We’re looking for engineers who don’t just code—they innovate. Those who own their projects from end to end and constantly push for better performance, better architectures, better everything. Why This Role Is Exciting

Work with A-Players: Our engineering and research teams are some of the best in the space—prepare to level up by collaborating with them daily. Big Impact, Big Ownership: You’ll architect, build, and deploy systems that could redefine how people experience blockchain products. Cutting-Edge Tech: You won’t be stuck with legacy systems—expect a steady flow of new protocols, frameworks, and (optional) AI integrations to keep things fresh. Collaborative Culture: We take our work seriously—but we also believe in having fun, sharing memes, and celebrating each other’s wins.

What You’ll Be Doing 1. Fullstack Wizardry

Frontend Mastery: Craft high-performance, modern React (or similar) applications that delight users and scale smoothly. Backend Engineering: Design APIs (REST or GraphQL), optimize database interactions (SQL/NoSQL) and build robust cloud-native services.

1. Deep System & Algorithmic Design

Architect for Scale: Sketch out microservices, data pipelines, and other high-availability solutions that can grow with our user base. Optimize & Refine: Spot performance bottlenecks and kill them before they kill us.

1. Leadership & Collaboration

Code Reviews & Mentorship: Uphold high standards by giving and receiving thoughtful, constructive feedback. Cross-Functional Input: Work closely with product, design, and DevOps to ensure seamless rollouts and robust production systems. Innovation at the Core: Research emerging tech—especially blockchain protocols and AI—and propose how we can wield them.

1. Continuous Improvement

Experiment & Iterate: Pilot new tools, frameworks, or processes. If it makes us better, let’s do it. Own It End-to-End: From the first line of code to the final deploy, you’re responsible for delivering secure, stable, and high-quality solutions.

What We’re Looking For 1. Proven Experience

Multiple Years in professional software development. You’ve tackled complex, large-scale projects and thrived. Fullstack Expertise: From writing impeccable React components to designing backends in Node.js, GO, Rust or Python.

1. Technical Chops

System Design & Architecture: You know how to build services that won’t break under pressure—microservices, caching strategies, database sharding, you name it. Performance Focus: Terms like “high throughput” and “low latency” aren’t just buzzwords to you; they’re part of your daily vocabulary. Best Practices: You never skip tests, you don’t do “quick hacks,” and you treat CI/CD pipelines like your best friend.

1. Mindset & Soft Skills

Ownership & Drive: You see problems and can’t help but fix them. Team Player: You communicate clearly, listen actively, and love a good brainstorming session. Always Growing: You stay up-to-date with tech trends and are curious about areas like blockchain, AI or Quantum computing.

Bonus Points For

Blockchain Know-How: Familiarity with smart contracts, DeFi protocols, or web3 libraries. AI Curiosity: Even if it’s just side projects or tinkering with AI agents, we love that forward-thinking spirit. Small Team Leadership: If you’ve led a tight-knit group of devs, share those stories!

What’s in It for You

Serious Impact: Your code and ideas will shape next-gen decentralized solutions used by an ever-growing community. Learning on Steroids: Our projects span everything from cutting-edge blockchains to AI enhancements—there’s always something new to dive into. Flexible & Remote: We trust you to do your best work from wherever you are, on your own schedule. Top-Notch Compensation: We offer a competitive salary + potential for equity—because top talent deserves top rewards.
