Accountant

Most accounting roles are about keeping books. This one is about building the function that keeps them. At Thunderstrike Aviation, you’ll own the day-to-day accounting and help move our entire finance operation from externally managed to fully in-house – where accuracy, control and clean numbers aren’t nice-to-haves. They’re the foundation the business runs on.

Thunderstrike Aviation is a fast-growing UAV technology company based in Odense, Denmark. We design and manufacture advanced unmanned systems used for defense, border security, search and rescue, and environmental monitoring across Europe. We operate with a startup drive and a craft-first culture – turning bold ideas into field-ready capability, fast.

As we scale, accuracy, compliance and doing things properly are not trade-offs. They are the foundation everything is built on.

The Role

This is a high-ownership role that will become the primary owner of operational accounting within Thunderstrike EU – and a key player in the shift from externally managed finance to a finance function we run and control ourselves. You’ll keep the books right today and help define how finance works tomorrow.

You’ll work across functions and countries, close the books through quarter-end and year-end, and build the internal controls and processes that a scaling company needs. We move fast and we learn faster – this is an environment where challenging assumptions and raising concerns early are strengths, and where the best idea wins regardless of where it comes from.

What You’ll Do

• Take ownership of the general ledger, including quarter-end and year-end close.
• Payroll administration.
• Run day-to-day operational accounting: accounts payable, employee reimbursements, expenses and fixed asset administration.
• Handle intercompany accounting across our EU and international entities.
• Own VAT, compliance and regulatory reporting to Danish requirements, including Intrastat.
• Strengthen internal controls and improve finance processes – bringing in automation and smarter tooling where it earns its place.
• Help bring finance processes in-house from external management – and build the internally controlled function that replaces them.

What We’re Looking For

You likely have a background in one or more of the following:

• Financial accounting and general ledger ownership
• Danish bookkeeping and VAT
• Quarter-end and year-end closing
• Intercompany accounting in an international group
• Finance process improvement or ERP implementation

Professional experience in several of the following:

• A degree in accounting, finance, business administration or a related field – or equivalent hands-on experience
• At least 3 years in a financial accounting role
• Strong knowledge of Danish bookkeeping and VAT requirements
• ERP systems and finance process improvements (SAP an advantage)
• Intrastat and VAT reporting
• Advanced Excel
• Fluent English, written and spoken (Danish is an advantage)

What matters most:

You take ownership of problems end to end – and you’re comfortable building where processes are still developing

High accuracy and attention to detail, with a structured, organised approach

You’re genuinely curious about where finance is heading – automation, AI, better processes

You communicate and collaborate clearly across functions and countries

You work independently and manage several priorities at once

You don’t need every line on this list. If you’re solid on the fundamentals and the idea of building a finance function, not just running one, is what draws you – we’d rather hear from you than not.

Why Thunderstrike Aviation

Finance you build, not just run

You’ll help build an internally controlled finance function rather than keeping someone else’s running. This is not a maintenance role.

Ownership from day one

You become the primary owner of operational accounting, working directly with the person you report to and across functions and countries. Real influence over how finance is done at Thunderstrike.

A growth-minded, craft-first culture

We’re curious about technology, we give honest feedback, and “not yet” beats “can’t”. People here take pride in doing things properly – and are expected to grow into the work.

International Environment

A genuinely international, multinational team – diverse perspectives on everything we build, with intercompany work across our EU and international entities from our base in Odense – the Nordic robotics hub.

Scale-up momentum

We are growing fast – from around 30 people toward 50+ before the new year, and beyond. Join early and help shape what we become.

How to Apply

Location: Odense. On-site, with room for occasional flexibility – no fixed work-from-home days. Reports to Anja H. B. Frandsen, Head of Accounting and Finance.

Applications are reviewed on an ongoing basis, so we encourage you to apply as soon as possible.
