Description du poste

ThinkSync is a deep-tech project within the Inria Startup Studio programme, working at the intersection of AI, philosophy, and mental well-being. The goal is to build a powerful AI-driven companion that supports reflective thinking and personal growth using an interdisciplinary framework of philosophy, psychology, and sociology.

You will join a focused team, working directly with the founder — an engineer and PhD graduate in video understanding and affective computing at Inria. ThinkSync has a functioning prototype, and is entering a critical year of fast iteration, technical refinement, and product–market fit validation.

Opportunities and Future Scope

ThinkSync is currently funded under the Inria Startup Studio programme, with a dedicated budget and research backing. If the product shows traction by the end of the 1-year CDD, we plan to register as a company. This role is a unique opportunity to shape the foundations of that company. If collaboration goes well, you may be invited to continue as CTO and co-founder.

Mission :

Your primary mission will be to develop, iterate, and test core product features for different user segments using fast prototyping methods and user feedback. You will work hands-on from Day 1, contributing both technically and creatively to an app that combines custom AI with deep philosophical insight.

Main Responsibilities

• Develop, test, and iterate front-end and back-end codebases (web / app stack flexible based on your preferences)
• Integrate AI models (LLMs and affective-computing modules) into the product
• Adapt and refine user flows and interfaces based on real-time feedback
• Contribute to the architecture and roadmap of a custom LLM aligned with human values and beliefs
• Analyze user behavior and prototype performance to inform product decisions
• Collaborate with researchers, philosophy counsellors, and advisors as needed
• Participate in all aspects of building an early-stage product (product, tech, user testing)

Required Skills & Experience

• Strong ability to build web or mobile apps with any modern tech stack
• Familiarity with tools like Cursor (or similar fast dev environments)
• Ability to work independently and manage time effectively in a fast-paced environment
• No specific degree or years of experience required — proven ability through personal, academic, or professional projects is key

Preferred (Not Mandatory)

• Familiarity with PyTorch and / or LLM fine-tuning
• Experience with industrial projects involving LLMs
• Network in relevant domains (AI, wellness, philosophy) that can benefit the project

Avantages

• Partial reimbursement of public transport costs
• Leave : 7 weeks of annual leave + 10 extra days off due to RTT (statutory reduction in working hours) + possibility of exceptional leave (sick children, moving home, etc.)
• Possibility of teleworking and flexible organization of working hours
• Professional equipment available (videoconferencing, loan of computer equipment, etc.)
• Social, cultural and sports events and activities
• Access to vocational training
• Contribution to mutual insurance (subject to conditions)

From 2692 € gross monthly (according to degree and experience).
