Chief of Staff

Why We Exist Belgian compensation plans are lagging behind: outdated products, minimal transparency, and overwhelming paperwork. Employees worry about their financial future. HR teams are buried in admin. The system is due for radical change.

Enter Warren. We are pioneering a new category: Wealth Enablement. We make pensions, benefits, and investing genuinely modern, clear, and valuable—for everyone involved.

We’re on an ambitious journey to reimagine how people build financial security in Belgium, and our momentum is real. The fundamentals of our business are being shaped now, and the decisions we make together will determine Warren’s legacy for years to come. Ready to help us build it?

What You’ll Own As our first-ever Chief of Staff, you’ll serve as the right hand to our founders. You’ll operate in the thick of strategy, finance, product, ops, and go-to-market.

But make no mistake—this isn’t a calendar management job. This is a high-impact, highly autonomous role for someone who loves uncertainty and is energized by complexity. You’ll tackle ambiguous challenges, drive clarity, and ensure decisions become reality. You will bridge ideas, people, and execution across the company.

If you want a front-row seat to how a category-defining company is built—but more than that, you want to play a pivotal role in actively shaping it—this is your moment.
