About the Role:

Perk is a fast-scaling B2B travel booking and expense management platform operating across multiple geographies. Our Finance team runs on a growing stack of interconnected systems, and we need a hands-on, strategically-minded operator to own it.

As Senior Manager, Finance Systems, you will be the internal expert and accountable owner of our entire finance technology ecosystem — with NetSuite at its core. You will partner closely with Accounting, Strategic Finance, and Engineering to optimise how our systems operate, integrate, and scale. This is a high-impact, high-visibility role for someone who wants to be the person who makes finance run better.

What You’ll Do:

NetSuite — Core Ownership

Serve as the primary system administrator and functional lead for NetSuite ERP

Manage configuration, customisation (SuiteScript, SuiteFlow, SavedSearches), and release management

Own the NetSuite integration landscape, including connections to upstream and downstream systems

Drive the AR/AP, GL, and close-process optimisation agenda within NetSuite

Lead system remediation initiatives (e.g. unapplied cash cleanup, open document resolution)

Finance Systems Ecosystem

Manage and optimise the broader finance tech stack including evaluating new AI tools

Own the systems roadmap — evaluate new tooling, lead vendor negotiations, and retire legacy processes

Drive system integration projects end-to-end, partnering with Engineering where required

Controls, Compliance & Audit

Own IT general controls across finance systems as part of the SOX programme

Manage user access reviews, segregation of duties, and provisioning/deprovisioning workflows

Act as the primary liaison for auditor (Deloitte) and advisory (PwC) queries on systems and data

Maintain SOC report inventory and annual review process for all finance system vendors

Projects & Continuous Improvement

Lead systems implementation and upgrade projects from scoping through go-live

Identify and execute automation opportunities that reduce manual effort in the close cycle

Build and maintain systems documentation, including data dictionaries, process flows, and runbooks

Partner with Accounting and FP&A to translate business requirements into scalable system solutions

What We’re Looking For:

Essential

7+ years of finance systems experience, with at least 4 years as a NetSuite administrator or functional lead

Demonstrable hands-on NetSuite configuration experience: workflows, custom records, SuiteScript, saved searches, and reporting

Track record of owning cross-system integration projects from requirements through delivery

Solid understanding of core accounting processes (close cycle, AR/AP, consolidation) — enough to speak credibly with controllers and auditors

Experience supporting SOX IT general controls or equivalent audit-facing compliance work

Strong project management instincts: able to run multiple workstreams, communicate status clearly, and flag blockers early

Ability to operate independently in a fast-paced, ambiguous environment with limited hand-holding

Highly Valued

NetSuite certification (Administrator, ERP Consultant, or equivalent)

Experience with HiBob, Okta, LeaseQuery, or Carta in a finance context

Exposure to multi-entity, multi-currency environments

Familiarity with SaaS or B2B travel/expense tech — you’ll understand the business you’re supporting

Experience working alongside Big 4 auditors on systems and data queries

Who Will Thrive Here:

This role is not a ticket-taker. You will be expected to bring a point of view, push back when requirements are incomplete, and proactively surface problems before they become audit findings. The right person is equally comfortable in a configuration screen and a CFO meeting — and sees the connection between the two.

You are probably a good fit if:

You are genuinely energised by fixing broken processes, not just maintaining working ones

You communicate technical issues in plain language without being asked to

You have strong ownership instincts — if something is wrong in your systems, you find out before the auditors do

You are comfortable with ambiguity and can set your own priorities when direction is incomplete

You thrive in scale-up environments where the roadmap is built as you go

What We Offer:

Receive competitive compensation and equity ownership in Perk

Rest and recharge with 25 days of annual leave plus bank holidays

Take control of your physical health with private medical cover and voluntary dental insurance from Bupa, and discounted gym memberships with GymFlex

Plan for your future with our qualifying earnings company pension plan with Aviva

Know that your loved ones are protected financially through your Life Insurance if the worst were to happen

Rest assured that you’re covered by income protection in case you experience a long-term sickness or absence

Leverage tax-efficient cycle and electric car schemes with Cycle2Work & Octopus

Join our unforgettable Perk events, including our spectacular annual summer party

Always feel supported with Spring Health, our market-leading wellbeing partner, providing fast, comprehensive access to 12x therapy and 12x coaching sessions for you and your loved ones

Focus on your family with 12-16 weeks’ paid parental leave

Contribute to your community with 16 paid hours per year to spend volunteering for your dearest charitable causes

Broaden your horizons with up to 20 "Work from Anywhere" days per year

Stay savvy with access to a wide variety of discounts and rewards

Follow your passions and take a four-week, fully paid sabbatical once you reach 5 years

Let us help you move to one of our hubs with relocation support

AI at Perk

AI is embedded in how we work across every function. The tools you’ll use day-to-day are AI-enabled, so you can move faster and spend more time on the work that matters. In practice, that means using AI to research and prioritise work, synthesise information, and cut through shadow work — the invisible tasks that pull people away from the work only they can do — so you can focus on outcomes.

We don’t expect you to be an AI expert, but we do expect you to be curious and intentional about it. The bar is judgment: knowing when AI makes your work better, when to verify what it produces, and when to rely on your own expertise instead.

We’ll ask about how you use AI in your interviews — not to test tool knowledge, but to understand how you think about it. That reflects how we wo
