Role Summary

Join Mistral as a Finance Tech Intern and play a key role in shaping our state-of-the-art Finance Tech stack alongside our Revenue Stack Expert. You’ll stabilize ongoing projects and streamline day-to-day operations, enabling our team to focus on long-term innovation.

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.

Enjoy high autonomy and ownership as you collaborate directly with the Finance team to build and deploy new processes.

What you will do

• 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.
