Founding Builder

Salary

$200k+ + Equity

Company Description

super{set} is a San Francisco venture studio that conceives, builds, and launches AI-native companies from scratch, providing builders with unique equity across its entire portfolio of high-growth startups.

Job Description

Join super{set}’s Signal program to transform raw startup concepts into production-ready AI platforms in weeks. As a hands-on founding architect, you will leverage a 10x AI-augmented stack to build multi-agent systems and full-stack MVPs. This mission-critical role offers extreme autonomy to define categories that don't yet exist while shipping code daily.

Location

San Francisco, USA

Why this role is remarkable

Participate in the Signal program, the core engine of a proven venture studio that has successfully built and exited multiple high-impact technology companies.

Gain unique financial upside through equity across the entire super{set} portfolio, offering a stake in multiple AI ventures rather than a single startup's risk.

Master a cutting-edge 10x development workflow using AI-native tools like Claude Code and Cursor to build complex agentic architectures at unprecedented speeds.

What You Will Do

Take napkin-sketch startup concepts to production-grade MVPs with real users in weeks, owning everything from database schemas to the final UI pixel.

Architect and deploy complex autonomous systems using modern LLM orchestration frameworks like Agno or LangGraph to solve real-world logic challenges.

Represent the engineering culture of super{set} by engaging with the global AI developer community, publishing technical writing, and presenting at top-tier conferences.

The ideal candidate

Proven track record of shipping successful greenfield projects from scratch as a founder, founding engineer, or lead builder of production-grade products.

Expert-level fluency with AI-augmented development workflows and a polyglot background across Go, Rust, or Python for backend and React/Next.js for frontend.

Excited by in-person collaboration in downtown San Francisco, thriving in high-velocity whiteboard sessions where zero-to-one product decisions happen in real-time.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

Jill is the AI recruiter working for the company. She recruits from Jack's network.

If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
