The Opportunity FutureSight is seeking an applied AI builder to co-found and lead the technical direction of a new B2B AI venture from the ground up. This is a co-founder partnership with founder-level equity and founder-level authority, not a salaried executive role.

We are looking for someone who can take a vague problem, frame it clearly, design the right system, and turn it into something customers actually use and trust.

What you'll own As Co-Founder CTO, you will set the venture's technical direction and lead its execution. This is a co-founder role, not a CTO hire. Technical Direction — Own problem framing, architecture, system design, and product judgment from day one, translating rough product intent into structure, context, and specs that both humans and AI systems can execute against Build — Use modern tools and frontier models to move fast without sacrificing quality or maintainability, designing agentic systems with first-principles thinking and knowing when orchestration adds genuine leverage versus when simplicity is the better call Customer Market — Be the primary technical voice in early customer conversations, understanding real workflows and shaping the right product rather than just shipping quickly Traction Before Scale — Prove there is something worth scaling before thinking about scaling it, focusing on traction first and team-building second Capital — Contribute to fundraising, from investor conversations to due diligence Team — Recruit and grow a technical team when the time is right, and establish the cultural foundation of the company Co-Founder Profile Proven track record of shipping AI products to real users under real-world constraints — not research, experiments, or prototypes Deep practical experience with frontier models, LLM-based systems, and agentic architectures, with strong system design instincts and a bias for simplicity and maintainability Strong translation layer skills — able to turn messy product intent into clear structure, constraints, and specs that both humans and AI systems can act on Close to the customer, comfortable in customer conversations, and able to let real workflows shape what you build Rigorous about verification — feedback loops, evaluation, and systems that can be trusted Prior experience as a technical co-founder or early engineering leader, with fundraising experience a strong plus Founder at heart — energized by ambiguity, able to go far alone, and ready to commit fully How to Apply Please submit your resume, LinkedIn profile, and a brief note on why this venture aligns with your goals as a founder.

Shape the customer experience end-to-end across onboarding, identity flows, sending and managing money, and payments-related edge cases. Lead product design through the full lifecycle: discovery, user research, prototyping, and high-fidelity execution. Collaborate closely with engineering and product to ship polished, well-considered experiences quickly. Bring a strong point of view on how AI-assisted design tools are changing the craft and put that thinking to work day-to-day. What We're Looking For Required 2+ years of experience in a product design role. Hands-on experience designing fintech or payments products — specifically onboarding flows and money movement UX. Familiarity with design-focused AI tools and a perspective on how they'll evolve day-to-day design work. Strong fundamentals in visual design and problem-solving. Based in California — candidates outside of California will not be considered at this time. Nice to Have Formal education in design or a related field (not required). Experience working at a similarly early-stage startup or building a design practice from zero. Background at consumer fintech, payments, or financial services companies. Tools Figma (primary design tool) Location This is a hybrid role based in San Francisco, CA . Candidates must be located in California. Compensation Benefits Compensation details were not provided for this role. As a founding hire at a seed-stage startup, equity participation is expected to be a meaningful part of the total package.

New York City | Full-Time | Founding Team About Futureproofing FutureProofing has partnered with a prolific M A investment banker to build an end-to-end AI platform for investment banking, a category that has been talked about far more than it has been built. The MVP is roughly a month out. We are looking for an AI engineer who has taken products from zero to one to join a team of senior engineers and carry the product from MVP to market. What You'll Do Take the product from MVP to something real customers rely on Build with LLMs, agents, RAG, and evaluation as core product surface, not as bolt-ons Work directly with the founding team on what gets built and why Dig into the parts of the system that need real ownership: data pipeline, infra, model integration Move fast alongside engineers who already know how to ship What We're Looking For 7+ years shipping production software, with meaningful time at an early-stage company You have taken at least one AI-powered product from nothing to real users in production, and can explain the tradeoffs you made along the way Deep in modern stacks, typically TypeScript/React/Node and/or Python, comfortable across the full stack and into infrastructure Uses AI tooling daily as part of how you actually build Comfortable with ambiguity and with being the person who decides Can talk to non-engineers about technical tradeoffs without losing either group Founding engineer experience is a plus, though this role won't carry the traditional founding-engineer scope of building and owning the whole system solo What Makes This Opportunity Different The product is category-defining. Investment banking has not been rebuilt around AI yet. This is the attempt to do it, not a feature layered onto something that already exists. You are early, but not too early. The MVP is nearly built, so you arrive with something real in hand rather than a blank page. You will build next to people who know the domain cold. Our partner has spent a career doing these deals. You will not be guessing at what bankers need or designing from secondhand assumptions. A high-autonomy team. You'll work alongside senior engineers who move fast and don't need hand-holding, with real say in the decisions that shape the product.
