Engineering Software Engineer

Want to boost your career at the intersection of AI, science and industry?

Biolevate builds AI-powered software that turns unstructured scientific data into reliable, collaborative workflows for medical writing and regulatory work. Our platform helps scientists, clinicians and medical writers move faster while maintaining the rigor their work demands.

Founded in Paris in 2024, we combine a commercial SaaS platform with in-house research in oncology and dermatology. It is an unusually practical place to work on AI: the systems we build are used both to advance scientific research and to help bring therapies to patients faster.

Why this role exists

Today, our product brings together several complex interfaces that support scientific work. We are now evolving it into a suite of focused applications and tools, such as an editor, a table and an assistant, which can be used independently or combined to address a broad range of user needs and use cases.

We are hiring a Software Engineer - Apps to help shape and build these applications end to end. You will create intuitive, agentic‑first experiences that help users work more effectively with scientific content and data, across the frontend, backend integrations and AI capabilities that power them.

What you’ll own

• Design, build and operate product features end to end,
• Build highly interactive product experiences, including AI‑assisted editors, data grids, collaborative workflows and scientific data‑exploration tools.
• Work closely with Product, Design, AI and Core engineers to turn user needs into well‑scoped, high‑quality releases.
• Make sound technical trade‑offs between speed of delivery, usability, reliability, performance and long‑term maintainability.
• Improve the shared foundations of our product: reusable components, APIs, testing practices, accessibility and observability.
• Contribute to technical direction and help raise the bar for engineering quality, product thinking and code ownership across the team.

What success looks like

After 3 months, you will have:

• Developed a strong understanding of our users, their scientific workflows and the product’s technical architecture.
• Shipped meaningful improvements to an existing product area with support from the team.
• Established productive working relationships across Product, Design, AI and Engineering.

After 6 months, you will have:

• Taken ownership of a substantial product area or workflow.
• Delivered end‑to‑end features that make a clear difference to users’ speed, clarity or confidence in their work.
• Improved part of our product foundations, such as performance, testing, component reuse, API design or reliability.

What will help you succeed

• Strong experience building and shipping web products with TypeScript and modern React‑based frameworks.
• Comfort working across the stack: building excellent user interfaces while integrating with APIs, backend services and data systems.
• Experience taking features from an ambiguous problem through design, implementation, release and iteration.
• A thoughtful approach to product quality: usability, performance, accessibility, reliability and maintainable code all matter to you.
• Ability to collaborate closely with non‑engineering partners and explain technical trade‑offs clearly.
• Curiosity and sound judgment when working with AI‑powered product experiences.
• Professional working proficiency in English.

You could be an especially great fit if…

• You have built complex, interactive applications such as editors, collaborative products, data grids, dashboards, design tools or scientific software.
• You have worked with real‑time collaboration patterns, such as CRDTs or operational transformation.
• You have worked with data‑intensive interfaces, virtualization or performance‑sensitive web applications.
• You have integrated product interfaces with AI or ML services.
• You have experience in a fast‑moving product team, a startup or a technical domain with demanding end users.

You might thrive in this role if…

• You enjoy solving user problems that are technically and scientifically complex.
• You are comfortable with ownership and ambiguity, and you know when to seek input rather than work in isolation.
• You care about the details of an experience without losing sight of the broader product outcome.
• You like collaborating across disciplines and learning from expert users.
• You want your work to have tangible impact in healthcare and scientific research.
