Software Engineer, Full Stack Developer, Front End Developer
At Blok, we’re building the simulation engine powering the next generation of adaptive software. Our multi-agent system predicts how different types of users will respond to digital experiences before any code is shipped. Product teams use Blok to simulate onboarding flows, test risky design changes, and de-risk product bets without waiting weeks for live traffic. We’re hiring a Front-End Engineer to take ownership of our customer-facing product UI.
You’ll work closely with our designers and backend team to rebuild the front-end layer on top of our simulation engine, ensuring the product is intuitive, performant, and ready to scale. This role is ideal for someone excited about complex state management, real-time data visualization, and building UIs that interact seamlessly with agent-based simulations.
