The platform provides high-speed, low-cost, and energy-efficient transactions, empowering developers and institutions to launch scalable, real-world financial applications on-chain.

About the Role

As a C++ Engineer, you'll work on the distributed systems and consensus engine at the core of a global blockchain network used by developers and institutions worldwide.

This role involves tackling deep systems challenges

improving performance, optimizing peer-to-peer communication, ensuring security under adversarial conditions, and shaping the incentive mechanisms that drive decentralized stability and growth.

You'll join a team of experienced engineers collaborating on protocol evolution, consensus modeling, and system architecture making direct contributions to the foundation of next-generation blockchain infrastructure.

Key Responsibilities

• Design and build critical components of the blockchains core distributed system and consensus layer.
• Develop scalable, extensible, and secure infrastructure that powers thousands of on-chain applications.
• Collaborate with engineering leadership and community contributors on architectural design and protocol evolution.
• Write clean, maintainable, production-quality C++ code optimized for performance and reliability.
• Investigate and refactor performance bottlenecks across the system stack.
• Contribute to detailed technical specifications and RFCs, helping shape design standards for the engineering organization.
• Participate actively in code reviews and lead technical discussions on systems architecture and engineering best practices.

Required Qualifications

• 4+ years of professional software engineering experience.
• Bachelors or Masters degree in Computer Science or equivalent field.
• Deep, hands-on expertise in modern C++ (production-level experience required).
• Strong understanding of software design principles and patterns for modular, extensible systems.
• Proven ability to collaborate and communicate effectively in technical discussions and design reviews.
• Experience contributing to or developing in blockchain, distributed ledger, or decentralized protocol environments (or a demonstrated passion for the field through open-source projects, research, or personal initiatives).
