Senior Commercial Finance Business Partner

Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.

As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.

We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.

You will act as the strategic co-pilot to our R&D Directors, Heads of Manufacturing, and Procurement leaders.

You will build, review, and challenge multi-million-euro business cases, track program-level IRR and NPV, and ensure that our aggressive investments in R&D and manufacturing capacity yield robust long-term profitability. This role requires a rare blend of deep commercial acumen, world-class financial modeling skills, and a strong understanding of industrial unit economics (from R&D labs to factory floors and tier-1 supplier networks).
