Decentralised Messaging Engineer
IFT
Role Description The Logos Messaging team is focused on creating communication infrastructure for a freer internet — permissionless, interoperable, and based on user consent. We're building toward a world where anyone can reach anyone on a network that no single entity controls or can take away. We cannot afford to compromise on Privacy, and "Eventual Decentralisation" is not an option. Right now we're deep in the hard problems: Bringing decentralised group messaging over MLS to all developers. This is frontier tech work — the protocols we're writing don't have established playbooks, and the tradeoffs we're navigating haven't all been mapped yet. This is where you come in. We're a small team seeking engineers who have a passion for decentralised chat and who've thought deeply about how these systems work, where they fail, and what it takes to get them right. You'll work directly on our SDK and contribute to the protocols underneath it, with real ownership over work that enables open communication. Qualifications - Deep familiarity with real-world instant messaging systems - you've worked on, contributed to, or spent serious time understanding how systems like Signal, Matrix, XMPP, or similar are built, where they make tradeoffs, and where they struggle. - Experience with decentralised computing - peer-to-peer systems, distributed networks, or decentralised application infrastructure. - Comfort working directly with cryptographic primitives - signatures, ciphers, and key exchanges and an understanding of secure private messaging principles such as forward secrecy, post-compromise security, and key management. - Solid Rust experience: comfortable writing reliable, maintainable code in a team setting. - Previous experience with Web3, blockchains, open protocols, and the values that underpin them. - A strong alignment to our principles: https://logos.co/manifesto/ Requirements - Implement our messaging protocols in our reference SDK, translating protocol specs into reliable, production-quality Rust. - Own the API design and developer experience of the SDK surface — abstractions, ergonomics, and developer-facing documentation. - Contribute to messaging protocol specifications alongside the team. - As a member of a small team, you'll wear many hats — picking up problems outside your immediate lane, learning as you go, and growing with the team. - Write clear technical documentation and participate in async design discussions with collaborators across the project. Bonus points - Experience with Post-Quantum Cryptography and its application to secure messaging. - Experience with MLS (Message Layer Security / RFC 9420) or the OpenMLS library specifically. - You've authored or contributed to an open specification. - Familiarity with P2P transport layers such as Waku or libp2p. - Experience working for an open source organisation. - Comfortable working remotely and asynchronously. Hiring process - Interview with our Talent team. - Interview with Team Member (Technical Life Story). - Interview with Team Lead / Pair Programming Session (Technical Discussion). - Interview with Program Lead (Culture Fit). Compensation The expected compensation range for this role is negotiable, dependent on how we assess your skills and experience throughout our interview process. We are happy to pay in any mix of fiat/crypto.

Role Description This role is for early-career engineers who want to become strong generalists by working on real systems. You will contribute across backend services, system reliability, testing, and release processes. The goal is not to specialize early, but to build a deep understanding of how production systems behave—and how to make them better. - Understand how systems work end-to-end - Identify where they fail - Improve them with increasing ownership over time This is not a ticket-taking role. You will be responsible for outcomes. What You Will Do - Build and improve backend services and APIs - Write automated tests and ensure system reliability - Debug issues across the stack (not just your code) - Improve CI/CD pipelines and release processes - Use LLM tools (Copilot, etc.) effectively to increase development velocity - Participate in production issue investigation and root cause analysis - Work with engineering and product to define clear, testable requirements - Contribute to how we measure system quality, reliability, and performance Qualifications - 1–3 years of experience building software (internships, projects, or self-directed work count) - Ability to write clean, working code in Python, JavaScript, or similar - Strong understanding of how systems work (APIs, data flow, failure modes) - High attention to detail and structured thinking - Evidence of ownership (projects you drove, not just contributed to) - Comfort using modern development tools, including LLM-assisted workflows Strong Signals - You have built and shipped something end-to-end (not just coursework) - You debug problems independently before asking for help - You think about edge cases, not just happy paths - You care about whether systems actually work in production - You use tools (including AI) to move faster without lowering standards What Success Looks Like - You identify issues before they reach customers - Systems you touch become more reliable over time - You move from guided execution → independent ownership - You improve not just code, but how the team builds and ships How We Work - Focus on a small number of important goals - Measure what matters and make it visible - Own outcomes, not just activity - Ship consistently and improve through discipline You will be expected to operate this way from day one. Who Should NOT Apply - You are looking for a purely remote role - You prefer clearly scoped tasks over ambiguous problems - You are not interested in understanding systems beyond your immediate work - You rely heavily on direction and struggle to operate independently - You are uncomfortable being measured on outcomes and system performance - You want to specialize narrowly early in your career Compensation - Competitive, market-aligned salary - Additional compensation and growth tied to performance and impact Why This Role This is an opportunity to build real engineering judgment early. You will work on systems used by financial institutions, learn how production systems behave under real constraints, and develop the ability to own and improve them. If you want to become a strong engineer by working on meaningful systems—and are willing to be held to a high standard—this is the environment to do it.
