Interim Digital Assets & DLT Internal Auditor in London

At Grant Thornton we’re building something bold. We’re doing things differently - looking to the future, driving ambitious growth and pioneering positive change in our industry. Providing audit, tax and advisory services, we empower clients through strategic insight, curiosity, and genuine partnership. And we empower our people with real opportunity. Our journey from great to exceptional is well underway. With significant investment behind us and a clear strategy for growth, there’s real momentum.

Agile Talent Community (ATC) brings together experienced contract professionals who want choice without losing connection. You work where you add the most value, alongside teams who treat you as a partner rather than a placeholder.

Grant Thornton’s Financial Services Business Risk Services (FS BRS) team delivers market-leading risk, control and governance services to clients across insurance, banking and investment management. We work alongside financial institutions to help them achieve their strategic goals – whether that means navigating new legislation, responding to regulatory change, or adapting their technology and operating models to stay competitive in a rapidly evolving landscape.

Our work spans internal audit (outsource and co-source), finance and risk management, compliance and technology – giving our people broad exposure to some of the most complex and high‑profile challenges in financial services today.

For an experienced Interim Digital Assets & DLT Internal Auditor who’s tired of choosing between freedom and meaningful work, there’s another route. Within our FS BRS team, you’ll be given the opportunity to take on short‑to‑medium‑term projects that sharpen your expertise, stretch your thinking, and give you a different angle on familiar challenges - all without locking you into a single path.

Skills we are looking for:

• Strong understanding of digital asset ecosystems, including cryptocurrencies, stablecoins and tokenisation, and their practical application within financial services institutions across custody, trading, settlement and post‑trade operations.
• Proven experience leading complex internal audit engagements with direct and substantive exposure to digital assets and/or distributed ledger technology across the full engagement lifecycle.
• Solid knowledge of risk management and governance frameworks applicable to digital asset product lifecycles, including new activity approval processes, the identification of heightened risks, and the design, implementation and evaluation of control frameworks.
• In‑depth technical knowledge of DLT infrastructure and digital custody solutions, including multi‑party computation (MPC), hardware security modules (HSMs), cold/hot storage architectures, smart contract security, tokenisation lifecycles (minting, burning, transfer), and blockchain node and cryptographic key management.
• Proven experience assessing cybersecurity and technical risk within a DLT environment, including threat modelling across complex platform architectures, vulnerability and privileged access management (PAM), and the evaluation of security operations capabilities such as SIEM, intrusion detection (IDS), and endpoint detection and response (EDR).
• Demonstrable experience working with blockchain analytics and forensic tools, with a sound understanding of their application to AML/CFT obligations, transaction monitoring programmes and on‑chain investigations within a regulated financial services context.
• Strong track record evaluating risks associated with third‑party blockchain infrastructure, cross‑chain interoperability protocols (bridges) and smart contract audit processes, including the assessment of automated on‑chain settlement workflows such as Delivery versus Payment (DvP) and Payment versus Payment (PvP).

Why Consultants choose the ATC:

• Work that moves you forward: When a project fits your skills, we’ll get in touch, but you choose whether it’s right for you. That means working on engagements that genuinely build your portfolio and expand your expertise.
• The freedom of contracting without the hidden admin: You’re not left to navigate the freelance world alone. Our Agile Talent team helps you understand freelance regulation and connects you with people who broaden your thinking through our teams and clients.
• Community you can actually feel: Connection shouldn’t disappear just because you’re contracting. From market insights to wellbeing sessions to networking events, you’ll be part of a community designed to make the independent path less isolated and more impactful.

Our culture and values:

We have a culture where talented people thrive – where high performance is not just expected but enabled. It’s a culture built on clarity, curiosity, and care. One that challenges us to aim higher, where we’re encouraged to make the most of an abundance of resources to fuel our own development, and where we support each other to grow, learn, and succeed.

Our open and accessible culture means you’ll interact with leaders who are interested in you and everything you bring to our firm. The things that set you apart, we value them. That’s why we give you the freedom to bring your whole self to work and pursue your passions inside and outside of work.
