Position Overview:

The Process Chemistry team, part of the CMC Synthetics organization within Sanofi R&D, is responsible for the design and preliminary process development of commercial manufacturing routes for drug substances undergoing clinical development. We strongly believe that innovation is an important driver to be successful and we focus a large part of our activity on developing new synthetic routes, concepts, and technologies to provide drug substances in the most efficient, robust, economical, environmentally benign, and intrinsically safe way. 

We are looking for a highly motivated and collaborative individual with expertise in synthetic organic chemistry, late-stage clinical development experience to join our Process Chemistry team at the Principal Scientist level. Under the direction of Process Chemistry R&D leadership, the primary responsibility of this role is to perform and oversee multi-step route evaluation and route development activities, with the aim of establishing commercial drug substance manufacturing processes through management and execution of internal and outsourced laboratory activities. This role may oversee the activities of one or more collaborators and be responsible for their professional development.

Key Responsibilities:

Design novel synthetic pathway for drug substances in clinical development.

Conduct and oversee route scouting in laboratory to demonstrate synthetic viability.

Use all imaginable chemistry tools and methods to establish and develop new synthetic pathways (photochemistry, biochemistry, flow chemistry, electrochemistry, on-line analysis, high throughput experimentation, structural analysis (NMR, UPLC/MS), etc.) into efficient, eco-designed and robust manufacturing processes for synthetic drug substances.

Analyze experimental data to drive synthetic experimental plans.

Assist in the design, planning and execution of multi-step experimental plans guided by risk assessment to deliver safe, efficient, robust and scalable drug substance manufacturing processes.

Investigate optimization and scale-up of reaction and purification unit operations.

Lead and collaborate within project teams by working closely with analytical chemists, process engineers, pilot plant experts and project managers within the CMC Synthetics organization.

Communicate scientific results in a clear, concise, and accurate manner via electronic laboratory notebook documentation, development report, project discussion and presentation.

Draft and review technical reports, external publications and patent applications.

May include management of outsourced laboratory activities: generating scope of work, supervising activities at CDMOs, validating reports for outsourced activities.

Basic Qualifications:

Ph.D. in organic chemistry with a minimum of 5 years of experience within a small molecule process development organization

Demonstrated expertise in modern synthetic organic chemistry with late-stage clinical and DS process validation (PPQ) experience.

Knowledge in at least one of the following areas: advanced analytics, flow chemistry, high throughput experimentation, lab automation.

Experience in chemocatalysis or biocatalysis including characterization of catalytic processes and/or mechanistic analysis.

Strong publication record in peer-reviewed journals.

Excellent written and verbal communication skills.

Experience in the management of internal scientists and/or subcontractors.

Ability to operate with flexibility in a dynamic environment and with tight deadlines.

Strategic and innovative thinker with a track record of fresh insightful thinking by developing creative approaches to processes and practices.

Preferred Qualifications:

Post-doctoral experience.

Proficiency with Microsoft suite

Familiarity with digital tools (e.g. Scifinder-n, Reaxys) and advanced data analysis software (e.g. Spotfire).

Design of experiment, statistical and/or thermo-kinetic modeling

Computational capabilities (e.g. molecular dynamics) and basic coding skills.

French language skills.
