About Us
We are an AI & Blockchain company building the financial infrastructure for the AI age. We have customers in 19 countries, and our team is an international mix of remote talents with two core locations in Singapore and Dubai.
We raised $2.8M in funding and are expanding our team, with new products across SaaS and retail. By joining now, you’ll have the unique opportunity to work directly with founders who have made multiple exits, and build the future of AI and finance.
About You
You are a full-stack product engineer who can turn ideas into products from 0 to 1, using modern agentic coding tools without losing engineering judgment. This is not a simple vibe-coding role. You need to know how to code, reason about systems, identify poor abstractions, avoid AI-generated slop, and ship software that is readable, maintainable, and useful. You should be able to sit with a product idea, identify the core user flow, design the first version, build the front end, wire up the back end, leverage AI tools aggressively, and still have the engineering judgment to know when the code is wrong.
Your Profile
Full-stack engineer with real product taste.
AI-native, but not AI-dependent.
Comfortable shipping across front end, back end, database, infra, and third-party APIs.
Able to use coding agents deeply while maintaining control over architecture and quality.
Good at detecting slop: messy code, fake abstractions, weak tests, security gaps, bad UX, and hidden complexity.
Independent, fast, curious, and comfortable with ambiguity.
Your Work
Build products and tools from scratch.
Use AI coding tools to materially increase shipping speed.
Work across React/Next.js, Node/Python, databases, APIs, authentication, cloud platforms, and similar technologies.
Turn product ideas and UX concepts into useful software with minimal direction.
