Head of Finance AI Transformation Logistics Tech Scale-up

Head of Finance Transformation (AI & Automation) Hypergrowth Logistics Tech Scale-up Farringdon

Harmonic have been retained by an exceptionally high-growth, VC-backed logistics-technology company on a mission to strip the hidden cost of delivery out of ecommerce, making it easier for more goods to move between more people. Backed by several tier-1 investors, this is one of the fastest-scaling venture-backed businesses in Europe, and finance is being built from scratch to keep pace.

The Opportunity

They're building a finance function that scales faster than the business, not by adding headcount, but by designing a system where AI, automation and clean architecture do the heavy lifting.

They're looking for someone to build that system from scratch: the finance stack, the AI workflows, and the operating model that ties it all together. Reporting to the CFO, you'll work directly with founders and functional leaders to turn finance into a real-time decision engine.

This is not a "transformation" role in the traditional sense. This is a 0 to 1 build role with direct leverage on company velocity.

What You'll Own

• Design the finance function from first principles: own how finance operates in an AI-native, high-growth company, not as an improvement on legacy systems, but as a definition of the default state. Rebuild core processes (record to report, procure to pay, order to cash, FP&A) to eliminate manual work before it takes root.
• Deploy AI across every high-leverage workflow: identify and ship use cases in weeks, not quarters. AI-driven forecasting and scenario modelling, automated reporting and commentary, close and reconciliation workflows, and collections, risk and anomaly detection.
• Build and own the technical stack: select the minimum viable, maximum scalable architecture. Make strong calls on ERP vs lightweight tooling, build vs buy, and data design. Ensure everything is modular, API-friendly and AI-ready from day one.
• Work directly with engineering and data teams: translate financial logic into production systems. This is a hands-on, cross-functional role; you're putting ideas into production, not handing them over.
• Redesign the operating model around augmentation: define how humans and AI work together, including which roles don't need to exist. Build a function where one great operator and AI outperforms five traditional hires.
• Deliver the outcomes leadership needs: reduce time to close, time to forecast and time to decision. Give leadership real-time, high-quality financial insight, and build systems that scale to £100m+ revenue without breaking.

Who Will Thrive In This Role

• You've built or redesigned finance systems and operating models end to end, not just advised on them.
• You've deployed automation or AI in real finance workflows. Production, not strategy decks.
• You think in systems, not processes, and you're comfortable making decisions with incomplete information.
• You've worked closely with CFOs, founders or operators on scaling finance in high-growth environments.
• Proven experience owning finance programmes and delivering systems implementations end to end.
• Strong technical fluency; comfortable working directly with engineering and data teams.
• A structured, clear communicator with strong stakeholder management skills.
