StellenbeschreibungLuxium AG in Zug, Switzerland is building a new Layer 1 blockchain from first principles, with a post quantum cryptographic core rather than a retrofit of classical primitives. We seek a full time Chief Blockchain Architect to own the protocol design and its long term technical direction. The work opens with an architecture phase: set the protocol foundations and write the specification the engineering team builds against then lead the technical organization, working directly with the founders. Two main elements are specific to this system, an on chain price formation mechanism inside the protocol, and Luxium Nation, a global network with governance and payment layers on the same token. Scope Design the core architecture: consensus, validator model, network layer, state model and execution environment. Select and justify the cryptographic primitives, including signatures, hashes, commitments and key management, with attention to quantum resistance and migration paths. State and defend the security model: adversary and network assumptions, safety and liveness arguments, and the trade offs between scalability, security and decentralization. Produce rigorous specifications and identify technical risk. We want depth in distributed systems, consensus and their cryptography, the ability to architect from first principles rather than assemble components, and strong technical writing. Valued: prior Layer 1 design or production consensus work; publications in cryptology or distributed computing; open source contributions; post quantum constructions; systems level implementation (Rust, Go, C++ or comparable). Relocation to Zug is required and fully supported. If that is not possible for you, say so and we will discuss it. Compensation is negotiated individually and may combine salary, incentives, equity and token participation.
