Senior Software Engineer (Product & Platform Owner)

Location: Lyon France (Hybrid: 3 days onsite Monday to Wednesday)

Sector: Global pharma

Engagement: Long-term contract/freelance

The Opportunity

Join a world-leading healthcare pioneer dedicated to transforming the lives of millions through scientific discovery and manufacturing excellence. Within our specialized Digital Accelerator we bridge the gap between life-changing medicine and cutting-edge engineering. We dont just build software; we build the digital backbone that ensures vital treatments reach patients in over 150 countries. By joining this mission you will leverage the immense resources and stability of a global pharmaceutical powerhouse while operating with the speed autonomy and sophisticated tech stack of a high-growth startup.

We are looking for senior individual contributors who want more than just a ticket to code. We need engineers who want to be the primary engine of a products this role you arent just building features; you are owning a systems entire lifecycle from the first architectural sketch to production reliability and long-term maintenance.

Why This Role is Different

• High Autonomy High Impact: You will work in a small elite "Pod" (610 people) alongside Data Scientists UX Designers and Product Owners.
  

• True End-to-End Ownership: You own the "Build-Deploy-Run-Maintain" cycle. You have the keys to the infrastructure the CI/CD pipelines and the production environment.
  

• Technical Excellence: We dont cut corners. We value Clean/Hexagonal Architecture Trunk-based development and a "quality-in" mindset.
  

The Profile: Who You Are

• A Systems Thinker: You are a senior engineer who views software as a living entity. You take pride in building systems that are not only functional but observable reliable and easy to maintain.
  

• You enjoy solving problems across the entire stack. Whether its a frontend bug a backend API bottleneck or an AWS configuration issue you see it through to completion.
  

• Strategic Judgment: You thrive in regulated environments where your engineering decisions have real-world consequences. You are comfortable with ambiguity and have the judgment to build for the long term.
  

• The Technical Mentor: You lead by example pushing back on "heroics" or technical debt in favor of sustainable high-performing code.
  

• Fluent in English and French
  

Your Technical Toolkit

• The Modern Stack: Deep competence in React and TypeScript on the frontend paired with robust backend experience in Microservices and API design.
  

• Cloud Native Mastery: Extensive production-hardened experience with AWS. You dont just use the cloud; you understand it.
  

• Infrastructure as Code: You believe in a programmable world and use Terraform to manage infrastructure with precision.
  

• Architecture & Reliability: You have implemented Clean or Hexagonal Architecture in real systems. You prioritize observability (logging monitoring alerting) as a core part of your workflow.
  

• Delivery Excellence: You are a champion of Trunk-based development and own your CI/CD pipelines (GitHub Actions or equivalent).
  

How We Work

• Collaboration-First: We use Gherkin/BDD to define behavior before we build. We value clear English communication and the ability to explain technical trade-offs to non-engineers.
  

• Elite Performance: We follow DORA metrics (Deployment Frequency Lead Time etc.) to ensure our velocity is matched by our stability.
  

• AI-Empowered: We embrace AI-assisted development tools (like Cursor) to augment our productivity while remaining fully accountable for every line of code we ship.
  

• Pragmatically Agile: We value TDD and XP practices but we are pragmatic about when and why to apply them to keep the system healthy.
