We work with clients to solve complex problems, optimise processes and support data-driven decision-making, collaborating with specialists and leaders across disciplines on long-term client relationships.

The role

Hybrid, based in Mexico City, with client visits within the city and occasional travel within Mexico.

The Commercial Scientific Associate sits at the point where scientific products meet the commercial and financial side of the business.

On the commercial side, key responsibilities include:

- Identifying and following up on opportunities with laboratories, hospitals, distributors and other healthcare or scientific organisations.
- Developing and maintaining relationships with existing and prospective clients.
- Preparing quotations, commercial proposals and supporting documentation.
- Presenting scientific and diagnostic products with enough technical depth to communicate credibly with laboratory professionals and other technical buyers.

- Maintaining an accurate and structured sales pipeline.
- Coordinating internally to ensure that client requests and commercial commitments are followed through.

- Coordinating information related to purchase orders, suppliers, imports and client payments.
