The platform spans a sequencer and coordinator, a ZK proving stack, cross-ledger interoperability, privacy and settlement components, and the infrastructure that runs all of it in production for clients with contractual commitments.\nSomeone has to hold that whole picture and make the pieces fit. Not in a diagram - in the code, in the design decisions, and in the answers we give institutional architects who are deciding whether to put real value on our networks.\nThis is a hands-on role. You will write code, build proofs of concept, and be in the design reviews. If you haven't shipped something yourself in the last year, this isn't the right role.\nWhat you'll own\nArchitecture across the platform - how the sequencer, coordinator, proving stack, interop layer, privacy components and infrastructure fit together, and where the seams are.\n\nCross-ledger interoperability architecture. This is our differentiator and our IP, not a commodity - the design choices here decide what we can sell and what we can charge for.\n\nTurning institutional requirements into designs. Our clients issue detailed requirement documents - availability, finality, privacy isolation, RBAC, key custody, emergency deployment. You turn those into architecture the team can build and we can evidence, and you are honest about which requirements we meet technically and which we meet by control and attestation.\n\nProofs of concept. Built by you in partnership with the Engineering team, after specified to a high quality by you. Ambiguity gets resolved by building the smallest real thing.\n\nDesign reviews and architecture decisions - written down, with the reasoning and the discarded options, so the next person doesn't re-litigate them.\n\nBuild versus buy. Where we take a third-party component, where we build, and what that costs us in dependency.\n\nTechnical depth in client and partner deep-dives when the conversation goes past what a slide can carry.\n\nArchitecture decisions are final. You time-box spikes and PoCs, you write down the discarded path, and you freeze the call so engineering is not implementing two designs at once.\n\nYou own the design so other people can build. That means interfaces, constraints and written decisions - not sitting in every review. Teams should be able to ship against an Architecture Decision Record without you in the room.\n\nYou use AI daily to explore designs, write and test PoCs and draft ADRs. You set that practice for the people who implement your designs.\n\nDesigns that survive production. Availability, finality, rollback and proving upgrades are architecture constraints, not an ops surprise after merge.\n\nHow this fits\nProduct - you pair closely with Product on what we build and why. Architecture that isn't anchored in a client problem is a hobby.\n\nCryptography and ZK research (prover, zkEVM, arithmetization) - a separate line. Their output is a major input to your architecture; you need enough depth to reason about proving costs, latency and constraints without needing to be a cryptographer.\n\nCore protocols (Besu, Teku and related clients) - sits with our Head of Protocols. Client capabilities and roadmap commitments there shape what you can design.\n\nEngineering and infrastructure - your designs are built and operated by these teams. They will tell you quickly if a design doesn't survive contact with production, and you should want them to.\n\nWhat we are looking for\nHas designed distributed systems and built them - recent, hands-on, in a language we use (Kotlin, Go, Rust, Solidity, TypeScript, Zig).\n\nHas strong hands-on background of Software Development/Engineering, 8+ years.\n\nCan hold a large system in their head and see where it doesn't fit together, and reason down to detailed technical level- the failure modes, the coupling, the thing that breaks at scale-and be able to effectively communicate this to colleagues.\n\nEthereum and EVM knowledge, or the demonstrated ability to get there fast from adjacent distributed-systems work.\n\nWrites clearly. Design documents and diagrams that a bank's architecture team will accept without a meeting. Not just for external, but for internal too. The architect should leave behind clear written artifacts that make it clear what engineers need to build and why, and what success looks like.\n\nCan be in a room with institutional architects and stay technical - credible on resilience, key custody, finality and privacy without drifting into sales language.\n\nPragmatic. Knows when the right architecture is the boring one.\n\nDecisive under ambiguity. Makes the call when Product, a client requirement and a protocol constraint disagree.\n\nExperience architecting for secure mission-critical systems.\n\nUseful, not required\nZK proof systems - enough to reason about cost, latency and trust assumptions.\n\nPrivacy technologies: privacy pools, MPC, trusted execution, tokenisation frameworks.\n\nRegulated financial infrastructure - payments, clearing, settlement, custody.\n\nUnderstanding of governance dynamics and key stakeholders within the Ethereum ecosystem.\n\nExperience of cloud and infra deployments and topologies.\n\nExperience in Fintech/Banking/Trading or similar domains.\n\nWhat this role is not\nNot a PowerPoint architect. If the last two years of your work are diagrams and decks, this is the wrong role and the interview will find that out.\n\nNot a pre-sales function. You'll join client technical sessions, but delivery is the job.\n\nNot a people-management role. This is an individual contributor position with real technical authority.\n\nWorking at Consensys\nWe are a fully remote, globally distributed company. We hire the best people wherever they are, work asynchronously, and judge each other on impact rather than hours or location. We offer competitive compensation, meaningful equity, and the chance to work on genuinely open source software at the frontier of web3.\nConsensys is an equal opportunities employer. We celebrate diversity and are committed to building an inclusive environment for all employees.","description_format":"text","description_chars":6957,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Germany","iso":"DE","kind":"region"},{"name":"France","iso":"FR","kind":"region"},{"name":"United Kingdom","iso":"GB","kind":"region"},{"name":"Austria","iso":"AT","kind":"region"},{"name":"Belgium","iso":"BE","kind":"region"},{"name":"Bulgaria","iso":"BG","kind":"region"},{"name":"Croatia","iso":"HR","kind":"region"},{"name":"Czech Republic","iso":"CZ","kind":"region"},{"name":"Denmark","iso":"DK","kind":"region"},{"name":"Finland","iso":"FI","kind":"region"},{"name":"Hungary","iso":"HU","kind":"region"},{"name":"Ireland","iso":"IE","kind":"region"},{"name":"Italy","iso":"IT","kind":"region"},{"name":"Netherlands","iso":"NL","kind":"region"},{"name":"Norway","iso":"NO","kind":"region"},{"name":"Poland","iso":"PL","kind":"region"},{"name":"Romania","iso":"RO","kind":"region"},{"name":"Spain","iso":"ES","kind":"region"},{"name":"Sweden","iso":"SE","kind":"region"},{"name":"Switzerland","iso":"CH","kind":"region"},{"name":"Estonia","iso":"EE","kind":"region"},{"name":"Greece","iso":"GR","kind":"region"},{"name":"Iceland","iso":"IS","kind":"region"},{"name":"Latvia","iso":"LV","kind":"region"},{"name":"Liechtenstein","iso":"LI","kind":"region"},{"name":"Lithuania","iso":"LT","kind":"region"},{"name":"Luxembourg","iso":"LU","kind":"region"},{"name":"Malta","iso":"MT","kind":"region"},{"name":"Portugal","iso":"PT","kind":"region"},{"name":"Slovakia","iso":"SK","kind":"region"},{"name":"Slovenia","iso":"SI","kind":"region"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cryptocurrencies","Blockchain Infrastructure","Asset Tokenization"],"lifecycle":[{"event":"open","at":"2026-09-28T08:50:07Z"},{"event":"close","at":"2026-10-11T22:45:02Z"},{"event":"reopen","at":"2026-10-14T05:09:25Z"}],"visa":[],"liveness":{"score":36,"band":"fade","label":"Fading","p_open":1,"p_active":0.799,"p_room":0.45,"age_days":29,"expected_fill_days":18,"reasons":["conf:3","velocity","win:tail"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/ethereal-news-software-systems-architect","json_url":"https://alion.io/job/ethereal-news-software-systems-architect.json","meta":{"generated_at":"2026-10-23T08:16:32Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":13169,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3875570},"rest":"https://alion.io/mcp/rest/get_company?id=3875570"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fethereal-news-software-systems-architect"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fethereal-news-software-systems-architect"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fethereal-news-software-systems-architect"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/ethereal-news-software-systems-architect\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fethereal-news-software-systems-architect"}]}
