Key Responsibilities
Design & Develop Next-Gen Crypto Products
Work within a high-performing global engineering team to design and implement next-generation blockchain-based applications. You’ll focus on building systems with performance, scalability, and continuous integration at their core — all while ensuring architectural consistency across services.
Build High-Availability Distributed Systems
Tackle complex engineering challenges by developing distributed services that operate at scale. Your solutions will need to meet strict requirements for uptime, speed, and fault tolerance — critical factors in the fast-moving world of cryptocurrency.
Collaborate Across Disciplines
Partner closely with design, product, and marketing teams to rapidly prototype and deploy new features. You’ll help translate innovative concepts into fully functional products that serve millions of users, requiring clear communication across technical and non-technical stakeholders.
Stay Ahead of Industry Trends
The blockchain space evolves rapidly. As part of your role, you’ll research emerging technologies, assess their applicability to our business needs, and quickly prototype promising solutions using the latest tools and frameworks.
Maintain Technical Excellence
Uphold best practices in software development through rigorous code reviews, comprehensive documentation, and efficient collaboration across time zones. You’ll contribute to a culture of quality, learning, and continuous improvement.
What We’re Looking For
To thrive in this role, you should possess a strong foundation in computer science or related disciplines, coupled with a genuine enthusiasm for blockchain technology. We welcome both formally educated candidates and self-taught innovators who demonstrate exceptional technical ability and curiosity.
Core Qualifications
- Bachelor’s degree in Computer Science, Cryptography, Blockchain Technology, Information Technology, Mathematics, or a related field (or equivalent experience as a self-taught developer)
Solid understanding of zero-knowledge proof (ZKP) theory and algorithms such as:
- zkSNARK
- zkSTARK
- PLONK
- Groth16
- Halo2
- Proficiency in at least one of the following programming languages: Java or Go
- Experience with Solidity and smart contract development
- Familiarity with Ethereum and other major blockchain networks
- Strong interest in blockchain technology with proven learning agility and problem-solving skills
- Ability to identify technical gaps and propose improvements to enhance workflow efficiency, test coverage, and solution quality
Why These Skills Matter
Zero-knowledge proofs are revolutionizing privacy and scalability in blockchain systems. By mastering these cryptographic tools, you’ll be equipped to build secure, trustless applications that push the boundaries of what’s possible in decentralized finance (DeFi), identity management, and beyond.
Proficiency in Go or Java ensures you can develop high-performance backend services, while Solidity expertise allows direct engagement with Ethereum-compatible smart contracts — foundational components of modern Web3 ecosystems.
