Role Description 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. - 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. Qualifications - 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. Requirements - 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.
