Job description

Overview

ReOrbit is redefining how satellites are built, launched, and operated. We design and deliver intelligent, software-defined satellites that bring unprecedented flexibility and performance to customers worldwide. Our growth is accelerating as we secure new customers, scale production, and deepen our technological edge in the fast-moving space industry.

We are seeking an experienced Senior Financial Controller to take full ownership of the company’s day-to-day finance, accounting, treasury, and compliance — freeing up our CFO to focus on strategy, investors, and growth. This is a high-impact role in a fast-growing deep-tech scale-up, offering strong exposure to leadership and potential for expanded responsibilities over time.

The Senior Financial Controller will be the end-to-end owner of ReOrbit’s finance function, supported by:
• One internal finance associate handling operational/transactional work.
• Our outsourced finance/accounting provider (e.g., GreenStep) for bookkeeping, payroll, and compliance execution.

You will be responsible for ensuring accuracy, compliance, and insight across all financial processes, preparing investor-ready reporting, and managing treasury and banking relationships.

It’s an exciting opportunity to join a dynamic start-up with the potential to make a real impact and support our goal of pushing the boundaries of space data transfer.

Responsibilities

• Financial Accounting & Reporting
• Oversee day-to-day finance operations including accounts payable/receivable, payroll, expense management, and general ledger.
• Manage month-end and year-end close processes in collaboration with outsourced accounting partner.
• Deliver accurate and timely management accounts each month.
• Prepare Board and investor reporting packs in a format ready for CFO presentation.

• Treasury & Cash Flow
• Manage banking relationships and oversee daily cash management.
• Execute and monitor payments, currency conversions, and term deposits.
• Maintain short- and long-term cash flow forecasts to support funding and growth planning.

• Compliance & Audit
• Own all finance-related compliance (tax, VAT, payroll, statutory filings) in collaboration with outsourced provider.
• Lead annual audit preparation and coordination with external auditors.
• Manage grant reporting and compliance for public funding.

• Budgeting, Forecasting & Analysis
• Lead the budgeting and forecasting process, working closely with the CFO and business leaders.
• Monitor budget vs. actuals and provide variance analysis with actionable insights.
• Support financial modelling for funding, pricing, and cost optimisation initiatives.

• Process & Controls
• Strengthen internal controls and ensure finance processes are scalable for growth.
• Drive process automation and efficiency improvements in finance operations.

Skills And Requirements

• 8–12 years of progressive finance experience, ideally combining accounting and FP&A in a start-up, scale-up, or high-growth SME.
• Solid understanding of Finnish accounting standards, tax, and compliance; IFRS experience is a plus.
• Proven experience managing outsourced accounting/finance providers.
• Hands-on treasury and cash flow management experience.
• Excellent Excel/Google Sheets skills; familiarity with modern finance tools (e.g., NetSuite, Xero, Power BI) a plus.
• Strong presentation skills and the ability to prepare investor/board-ready financial packs.
• Fluent in English; Finnish proficiency highly valued for dealing with banks and authorities.

Personal Attributes

• Ownership mindset — treats the finance function as their business.
• Detail-oriented, yet able to see the bigger picture.
• Comfortable in a fast-moving, scaling start-up environment.
• Hands-on when needed but also able to manage others effectively.
• Proactive communicator and collaborator with leadership and stakeholders.
