AI Engineer, Agentic Ad Creative (Multimodal)

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
