Product & Design Co-founder — United States

We're building an AI-native operating system where your intent becomes the interface.

Today's computers force people to navigate applications, manage windows, and constantly switch contexts to accomplish even simple tasks. AI has made software more intelligent, but most of our interfaces haven't fundamentally changed.

5wEfakc is rethinking this from the ground up. Instead of making people adapt to software, we're building software that adapts to people—generating interactive interfaces and unified workspaces around what they want to accomplish.

We're starting with a desktop experience for macOS and Windows, with the long-term ambition of building a standalone operating system.

The RoleWe're looking for an exceptional Product & Design Co-Founder to help turn this vision into a product millions of people will love.

This is not a traditional product management role. We're looking for someone who can think like a founder, design like a world-class interaction designer, and execute like a product leader.

You'll work directly with the CEO to shape the product vision, define the core experiences, and determine what we build first.

You'll own:

• Product strategy: Identify compelling use cases, define our early users, and prioritize the experiences that make 5wEfakc valuable.

• Interaction design: Invent intuitive ways for people to interact with AI-generated interfaces, applications, and workspaces.

• Product development: Translate ambitious ideas into clear product requirements, prototypes, roadmaps, and engineering milestones.

• Design direction: Establish the UX principles, component systems, and interaction patterns that guide our generative UI.

• Product validation: Test experiences with real users, learn from feedback, and iterate quickly.

• Cross-functional leadership: Work closely with engineering and creative design to ship cohesive, polished experiences.

Who We're Looking ForWe're particularly interested in someone with:

• Strong experience building and shipping consumer software, ideally from zero to one.

• Exceptional product intuition and the ability to turn ambiguous ideas into concrete experiences.

• Deep expertise in UX and interaction design, beyond visual aesthetics.

• Experience defining product roadmaps, prioritizing features, and leading execution.

• An understanding of what makes products intuitive, delightful, and habit-forming.

• Technical fluency and the ability to collaborate with engineers on ambitious products.

• The confidence to challenge assumptions, make difficult tradeoffs, and take ownership.

We care more about what you've built and how you think than your title or previous employers.

What Makes This DifferentYou'll have the opportunity to shape the foundations of a new computing experience, not simply improve an existing product.

You'll be joining at an early stage, when fundamental decisions about the product, interaction model, and user experience are still being made.

We're looking for a genuine partner who wants to help define the future of personal computing—not someone waiting for a feature specification.

Compensation & CommitmentThis is an equity-based cofounder opportunity, with no cash salary initially. We are looking for someone comfortable with early-stage startup risk and motivated by building a company over the long term.

A meaningful founder-level equity stake, subject to vesting, will be negotiated based on experience, commitment, and responsibilities. Future salary will depend on the company's financing and financial position.

Interested?Tell us about a product you've built or helped take from idea to launch, what you personally owned, and why you're interested in rethinking how people interact with computers.

• We'd especially love to see examples of thoughtful interaction design, unconventional product ideas, or products you've brought to life with small teams.
