The role spans two live programmes already in design:\nA tokenised issuance, trading and settlement platform (equities, ETFs and bonds), with a 24/7 central limit order book, fractional trading, CCP-cleared trades and end-of-day atomic DvP settlement on chain.\nA tokenised collateral-management platform for sovereign bonds, enabling real-time repo, CCP-margin eligibility and DeFi distribution of govies through gated lending venues.\nBoth are built on the same conviction: the token is the financial instrument (no wrapper), one ISIN means one ledger, and the CSD drives tokenisation. You will turn these principles into a concrete, secure and auditable architecture.\nWhat you’ll do\nOwn end-to-end architecture for digital asset solutions, combining distributed ledger technology (DLT) with traditional market infrastructure (trading, clearing, settlement, custody and CSD).\nDesigning cross-chain topology - permissioned chains for the institutional/CCP side (Hyperledger Besu, Canton Network candidates) and public chains for DeFi distribution (Ethereum / L2).\nDefining the on-chain compliance model: regulated security-token standards (ERC-3643 / T-REX), KYC-whitelisted wallets, on-chain transfer restrictions, AML screening on every transfer (Chainalysis / Elliptic) and transaction reporting (MiFIR).\nArchitecting custody and key management around MPC solutions (Fireblocks, Taurus candidates), including a hybrid model that supports bring-your-own-custody for institutions that require it.\nSet standards for code, review, testing, and secure-by-design delivery.\nLead threat modelling and security architecture until a dedicated security lead is in place.\nPlan and lead the evolution of the team as products move from build to run.\nMake build/buy/partner decisions on chain, custody, and audit with Product.\nCollaborating with cross-functional teams - product, legal, regulatory, clearing, CSD and client working groups - to ensure alignment with business objectives and the evolving regulatory framework (DLT Pilot Regime, MiFID II, MiCA).\nStay hands-on in incidents and on the highest-risk components.\nWhat you bring\nDeep distributed-systems and DLT architecture experience; fluency with EVM and permissioned chains (e.g. Canton, Besu).\nHands-on understanding of token standards for regulated securities (ERC-3643 / T-REX or equivalent), on-chain compliance, and the security pitfalls of smart contracts and cross-chain bridges.\nProven secure-architecture and threat-modelling skills for high-value financial systems operating 24x7 with zero downtime.\nWorking knowledge of capital-markets settlement (delivery-versus-payment, CSD, CCP/clearing) sufficient to design integrations.\nPlayer-coach leadership; decisive and calm under pressure.\nExcellent communication and stakeholder-management skills, comfortable bridging engineering, business, legal and regulatory audiences.\nMinimum seven years of experience in solution architecture, including at least three years in DLT or blockchain projects.\nDegree in computer science, engineering or related field; certifications in cloud or blockchain technologies are a plus.\nAI engineering skills (required)\nDefine and lead an AI-augmented software-delivery process: coding assistants, smart-contract scaffolding, AI-generated test suites - and a clear view of where AI must not be relied on (security and risk sign-off).\nSet guardrails for AI-assisted code: review gates, secret and prompt hygiene, and licence/provenance checks on generated code.\nEvaluate and select AI tooling; judge where productivity gains are real.\nAble to specify AI-in-product capabilities (e.g. anomaly detection, operational triage) and their risk controls.\nJoin Euronext - Shape capital markets for future generations\nJoin a company where market infrastructure is built on innovation - and where every innovation starts with a bold mind asking, “What’s next?”.
