AI-Native Full-Stack Product Engineer
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.
Chief Technology Officer (CTO) / Senior Full-Stack Developer (Web3)
We are building a next-generation Web3 social platform designed to redefine how digital communities connect, collaborate, and grow.
Backed by years of experience within the cryptocurrency, blockchain, and digital asset ecosystem, our team has developed deep insights into how founders, developers, investors, creators, and communities interact. This understanding inspired us to create a platform that goes beyond financial applications and focuses on empowering meaningful social engagement.
Our mission is to build a transparent, community-driven social network where users can share ideas, collaborate on projects, discover opportunities, and create lasting relationships. We believe the next evolution of social media will be powered by decentralized technologies while maintaining an exceptional user experience, simplicity, and long-term sustainability.
We are seeking an experienced Chief Technology Officer (CTO) or Senior Full-Stack Developer who is passionate about Web3 and capable of leading the technical vision, architecture, and execution of our platform from the ground up.
Responsibilities

Design and build scalable backend systems and modern frontend applications.
Develop high-performance APIs and real-time features.
Integrate blockchain technologies, wallets, and Web3 authentication where appropriate.
Build secure, reliable, and maintainable infrastructure.
Collaborate closely with product, design, and leadership teams.
Establish engineering best practices, code quality standards, and development workflows.
Mentor engineers and help grow the technical organization.
Evaluate emerging technologies and implement solutions that improve scalability, security, and user experience.
Requirements
5+ years of professional software development experience.
Strong experience with modern JavaScript/TypeScript ecosystems.
Experience with React, Next.js, Node.js, or similar technologies.
Solid understanding of system architecture, cloud infrastructure, databases, and API design.
Experience building scalable consumer-facing products.
Familiarity with blockchain technologies, Web3 infrastructure, wallets, smart contracts, or decentralized applications.
Strong knowledge of security best practices and application performance optimization.
Excellent problem-solving and communication skills.
Ability to work independently in a fast-paced startup environment.
Preferred Qualifications
Experience building Web3 or crypto products.
Understanding of decentralized identity, token ecosystems, or on-chain social applications.
Experience leading engineering teams or serving in a technical leadership role.
Background in DevOps, CI/CD, Docker, Kubernetes, or cloud platforms such as AWS or GCP.
Experience with real-time messaging, social platforms, or community products.
What We Offer
Competitive full-time compensation.
Opportunity to build a product from an early stage with significant technical ownership.
Flexible and remote-friendly work environment.
Collaborative team focused on innovation and long-term impact.
Work on cutting-edge Web3 technologies and help shape the future of digital communities.
Opportunity for career growth and leadership as the platform scales.
If you are excited about building the next generation of Web3 social experiences and want to make a meaningful impact from the earliest stages, we'd love to hear from you.
