who you are

• Academic Background
  Student or recent graduate from a top engineering or business school, with strong analytical and quantitative skills and a clear interest in finance and strategy.

• Soft Skills
  Proactive, organised and reliable team player, able to manage several topics at once, work closely with the CEO and take ownership of your work.

  Previous internship experience in fast-growing start-ups, consulting, audit, banking, M&A or corporate strategy is considered a strong asset.

What You’ll Be Doing

You will work hand-in-hand with the CEO on a mix of financial, strategic and operational topics. Expect a high level of exposure, responsibility and variety, from deep-dive analyses to preparing key meetings and following up on action plans.

• Financial Reporting

Join a Startup That’s Redefining Access to Water

At Kumulus Water, we’re solving a simple but urgent problem: how to bring clean drinking water where it’s needed most. Our innovative machines pull water from the air, providing a sustainable, off-grid solution—without the need for pipes or infrastructure.

From schools to hotels to businesses, our technology is already making an impact, cutting plastic waste and offering a reliable alternative in water-scarce regions. With a fast-growing team in Paris, Madrid, and Tunis, and partnerships across Europe, Africa, and the Middle East, we’re scaling quickly—and we need ambitious people to help us grow.

Why You’ll Love This Role

• High-Impact Mission
  Work on a project that directly improves access to safe drinking water while reducing plastic waste and CO₂ emissions.
• Direct Exposure to Leadership
  Collaborate closely with the CEO and leadership team and see how strategic and financial decisions are made in real time.
• Steep Learning Curve
  Gain hands‑on experience across finance, strategy, operations and go-to-market, building a strong generalist toolkit early in your career.
• International Environment
  Interact with teams and partners across France, Tunisia, Spain, Saudi Arabia and other markets, in a multicultural, fast‑moving context.
• Real Responsibility
  Own your topics from day one. Your analyses and recommendations will feed into board, investor and strategic discussions.
• Career Springboard
  An ideal stepping stone for future roles in consulting, VC, entrepreneurship or strategy/finance positions in high‑growth companies.
• Step 1: HR interview - 30-minute call to review background, motivation, availability and basic fit with the role and company.
• Step 2: Interview with the CEO - 45–60-minute interview with Iheb to discuss experience, way of working, and expectations on both sides.
• Step 3: Case Study - Take-home or live case on a finance/strategy topic (e.g. simple model + short note). Debrief with the CEO and one team member.
• Step 4: Culture-fit conversation - Informal discussion with 1–2 team members to validate culture fit, answer questions and close the loop before offer.
