About Us NeoSigma is a product-driven research lab building the intelligence layer that helps close the feedback loop between your customers, products, and AI systems. We are a small, intensely technical team of researchers and engineers who have trained frontier-scale models and widely used AI products and agents at MIT, Parallel Web, Essential AI, Apple, and Amazon. The Role We are looking for a Founding Business Generalist to help build NeoSigma alongside the founders. You will work across customers, product, GTM, strategy, and business operations, with a strong bias toward execution. We're looking for someone who understands technology deeply but is most energized operating at the intersection of business, product, and customers. You'll help shape the company from the ground up, tackling high-impact, ambiguous challenges across a broad scope in a fast moving environment. What you'll do • Own high-priority workflows across sales, pricing, contracts, growth, and company operations. • Move customer opportunities from initial research and discovery through proposals, pilots, procurement, and close. • Turn customer conversations into sharper product, positioning, pricing, and company strategy. • Research unfamiliar markets and business problems, develop clear recommendations, and drive them through execution. • Run rapid experiments across outbound, content, partnerships, pricing, and new markets. • Build lightweight systems, automations, and operating processes that create leverage for the founders and the broader team. What we look for • Extremely high agency. You create structure, move fast, and do not wait for instructions. • Strong technical fluency. You understand complex technology and are energized by operating at the interface of product, customers, and the market. • Sharp commercial and product instincts, with the ability to translate technical capabilities into clear customer value. • Exceptional research, writing, and communication skills, with the judgment to turn ambiguous information into action. • Comfort moving between strategy and hands-on execution, whether preparing a customer proposal, researching pricing, coordinating a contract, or shaping a product decision. • Experience as a founder, early-stage operator, or investor is a strong plus. Our Core Values • Customer Obsession - We start with the customer and work backwards. We aim to earn trust through consistent delivery, thoughtful listening, and by obsessing over customers. • Intellectual Honesty - We operate with high trust and low ego. Ideas matter more than titles, and we communicate openly and directly while assuming good intent, even in strong disagreement. • Bias for Action - We set high standards and move quickly to meet them. We prefer building and learning with customers over debating in the abstract, and we iterate based on real feedback. • Extreme Ownership - We take responsibility for outcomes, not just tasks. Ownership means seeing problems through to completion and ensuring solutions truly work in practice. Benefits and perks • Competitive salary plus meaningful equity package • Comprehensive medical benefits and generous PTO • Flexible work arrangements • Direct impact on company direction and technical decisions • High ownership and the opportunity to make a career-defining impact • Visa sponsorship As a founding member, you’ll help define the technical foundation of NeoSigma. Your scope will grow with the company, from owning core systems end-to-end to shaping architecture, hiring, and engineering culture. This role has a natural path toward technical leadership or engineering management as the team scales.
