Finance Engineer

Twentyfour Industries is growing fast, and our finance function needs to scale with it. We're looking for a Finance Engineer to own our finance workflows, accounting automation, data flows and data visualisation. You'll report to our Head of Finance and help design the systems that let the business scale.

We're AI-first. We use Claude and Lovable heavily, and our finance stack runs on Light, so you'll be building with modern tooling from day one. Our dedicated AI Architecture team owns the ERP and platform layer and supports you on cross-functional topics. You own the finance outcome.

• Build and maintain data pipelines that bring multiple sources into a central data lake
• Improve reporting and visualisation: BI, dashboards, data models, KPI infrastructure and management reporting
• Own accounting automation across close, reconciliations, AP/AR and intercompany flows
• Support the infrastructure behind month-end close, so data flows correctly from source systems to reporting
• Keep our finance systems aligned with the AI Architecture team, which delivers the ERP and integration platform
• Build AI agents, validation logic and automation frameworks that remove repetitive manual work from close, reconciliations and reporting
• Give FP&A the technical layer it needs: model inputs, automated pulls of actuals, variance data and dashboard infrastructure
• Work with the AI Architecture team on ERP, APIs and workflow orchestration. They own the platform, you own the finance outcome and the data alignment

• Have 3–5 years of experience in finance systems, finance engineering, data analysis or business operations
• Have implemented, or heavily configured, finance systems of record
• Are comfortable writing scripts, working with APIs and building automation workflows
• Have worked in Microsoft / Azure environments
• Take ownership and want to shape, maintain and improve how our team and business operate
• Like working across teams and would rather build with others than build platform infrastructure alone
• Do well in a fast-scaling, sometimes ambiguous environment, and are eager to understand finance processes and turn them into systems
• Speak English fluently (C1) and German at B2 level or higher

• Hands-on experience with Light or a similar AI-native finance platform (e.g. Rillet, Campfire)
• Experience with BI tools
• Exposure to AI agent or automation frameworks for finance workflows
• Familiarity with multi-entity accounting and intercompany data flows

• A builder role at a fast-growing defense-tech company that contributes to Europe's security
• The freedom to design our finance systems with an AI-first stack from day one
• Close collaboration with our Head of Finance and our AI Architecture team
• Virtual shares, so you share in the company's success
• An egym Wellpass membership for sports and wellness
