About this role

**Location:** San Francisco Bay Area **Format:** In-office 4 days/week (flexibility for occasional remote days) ## Majordomo Mission Every generation of software creates a new operational layer—operating systems, cloud infrastructure, observability, and more. As production AI grows, teams are making daily decisions about evaluation, routing, latency, cost, and reliability, often by stitching together internal tooling. Majordomo believes production AI will depend on a **control plane**. The goal is to build that layer so engineering teams can **deploy, evaluate, and continuously improve** AI applications—without building the operational infrastructure themselves. Majordomo is a portfolio company of **super{set}**, a venture studio that conceives, funds, and builds AI-native companies from formation through scale. ## The Role (Cofounder) As a Cofounder, you’ll help build the company as much as the product—from early customer conversations and product direction to company building. You’ll move between **customers, product, and engineering**, turning customer insight into products developers choose to depend on. You’ll help decide **what we build, why it matters, and how we bring it to market**, collaborating with experienced builders who have spent two decades scaling enterprise infrastructure. Some days you’ll review architecture. Other days you’ll sit with customers to understand why they didn’t adopt something you expected them to. You won’t see these as separate jobs—just different parts of building products developers trust. ## Why This Role Matters Infrastructure products succeed when developers stop evaluating them and start **depending on** them. That trust is earned through many product decisions that rarely make release notes—an API that feels obvious, documentation that answers the next question, workflows that simplify, and customer conversations that reshape the roadmap. As a Cofounder, you’ll have an outsized influence on the decisions that will define the category and what developers come to expect from AI infrastructure. ## What You’ll Own - Product strategy, customer discovery, and technical go-to-market alongside the founding team - AI workflows that simplify how production systems are deployed, evaluated, and improved - Developer experience across APIs, documentation, and day-to-day workflows - Customer learning and translating conversations with design partners into product decisions - The quality bar across the product (architecture to interface design) - Developer adoption through products engineers recommend before anyone has to sell them ## What Success Looks Like (First 6–9 Months) - Established product direction customers consistently choose over building themselves - Built a repeatable design partner motion that shapes strategy and creates early advocates - Helped establish Majordomo’s product/technical/commercial foundation for scaling beyond the first release - Earned trust from engineers, customers, and the founding team as a product and company builder - Shipped capabilities that simplify operating production AI while earning developer trust - Created a culture where technical excellence, customer obsession, and speed of learning reinforce each other - Positioned Majordomo as a company developers recommend and design partners actively champion - Established operating rhythms that keep customer learning, product decisions, and company priorities aligned ## What You Bring ### Must Have - Natural d
