Senior Software Engineer

Overview

Certara accelerates the potential of bringing medicines to market and to patients using biosimulation software, technology, and services to transform traditional drug discovery and development. Our clients include more than 2,400 biopharmaceutical companies, academic institutions, and regulatory agencies across 70 countries.

Our goal is to enable the life sciences industry's use of data, modeling, and analytics to make better decisions across the various phases of discovery and drug development. Our software and scientists incorporate modern advances in scientific understanding, drug development experience, data analysis, and AI resulting in significant opportunities to decrease the cost and increase the probability of success for new drug approval and commercialization.

As a Senior Software Engineer on the Phoenix Cloud team, you'll work at the intersection of cloud technology, modern data workflows, and pharmacological science. Phoenix Desktop is the industry's gold standard for PK/PD analysis (pharmacokinetic/pharmacodynamics analysis) and modeling, the science behind determining safe and effective drug dosing that has helped bring thousands of medicines to patients worldwide. Trusted by the FDA, academic researchers, and leading biopharmaceutical companies for over 30 years. With Phoenix Cloud, we're reimagining the entire "data in" to "report out" workflow by bringing it to the cloud, making it faster, more powerful, and streamline for research teams worldwide.

The Phoenix Cloud platform is a growing suite of cloud-native modules that extend the analytic core of Phoenix with powerful capabilities, from publication-ready graphing (TFL Studio) to GenAI-powered report authoring (AI PK Reports), with more modules on the horizon. You'll be building software that directly accelerates the pace of drug development, helps scientists spend less time on mechanical data work and more time on the science that brings life-saving medicines to patients.
