What are we all about?

We are a team of builders and researchers on a mission to empower enterprises and developers worldwide to access and build on decentralized systems.

Our expertise covers several domains: Ethereum and Starknet protocol engineering, layer-2, AI, cryptography research, protocol research, decentralized finance (DeFi), security auditing, formal verification, real-time monitoring, smart contract development, and dapps and enterprise engineering.

Working to solve some of the most challenging problems in the blockchain space, we frequently collaborate with renowned companies, such as Ethereum Foundation, Starknet Foundation, Gnosis Chain, Flashbots, Forta Protocol, Lido, EigenLayer, Open Zeppelin, RISCZero, Aleph Zero, and many more.

Today, we are a 350+ strong team working remotely across 66+ countries.

*How to Know If You’re the Right Fit

If you live for deep, mind-bending problems and take pride in building both slick frontends and rock-solid backends, keep reading. 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.

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 e 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.
