At BOI, finance sits close to the business. As Finance Manager you'll own the full finance function across our Belgian and US entities, from daily operations to management reporting, compliance, and system infrastructure. You report directly to the COO and work with our Belgian accountants and US CPA.

This is the right role if you've built your foundation in a Big 4 or finance outsourcing environment and want to stop advising and start owning. You'll be the internal finance lead in a fast-growing, international AI studio of around 50 people, with real scope, real decisions, and no-one above you in finance.

Who we are

BOI is an AI Transformation Studio, with offices in Antwerp and New York, that helps the world's leading businesses grow and transform with AI. For more than 16 years we've partnered with ambitious businesses like Nestlé, ING, Walmart, Coca-Cola, GSK, SD Worx, J&J, and Mastercard.

We’re a collective of engineers, practitioners and strategists, who’ve done this work inside global organizations. We’re radically independent, vendor-agnostic, outcome-obsessed, and focused on delivering impact in weeks, not years.

What you'll do

You'll own end-to-end finance across both our Belgian and US entities. You won't be handed a fully built system, you'll help shape it.

You will:

• Run monthly close and management accounts, cash flow monitoring, and short-term forecasting
• Track project profitability and produce ad hoc financial analysis for the COO and partners
• Own client invoicing, revenue recognition, AR follow-up, and intercompany billing between entities
• Manage AP processing, supplier payment runs, consultant expense reimbursements, and bank reconciliation
• Handle VAT filings, Belgian tax compliance, and US compliance coordination with our CPA
• Coordinate payroll with our Belgian social secretariat
• Manage our current finance stack (Exact Online, Xero, Spendesk, Google Sheets, Bright Analytics) and co-own our Odoo migration through end of year, taking over full operational management once it goes live

What we're looking for

3-5 years in finance, ideally in a Big 4 or finance outsourcing environment, you know the rigor, and now you want to own something. You're done advising and ready to run a full finance function in a fast-moving international scale-up. Experience in a professional services or project-based business is a plus — you'll need to understand how time and revenue connect. Exposure to US entity finance is an asset. You're comfortable owning a system migration from day one, not just landing in one after the decisions were made. Fluent in English and Dutch.

You'll thrive in this role if you…

• Want real ownership, not a narrowly scoped controller position
• Are comfortable with ambiguity and can structure problems without a playbook
• Get satisfaction from getting numbers exactly right, you trace the variance, you don't let "close enough" slide
• Care about the business behind the numbers: project margins, cash timing, entity performance
• Move fast, communicate clearly, and don't need much hand-holding
• Are genuinely interested in what AI can do for finance operations

Here's what you can expect when you join us

A high-performing international team across Antwerp and New York, working at the front of AI transformation. A finance role with full scope, you set the agenda, not just execute it. A fast-paced environment where your work feeds directly into business decisions at partner level. A culture that values directness, initiative, and high standards, with trust from day one.

BOI is an equal opportunity employer: we celebrate diversity and welcome all backgrounds and identities.

Sounds like your next challenge? We can't wait to meet you.
