🎯 Your Role & Responsibilities

As a Fullstack SWE, you won't just be closing tickets; you will be owning entire product verticals. Your primary objective is to bridge the gap between complex AI capabilities and a seamless user experience.

Key Objectives

• Architect and implement new features from database schema to UI components.
• Optimize the latency of AI responses to ensure a "real-time" feel.
• Collaborate directly with founders to define the product roadmap.
• Refine prompt engineering strategies to improve output quality.

A Glimpse into the Code

You might find yourself writing logic similar to this to handle AI stream processing:

async function generateRefinedText(input: string): Promise<ReadableStream> {
  const response = await openai.chat.completions.create({
    model: "gpt-4",
    messages: [{ role: "user", content: `Refine this: ${input}` }],
    stream: true,
  });
  return response;
}

🧬 Who You Are

Quill is looking for a "product-minded" engineer. This means you care as much about the why as you do about the how.

Required Qualifications:

• Proficiency in TypeScript and React.
• Experience building and scaling backend services.
• Ownership Mentality: You don't wait for a spec; you find the problem and fix it.
• Curiosity: A deep interest in the evolving landscape of Large Language Models (LLMs).

The "Ideal" Candidate Equation: We believe the perfect fit can be modeled as: $\text{Candidate Value} = (\text{Technical Skill} \times \text{Product Intuition}) + \text{Speed of Execution}^2$

• Equity: Significant ownership in a YC-backed venture.
• Flexibility: A culture that values output over hours spent in a chair.
