Low-level C++ Engineer (Blockchain)

Logos is a social movement and decentralised technology stack built to revitalise civil society.

The job:

You will design and implement liblogos, a modular plugin runtime for decentralised nodes, while optimising IPC, strengthening module isolation, fault-tolerance, scalability, and security. You will also collaborate with teams to build and test modules, like our Logos blockchain, messaging and storage modules.

Responsibilities:

• Help design and implement liblogos, which provides a modular plugin-based runtime for decentralized nodes and applications.
• Optimize IPC performance.
• Improve isolation (also in regards to efficiency), fault tolerance, independent scalability, and secure boundaries of modules to prevent cross-module vulnerabilities.
• Collaborate with component teams to build and test modules like decentralised nodes.

You ideally have:

• Proficiency in systems programming languages including C, C++, Rust, and Nim.
• Experience with plugin architectures, dynamic loading, and package managers for modular runtime systems.
• Strong understanding of microkernel principles: minimal core, service isolation, fault tolerance, and extensibility without core modifications.
• Experience with Linux namespaces and cgroups for process isolation, containerization techniques, and achieving microkernel-style separation in user-space environments.
• Knowledge of IPC optimization, and low-level performance tuning in multi-process environments.
• Experience in network programming.

Bonus points!

• Experience working for an open-source organization.
• Knowledge of type theory and programming language foundations.
• Experience with peer-to-peer technologies, blockchain, or cryptography.

Hiring Process:

• Intro Call with our POps team
• One or two technical interviews
• Home assignment
• Interview with co-founder

Compensation:

We are happy to pay in any mix of fiat/crypto.
