Job Description:

We are looking for a Protocol Engineer to join our team and work on blockchain infrastructure and protocol-level components. This role is aimed at engineers with real hands-on experience in core blockchain development, not only application-level work. We are looking for someone who understands how blockchain systems operate under the hood and has contributed to the architecture, implementation, or improvement of essential protocol components. You may be a strong fit if you have worked on nodes, validators, clients, execution or validation logic, synchronization, networking, storage, or other parts of blockchain infrastructure. We are especially interested in people who combine solid systems thinking with a practical engineering mindset and care about reliability, maintainability, and performance.

Job Responsibility:

Develop robust, scalable, and maintainable blockchain infrastructure and protocol-level components
Work on the implementation and improvement of core blockchain logic, including networking, validation, execution, synchronization, storage, or consensus-related systems
Participate in architecture discussions and help make technical decisions for complex distributed systems
Debug and resolve technical issues, identify bottlenecks, and implement effective solutions
Write tests, review code, and contribute to high engineering standards across the project
Collaborate closely with other engineers in a remote international team

Requirements:

Commercial experience in core blockchain development
Strong understanding of blockchain internals, such as consensus mechanisms, transaction lifecycle, mempool, block production and validation, P2P networking
Knowledge of cryptography fundamentals, including hashing, signatures, Merkle trees, and public/private key systems
Solid knowledge of distributed systems, concurrency, and performance-oriented backend development
Experience developing or maintaining protocol-level components, nodes, clients, validators, or other blockchain infrastructure
Experience with at least one system-level programming language such as Rust, Haskell, Go, C++, etc.
3+ years of professional software engineering experience
Strong grasp of computer science fundamentals, algorithms and data structures
Ability to work independently in a fully remote environment
Readiness to participate in code reviews and technical discussions
Care for code quality, reliability, and maintainability
Fluent spoken and written English

Nice to have:

Experience with peer-to-peer networking and low-level protocol design
Experience optimizing performance, throughput, or latency in distributed systems
Familiarity with smart contract platforms and virtual machine internals
Experience contributing to open-source blockchain projects

What we offer:

Competitive salary
Attractive international projects
Participation in the leading world conferences
International teams and multicultural environment
Fully remote work and flexible working hours
Possibility to take days off whenever you need
Investment in your professional and career growth, which will correspond to wage growth
Mentoring and training
Therapy sessions to support your well-being
Opportunity to contribute to one of the functional programming industry’s leading blogs
