Senior Full-Stack Engineer Engineering

We're hiring a Senior Full-Stack Engineer as one of our first engineering hires. You'll work across our TypeScript monorepo (30+ event-driven microservices) and Next.js webapp, owning features from concept to production.Prediction markets are one of the most accurate forecasting tools ever invented, but they've been locked behind clunky interfaces and regulatory barriers. We're changing that.Kash lets anyone create and use prediction markets directly through social platforms. See a debate on Twitter? Create a market. Want to make a prediction with your take? Post it. AI handles market creation and resolution, users just interact naturally.Twitter is live. More are coming. We're a small, high-intensity team building at the intersection of social, crypto, and AI.The TeamWe're a small founding team with backgrounds at hedgefunds, investment banks and more.We've built and scaled ecosystems, shipped DeFi security research, and designed products used everyday.We know what we're doing, and we're looking for engineers who do too.The RoleWe're hiring a Senior Full-Stack Engineer as one of our first engineering hires. You'll work across our TypeScript monorepo (30+ event-driven microservices) and Next.js webapp, owning features from concept to production.This isn't a cog-in-the-machine role. You'll have real ownership, direct impact, and the autonomy to make decisions. We move fast, but we care about craft. Quality matters.AI-driven development is non-negotiable.
