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 Scala. 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 Scala, functional programming, or 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 Scala 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 8/11/17+)

• 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; exposure to GraphQL is an advantage

• Experience with concurrency, asynchronous programming, data processing, and backend testing frameworks such as JUnit, Mockito, or similar

• Hands-on experience working with relational and non-relational databases (SQL and NoSQL)

• Proficiency with Git-based development workflows, code reviews, and collaborative software engineering practices

Nice to have:

• Experience with functional programming, ideally using Scala, including familiarity with Scala ecosystem tools such as Akka, ZIO, Cats, or similar technologies

• 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 cloud platforms (AWS/GCP), containerised deployments, and CI/CD practices

What we offer

• Bonus/Commission

• Local benefits

• Referral Program

• Volunteer Day

• Internal Academy (QIALearn)

• Employee Assistance Program

• Hybrid work (conditional to your role)
