Job description

Build with us

Since 2004, we've had one clear goal: to make payments and money management effortless for every business in Europe.

Today, more than 250,000 companies use Mollie to get paid, manage money and grow, with products designed to be simple, scalable, and dependable.

With 950+ Mollies across 14+ locations, we care deeply about autonomy and craft. So we work in small teams, with real ownership, and we trust you to make the right decisions.

We're building for the long term, so we provide the tools you need, processes you can rely on, and a balanced work environment to help you do work you're proud of.

Sound like your kind of place? Let's build together.

Your impact

Treasury is where Mollie's balance sheet takes shape, this team makes sure that our balance sheet is safe, well-funded and resilient. You, as Treasury Manager, will be one of the first people building the Asset & Liability Management (ALM) function for Mollie.

This is a genuine 0-to-1 role. There is no legacy ALM framework to maintain, no existing ILAAP to update, no established models to inherit. You'll help design and build the liquidity risk framework, the interest rate and credit spread risk approach, and the funding and balance sheet strategy. Your work will feed directly into Mollie’s licence application and, once authorised, into how Mollie actually manages its liquidity and funding risks.

You'll work closely with our product teams, Finance, and Risk Domains and your analysis will be seen by senior leadership and, eventually, by our regulator. As Mollie moves from application to operation, your scope will grow from building the framework to running it.

What you'll ship

• Build and own the core building blocks of Mollie liquidity risk framework, including the ILAAP, LCR/NSFR monitoring, and liquidity stress testing.
• Develop Mollie’s approach to interest rate risk and credit spread risk in the banking book (IRRBB/CSRBB), from risk identification through to models, limits and hedging strategy.
• Contribute to the design of Mollie’s funding and balance sheet strategy, including deposit mix, funding diversification and balance sheet construction.
• Build the Contingency Funding Plan and related early-warning indicators, so Mollie knows exactly what to do under stress before it needs to.
• Produce clear, well-documented policies, methodologies and models that will stand up to scrutiny from DNB/ECB, external auditors, and Mollie's own second and third lines of defense.
• Support senior leadership (ALCO or its future equivalent) with the analysis, reporting and recommendations it needs to make sound balance sheet decisions.
• Partner with Risk, Finance and our external advisors, to make sure Treasury's frameworks are consistent with Mollie's wider risk appetite and governance.

What you'll bring

• Around 5+ years of experience in Treasury, ALM or balance sheet risk management, ideally within a bank, though experience in a fintech, PSP or consultancy building similar frameworks is also relevant.
• Solid working knowledge of liquidity risk (LCR/NSFR, ILAAP) and/or interest rate risk in the banking book (IRRBB/CSRBB). You don't need to be deep in both, but you understand how they connect to the balance sheet as a whole.
• Comfort building models and frameworks from a blank page. You're not looking for a well-worn playbook, you're excited to write the first one.
• Strong quantitative and Excel/financial modelling skills, with the discipline to document your logic clearly enough that someone else, including a regulator, can follow it.
• The ability to explain complex balance sheet risk topics clearly to non-specialists, and the confidence to defend your recommendations to senior stakeholders.
• Genuine curiosity about how AI can speed up the parts of this work that don't need a human, so more of your time goes toward judgment and design.

Grow your way

At Mollie, growth is personal. We believe everyone should have the chance to develop their skills, explore new challenges and shape their career on their own terms.

You'll get regular feedback and performance reviews to support your development, with fair and transparent salary reviews along the way. Many Mollies move into new roles or take on new projects to stretch themselves, and we actively hire from within to help you take the next step.

No matter if you're aiming for promotion, exploring a different career path or building new skills, you'll be supported with the tools, trust and opportunities to grow your way.

Unlock your full potential and join us to eliminate financial bureaucracy.

If you're excited by the idea of building a bank's Treasury function from scratch, for Mollie and for thousands of businesses across Europe, we'd love to hear from you.
