Role Summary 

As our IFRS Lead, you will make Mistral AI IFRS-native by owning our transition from French GAAP to IFRS, shaping the financial backbone of one of Europe's fastest-growing AI scale-ups.

Reporting to the Accounting Director, you will build our consolidation framework from the ground up, develop scalable IFRS policies, and turn compliance into a strategic advantage for our global expansion. 

This is your chance to bridge startup agility with enterprise rigor, embedding financial excellence across our entities while collaborating with top-tier auditors and cross-functional teams. Your work will directly fuel Mistral AI's ambition, ensuring our financial processes match the pace and impact of our hypergrowth journey.

What you will do

IFRS Transition & Compliance:

• Lead the Group's IFRS transition in collaboration with external advisors.

• Monitor IFRS regulatory developments and applicable frameworks for external financial reporting.

• Analyze and document accounting treatments for complex transactions (position papers).

Policy & Tool Development:

• Develop and maintain the Group's IFRS policies (Accounting Manual).

• Implement financial reporting and analysis tools tailored to business needs.

Reporting & Stakeholder Collaboration:

• Support the reporting process (closing instructions, post-closing events, error tracking).

• Work closely with external auditors (Big Four or equivalent).

• Collaborate with statutory auditors for legal compliance.

• Assist in preparing periodic reports for the Board.

Technical Support & Training:

• Provide technical accounting support to teams, including operational tasks when needed.

• Prepare and deliver internal technical training sessions.

• Contribute to the implementation of consolidation processes.

Who you are:

• IFRS Expert (10–12 years of experience):

You have a proven track record in IFRS, including experience leading an IFRS transition project (ideally in tech, SaaS, or high-growth environments). You've worked with Big Four firms or equivalent, and you're comfortable interpreting complex standards and documenting position papers for auditors. Your expertise in French GAAP is a strong plus.

• Project Leader:

You thrive in fast-paced, ambiguous environments, turning regulatory complexity into clear, actionable plans. You've successfully managed cross-functional projects (e.g., ERP migrations, process harmonization) and can prioritize effectively under tight deadlines.

• Business Partner:

A strong communicator, you bridge the gap between technical accounting and operational teams. You simplify IFRS jargon for non-finance stakeholders and build trust by aligning goals across functions (Finance, Legal, IT).

• Tech-Savvy:

You're proficient with ERP systems (SAP S/4HANA is a plus) and understand how to leverage technology to improve financial reporting. You're hands-on and solution-driven.

• Proactive & Collaborative:

You take ownership of challenges, from high-level strategy to execution. Your mindset is adaptable and positive—you see obstacles as opportunities to innovate.
