Are you an accounting leader who likes to own the full close—not just review it? Do you enjoy bringing structure to a finance environment that’s improving fast, but isn’t a “finished product” yet? If you’re hands-on, proactive, and comfortable being the financial reporting backbone in an international scale-up, this Head of Accounting role at AIMMS could be a great fit.
Why You’ll Love Working With Us
At AIMMS, we build optimization software that helps organizations make better decisions—fast. Behind the scenes, we’re strengthening and professionalizing our finance function to match our growth ambitions. This role is central to that journey. You’ll join a small, driven finance team where you’ll have real ownership, broad exposure (NL, US, Singapore), and the opportunity to materially improve how we run accounting, reporting, and compliance. You won’t step into a “monthly routine on rails.” You’ll step into a team that has already made major improvements—and is ready for the next step up in quality, consistency, and automation.
Your Role & Impact
In this role, you will:
-
Financial Reporting & Audit: Own the end-to-end monthly and annual close for four Dutch entities. You’ll be the primary lead for the annual statutory audit, managing the auditor relationship, preparing all documentation, and ensuring the final accounts are bulletproof.
-
Dutch Tax & Compliance: Act as the main point of contact for the Belastingdienst. You’ll own all filings (VAT, ICP, CIT, and payroll taxes) and maintain our transfer pricing documentation in line with existing agreements.
-
Payroll & Treasury: Partner with People & Culture to ensure flawless Dutch payroll runs and correct accounting treatment. You’ll also manage banking relationships, group liquidity, and weekly payment runs across the Dutch entities.
-
International Coordination: Provide group-level consolidation and align processes with our local partners in Singapore and our colleague in the US (Seattle), ensuring consistency in reporting across the globe.
-
Systems & ERP (Odoo): Take full ownership of Odoo from an accounting perspective. You’ll drive automation, optimize workflows, and ensure our system configuration supports a high-quality, efficient close.
-
Team & Stakeholders: Lead and mentor a Junior Finance Operations Specialist. Beyond the finance team, you’ll work cross-functionally with Sales, R&D, and People & Culture to translate business operations into accurate financial data.
What Will Help You Thrive and Be Successful
You’re someone who combines strong accounting fundamentals with real-world, in-house experience—and you’re not afraid to roll up your sleeves when needed. You bring structure, ask the right questions, and help the organization move from “good” to “great.”

AIMMS: Who We Are (and why it matters)
It all started in 1989, when we saw a huge untapped potential for mathematical optimization. Since then, AIMMS has touched many aspects of people’s daily lives—from the electricity delivered to our homes and the distribution of vaccines to emission-reduction policymaking. Today, as a product-led SaaS company, we support industries worldwide—from logistics to sustainability—enabling smarter, faster, and greener choices.
We’re a diverse, collaborative, and curious team of over 20 nationalities, with offices in the Netherlands (Haarlem HQ), the US, and Singapore. Working in a self-organized, hybrid way across the globe, we’re guided by four core values - Integrity, Care, Open, and Ambition - which help us give honest feedback, care deeply for our stakeholders, collaborate across teams, and continuously grow our impact.
How AIMMS made impact:
Remember the urgency of COVID? Our technology helped Dutch hospitals predict where ICU beds and staff would run short, and decide in minutes how to spread patients so no region was overwhelmed. That’s how we turn complex data into life-saving decisions – and the kind of impact you can have here.
