Head of Finance

About Aphex

We're the construction planning platform replacing outdated spreadsheets with multiplayer tools that delivery teams love. Major contractors like Laing O'Rourke, Acciona, CPB Contractors, and McConnell Dowell use Aphex to deliver projects from £50 million to multi-billion pound mega projects.

We're market-leading in Australia and the UK, with early traction in North America. Our teams support the people building the roads, rail, tunnels, and hospitals that millions rely on every day.

We're building the global orchestration platform for major project delivery—multiple products, multiple geographies, and the team to make it happen.

The Role

We're hiring a Head of Finance to build the finance function for the next phase.

We've scaled with a tiny finance team and a lot of resourcefulness. That got us here. It won't get us to where we're going. We need someone to professionalise finance without over-engineering it—build the infrastructure for scale while keeping us fast.

You'll inherit a working system, not a blank slate. External accountants in UK and AUS. Rippling for payroll. Xero, Chargebee, Airwallex. A family office FD who's done a brilliant job and will stay on as oversight. Your job is to take ownership of day-to-day finance, raise the bar, and build a small team that punches above its weight.

What You'll Do

Lead FP&A

Own and maintain the financial model, supporting forecasting, scenario planning, and cash runway analysis. Work closely with leadership to provide timely, decision-useful insights.

Run the machine

Month-end close across two entities. Payroll in four countries. Multi-currency treasury. Intercompany accounting. Revenue recognition on a subscription model. Billing and collections. Commission calculations. Your goal is to progressively systematise and improve these processes to ensure reliability and scalability. You’ll own and improve the core finance operations, working closely with external partners where needed.

Build the team

You'll hire and lead a small finance team—probably 1-2 people focused on finance operations. We're automation-first: every process you build should assume you won't have headcount to throw at it.

Be in the room

Partner with the leadership team, contributing financial insight to support decision-making and highlighting key risks

Why This Matters

We're building a global platform. New markets opening. Multiple products in flight. The decisions we make in the next few years will determine whether we become the category leader or an also-ran.

Finance isn't a support function here—it's how we know if our bets are working. We need someone who can give us that visibility without slowing us down. Someone who builds for the long term but moves fast in the short term.

We're not hiring a caretaker; we're hiring someone to build a scalable finance function as we grow the company.

About You

You've done this before (or you're ready to)

You've been a Finance Manager or Head of Finance at a scaling company—or you've been the senior finance person doing HOF-level work without the title. Either way, you know what good looks like and you're not intimidated by building it.

You're commercial, not just technical

You can close the books, but that's table stakes. What matters is whether you can translate the numbers into decisions. Can you sit in a leadership meeting and add value beyond the finance update? Can you challenge a plan that doesn't make sense?

You want to build a small, efficient team

You don't want a big team to manage. You want a small team that ships. You think about automation first, headcount second. You set high standards and hold people to them.
