About the Role

Permutive is looking for a seasoned Controller or Senior Controller to own the accounting function across our US and UK entities. Reporting directly to the CFO, this person will be responsible for the integrity of our books, the timeliness of our close, and full compliance with statutory and regulatory obligations on both sides of the Atlantic. This is a hands-on role in a lean, high-expectations finance team — you will do the work, not just review it.

What you'll be doing?

• Own the monthly, quarterly, and annual close process end-to-end, including GL management, reconciliations, accruals, and intercompany eliminations across our US and UK entities

• Prepare and maintain US GAAP-compliant financial statements; manage the annual audit and the external auditor relationship

• Drive revenue recognition under ASC 606 across subscription and usage-based contracts, independently documenting positions and identifying edge cases

• Own US compliance end-to-end: federal and state income tax filings (with external advisors), multi-state SALT, payroll taxes, 401(k) administration and Form 5500, and 1099/1042 management

• Own UK compliance end-to-end: Companies House filings, CT600, PAYE and RTI submissions, P11D(b), workplace pension and auto-enrolment, VAT returns, and ERS reporting for equity awards

• Manage accounts payable, accounts receivable, multi-currency cash, and bank reconciliations

• Establish and enforce accounting policies and internal controls appropriate to a scaling SaaS business

• Own the ERP and accounting systems; identify and drive improvements to the close workflow and reporting infrastructure

• Partner with FP&A on chart of accounts structure and cost center design so reporting reflects how the business actually operates

What you'll need?

• Extenstive progressive accounting experience, the substantial majority in-house at technology companies; we are looking for someone who has operated as an owner, not an advisor

• Extensive experience with both traditional SaaS and transactional revenue models (usage-based, eCPM, marketplace, etc.) — ideally at companies with $50M+ in revenue

• Demonstrable, hands-on command of both US GAAP and UK statutory reporting — this is not a theoretical requirement; you should have filed CT600s and P11Ds yourself

• Ad tech (SSP, DSP, programmatic media, etc.) experience a strong plus; additional transactional model exposure (payment processing, revenue-share structures) is a meaningful differentiator

• Early-career public accounting experience is a plus; candidates whose background is primarily audit or advisory will not be the right fit

• CPA a plus but not required; ACA/ACCA qualification a meaningful differentiator given the UK scope of this role

• Experience of multi-entity, international groups

• Advanced Excel and ERP skills (NetSuite preferred); familiarity with Stripe, Maxio/Chargebee, or similar billing platforms a plus

• Technically precise with strong judgment on when to own a position internally versus when to escalate to external counsel

• To be as engaged by the business as you are by your close checklist

What we're offering?

We take a structured, objective approach to salary-setting, which is based on market information, our compensation strategy, and your experience and capability as assessed through our interview process. For a typical candidate who meets our requirements, we pay a base salary between $180,000 - $215,000 with a 20% bonus target on company and role performance.

Work Your Way

Permutive trusts you to manage your time and deliver results. Our hybrid model allows you to choose where you work best, whether in your own productive space or our London (Farringdon) or New York (Union Square) offices. That said, none of us work alone; we are part of a team. 

To foster collaboration and connection, teams in these locations come together in person at least once a week and are encouraged to benefit from being in our offices to meet with teams more often. Commercial and customer-facing teams are encouraged to embrace in-person interactions to build lasting relationships with clients and colleagues. 

Every Permutive employee gets together in person at the company’s Annual Kick Off for a week in February.  Each year’s event promises to be an exciting opportunity for us to come together, reconnect with colleagues, and align on our shared vision for the year ahead.
