About the role
Are you ready to shape the future of capital markets? We are looking for a hands-on Head of Engineering
- Digital Assets to own our technical architecture, set the engineering bar, and lead the build as a player-coach. You will join the CEDS Digital Asset team. The position will be based in Paris, and start as soon as possible. You will report to the CTO Digital Assets.## About the missionYou will architect the platform behind Euronext’s first tokenised offerings. The role spans two live programmes already in design:
* A 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.
* A tokenised collateral-management platform for sovereign bonds, enabling real-time repo, CCP-margin eligibility and DeFi distribution of govies through gated lending venues.
Both 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.## What you’ll do
* Own end-to-end architecture for digital asset solutions, combining distributed ledger technology (DLT) with traditional market infrastructure (trading, clearing, settlement, custody and CSD).
* Designing cross-chain topology — permissioned chains for the institutional/CCP side (Hyperledger Besu, Canton Network candidates) and public chains for DeFi distribution (Ethereum / L2).
* Defining 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).
* Architecting 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.
* Set standards for code, review, testing, and secure-by-design delivery.
* Lead threat modelling and security architecture until a dedicated security lead is in place.
* Plan and lead the evolution of the team as products move from build to run.
* Make build/buy/partner decisions on chain, custody, and audit with Product.
* Collaborating 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).
* Stay hands-on in incidents and on the highest-risk components.## What you bring
* Deep distributed-systems and DLT architecture experience; fluency with EVM and permissioned chains (e.g. Canton, Besu).
* Hands-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.
* Proven secure-architecture and threat-modelling skills for high-value financial systems operating 24x7 with zero downtime.
* Working knowledge of capital-markets settlement (delivery-versus-payment, CSD, CCP/clearing) sufficient to design integrations.
* Player-coach leadership; decisive and calm under pressure.
* Excellent communication and stakeholder-management skills, comfortable bridging engineering, business, legal and regulatory audiences.
* Minimum seven years of experience in solution architecture, including at least three years in DLT or blockchain projects.
* Degree in computer science, engineering or related field; certifications in cloud or blockchain technologies are a plus.## AI engineering skills (required)
* Define 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).
* Set guardrails for AI-assisted code: review gates, secret and prompt hygiene, and licence/provenance checks on generated code.
* Evaluate and select AI tooling; judge where productivity gains are real.
* Able to specify AI-in-product capabilities (e.g. anomaly detection, operational triage) and their risk controls.## Join Euronext – Shape capital markets for future generationsJoin a company where market infrastructure is built on innovation — and where every innovation starts with a bold mind asking, “What’s next?”.
