About the Role: OSTTRA - HEAD OF TAX OSTTRA are a leading provider of post-trade solutions for the global OTC market.

The Head of Tax will have overall responsibility for all Corporate Tax activities across the group including compliance, reporting and transfer pricing with a focus on maximising value for our Shareholders. OSTTRA has 30 entities across multiple geographical jurisdictions, with key locations located in UK, US, Sweden, India, Singapore and Malaysia together with several other global locations and as such you should be able to navigate complex, often conflicting, tax landscapes, managing compliance, and contribute to strategic tax planning, particularly within the context of our Shareholder's Investment Strategies. You will be required to oversee the current outsource providers (PWC) as OSTTRA carves its business out from the current TSA relationship with S&P into a new standalone framework. We are looking for someone with a proven track record of working in a changing environment, who has experience of working internationally ideally, (but not essentially) within either PE or a regulated business. The role is based in our London office near Liverpool Street Station, with a minimum 3 days a week in office (although contract does say 5 days). There is no prescribed overseas travel requirement, however candidates must be able to travel as required in the performance of their duties.

Specific Context for OSTTRA: • Leveraged Experience: Understanding the tax implications of a leveraged business, including debt structure, interest deductibility, and the resulting impacts on cash flow and marginal tax rates. • Mergers, Acquisitions and Partnerships: Providing tax advice on the structuring of acquisitions and divestitures, including VAT implications and tax planning for integration. • Investment Strategies: Working with the CFO to develop tax-efficient investment strategies for the Shareholders. • Global Tax Implications: Managing tax risks and opportunities in a global context, particularly in the context of cross-border operations as well as Partnerships and M&A. This is a critical role requiring a combination of technical expertise, strategic thinking, and strong leadership skills to navigate the complexities of our multinational organisation in order to maximise value for OSTTRA and our Shareholders. The ability to adapt and work in a fast-paced, dynamic environment as we undergo a period of significant change will require flexibility and adaptability.
