This is a highly visible role combining strategic internal business partnering with direct support for important external commercial relationships.

Working closely with the Commercial Finance Director and senior leadership team, you will provide commercial insight, constructive challenge and decision support across trading performance, new business opportunities, pricing and strategic initiatives.

  • Analyse complex data to identify trends, risks, opportunities and the underlying drivers of performance.

  • Provide clear commercial insight across volumes, profitability, costs and wider trading performance.

  • Support commercial negotiations, new business opportunities and the evaluation of customer and partner propositions.

  • Drive improvements across pricing, value creation, reporting, forecasting and financial planning processes.

  • Support strategic projects, due diligence and ad hoc commercial analysis when required.

What we are looking for

  • A fully qualified accountant- ACA, ACCA or CIMA.

  • Significant experience within commercial finance, FP&A or senior finance business partnering.

  • Previous experience working within a large and complex organisation.

  • A genuinely strategic and commercial mindset, with the confidence to influence senior leaders and challenge constructively.

  • Strong budgeting, forecasting, pricing and financial modelling capability.

  • Excellent communication and relationship-building skills, with credibility at executive and C-suite level.

About The ONE Group

The ONE Group is a specialist recruitment consultancy with offices in Cambridge, Peterborough, Northampton, and Hertfordshire.

This focused approach allows us to provide deeper market knowledge, stronger networks, and better hiring outcomes for both clients and candidates.

Our expertise spans permanent, contract, and senior-level appointments. Most importantly, the majority of our business comes from repeat clients and referrals, reflecting the long-term relationships we build and the trust we earn through consistently delivering results.

What Happens Next

1

One of our consultants will review your application within one working day.

2

If your experience looks like a fit, we'll be in touch for a quick conversation to understand what you're looking for.

3

From there, we'll talk you through the role properly, prepare you for interview, and stay alongside you through to your start date.

4

Whatever happens with this role, we'll keep your details on file, with your permission, so we can flag other opportunities that suit you.

THE ONE GROUP

Where we're from,
and how we got here

Twenty years of specialist recruitment in the East – and a lot of small decisions that added up.

TOG started in Peterborough in 2004 with a small team and a simple idea: that recruitment is a people business, done best by specialists who stay in their sector long enough to know it properly.

More than two decades on, we've grown into four offices across the East of England and Home Counties. We recruit for finance leaders, HR directors, engineering managers, tech founders, scientists, and the commercial teams that keep businesses running day to day. Between us, we've built up over 258 years of collective recruitment experience across our specialist divisions, and a network of more than 150,000 candidates we've placed, coached, or come to know across two decades in the region.

The founding principle hasn't changed. Recruitment as it should be.

OUR STORY

Key events timeline

2004

Doors open in Peterborough.

Our first office launches with a team of six on Lynch Wood. Cambridge follows the same year, giving us two offices before our first anniversary.

2015

Northampton makes it three.

Our third office opens with a team of five, quickly growing to eleven consultants covering the wider Midlands region.

2017

Peterborough moves across the road.

The team has outgrown the founding office. We move into Arena House on Lynch Wood, big enough for a growing consultant base and the back-office team that supports the whole group.

2018

Cambridge moves too.

Our second office relocates to Cambourne Business Park, giving the growing Cambridge team the space it now needs.

2023

Four offices, three counties, one very good year.

The Hertfordshire & Essex office opens in Potters Bar, extending our footprint into the Home Counties.

In the same year, we're named Business of the Year in Northamptonshire, and Employer of the Year in both Cambridgeshire and Hertfordshire at the regional SME Business Awards. Three counties, three panels.

TODAY

Still growing.

Four offices, more than 258 years of collective recruitment experience across our specialist divisions, and a network of over 150,000 candidates.

Same founding principle.

SPECIALISTS BY DESIGN

What we do

We're specialists, not generalists. Every consultant at TOG focuses on one sector and stays in it. Not because it's the only way to do recruitment, but because it's how you build the depth to spot the difference between a strong CV and a strong hire.

It's also why so many of our clients come back to us years, even decades, after a first placement.

THE WAY WE WORK

How we work

Four principles show up in every conversation and every process.
01

Be curious.

We stay interested in the market we work in, and in the people who work in it.

02

Keep it human.

We remember your kids' names and know how you take your coffee. That's just how we work here.

03

Make a difference.

We're here to help people build careers they love and businesses they're proud of.

04

Enjoy the ride.

Recruitment is a career, but it should be fun too. If it isn't, we've done something wrong.

WHAT COMES NEXT?

Recruitment
as it should be.
