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
Rest and recharge with generous allocation of vacation days plus public holidays
Take control of your physical health with private healthcare or a gym allowance
Life Insurance protection for your loved ones
Perk events, including annual summer party
Wellbeing partner Spring Health with therapy and coaching sessions
Adaptable compensation plan
17 weeks paid parental leave during the child’s first year
16 paid hours per year to volunteer for charitable causes
Up to 20 Work from Anywhere days per year
Real‑life English, Spanish and Catalan lessons
Four‑week paid sabbatical after five years
Relocation support to one of our hubs
AI Fluency: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 work every day.
How We WorkAt Perk, we take an IRL‑first approach to work, where our team works together in‑person 3 days a week. As such, this role requires you to be based within commuting distance of our hubs. We fundamentally believe in the value of meeting in real life to improve connectivity, productivity, creativity and ultimately making us a great place to work.
For certain roles, we can help with relocation from anywhere in the world. English is the official language at the office.
We’re an equal opportunity employer, which means you’re welcome at Perk regardless of how you look, where you’re from, or anything else that makes you, well, you.
