Who we’re looking for
- Build like a founder. You think in bets, ship fast, sweat the details, and are an exceptional individual contributor.
- Live and breathe the online AI and marketing scene – you’re experimenting with tools and models before they trend.
- Know how to create beautiful, intuitive-to-use web applications without bloated teams or endless roadmaps.
- Think in systems: front-end, back-end, APIs, hosting, auth, and analytics – you stitch it all together fast and clean.
- Care about performance, UX, and making things feel right.
- Can demonstrate excellence in previous work: side projects, MVPs, or anything you’ve built. That’s more valuable to us than resumes.
What you’ll be working on
- A real product (not a prototype) that helps our agency continue to innovate and serve our ecommerce brands in a new way, directly helping them improve ROI.
- Modern features like: full LLM integration, dashboards, creative reporting, management, and asset generation.
- A modular, fast-to-deploy tech stack that supports rapid iteration.
- Direct collaboration with the founder and small team to define product, ship features, and talk to users weekly.
Requirements
- Excellent communication skills.
- Full-stack excellence from frontend to backend, database, AI tooling, and deployment.
- A public body of work or side projects (GitHub, portfolio, X threads, indie apps, etc.)
- Deep curiosity and activity in AI tools, agents, automation, and LLM frameworks.
- Comfortable shipping solo and owning end-to-end dev.
- Bonus: experience building internal tools, marketing tech, or anything in ecommerce/ads.
What you get
- Salary: Competitive, based on experience.
- Location freedom: Remote-friendly.
- Impact: Build something real and used by real brands from day one.
- Backing: We’re profitable, fast-growing, and work with top brands in the space.
To Apply
Please send your GitHub and ideally x.com profile as part of your application - a resume alone will not be considered. This isn’t just another job. This is for someone who wants to own the build of something defining. You already live in the AI x builder ecosystem, and you’re looking for the right team, timing, and opportunity to make a dent.
If that’s you – reach out with a short note, links to your work, and tell us what you’re excited to build next.
