Principal Engineer II, Fluidic Systems Integration, Research & Early Development

At Roche you can show up as yourself, embraced for the unique qualities you bring. Our culture encourages personal expression, open dialogue, and genuine connections, where you are valued, accepted and respected for who you are, allowing you to thrive both personally and professionally. This is how we aim to prevent, stop and cure diseases and ensure everyone has access to healthcare today and for generations to come. Join Roche, where every voice matters.

The Position

A healthier future. It's what drives us to innovate. To continuously advance science and ensure everyone has access to the healthcare they need today and for generations to come. Creating a world where we all have more time with the people we love. That's what makes us Roche.

At Roche, we are working to make next-generation sequencing simple and accessible enough for routine use. By accelerating clinical research, streamlining workflows, and expanding assay menus, we are broadening access to genomic data and lowering barriers to adoption. From robust sample isolation and preparation tools to novel sequencing technology and advanced bioinformatics, we are developing differentiated, highly integrated end-to-end solutions for next-generation sequencing, resulting in a sample in, result out workflow.

Our Systems Technology Group, a part of Roche Sequencing Solutions, is focused on creating and advancing technologies to significantly enhance DNA sequencing workflows. We are seeking a Principal System Integration Engineer II to serve as a critical bridge between fundamental scientific discovery and tangible engineering execution during the earliest stages of research and development.

This is a pivotal, hands-on role for a multidisciplinary expert who is passionate about pioneering new technologies by mastering the complex intersection of chemistry, molecular biology, and biochemistry with hardware, surfaces, and materials. The ideal candidate lives at the nexus of these domains, capable of translating the first principles of biology into novel fluidic and mechatronic systems. This role is designed to break the traditional R&D model where scientific and engineering teams operate in sequence. Instead of being a liaison between teams, this individual will be the embodiment of both disciplines, personally driving technology from a theoretical concept to a functional, proof-of-concept breadboard. You will be the inventive force responsible for answering the most fundamental question in our R&D cycle : "Is this new technology physically possible?" You will bring instruments from initial concept to demonstrated feasibility, laying the technical foundation for the next generation of sequencing platforms.

Role & Responsibilities :

• Concept & Feasibility : You will invent, prototype, and characterize novel devices, subsystems, and workflows for next-generation sequencing applications, with a primary focus on establishing fundamental feasibility and de-risking new technological approaches.
• Workflow Translation : You will lead the effort to translate complex, multi-step biochemical and molecular biology protocols from the benchtop onto early-stage instruments, breadboards, and custom test fixtures with novel fluidic and microfluidic systems.
• Hands-on Development & Testing : You will personally design, build, and commission custom test fixtures, breadboards, and automation scripts (e.g., Python, LabView) required for early-stage system characterization, proof-of-concept validation, and feasibility studies.
• Hypothesis-Driven Experimentation : You will design and execute rigorous, hypothesis-driven experiments to characterize system performance, pushing the boundaries of new technologies and identifying critical failure modes at the interface of biology, chemistry, and hardware.
• First-Principles Troubleshooting : You will lead early-stage, deep-dive troubleshooting efforts for complex performance issues on novel systems, seamlessly connecting systemic failures back to first-principles root causes-whether molecular, chemical, material, or physical.
• Data Analysis & Communication : You will analyze complex, multi-modal data sets, author detailed technical reports and feasibility studies, generate intellectual property, and present findings to technical teams and R&D leadership to inform technology roadmap decisions.
• Cross-Functional Collaboration : You will serve as a key technical partner to assay development scientists and hardware design engineers, providing critical, data-driven feedback to guide the co-development of reagents, consumables, and instrument hardware, ensuring that biological requirements and engineering constraints are harmonized from day one.
