Job description

As a software engineer intern on Entropia's product engineering team, you'll play a hands‑on role in developing features across our solutions. You'll collaborate closely with GTM team members to design and implement secure, reliable systems that create real value for our customers. We're looking for curious, driven individuals eager to learn in a fast‑paced environment and contribute to reinventing data rooms while shaping the future of work.

This role is based in Paris, France. We mainly use an in‑person work model, with a flexible work‑from‑home policy.

• Contribute to product development by writing clean, maintainable, and well‑documented code under the guidance of senior engineers.
• Collaborate with cross‑functional teams (engineering, product, and GTM) to design, implement, and test features that improve our solutions.
• Participate in code reviews to learn best practices and ensure quality, security, and reliability.
• Support system security and scalability by helping build and test features that protect customer data and maintain high performance.
• Engage in agile practices (stand‑ups, sprint planning, retrospectives) and contribute to an iterative development process.
• Debug and troubleshoot issues alongside teammates to strengthen problem‑solving skills.
• Continuously learn and apply new technologies relevant to our stack, with mentorship and training from the team.
• A solid foundation in software development — Python FastAPI, PostgreSQL, Nuxt.
• A strong curiosity for AI, software architecture, and SaaS products.
• The ability to learn quickly, think outside the box, and contribute with energy to a close team.
• The desire to be part of an entrepreneurial journey at the very beginning of its story.

At Entropia, we are reimagining how organisations share, secure, and collaborate on their most critical information. Our virtual data room platform is built to handle the complexity of strategic transactions of all kinds, whether partnerships, financings, or major business milestones. We're creating the infrastructure that helps teams navigate high‑stakes decisions with clarity and confidence. Our broader mission is to augment collective intelligence: giving organisations the tools to transform sensitive data into structured insight, and enabling people to work together more effectively when the stakes are highest.

As a software engineer intern at Entropia, you'll be building systems where security, performance, and user experience meet. You'll solve challenging technical problems at scale, contribute to a product with real strategic impact, and collaborate with a team deeply motivated by the ways technology can shape the future of decision‑making. If you're ready to push the boundaries of applied technology and thrive in a fast‑moving, purpose‑driven environment, we'd love to work with you.

Compensation depends on the type of internship (final‑year or gap‑year internship).

Entropia is an equal opportunity employer, welcoming candidates of all backgrounds. If you're excited about our mission but feel like an alien, or are unsure if you meet every qualification, don't let imposter syndrome hold you back—reach out!
