Job Description

Finance Manager ================

We're looking for a Finance Manager to build 5D's FP&A function from scratch , the financial infrastructure that guides every major commercial decision between now and Series B.

About the role ——————-

As our Finance Manager, you'll own our weekly management reporting: ARR, pipeline coverage, forecasts , built interactively and delivered to the leadership team. You'll also build and maintain monthly management reporting: GRR, NRR, CAC, LTV:CAC, burn multiple, gross margin vs. assumption , with full P&L line items across sales & marketing, R&D, and G&A.

You'll build our revenue model: working back from annual targets to AE headcount requirements, quota levels, ACV attainment, marketing channel investment, and stage-weighted pipeline. You'll maintain cap table, options register, and company secretarial tasks , working with our outsourced providers but owning the internal layer.

Your responsibilities ———————

  • Own our weekly management reporting: ARR, pipeline coverage, forecasts , built interactively and delivered to the leadership team
  • Build and maintain monthly management reporting: GRR, NRR, CAC, LTV:CAC, burn multiple, gross margin vs. assumption , with full P&L line items across sales & marketing, R&D, and G&A
  • Build our revenue model: working back from annual targets to AE headcount requirements, quota levels, ACV attainment, marketing channel investment, and stage-weighted pipeline
  • Maintain cap table, options register, and company secretarial tasks , working with our outsourced providers but owning the internal layer
  • Act as the financial interface to RevOps , partnering closely on HubSpot data integrity, pipeline definitions, and revenue operations to ensure FP&A is built on solid ground
  • Support fundraising and board prep when needed , building the narrative and the numbers

What we're looking for ———————–

You've done FP&A in a VC-backed, high-growth B2B SaaS business , or you've been close enough to it that you know exactly what good looks like and how to get there. You're a generalist who can context-switch between controllership and commercial analysis without missing a beat. You make confident decisions when data is incomplete, and you're always asking 'what's the MVP to get us to Series B?'

You bring:

  • Qualified accountant (ACA, ACCA, CIMA or equivalent)
  • 3–6 years' post-qualification experience, ideally including time in a high-growth B2B SaaS environment
  • Strong FP&A foundations: revenue modelling, unit economics, scenario planning, management reporting
  • Genuine AI literacy , you use Claude or equivalent tools heavily in your workflow; building a model without them would feel like leaving performance on the table
  • Generalist mindset: equally comfortable running a cap table audit, building a quota model, and presenting to the CEO in the same week
  • Comfort operating with incomplete data and an instinct for pragmatic, high-quality outputs over perfect ones
  • A growth mindset , you want to be Head of Finance or Head of FP&A in a few years, and you're going to push yourself to get there

What we offer —————–

We're building something extraordinary , and we want extraordinary people. Our benefits package goes beyond the standard startup offering, from tailored support for life's challenges to meaningful parental leave.

  • £80–110k salary per annum + bonus + meaningful equity (on a standard vesting schedule)
  • Enhanced pension contributions (5%)
  • Unlimited annual leave
  • £100 monthly wellbeing budget
  • £1,000 annual training budget
  • Electric car scheme (salary sacrifice)
  • Tailored support for exceptional challenges, which may include contributions to:
  • Gender-affirming care
  • Private specialists and diagnostic scans
  • ADHD / Autism diagnosis
  • IVF / fertility care
  • Therapy
  • Enhanced parental leave
  • 14 weeks full pay for primary caregiver (followed by statutory pay)
  • 6 weeks full pay for secondary caregiver

Salary Min: 80000 Salary Max: 110000 Salary Currency: GBP Salary Period: year Required Skills: qualified accountant, FP&A, revenue modelling, unit economics, scenario planning, management reporting, AI literacy, generalist mindset, comfort operating with incomplete data Preferred Skills: genuine AI literacy, generalist mindset, comfort operating with incomplete data
