Senior Software Engineer; Web & Cloud

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.

A Senior Software Engineer at Certara, you will lead the design, development, and optimization of cloud-native, scalable web applications, APIs and services. Collaborating with developers, IT, Dev Ops, and science teams, you’ll drive technical solutions, mentor others, and ensure high-quality deliverables that support our business operations and customer needs in a dynamic, forward-thinking environment.

This is a greenfield opportunity to help build the future of the organisation. Our established desktop products have a long and respected history, but our future is in web, cloud and software-as-a-service, delivered to major pharmaceutical companies and regulators. You’ll help design and build that new platform from the ground up: high-profile work that sits right at the centre of the company’s direction.

AI-assisted engineering is core to how we work. We use tools such as Cursor and Claude every day to design, write and review code, and we expect everyone on the team to be fluent with them and to keep pushing how AI helps us build better software, faster. This is central to the role, not an optional extra.

We’re building the next generation of cloud-based workflow tools for our Simcyp products, the modelling and simulation software that pharmaceutical companies and regulators rely on to understand how drugs behave in the body long before they reach a patient. Today, modelling teams set up and run that work in many different ways, and results aren’t always easy to reproduce or share.

Our goal is to change that: to make sophisticated simulation workflows straightforward to build, share and run reliably at scale, with AI woven through the experience. This is greenfield work, and it’s the future of our business: high-profile, technically ambitious, and genuinely meaningful, because the faster and more reliably our customers can run their science, the sooner they can develop and deliver new medicines.
