This is a unique opportunity to contribute to Mistral's financial transformation from the ground up, experimenting with cutting-edge AI and data tools in a fast-paced, high-impact environment. Your work will include standardizing invoice-to-payment processes, creating onboarding resources for new joiners, and designing monitoring tools for billing and ERP integrations.

As a Finance Tech Intern, you will:

• Help scale the Procure-to-Pay operating model post go-live (hypercare support, issue triage, documentation, and adoption).
• Map and improve Finance workflows across tools such as Payflows (AP), SAP (ERP), Lago (billing), Kyriba (treasury), Anrok (tax), Navan (expenses), and Lucca (HRIS).
• Build clear documentation and runbooks for Finance users (how-tos, decision trees, "common issues" playbooks).
• Maintain a structured backlog of improvements, bugs, and requests, with crisp problem statements, impact, and next steps.
• Support governance topics such as cost center and approver matrices (alignment, validation checks, rollouts).
• Contribute to monitoring and controls: data reconciliation checks, dashboards, and lightweight KPIs to spot issues early.
• Help organize stakeholder routines: meeting preparation, follow-ups, and action tracking

Who you are:

We are looking for a candidate from a Tier 1 Engineering School (or dual degree/Business School with technical skills like coding or Python) who thrives in dynamic and cross-functional environments.

You should be analytical, structured, and comfortable navigating ambiguity, with a knack for identifying root causes and proposing pragmatic solutions.

Experience in scale-ups or operational roles is essential, along with a strong curiosity for how systems (AP, ERP, billing, treasury) interconnect and drive operational impact.

Familiarity with ERP/finance tools (SAP, NetSuite), data manipulation (spreadsheets, SQL, BI tools), or process mapping (BPMN, flowcharts) is a plus.

Above all, we value proactive problem-solvers who are eager to collaborate across teams and stakeholders to build efficient, scalable processes.

What we offer:

• Competitive cash salary and equity
• Daily lunch vouchers: Swile meal vouchers with 10,83€ per worked day, incl 60% offered by company
• Sport: Enjoy discounted access to gyms and fitness studios through our Wellpass partnership
• Transportation: Monthly contribution to a mobility pass via Betterway
• Health: Full health insurance for you and your family
• Parental: Generous parental leave policy
• Visa sponsorship
• Coaching: we offer BetterUp coaching on a voluntary basis
