-moving environments and knows how to ship features without cutting corners. You'll work across our stack — React, Vite, Node.js, and Firebase/Firestore — building and iterating on products that matter. This isn't a role where you sit back and wait for specs. You'll need strong judgment, the ability to context-switch between priorities, and the discipline to document what needs improving even when the current sprint demands speed. You understand that clean database structures, secure-by-default practices, and well-organized code aren't nice-to-haves — they're the foundation.
You're comfortable working with AI-assisted development tools and LLM APIs, and you bring a builder's mindset to everything you touch.
This is a full-time position with working hours of 9:00 AM – 5:00 PM EST, Monday through Friday. We follow the USA holiday calendar. Consistent availability during these hours is non-negotiable.
Excellent written and spoken English is a firm requirement. Our team communicates constantly through written documentation, calls, and async updates. Candidates who do not demonstrate strong English proficiency will not be considered.
