About the opportunity
At QIAGEN Digital Insights (QDI), we develop industry-leading bioinformatics software and curated knowledge bases that help researchers, laboratories, and clinicians transform molecular data into actionable insights.
As a Senior Engineer, you will take ownership of building and evolving server-side systems and data-intensive services, primarily using Java. You will work on distributed systems, APIs, and processing pipelines that support complex clinical and research workflows. This is not a typical CRUD back-end role – the focus is on scalability, correctness, performance, and reliability in a regulated domain. Exposure to Java, object-oriented programming, and Python is a plus, since parts of our backend ecosystem use these technologies. You will also play a key role in technical decisions, mentoring, and raising back-end engineering standards within the team.
Your tasks
Design, develop, and enhance scalable backend services and distributed systems using Java and related technologies
Build and evolve APIs, processing pipelines, and platform services that support genomic and biomedical data workflows
Drive technical architecture decisions with a focus on scalability, reliability, performance, and maintainability
Collaborate closely with Product Management, Frontend Engineering, DevOps, and other cross-functional teams to deliver high-quality solutions
Implement automated testing practices and maintain high engineering standards through code reviews and engineering best practices
Mentor engineers and contribute to the continuous growth of engineering capabilities within the team
Support technical discovery activities, solution design discussions, effort estimations, and feasibility assessments
Your profile
5+ years of professional software development experience, with strong expertise developing production-grade applications using Java (Java 21+)
Solid understanding of object-oriented design principles, software architecture patterns, and engineering best practices
Experience designing, building, and operating distributed backend systems with a focus on scalability, reliability, and performance
Strong experience designing, developing, and consuming REST APIs
Experience with concurrency, asynchronous programming, data processing, and backend testing frameworks such as JUnit, Mockito, or similar
Hands-on experience working with relational databases (SQL)
Proficiency with Git-based development workflows, code reviews, and collaborative software engineering practices
Nice to have:
Working knowledge of Python for scripting, automation, or data processing, alongside experience with event-driven and streaming architectures
Exposure to healthcare, biotech, or other regulated software environments, with familiarity with CI/CD practices
