Job summary

watchTowr is a fast-growing cybersecurity finance function seeking a Finance Manager to own the end-to-end accounting engine across SG, UK and US. You will drive monthly closes, intercompany transactions, and audit readiness in a hands-on, execution-first role.

You will implement AI/automation to reduce manual work, ensure tax compliance across multiple jurisdictions, and build robust accounting papers and controls for non-standard transactions.

Qualifications

• Big 4 trained, with ACA, ACCA, CPA or equivalent, at least 4-6 years' post-qualification experience, and at least 1 year in a senior or lead finance role.
• Experience in a B2B SaaS business with multi-entity, multi-currency operations and hands-on subscription revenue recognition (IFRS 15).
• Proven track record of building and owning finance processes from scratch, not just following them.
• Strong technical accounting (revenue recognition, leases, ESOP, intercompany, deferred and accrued revenue), including writing technical papers with a proposed treatment.
• Hands‑on use of AI to automate recurring finance work. Show us what you have automated and what it saved.
• Experience owning tax and compliance across multiple jurisdictions, and identifying what is needed without being directed to look.
• You verify your own output and bring solutions with problems. You do not wait to be told what to do.
• Xero experience and advanced Excel skills.
• Comfortable learning new systems quickly. You will pick up tools such as Tipalti and ScaleXP on the job, and you learn them independently.
• Comfortable operating in a global business environment, working across time zones.

Responsibilities

• Own the monthly close end-to-end across SG, UK and US entities (GL, AP, payroll, intercompany), delivering management accounts, balance sheet, P&L and cash flow to deadline with no corrections at review.
• Run AP, payroll and expenses through our systems (Xero, Tipalti, HiBob) with zero out-of-system payments, and own bank reconciliations across all entities.
• Apply AI and automation as the default way recurring finance work gets done. You identify what is manual, design the automated solution yourself, seek VP of Finance approval and take it live.
• Own tax and compliance across jurisdictions (SG GST, UK VAT, corporation tax and HMRC, US state tax), keeping the compliance calendar current and holding outsourced advisors to a high standard.
• Own the annual audit end-to-end: the audit timeline, audit-ready financial statements, fieldwork, and downstream stakeholders (auditors, ESOP valuers, corporate secretaries).
• Build and maintain process maps, internal controls and technical accounting papers for non-standard transactions, to an audit-ready standard.

Job description

Hello, let us introduce ourselves!

watchTowr is the Preemptive Exposure Management capability trusted by Fortune 500 companies and critical infrastructure providers.

By combining proactive threat intelligence, real attacker telemetry, and automated red teaming, watchTowr continuously identifies and validates real exposure - so security teams can outrun real-world threats.

When exploitation happens in hours, watchTowr delivers what no one else can: time to respond.

We are a global team of operators, researchers, and engineers who have spent years thinking like attackers - and we are now building the technology to stop them. Our work is recognised across the industry, with original vulnerability research from watchTowr Labs and innovations like Instinct and Attacker Eye shaping the future of cybersecurity.

Backed by $29M in funding, recognised by Gartner, and scaling fast across the globe, we are in a high-growth phase of our journey. We are a young, high-energy, and research-driven team, obsessed with building world-class technology - and we want exceptional people to join us.

But what's the role?

As our Finance Manager, you will own the accounting engine of a fast-growing global SaaS business: the monthly close, tax and statutory compliance across Singapore, the UK and the US, and the annual audit. You'll build and run the processes that keep finance accurate and audit-ready, and use AI and automation to remove manual recurring work so that it is done right the first time, and fast. This is a hands-on, execution-first role. You spot issues early and bring the solution with the problem. This role is based in Singapore or the UK.

Sounds great - what will I do?

• Own the monthly close end-to-end across our SG, UK and US entities (GL, AP, payroll, intercompany), delivering management accounts, balance sheet, P&L and cash flow to deadline with no corrections at review.
• Run AP, payroll and expenses through our systems (Xero, Tipalti, HiBob) with zero out-of-system payments, and own bank reconciliations across all entities.
• Apply AI and automation as the default way recurring finance work gets done. You identify what is manual, design the automated solution yourself, seek VP of Finance approval and take it live.
• Own tax and compliance across jurisdictions (SG GST, UK VAT, corporation tax and HMRC, US state tax), keeping the compliance calendar current and holding outsourced advisors to a high standard.
• Own the annual audit end-to-end: the audit timeline, audit-ready financial statements, fieldwork, and downstream stakeholders (auditors, ESOP valuers, corporate secretaries).
• Build and maintain process maps, internal controls and technical accounting papers for non-standard transactions, to an audit-ready standard.

Sounds perfect to me, what specifics are you looking for?
