• 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.

2. 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.

3. 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.

4. 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.

2. 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.

3. 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.
