Senior Manager, Finance Systems

About Us

Perk (formerly TravelPerk) is the intelligent platform for travel and spend management. Built to tackle the time‑consuming, manual work that gets in the way of real work, our tools automate everything from travel bookings to expenses, invoice processing, and more. By eliminating this shadow work that wastes hours, erodes morale, and saps innovation, we’re on a mission to power real work, with real impact. We’re trusted by more than 10,000 companies worldwide, including Wise, On Running, Breitling, and Fabletics, and we’re tackling the 7 hours of lost productivity per employee each week, a $1.7 trillion problem. Founded in 2015, Perk has grown into a global company of more than 1,800 people across 12 offices globally, with headquarters in London and Boston. We combine innovation, control, and simplicity to transform how businesses work and how people feel at work. At Perk, we’re driven by our values, like being an owner, delivering a 7‑star experience, and working as one team. We value curiosity, purpose, and mindset, not just knowledge, to unlock the power in your potential. Our talent team brings together leading minds from the travel and SaaS industries, representing over 70 countries. If you’re excited about having a real impact and shaping how millions of people experience work, we’d love you on the team.

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 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 Work

At 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. Please submit your resume in English if you choose to apply. Do not forget to submit an updated portfolio and/or resume.

We are an equal opportunity employer

Perk is a global company with a diverse customer base, and we want to make sure the people behind our product reflect that. 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.

Protect Yourself from Recruitment Scams

All official communication from Perk will always come from email addresses ending in @perk.com or @externalperk.com, our verified social media channels, or recruiters listed on our official LinkedIn page. We will never ask you to pay for equipment, training, or fees, request sensitive personal information such as bank details early in the process, or communicate through unofficial apps like WhatsApp, Telegram, or Signal. If you receive a message claiming to be from Perk that seems suspicious, please do not respond. Forward it to security at perk.com, and we will confirm whether it is legitimate.
