Tropic Square is a deep-tech company developing the world’s first transparent, auditable security chip. We are in a critical growth phase, transitioning from R&D to a venture-backed company. We don’t need a corporate CFO who manages spreadsheets from an ivory tower.
We need a hands-on Finance Manager who will own our numbers, guard our runway, and build the financial infrastructure we need to secure Series A funding.
We are open to both part-time and full-time collaboration, depending on mutual fit and availability.
If you’re excited to help build the financial backbone of a company entering its next growth phase, keep reading.
You'll be the right hand to the COO, ensuring our financial strategy is executed, not just planned
Own the Master Budget: Take full ownership of our financial model and budget planning and tracking
Cash Flow Management: Monitor our burn rate in real-time. Manage accounts payable (decide when to pay invoices to optimize cash flow) and oversee contractor payments
Runway & Reporting: Prepare the weekly "Survival Board" report for the Founders (Cash status, Runway in days, Burn rate)
Fundraising Support: Assist the CEO in preparing the financial data for Series A investors (financial projections, unit economics, historical data)
Process Implementation: Bring order, automation, and discipline to financial processes
HR & Payroll Admin: Oversee the financial side of the team—contractor invoicing, payroll preparation for the external accountant
Startup DNA: You have 3+ years of experience in a startup or scale-up environment. You understand terms like Burn Rate, Runway, Bridge Financing, Convertible Note, and ESOP
Data Wizard: You don’t just make tables; you build dynamic models. You can turn messy data into a clear dashboard and actionable insights
Direct & Transparent: You are not afraid to tell stakeholders: "We cannot afford this right now." You value brutal honesty over polite silence
Language Skills: English is your working language, and you’re fluent enough in Czech to handle local communication, including authorities and institutions
Detail-Oriented but Fast: You can spot a mistake in a 100-row spreadsheet, but you understand that in a startup, speed often beats perfection
Experience with Hardware/R&D companies (understanding Capex, inventory, manufacturing costs) is nice to have
Experience with Grant financing (EU/National subsidies) is advantageous
Opportunity to work alongside industry legends (Trezor founders) on a global deep-tech product
Flexibility: Full-time or part-time setup, friendly to parents and independent freelancers
Direct impact: Your work decides how long the company survives and when we raise investment
