About Source Certain Limited

Source Certain Limited (SCL) is a fast-growing UK technology company providing provenance and traceability solutions across global supply chains. Operating through a main UK entity and two wholly-owned subsidiaries – one in the United States and one in Australia – SCL is at an exciting stage of its development, scaling its commercial operations while building the internal infrastructure to support sustained growth.

The UK entity is the commercial and operational hub of the group, with the majority of revenue, costs, and headcount sitting here. The subsidiaries are operational but smaller in scale, with activity that includes intercompany cross-charges. The business works across multiple time zones and with a broad range of external stakeholders including clients, auditors, banks, insurers, and legal advisers.

The Role

This is a broad and hands-on financial controller position, created to give SCL the day-to-day financial management and control it needs as it scales. The role sits at the heart of the business and will work closely with both the CEO and the Fractional CFO, providing accurate financial information, keeping the books in excellent order across all three group entities, and rolling up its sleeves on whatever operational matters need attention.

The right person will be comfortable being the primary finance resource in the business – organised, adaptable, and happy to move between a month-end close and sorting out an insurance renewal in the same morning. This is a genuine opportunity to shape how finance runs at SCL and to grow with the company.

• Monitoring filing deadlines across all three entities and ensuring the group remains compliant
