Finance Manager (AI Native) | VC-Backed SaaS | London / Hybrid
The Client
Harmonic is exclusively partnering with a fast-growing, VC-backed enterprise software business that helps large organisations automate complex, high-stakes operational workflows using AI. Their products are used by major enterprises across sectors.
Around 40 people, ambitious growth targets, and a culture that is genuinely technical across every function. They don’t just talk about AI - they build it. And now they want to run their own finance and operations function the same way they sell their product: AI-native, systemised, and lean.
This hire is a major investment in building the finance function to be the engine room for the whole business, and there is real scope to shape what it becomes.
The Role
Reporting directly to the CFO, the Finance Manager will own the finance operations layer as the sole finance hire below CFO level. The mandate is to automate the close, modernise the systems stack, and progressively build a function capable of supporting a business scaling toward $15m ARR with minimal manual overhead. The CFO retains FP&A and strategic finance; the expectation is that this person grows into those areas as the function matures.
This is an individual contributor role with direct CFO access and broad reach across finance operations, revenue operations, and internal AI deployment alongside the engineering team. The role is suited to a qualified accountant who wants to move beyond the month-end cycle and into a mandate where agentic AI is the primary tool for creating leverage.
Responsibilities
- Own the month-end close end-to-end, with a clear mandate to automate: target five business days or fewer, with the majority of journals running automatically
Experience Requirements
Essential
- Qualified accountant (ACA / ACCA / CIMA or equivalent), with 2 to 4 years of post-qualified experience
- Experience owning month-end close and management accounts end-to-end in a scaling or start-up environment
- A hands-on, agentic approach to AI: you are already building and configuring AI workflows in a real work context, not just using AI tools day-to-day
- Comfortable working directly alongside engineering and data teams
- Start-up or scale-up background, with the ability to operate without a support function
Desirable
- Experience with modern or AI-native ERP platforms (Rillet, Campfire, Light, or similar)
- HubSpot or CRM-to-ERP integration experience
- Workflow automation experience (Zapier, Make, n8n, or similar)
- Familiarity with SaaS revenue recognition (IFRS 15 / ASC 606)
Salary: £65,000 – £75,000 + considerable share options
Location: West London, 3 days in office / 2 days remote
Start Date: Notice periods considered
