What I liked

Supportive team, excellent training programs, clear SOPs and strong emphasis on data quality. Benefits and PTO are good and the work feels meaningful in preclinical drug development.

Areas for improvement

Workloads ramp up around major studies, and being fully on-site can be a long commute some days.

What I liked

Hybrid model works well, strong mentorship and modern tooling. Cross-disciplinary projects with genomics and data science are interesting and help me build new skills.

Jan 10, 2025

What I liked

Strong compliance focus and good internal training for auditors. I learned a lot about global regulatory expectations and running audits.

Areas for improvement

Lots of bureaucracy from middle management, pay wasn't competitive for the role, and company restructuring created uncertainty before I left.
