Finance Manager

We are looking for a hands-on and experienced Finance Manager to join our growing team and take ownership of the full accounting and financial control function at Optics11.

Optics11 is a world leader in fiber optic sensing technology for ultra-sensitive early warning systems. From our base in the Netherlands – a global hub for high-tech innovation and maritime expertise – we are on a mission to make the world safer by protecting critical infrastructure such as sea-lanes, offshore energy assets and subsea cables from disruption. Optics11 recently closed a €17m investment round.

As Finance Manager, you will play a central role in ensuring the integrity and reliability of our financial reporting and internal control environment. You’ll be responsible for the day-to-day accounting operations, monthly close and reporting cycle and cash flow forecasting. This role is ideal for someone with a solid background in audit or financial control who has since gained business experience in a dynamic, changing environment such as a scale-up.

You’ll report directly to the CFO and collaborate closely with stakeholders across the company (e.g. Sales, People, Operations and R&D) and a Junior Controller. This is a great opportunity for a proactive and hands-on finance professional who enjoys building processes, driving improvements and being involved in all aspects of finance.

• Maintain and improve internal control processes to ensure compliance with accounting standards and regulatory requirements.

• Coordinate statutory filings, audits and liaise with external accountants and advisors.

• Support the further development of project/WIP accounting and production-related financial processes.

• Monitor and manage capital expenditure planning and reporting in line with company budgets and investment priorities.

• Ensure alignment with the People team and manage coordination with the external payroll provider.

Cash Flow & Forecasting:

• Prepare and monitor cash flow forecasts to support financial planning and liquidity management.

• Monitor working capital development and support process improvements to optimize cash conversion.

Financial Process Improvement:

• Identify and implement improvements in finance processes and tools (e.g. full ERP in the future) to enhance efficiency, accuracy and scalability.

• Collaborate cross-functionally with teams in operations, commercial and product development to ensure alignment between financial processes and business needs.

• Support budgeting, forecasting and financial analysis activities as needed.

What’s in it for you?

• Competitive salary and benefits package.

• A key finance role in a high-tech scale-up with real impact.

• A dynamic international environment with short decision lines and plenty of room to grow.

• Hybrid working model for flexibility and work-life balance.

• A fun and collaborative team culture where innovation and initiative are valued.

What we’re looking for?

• Bachelor’s or Master’s degree in Accounting, Finance or related field.

• At least 5 years of relevant experience including several years in audit and experience in an in-house finance role.

• Experience in a fast-changing environment such as a start-up/scale-up is a strong plus.

• Solid understanding of Dutch GAAP (experience with RJ accounting standards is a plus).

• Strong skills in Excel and financial reporting tools; experience with Exact Online is an advantage.

• Hands-on, structured and proactive approach with strong attention to detail.

• Comfortable working independently while engaging constructively with a wide range of stakeholders.

• A working proficiency in Dutch is considered an advantage.

• Must already reside in the Netherlands.
