Description du poste

We’re a fast-growing biotech company on a mission to revolutionize cell biology and single cell analysis. Our platform transforms complex biological datasets into actionable insights through cutting-edge technology, empowering scientists and clinicians to make data-driven decisions faster and more effectively.

As part of our growing engineering team, you’ll work at the intersection of biology and software, helping to build world-class applications that bring our advanced scientific data to life through compelling and responsive user interfaces.

About the Role

We are looking for a Senior Front-end Software Engineer to lead the development of high-performance, user-centric web applications focused on interactive data visualization and complex charting components. You will play a critical role in shaping the user experience for scientists analyzing large-scale biological data sets.

This role requires deep experience with modern front-end technologies, particularly React, Redux, and data visualization libraries (e.g., D3.js, Highcharts, or similar), as well as a strong product mindset and a passion for building performant and scalable UI components.

What You'll Do

• Lead the architecture and implementation of new UI features in a large-scale React/Redux application.
• Design and optimize interactive charts, dashboards, and data visualizations that enable users to explore complex biological or clinical data.
• Collaborate closely with back-end engineers, and domain scientists to deliver intuitive and performant user interfaces.
• Continuously identify performance bottlenecks and lead efforts to improve rendering speed and responsiveness in the application.
• Contribute to UI/UX design discussions and decisions, especially related to usability in scientific contexts.
• Ensure code quality through code reviews, unit/integration testing, and adherence to best practices.
• Mentor junior front-end developers as the team grows and help guide technical direction on the front-end side.

Requirements

• Proven track record of building responsive, data-driven applications with complex interactive charts and visualizations.
• Solid understanding of HTML5 and CSS3.
• Experience with charting libraries such as D3.js, Highcharts, or similar.
• Deep knowledge of performance optimization techniques for web apps, especially around rendering large datasets.
• Experience working in Agile development environments and with CI/CD pipelines.
• Strong communication skills and ability to collaborate with cross-functional teams, including scientific domain experts.
• Ability to speak/read/write French (native or bilingual proficiency) & English (professional working proficiency).

Nice to Have

• Familiarity with WebGL, Canvas rendering, or GPU-accelerated visualization techniques.
• Exposure to back-end technologies, particularly around APIs that serve large datasets (e.g., GraphQL, REST).
• Experience working in biotech, life sciences, or other data-intensive scientific domains.
• Familiarity with ISO 13485 and Quality Management Systems for Medical Devices.

Why Join Us?

• Make a real-world impact on health and science.
• Join a collaborative, mission-driven team at the forefront of biotech innovation.
• Competitive compensation package.
• Work on technically challenging problems with a team that values innovation, mentorship, and personal growth.

We are an equal opportunities employer and welcome applications from all qualified candidates.
