Your Impact

As a Senior Software Engineer with the Life Sciences Data and Analytics CoE, you will develop full stack software applications in a Life Sciences context, leveraging GenAI-supported insights, tools, or accelerators when relevant. You will deliver highly performant, tested, and scalable code, and participate in architecture decisions with the team. You will own product deployment and production performance, potentially using GenAI-based observability or anomaly detection tools.

You will mentor and coach junior team members through code reviews and pair programming, and encourage thoughtful use of GenAI tools in development. You will identify technical impediments and resolve them through architecture design, technology choices, or prioritization, considering GenAIs role in these pathways. You will collaborate with the Product Owner to align the roadmap with the existing architecture, including GenAI-enabled processes.

You will act as a thought partner to the Product Owner in story creation and acceptance criteria, clearly communicating tradeoffs in a GenAI-aware environment. You will help co-create engineering practices, coding style guidelines, and testing approaches, embedding GenAI considerations such as code suggestions, test automation, or documentation generation where appropriate.
