Software Developer / Data Engineer

Location: Warsaw, Poland

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

Position: Software Developer / Data Engineer

Are you an engineer who enjoys working across both software development and data engineering? Join our team building custom software solutions and data infrastructure that directly support early drug discovery research at AstraZeneca.

As a Software Developer / Data Engineer, you'll contribute across application development and data pipeline engineering. Whether you're building APIs and user interfaces or developing data processing workflows, you'll work on production systems that scientists depend on daily. You'll take ownership of your work, troubleshoot issues independently, and collaborate with senior engineers and scientists to deliver impactful solutions.

This hybrid role offers the opportunity to deepen your expertise in your stronger area-whether that's software development or data engineering-while expanding your skills in the other. You'll work on both maintaining our existing scientific computing platform and building new capabilities, gaining broad exposure to modern technology stacks and data-driven workflows that power biomedical research.

What makes this role unique?

You'll be exposed to both software development and data engineering, giving you a broader skill set and more career flexibility. You'll work on projects that combine coding, data processing, and scientific problem-solving, all while being mentored by experienced engineers who are invested in your growth.
