Who we are

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.

The role

Helsing's finance systems are scaling fast, and this role exists to ensure they scale with rigour. As Principal SAP Finance & Data, you will own SAP S/4HANA end-to-end: understanding its configuration, identifying where technical debt lives, and resolving it. Your immediate focus will be a thorough audit of the current SAP landscape, the elimination of manual workarounds, and a material acceleration of the month-end close cycle. Over time, you will set the standard for how Finance Transformation uses data and automation across Helsing, managing the Finance Data Engineer and translating technical complexity into plain financial language for all stakeholders. This role carries a clear trajectory toward SAP Solution Architect and Process Owner.

The day-to-day

Own and execute the SAP S/4HANA improvement roadmap, including configuration, module ownership across FI, CO, TR and MM, release planning, and the elimination of accumulated technical debt
Configure, test, and approve SAP changes directly, ensuring hands-on accountability rather than vendor dependency for standard tasks, and partner with the Finance Data Engineer to design the data architecture connecting SAP to Abacum and Citi
Govern the Finance Data Lake including data modelling, lineage, access controls, and quality SLAs, and manage vendor relationships with SAP, Abacum, and Citi
Design self-healing finance pipelines with automated anomaly detection, root-cause classification, and auto-remediation, and apply process-mining tools such as Celonis to map SAP transaction flows and identify optimisation opportunities
Represent Finance Technology in external audits, and communicate technical constraints clearly to Finance Operations, Engineering, Treasury, HR, and Legal

You should apply if you

Have built and owned SAP S/4HANA in practice, with deep configuration knowledge of FI and CO and working familiarity with TR and MM, and can operate independently of a vendor team for standard tasks
Are fluent in SQL and data modelling, and comfortable writing and reviewing Python scripts for data transformation and pipeline validation
Understand financial reporting to a substantive level, including IFRS, multi-entity consolidation, and intercompany eliminations, and can engage credibly with finance stakeholders
Have integrated banking platforms via API, with familiarity with treasury data flows and formats such as MT940
Have delivered finance technology programmes in regulated or government-contract environments, such as defence, aerospace, or deep-tech, and communicate fluently in both business-level German and English

Note: We operate in an industry where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don’t meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.

Nice to Have

Familiarity with agent-first automation approaches and experience evaluating AI agent alternatives before designing manual process steps
Background contributing to external audit processes in a finance technology capacity
