We need to output HTML fragment with sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule as needed. We must not repeat job title. We need to extract content from posting. Let's parse posting: - Intro: "Software Engineers: Let 100+ Companies Compete For You Fonzi is an AI recruiting company. No job boards. No recruiter spam. Companies request to interview you and submit salary bids upfront. Every week, hiring managers at 100+ pre-vetted startups in NYC and San Francisco review a curated group of engineers. They're reading profiles optimized by our team to surface what matters: what you've built, how you think about systems, and whether you're the kind of engineer who ships. Companies on Fonzi are Applied AI startups, Frontier labs, Hypergrowth startups, PE firms starting lean AI teams and more. They're backed by investors like A16z, Sequoia Capital, General Catalyst, Y Combinator and more. How It Works 2-minute applicationWe reach out, learn what you're building and what excites you, and optimize your profileHiring managers review the cohort and request interviews with candidates they wantCompanies submit competing salary bids directly to youYou only interview where you're genuinely interestedCompletely free. We have an iMessage agent + humans in the loop you can text anytime w/ questions or requests to help handle scheduling and coordination" - "Who We're Looking For" bullet points: Have built AI-powered products end-to-end, not just prototypes, but systems handling real users; Can talk fluently about retrieval, memory, agent frameworks, context engineering, eval pipelines and anything else at the cutting edge; Combine strong software engineering fundamentals with deep awareness of what's happening at the frontier of LLMs and agentic systems; Thrive in startup environments where the problem is ambiguous and the team is small; Have 2-8 years of experience, ideally with experience at at least one high-growth company - "What You'll Build": list of projects: Agentic systems that automate complex, multi-step workflows across healthcare, legal, fintech, logistics, and compliance; Production RAG pipelines powering domain-specific knowledge retrieval at scale; AI-native products where the intelligence layer is the product, not a feature; Multi-agent orchestration systems with tool-calling, memory, and reasoning capabilities; Eval and safety infrastructure that makes AI systems trustworthy enough for enterprise deployment; Full-stack AI applications from MVP to enterprise-grade, serving real customers today - Compensation: "$200,000 – $400,000+ base salary depending on experience and role. Many positions include meaningful equity at pre-seed through Series B stage companies." - Interview Process: "Screening conversation looking for communication skills, cultural fit, genuine curiosity about AI; Technical deep-dive talks on architecture thinking, how you'd design an AI system for a real problem; Coding or pairing sessions building" - Final line: "If you're an engineer who's been building with AI because you can't stop thinking about it we want to hear from you." We need to decide sections: About the role (maybe description of Fonzi and how it works). Responsibilities (maybe what you'll build). Requirements (experience, years, etc). Qualifications (maybe skills like AI-powered products, frameworks). Skills (maybe list of technical skills). Benefits (maybe free service, iMessage agent, etc). Pay (compensation). Schedule (maybe not given). We should only include sections with real content. We have Pay: compensation given. Benefits: maybe "Completely free. We have an iMessage agent + humans in the loop you can text anytime w/ questions or requests to help handle scheduling and coordination." That's a benefit. Also maybe "No job boards. No recruiter spam." Could be benefit. Schedule: Not given. So omit. We need to avoid filler like "commensurate with experience". Not present. We need to use

for section headings. Use
  • for any list of duties/requirements/benefits. Use

    for prose. We must not repeat job title as heading. So no heading "Software Engineers". Use sections like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay. We need to preserve all substantive information; do not invent or summarize away detail. So we need to include all details. Let's craft sections: About the role: description of Fonzi, how it works, that companies request interviews, salary bids upfront, free service, iMessage agent, etc. Responsibilities: maybe "What You'll Build" list. Requirements: experience 2-8 years, ideally high-growth company, etc. Qualifications: maybe "Have built AI-powered products end-to-end..." etc. Skills: maybe list of technical topics: retrieval, memory, agent frameworks, context engineering, eval pipelines, LLMs, agentic systems, etc. Benefits: free service, iMessage agent + humans, no job boards, no recruiter spam, etc. Pay: compensation range and equity. We need to ensure we don't duplicate content. Let's extract each piece. From intro: "Software Engineers: Let 100+ Companies Compete For You Fonzi is an AI recruiting company. No job boards. No recruiter spam. Companies request to interview you and submit salary bids upfront. Every week, hiring managers at 100+ pre-vetted startups in NYC and San Francisco review a curated group of engineers.

We have an iMessage agent + humans in the loop you can text anytime w/ questions or requests to help handle scheduling and coordination" We can combine into prose. Now "Who We're Looking For": bullet list. Now "What You'll Build": bullet list. Now Compensation: "$200,000 – $400,000+ base salary depending on experience and role. Many positions include meaningful equity at pre-seed through Series B stage companies." Interview Process: maybe could be part of About the role or Responsibilities? But we could include as part of About the role? However we have no section for Interview Process; we could include under About the role or maybe under Responsibilities? But better to include under About the role as part of process. But we need to preserve all substantive information; we can include interview process details in About the role or maybe a separate section like "Interview Process". But the instruction only lists specific headings; we can add other headings? It says use

    for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). It implies we should use those headings when appropriate, but we could also add other headings? It says "include a section ONLY when the posting has real, specific content for it". It doesn't forbid other headings, but the examples are those. Safer to stick to those headings. So we need to map content to those. Interview process could be part of About the role or Responsibilities. Probably About the role includes how it works. We'll include interview process details in About the role. Now let's craft HTML. We'll start with

    About the role

    then

    ...

    containing description. Then

    Responsibilities

    then
    • ... each bullet from What You'll Build. Then

      Requirements

      then
      • ... from Who We're Looking For: experience 2-8 years, ideally high-growth company, thrive in startup environments, etc. Then

        Qualifications

        then
        • ... from Who We're Looking For: built AI-powered products end-to-end, talk fluently about retrieval, memory, agent frameworks, context engineering, eval pipelines, combine strong software engineering fundamentals with deep awareness of frontier LLMs and agentic systems. Then

          Skills

          then
          • ... maybe list of specific skills: retrieval, memory, agent frameworks, context engineering, eval pipelines, LLMs, agentic systems, tool-calling, memory, reasoning, multi-agent orchestration, RAG pipelines, full-stack AI applications, etc. But we need to avoid duplication; we can list skills from the bullet points. Then

            Benefits

            then
            • ... from intro: No job boards, No recruiter spam, Companies request to interview you and submit salary bids upfront, Free service, iMessage agent + humans in the loop you can text anytime w/ questions or requests to help handle scheduling and coordination. Then

              Pay

              then

              ...

              with compensation and equity. We should not include Schedule. Make sure we don't repeat content unnecessarily but preserve all. Let's write. Check for any duplicated lines: we need to avoid repeating same info in multiple sections. We'll try to allocate each piece to one section. Let's list all distinct pieces: - Company description: Fonzi is an AI recruiting company, no job boards, no recruiter spam, companies request to interview you and submit salary bids upfront, every week hiring managers at 100+ pre-vetted startups in NYC and SF review curated group, they read profiles optimized by our team to surface what matters: what you've built, how you think about systems, whether you ship.
