Quick Summary

Role Overview

This role involves building and owning an end-to-end agentic pipeline that generates thousands of AI-driven video and image ads daily. You will integrate performance feedback loops to refine creative assets across major platforms like Meta, TikTok, and Google.

Key Responsibilities

  • Extend the LLM critic loop to include video and copy regeneration
  • Build a rapid video pipeline that generates platform-ready ads in under 90 seconds
  • Develop a generative model router to optimize quality and cost per asset
  • Create a VLM-based policy checker to ensure compliance with advertising standards
  • Train and deploy brand-specific LoRA and DreamBooth checkpoints for production
  • Implement event-triggered pipelines to generate ads instantly based on real-time news

Requirements Snapshot

  • Deep technical expertise in diffusion models and video generation workflows
  • Proven experience building and optimizing ComfyUI or similar inference pipelines
  • Strong portfolio of public artifacts such as Replicate models or GitHub repositories
  • Ability to design systems with cost as a primary constraint
  • Thorough understanding of social media advertising policies and creative performance

Expected Impact

You will transform the company's growth engine by scaling the creative pipeline from thousands of images to high-quality, cost-effective video content. By closing the loop between performance data and asset generation, you will drive significant improvements in CPI and ROAS while maintaining a high volume of fresh, compliant ads.

About the Role

Every install we buy starts as a creative someone (or something) made. We're rebuilding that creative pipeline so that *something* is an agent — one that generates thousands of images and videos a day across Meta, Google, TikTok, Pinterest, Reddit, and Snap; watches CPI and ROAS come back; and gets sharper every cycle.

We're hiring the engineer who owns this agent end-to-end.

What You’ll Do (representative projects)

  • CPI-feedback creative critic loop — Extend our LLM critic + performance-feedback regeneration from images-only to images + video + copy, all closed-loop, all running unsupervised at thousands of variants per day.
  • Video pipeline — Build from a topic + product brief to a platform-ready 9:16 vertical ad — script, scene plan, b-roll, voiceover (ElevenLabs / Hedra), captions — in under 90 seconds per iteration, under $0.50 per iteration.
  • Generative model router — Pick the right model per brief (Flux Schnell vs Pro, Veo 3, Sora, Runway Gen-3/4, Kling, Hailuo), minimizing $/asset under a quality floor. Prove your routing strategy in production via A/B.
  • Policy pre-flight checker — Build a VLM (GPT-4o vision / Gemini / Claude vision) that vets every frame and caption against current Meta / Google / TikTok ad policy before upload. Block 100% of would-be-rejected creatives at the source.
  • Brand-style LoRA / DreamBooth checkpoint — Train and ship on past CPI-winning ads. Deploy serverless on fal / Replicate. A/B against base Flux on real spend.
  • Event-triggered ad pipeline (video) — Earthquake hits at 14:02 → by 14:12 you have 50 paused video variants in Meta and TikTok, each with platform-specific aspect ratios and locale-specific voiceover.

You May Be a Good Fit If

  • You understand diffusion and video models viscerally — you’ve debugged them, trained a LoRA, optimized inference, built a ComfyUI workflow you’d defend in public.
  • You can name your daily model stack — Flux vs SDXL vs Veo vs Sora vs Runway vs Kling vs Hailuo — and explain when each wins, where each breaks, and what you’d reach for at $0.01/asset vs $0.50/asset.
  • You have public artifacts — a fal demo, a Replicate model, a Civitai upload with >100 downloads, a viral X thread of your generations, a ComfyUI workflow on GitHub. Portfolio matters more than resume.
  • You have scroll-stopping instinct — you know what makes someone not swipe past an ad in the first 3 seconds.
  • You think about cost as a first-class design constraint — $/asset, $/click, $/install. Cost arbitrage between model tiers is something you’ve actually shipped.
  • You’ve read Meta Advertising Standards / TikTok branded-content rules end-to-end — policy is a pre-deploy gate, not a post-mortem.
  • You’re a builder — Idea → working pipeline → first 100 ads shipped → CPI data back → tighter loop. Not “I’ll spec it for Q3.”

Strong Candidates May Also Have

  • Pretrained or significantly advanced a VLM (not just SFT’d or LoRA’d one).
  • Open-sourced a ComfyUI custom node, a diffusers extension, or a Replicate model with real traction.
  • Deployed serverless inference on fal / Replicate / Modal at scale (>10k req/day).
  • Shipped a video product end-to-end: script → scene plan → b-roll → voiceover → captions → final cut.
  • Authored a public take on generative video model failure modes that other engineers cite.

Not the Right Fit If

  • You’ve only ever prompted hosted models — you’ve never trained a LoRA, written a ComfyUI workflow, or deployed a custom checkpoint.
  • Your creative experience stops at Photoshop or Canva templates. You can’t tell us why a Flux generation has bad hands or why Veo 3 over-saturates skin.
  • You think “AI creative” means asking GPT to write ad copy.
  • You’re an academic researcher chasing first-author papers. We ship.
  • You’re a brand-side creative director without engineering depth. We need someone who debugged a CUDA OOM at 2am because the generator was holding up the next batch.

How We’ll Evaluate You

Take-home: build a small agentic creative pipeline end-to-end — your call: image-only or short video, hosted or self-served, model of your choice. Walk us through what you built and every model / cost / quality decision behind it. Conversations with the team follow. Portfolio matters more than resume — if you can’t show a public artifact, please come back when you can.

What You Get

  • Competitive Bay Area comp + meaningful equity.
  • Unlimited generative model budget — fal, Veo, Sora, Runway, ElevenLabs, OpenAI image, Anthropic vision, Hedra, Kling. We expect you to burn through it.

About the Team

You’d join the team building NewsBreak’s agentic growth platform. We already ship a CPI-feedback creative critic loop, event-driven creative pipelines, and multi-platform ad-upload tooling for Meta, Google, and TikTok. Your job: take the creative side from “thousands of images per day” to “video too, smarter every cycle, cheaper every month.”

  • Health, dental, and vision care for you and your family (100% coverage for employee)
  • Top-tier 401(K) plan with company matching
  • Paid time off and paid holidays
  • FSA, HSA and commuter benefits programs
  • Team activity budget
