About Mercuria

Established in 2004, Mercuria is one of the leading integrated energy and commodity trading companies in the world. We bring energy markets together to support the needs of today by trading, structuring finance, and investing into strategic assets, while generating more than $110 billion in turnover.

Our operations span over 50 countries on 5 continents, including all the major energy hubs. We trade physical oil, energy products, environmental products and other commodities from Geneva, London, Singapore, Shanghai, Beijing, Dubai, Houston, Calgary and Greenwich (CT).

We are committed to advancing the transition to a more sustainable, affordable and reliable energy system for tomorrow. Over 50% of our assets are in low carbon & energy transition sectors - providing a strong platform to trade these new markets and support decarbonization.

In 2023, we established Silvania, a $500 million fund, investing into restoration and protection of nature and biodiversity globally and in support of the Paris Agreement goals & UN 30x30 biodiversity initiative. This new asset class supports nature protection and provides sustainable financial returns.

Our role

You will join Mercuria's direct tax team in Rotterdam, working closely with our International Tax Manager and our Head of Tax Compliance & Technology.

The role covers a broad range of compliance, reporting and technology-driven work, with real ownership from day one.

Technology is not a separate workstream here. It runs through everything the team does, from how returns are prepared to how management is informed. You will be part of building this, not just using it.

Compliance & Reporting

• Working closely with senior regional tax staff and external advisers to ensure timely filing of the Group's global tax returns and payments
• Supporting and preparing responses to enquiries and tax audits across foreign jurisdictions

Tax Accounting

• Supporting the tax accounting cycle (periodic tax provisioning, current and deferred tax calculations, and balance sheet management)
• Liaising with statutory auditors at closing

Reporting & Commercial Projects

• Contributing to tax management reporting in close collaboration with Geneva headquarters
• Participating in commercial projects including group restructurings, acquisitions and disposals

Technology & Innovation

• Contributing to tax technology initiatives (working with data outputs and dashboards, helping automate and improve compliance workflows)
• Participating in AI-assisted analysis of intercompany positions and fiscal reporting
• Working with data pipelines and dashboards that feed real-time fiscal insight to management

What We Are Looking For

We are looking for candidates ranging from an ambitious professional ready to take on real responsibility to a more seasoned specialist looking for a broader platform.

What matters most is not the number of years, but the combination of solid fiscal grounding, a collaborative mindset and genuine curiosity about where the tax profession is heading.

Requirements

• Excellent proficiency in Dutch and English
• 3–6 years of relevant corporate tax experience at a tax advisory firm, law firm or in-house tax department
• degree in Tax or Accounting
• accurate, deadline-driven and collaborative
• result-oriented, disciplined and quality-driven

Nice-to-haves

• familiarity with AI-assisted tools (e.g., Claude, ChatGPT, Copilot) and platforms such as Alteryx or Power BI
• knowledge of Pillar 2 / GloBE
• prior involvement in digitalisation or process automation
