Frontend Engineer (AI / LLM Product)

Feb–May 2026 · Zero Bureaucracy · Extreme Ownership · Real AI in Production

 

Build the interface to AI that navigates bio-tech regulation — fast, clean, and decisive. We’re a lean, high-velocity team building an LLM-powered bio-tech regulatory platform that transforms complex regulatory workflows into clear, usable AI systems. This product turns dense, high-stakes regulatory knowledge into tools professionals actually rely on.

This is not research. This is not internal tooling. This is production software where accuracy, clarity, and speed matter.

We’re hiring a frontend engineer who ships fast, thinks independently, and thrives in ambiguity.

This is not a maintenance role. This is build-from-zero → ship-to-production → iterate relentlessly.

 

Duration: February–May 2026

Compensation: Based on impact, commitment, and skill

Schedule: Fully remote · Fully flexible · No time tracking. Output matters. Hours don’t.

Mentorship: Direct access to a senior CTO (30+ years experience)

Future: Strong potential for extension or full-time role in Q3 2026

 

The Mission

You will own the frontend of an AI-native product where humans interact directly with LLM systems handling complex regulatory logic.

Your work determines how powerful AI feels when the stakes are real:
clarity, trust, speed, and usability.

 

You will:

  • Build production-grade interfaces using React (critical), Next.js, and TypeScript
  • Design fast, responsive, high-performance UI at startup speed
  • Integrate with backend services built in Node.js
  • Work hands-on with LLM APIs (OpenAI, Anthropic, etc.)
  • Collaborate directly with the CTO — rapid feedback, high trust, zero bureaucracy
  • Ship clean, maintainable code under real deadlines
  • Operate at ~80% frontend / 20% full stack
  • Success is measured by what ships — not by meetings or online presence.

 

Who Thrives Here

  • You act fast, adapt faster, and don’t wait for permission.

 

You bring:

  • Strong, hands-on React experience (non-negotiable)
  • Solid command of Next.js, TypeScript, and modern frontend tooling
  • Comfort making high-quality technical decisions in ambiguous environments
  • A self-starter mindset with high internal drive
  • Strong instincts for performance, UX, and code quality
  • Startup mentality: bias toward action over discussion
  • The ability to learn new systems extremely fast.
  • Formal credentials matters, but execution decides.

 

Education

  • BS in Computer Science required
  • Currently pursuing an MSc in Computer Science
  • Second-year MS students strongly preferred

 

Bonus Signal (Nice to Have)

  • Experience with LLMs or AI-powered products
  • Exposure to regulated domains (bio-tech, legal, compliance, finance)
  • Startup, hackathon, or open-source background
  • Independent projects with full ownership end-to-end
  • Demonstrated rapid learning in unfamiliar technical stacks
