About Admanage.ai

We build the Cursor for ad management. Admanage.ai helps companies launch ads 10x faster across Meta, Tik Tok, Google, Snapchat, Pinterest, Reddit, and more. Created by top performance marketers who have managed over $50M+ in ad spend, our mission is to level the playing field by giving every business access to enterprise‑grade ad automation tools.

We make it possible to launch hundreds of ads in seconds. What takes a media buyer 60 minutes in Ads Manager takes us under a minute, a 96% cut in launch time. In the last 90 days alone, our users launched 2.3M+ ads across 194,000+ batches, and we serve about 10,000 marketers daily at brands like Canva, Stanley, Wise, NordVPN, and Perplexity.

Now we’re building AI‑powered tools to programmatically create, launch, and manage ads. This is where you come in.

Why This Role Rocks

This is a designer‑first role with real ownership. You'll design and ship the interfaces that top advertisers use to launch and manage hundreds of thousands of ads a month: dense data tables, real‑time sync from Meta, and workflows spanning a dozen ad platforms.

Tech Stack
  • Design / AI tooling:
    Claude Code, Codex, Claude Design, Figma
  • Frontend:
    Next.js 14, React 18, Tailwind CSS, Radix UI, Framer Motion
  • State management:
    Zustand
  • Testing:
    Vitest
  • Backend (light exposure):
    Node.js, Prisma, MySQL
  • Infra:
    Cloudflare R2, AWS S3, Vercel
What You’ll Do
  • Own the look, feel, and UX of a product launching millions of ads a quarter.
  • Talk to customers, understand their actual problems, and design the shortest path to the outcome they want.
  • Take complex, data‑heavy workflows and make them radically simple: cut clicks, cut screens, cut confusion.
  • Prototype and build with Claude Code, Codex, and Claude Design; refine your work into pixel‑accurate, accessible, reusable production components.
  • Build and maintain our design system: spacing, typography, colour, motion, components.
  • Ship features end to end: idea → design → build → polish.
  • Level up your engineering skills with support from experienced engineers and founders.
Qualifications
  • Product obsession: you start from the customer’s problem, not the pixels; you measure your work by outcomes achieved, not screens designed.
  • Belief that simplicity is beautiful: you instinctively remove steps rather than add options.
  • Design‑first mentality: you obsess over spacing, hierarchy, typography, motion, and clean, consistent UI.
  • Portfolio of shipped product design work (web apps, dashboards, or tools are a big plus).
  • Willingness to build what you design, and openness to learn Claude Code and Codex; some HTML/CSS or React experience helps but curiosity and learning speed matter more.
  • Sensitivity to details that other people miss.
  • Concern for UX, performance, and design systems.
  • Clear communication, speed, and fit in a startup culture.
Bonus Points
  • Hands‑on experience with Claude Code, Codex, Cursor, or similar AI build tools.
  • Experience with React/Next.js or Tailwind CSS.
  • Experience designing data‑heavy products, dashboards, or B2B SaaS.
  • Familiarity with ad platforms (Meta, Tik Tok, Instagram) as a user or designer.
Benefits
  • Design and ship product used by about 10,000 marketers daily.
  • Learn to build with AI tools alongside experienced engineers and founders.
  • Solve hard UX challenges in adtech.
  • Own what you design and shape our product culture.
  • Grow into a Lead Design role as the company scales.
How to Apply

Send your portfolio, Linked In profile, and two to three lines on the best interface you’ve designed lately. Bonus: links to anything you built or prototyped that makes you proud.

Interview Process
  • Take‑home task: redesign a small section of a sample UI and explain your thinking. If you can prototype it with an AI tool, that’s a plus.
