Senior Full-stack Software Engineer

Location: Warsaw, Poland
Hybrid model of work: 3 days in office, 2 remote per week

Position: Senior Full-stack Software Engineer

Are you a senior software engineer who wants to see your code make a real difference in drug discovery? Join our growing team building custom software solutions that directly support early drug discovery research at AstraZeneca.

As a Senior Full-Stack Software Engineer, you'll be a technical cornerstone of our team, designing and implementing end-to-end applications, from data processing backends to intuitive user interfaces, that solve complex computational challenges in biomedical research. Working closely with scientists, fellow engineers, and our technical lead, you'll translate scientific requirements into elegant, scalable software solutions while mentoring junior team members and contributing to engineering best practices.

This isn't about building generic enterprise software, it's about creating specialized tools that empower researchers to unlock the mysteries of human biology and accelerate the discovery of life-changing medicines through data-driven insights and AI/ML-enabled workflows.
