Finance Manager

A week in the life of our Finance Manager:

• Monday: You're reviewing last week's ARR movement. A new logo closed Friday - you update the weekly management report, recalculate pipeline coverage, and send the snapshot to the leadership team first thing.
• Tuesday: Deep in the revenue model. You're working backwards from our 2026 target: how many AEs do we need, what quota should they carry, what ACV assumptions hold at different close rates? You flag two scenarios to the FD before EOD.
• Wednesday: In the office on Oxford Street. Back‑to‑back with the RevOps team to align on HubSpot pipeline definitions - you're building the underlying data structure that makes our FP&A meaningful, not just pretty.
• Thursday: Monthly close is coming. You're reviewing the management accounts pack from our outsourced accountants, reconciling actuals to budget, and feeding updated actuals into the FP&A layer - flagging variances to the FD before the leadership review.
• Friday: Unit economics. You're stress‑testing LTV:CAC ratios across our customer cohorts and drafting a short brief for the FD ahead of next week's board prep.

This is finance at Fifth Dimension. You're not a passenger - you're building the function from the ground up.

What you'll do:

• 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.

Bonus points if you have:

• Experience in proptech, real estate, or adjacent financial services.
• Exposure to multi‑entity structures (UK parent, US / Singapore subsidiaries).
• Hands‑on experience with HubSpot or similar CRM from a RevOps/FP&A angle.
• Previous experience supporting a fundraise or investor reporting.

What we offer:

• £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.

• 14 weeks full pay for primary caregiver (followed by statutory pay).
• 6 weeks full pay for secondary caregiver.
