Demo Engineer - Venture Business

At Improbable, we build and scale ambitious AI and Web3 ventures shaping the next generation of the internet.

We’re hiring for a venture building a next-generation blockchain for real-time, large-scale applications, designed to overcome the speed and cost limitations of traditional blockchain infrastructure, the technology is fast, cost-efficient and fully EVM-compatible, enabling developers, creators and communities to build immersive products with greater ownership and interoperability.

About the Role

We’re hiring an Engineer to turn bold ideas into working demos that show developers what’s possible.

This is a hands-on role for someone who loves building and shipping fast. You’ll take concepts across DeFi, trading systems and agentic workflows, and turn them into live demos, prototypes and technical content that bring the technology to life and inspire developers to start building.

You’ll think independently, move quickly and create experiences that make complex technology feel clear, useful and exciting. If you use AI tools to accelerate how you think, build and deliver, you’ll thrive in this role.

What you’ll be doing

You’ll create the demos, prototypes and technical content that help developers and partners see what potentially can be built.

• Build demo dApps that bring the technology to life, from real-time trading interfaces and onchain games to agent-powered applications
• Create trading bot demos that highlight execution quality, onchain order books and new interaction models
• Prototype agentic applications, including autonomous agents coordinating onchain, prediction market resolvers and agent-to-agent workflows
• Produce video walkthroughs, live demos and coding content that make complex ideas easy to understand and exciting to explore
• Develop reusable starter kits, templates and reference projects that help developers start building faster
• Spot ecosystem trends early and turn them into timely, compelling demo ideas
• Partner with DevRel, Marketing and BD to support launches, partnerships and broader go-to-market activity

What we’re looking for

• Strong Solidity and EVM development experience, including writing, deploying and interacting with smart contracts
• Ability to build polished frontend interfaces for demos and prototypes
• A track record of turning ideas into working products, prototypes or experiments
• Strong instincts for what makes a demo memorable
• Comfortable working at speed and shipping rough but effective prototypes in days, not weeks
• High conviction, independent thinking and a bias toward action
• AI-native working habits, using tools to accelerate research, ideation, building and delivery

This role is ideal for someone who loves building in public, experimenting quickly and creating the proof points that get developers, partners and the wider ecosystem excited.

Apply if you want to build the demos people talk about.
