Iftother is hiring a

Senior Blockchain Systems Engineer (Protocol Architecture & Specification)

About Nimbus Nimbus is a research team that focuses on developing an Ethereum client and library. We believe that the largest deployment of Ethereum will potentially be on embedded systems and Nimbus is designed to perform well on embedded, mobile and generally resource-restricted devices. Building the stack from the ground up, we’re translating the latest Ethereum research into practical, performant and reusable libraries to provide a fertile exploration ground for further R&D.  About Nomos Nomos is a new blockchain designed from the ground up with the original cypherpunk ethos: decentralisation, censorship resistance, permissionless-ness and privacy. It will serve as the trustless agreements layer of the Logos stack. The forthcoming Nomos network will provide a common infrastructure layer upon which communities and aspiring network states can build social, governance, and financial services that uphold their community members’ fundamental rights and values.   The role & responsibilities: You will join the Nimbus team but work closely with Nomos to consume and provide feedback on specifications, ensuring a deep understanding of both projects. As a founding member of the Nimbus-Nomos team, you will also contribute to early architectural design and foundational decision-making. You will:

Develop a deep understanding of Nimbus and Nomos, including their architectures and designs. Consume specifications from Nomos and provide feedback where necessary.  Collaborate with the Nimbus team to address complex, non-incremental challenges in the specifications, rather than relying on scoping smaller tasks to learn the codebase. Participate in shaping the initial architecture and design principles of Nimbus-Nomos, aligning them with decentralisation, privacy, and censorship-resistance goals.

Requirements:

Strong understanding of blockchain technology and its underlying principles. Senior-level experience in the blockchain industry (several years), with a proven background in technical systems analysis and design. Technical background (Software Engineer or similar) and expertise in documentation, specification review, and architectural prototyping. You are proactive and communicative - making things happen comes easily to you. Commitment to privacy-focused, decentralised protocols and applications. Ability to work in early-stage, undefined environments where foundational contributions are critical.

NoteThis role may evolve to involve architectural input beyond specification review. While the current focus is on analysing specs, your involvement in early design decisions will be an expected and integral part of the position, not a surprise or additional responsibility. Bonus points:

Experience working in an open-source organisation. You've used Nimbus Client or have worked in a privacy-focused project/organisation.
