I’m looking for an AI Engineer to help build an automated red-teaming product based on open-source models. This is a short-term, hands-on project for around 2 months, with an expected commitment of about 20 hours per week. The goal is to build a specialized red-teaming engine that can generate adversarial prompts across different risk domains, severity levels, and attack strategies — then automatically run those prompts against target AI models to identify bad cases, failure patterns, and safety gaps. 🔍 What you’ll work on Build red-teaming systems on top of open-source LLMs, including fine-tuning, prompt optimization, evaluation pipelines, and model orchestration. Design automated prompt generation workflows across risk domains such as self-harm, hate, violence, sexual safety, misinformation, fraud, cyber, and other high-risk areas. Generate prompts across different harm levels, from benign edge cases to policy-borderline and clearly unsafe scenarios, while maintaining structured taxonomies and evaluation criteria. Run automated tests against target models such as Gemma, Llama, Qwen, or other open-source / closed-source models to surface jailbreak patterns, over-refusal, under-refusal, and policy inconsistencies. Build feedback loops that turn model failures into stronger red-team prompts, improved eval sets, remediation recommendations, and continuous safety testing. 🧠 What I’m looking for Hands-on experience with open-source LLMs, fine-tuning, LoRA / QLoRA, RAG, model evaluation, and LLM inference pipelines. Familiarity with AI safety, red teaming, adversarial prompting, jailbreaks, safety evals, or trust & safety systems. Ability to build end-to-end systems, including data pipelines, model serving, eval harnesses, scoring, dashboards, and automation workflows. Bonus if you’ve worked on model safety, content moderation, policy evaluation, agentic testing, or automated eval infrastructure. ⏳ Project setup Duration: around 2 months Time commitment: about 20 hours per week Format: flexible / remote-friendly Stage: early-stage build, from 0 to 1 🚀 Why this is interesting This is not about manually writing red-team prompts one by one. The goal is to build a scalable system that can continuously generate, test, categorize, and learn from model failures — helping teams understand where AI models break, why they break, and how to improve them. If you enjoy working with open-source models, AI safety, red teaming, and fast 0-to-1 product building, I’d love to chat. Feel free to DM me if this sounds like you, or if you know someone who might be a good fit.

Description: I’m a non-technical founder building SoCalForeclosures.net — a subscription platform for Southern California real estate investors. Lead Members pay $149.99/month (capped at 8,000) to access scored off-market foreclosure and pre-foreclosure leads. Members work leads in a built-in CRM and sell deals through an internal marketplace to cash buyers (free tier or $99.99/month First Look). A working prototype is already built and deployed. Core features including user authentication, PayPal payments, marketplace (SoCalDeals), MyCRM pipeline, Phantom lead scoring engine, admin tools, and bot management screens are functional with demo data on a professional dark theme. Current honest status: The automated “bot army” that will pull real public distress signals from county recorders, courts, tax collectors, legal newspapers, trustees, and paid data sources is scaffolded but not yet actively ingesting live leads. A detailed signal catalog and county data sources are already documented. Project Scope (Fixed Price): I need an experienced senior full-stack developer to take the existing prototype and deliver a fully functioning, production-ready platform that is live and online. This is a single fixed-price engagement. Key deliverables for this project: Full code review and audit of the current Next.js + Express + PostgreSQL + Prisma codebase Polish and improve visual design and user experience across the member dashboard, lead feed, CRM, and marketplace so it looks professional for serious real estate investors Activate and productionize the real data pipeline (bot army) so it can ingest actual leads from public and paid sources according to the existing signal catalog Fix bugs, performance issues, technical debt, and operational problems Migrate hosting from the current European server to a reliable US-based provider with proper deployment pipeline, monitoring, and backups Stabilize the site so it runs reliably in production Deliver clear documentation and handover Important notes: This is not a from-scratch build. A substantial amount of the website and backend already exists and is deployed. The goal of this fixed-price project is to complete the remaining work and launch a fully functioning, live platform with real data capabilities. Once the website is successfully deployed live and online, we will negotiate a separate ongoing contract for maintenance, upgrades, new features, and additional work (including potential iOS and Android mobile apps). Tech stack: Next.js 14 (App Router) + TypeScript + Tailwind Express backend + PostgreSQL + Prisma Existing TypeScript bot framework (Playwright / Cheerio) PayPal payments, Twilio, Resend, Mapbox Ideal candidate: Senior full-stack developer with strong experience in TypeScript, Next.js, Prisma/PostgreSQL, and data pipelines or web scraping (public/government data sources) Experience taking prototypes to production, including hosting migrations and operational stability Comfortable working with an existing codebase and delivering clear recommendations to a non-technical founder Proactive, reliable, and quality-focused Project type: Fixed Price (one set price for the full scope above to get the platform fully live and functioning). To apply, please: Propose your fixed price for completing this project (review + polish + activate data pipeline + hosting migration + full production launch). Share 1–2 examples of similar past work (taking existing code to production, data platforms, or marketplaces). Briefly describe how you would approach reviewing and completing an existing prototype. Confirm your experience with US hosting providers and data pipeline / scraping work. Any questions about the current state or scope. Serious applicants will receive the full technical documents (Developer Brief, Signal Catalog, and County Data Sources) under NDA. Project owner is based in Southern California. US time zones preferred for easier communication.

# Full-Stack AI Engineer — Semantic Search + Next.js + Supabase (Long-Term, Contract-to-Hire) ## About We're building an AI-native platform that makes a large archive of recorded talks genuinely discoverable and useful: need-based semantic search over transcribed media, with a subscription product built around it. We have a clear product vision and architecture and are looking for a lead engineer to build the first version and grow with us long-term. Full product details are shared with shortlisted candidates under NDA — this post focuses on the engineering and the skills we need. ## The engineering challenge You'll build a two-part system that shares one database: 1. **A content pipeline (Python):** ingest recorded talks, transcribe them, chunk and enrich the transcripts with metadata using an LLM API, generate embeddings, and store everything in Postgres. 2. **A web app (Next.js):** fast, crawler-friendly, SEO-strong content pages with structured data; retrieval-based search that returns relevant source material with links/citations; user accounts; and Stripe-gated paid content. We care a lot about retrieval *quality* and clean, maintainable architecture — this is a real product, not a prototype. ## Required tech stack - **App:** Next.js (App Router), TypeScript, Vercel. Strong SSR/SSG, SEO, and JSON-LD structured-data experience. - **AI/backend:** Python; production RAG (embeddings, chunking, retrieval quality); LLM API integration. - **Data:** Postgres + **pgvector** (via Supabase); embeddings via a hosted model (Voyage/OpenAI). - **Auth & gating:** Supabase Auth with row-level security. - **Payments:** Stripe (subscriptions + one-time). ## Required skills - Shipped production Next.js (App Router) + TypeScript apps with strong SSR/SEO. - Built a real RAG / vector-search system in production — not a tutorial clone. - Comfortable in Python for data pipelines. - Postgres + pgvector and Supabase in production. - Stripe integration. - Plans before building; communicates clearly in writing. ## Nice to have - Audio/video transcription experience (Whisper / faster-whisper / Deepgram / AssemblyAI). - Agentic coding workflows (e.g., Claude Code). - Content-heavy SEO products or media libraries. ## Engagement - Hourly, contract-to-hire. ~20–40 hrs/week to start; long-term for the right person. - We start finalists on a **small paid test project** (a single self-contained slice of the pipeline) before the full engagement — that's how we evaluate fit. ## Confidentiality This is a proprietary product. Shortlisted candidates sign a mutual NDA before we share full scope and context. Please don't expect complete product details in the first exchange — strong technical applicants will have everything they need to be evaluated, and the rest follows the NDA. ## How to apply Applications that skip these are ignored: 1. **Start your proposal with the word `pgvector`** so we know you read this. 2. Link **two** projects: one live Next.js/SSR app, and one RAG/embeddings or LLM-integration project. Tell us what *you* personally built. 3. Answer briefly: *An offline embedding pipeline and a live search query must use the same embedding model — why does that matter, and how would you guarantee it?* 4. One line on your approach to chunking long-form audio/video transcripts for good retrieval.
