Job description

  • Senior Fullstack / Backend role in a MedTech, AI and Computer Vision environment
  • 100% hands-on role in a small senior engineering team
  • Scope: medical platform, Python/Django backend, React frontend, APIs, scale, security and data workflows
  • English professional level expected; French is useful

A high-impact MedTech / AI engineering opportunity Join a Paris-based deeptech startup building AI and robotics technology to transform dermatology. The product creates a complete 3D map of the skin, helping physicians detect skin cancers earlier and follow changes over time with more precision. The company is entering a commercial scale-up phase after several years of R&D, with strong demand from hospitals and clinics and a growing volume of medical data to process. The role As a Senior Fullstack / Backend Engineer, you will build and improve the core platform used by dermatologists. You will work on a critical system combining healthcare, data, performance and user-facing medical workflows.

  • Develop and maintain the main platform in Python / Django / React
  • Improve the clinical interface used by physicians
  • Build secure APIs and internal services
  • Support scale-up challenges linked to large volumes of scans and images
  • Improve backend architecture, monitoring, performance and robustness
  • Translate medical and product needs into reliable technical solutions

Requirements

We are looking for a strong senior engineer with solid foundations, humility and the ability to build reliable software in a demanding product environment. Minimum experience required: 5+ years of professional software engineering experience after graduation. Profiles below this level are unlikely to be aligned.

  • Engineering degree / Master's degree strongly recommended
  • Python required, with strong backend fundamentals
  • Django required, ideally on production-grade applications
  • React required, with ability to contribute to product interfaces
  • Startup or demanding product environment experience strongly valued
  • Bonus: scale/data-heavy systems, MedTech, critical product, DevSecOps, infra, AWS, Terraform, Celery/SQS/RabbitMQ, Three.js, security or GDPR/HIPAA/ISO27001-like environments

Strong fit

  • Solid engineer with real production experience
  • Strong Python / Django / React stack
  • Builder mindset, clear communication and no ego
  • Comfortable with uncertainty and complex technical problems
  • Interested in healthcare impact and high-precision systems

Not the right fit

  • Bootcamp profile without strong engineering foundations
  • Very framed ESN / consulting profile with little product ownership
  • Frontend-only profile
  • High ego or low collaboration posture

Benefits & conditions

  • Competitive salary for a senior engineering role in medtech: €60k-85k gross/year depending on seniority.

  • Opportunity to work on cutting-edge technology: AI, computer vision, 3D reconstruction, medical robotics.

  • Tangible medical impact: code contributes to earlier skin cancer detection and better patient outcomes.

  • Real product already moving toward commercial deployment, not only research or proof of concept.

  • Small, senior team with high autonomy and direct access to founders.

  • Freshly funded company with runway and ambitious international roadmap.
