Logos • Full-time • Remote • 3h ago

Logos is a movement supporting the development of the decentralised web. Logos technologies lay the foundations for a freer internet upon which communities can evolve into network states. Each protocol in the Logos stack seeks to empower its users while upholding civil liberties and fundamental freedoms.

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.
