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.
