Who we are
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.
Our 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.
Assignment Description:
Joining us in Financial Services – Business Risk Services (FS BRS)
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.
If you’re an experienced Interim Tax 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.
As an Interim Tax Internal Auditor, you will be responsible for assessing governance, risk management and control frameworks across trading and tax-related functions, identifying control weaknesses, and providing practical recommendations to mitigate risk.
Skills we are looking for
· A strong background and significant experience in Internal Audit within Investment Banking or Capital Markets environments, with specific experience auditing Prime Finance businesses, including Delta One trading activities.
· Understanding of trading strategies, trading controls and associated tax risks
· Experience delivering audits covering Tax, Tax Risk Management, or related control frameworks.
· Knowledge of Markets, Trading Operations, Front Office Controls, and Regulatory Risk.
· Strong stakeholder management and report-writing skills.
· Experience within a major Investment Bank or Global Markets business is preferred.
· A professional qualification (ACA, ACCA, CIA, CFA or equivalent) is preferred.
· Previous exposure to regulatory reviews and complex trading environments is also preferred.
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.
