At Cerrion, we’re building the future of AI-enabled manufacturing. Headquartered in Zurich and backed by Y Combinator and top Silicon Valley investors, we deploy video AI Agents that see what’s happening on production floors, spot problems automatically, and intervene in real time to keep production running smoothly, at global scale. Our technology is live in factories across 15+ countries, helping leading manufacturers in glass, beverage, food, CPG, building materials, and wood cut downtime by up to 50%. After successfully closing our Series A in November 2025, we're at an inflection point and scaling fast.
The Role
We're hiring a Working Student Finance to own core accounting and invoicing workflows – not to shadow, not to observe, but to run them. From day one, you'll manage vendor invoices, drive accounts receivable, and gain hands-on experience in month-end closing. You'll work directly with our Finance Lead across the full range of operational finance and actively shape how we build our financial infrastructure as we scale post-Series A.
What You’ll Do
Own invoicing end-to-end: Prepare, send, and track customer invoices. You’ll make sure every invoice is accurate, on time, and properly recorded.
Run accounts payable and receivable: Process incoming invoices, manage payment timelines, and follow up on outstanding receivables to keep cash flow healthy.
Manage employee expenses: Review and process expense reports, ensure compliance with our expense policy, and keep the reimbursement cycle fast and friction-free.
Own bookkeeping and financial records: Prepare journal entries, reconcile accounts, and maintain structured documentation of transactions and receipts – keeping our books clean, audit-ready, and built for scale.
Drive process improvements: Identify inefficiencies in our accounting workflows and propose better ways of doing things. At a scaling startup, nothing is set in stone – we want you to make it better.
Qualifications
Enrolled in a Bachelor’s or Master’s program in Business Administration, Finance, Accounting, or a closely related field at a Swiss university.
Hands-on accounting experience – whether from an internship, a previous working student role, or a part-time position. You’ve worked with real books, not just textbook examples.
Data-driven and detail-oriented: You don't just book numbers – you want to understand what they mean. You're comfortable spotting patterns, asking "why does this look off?", and you take pride in getting the numbers right.
Strong Excel / Google Sheets skills and AI-savvy – comfortable with formulas, pivot tables, and working with structured data. You actively use LLMs and AI tools to work smart and efficient.
Ownership mindset – You don't wait to be told what to do. When you see something that's broken or could be better, you flag it and fix it.
Fluent in German and English – German for day-to-day communication with local partners and authorities, English as our company language and for all financial documentation.
Available 40–70% with flexibility around your university schedule.
