Head of Solutions

The person AI teams call when they need data that doesn't exist yet. Kaius builds the human data frontier AI can't scrape or synthesize. Our app, Kai, pays everyday people around the world for what they know. Our platform lets AI teams collect exactly the data they need, by language, place and person, across voice, image, video and text. We're a small team of repeat founders, backed by ValueStream Ventures and angels including the Cofounder & CTOs of Slack and Duolingo, Reddit's former CEO and an engineering leader at OpenAI. THE JOB

Every deal we do turns on one question: given what this team is trying to teach their model, what data do we collect, from whom, and how do we prove it's good? Right now our founders answer it. We need you to own it. You'll sit with research and post-training teams at frontier labs, voice AI companies and public sector programs, and turn 'our model is weak at X' into a program we can deliver. Then you make sure we do. WHAT YOU'LL DO

- Lead the technical side of every new customer conversation, alongside our CEO - Write the scope before we sign: who we collect from, where, how much, the rubric, the quality bar, the timeline and the price - Work with engineering and data operations so what we promise is what we ship - Bring patterns back to product. If three customers ask for the same thing, that's a roadmap item - Build what makes it repeatable: scoping templates, quality frameworks, pricing for custom work In your first 90 days you'll own scoping on every new deal, and customers will start asking for you by name. WHO YOU ARE

- You've been on the provider side of AI data. You've built data programs for model builders, not just bought them - You speak post-training: SFT, preference data, evals, RL. You can read a white paper and say what data would move the needle - You've written scopes and proposals that turned into real, delivered work - You're a builder. A pricing model, a quick tool, a rubric. You don't need a team to get started - You write clearly. We're remote, and concise writing is how we think clearly - Bonus: voice and audio data, multilingual collection, robotics or egocentric video PROBABLY NOT FOR YOU IF

You need a finished product and a delivery team behind you before you can move. Or your best work is a great demo or a great deck. We need someone who's shipped the thing and wants to do it again, better. WHY NOW

Hard, valuable, fun. The problem has no playbook, the market is wide open, and the team already likes each other. You'll be the first person in this seat, and you'll shape what it becomes. THE DETAILS

- San Francisco. You'll be in the room with customers. The rest of the team is remote-friendly - How we hire: No AI recruiter screens, no homework. A couple of hours working with us instead
