Creating a world where we all have more time with the people we love. That’s what makes us Roche. We are seeking an architect-level Principal Software Engineer to lead the software evolution of Roche’s proprietary sequencing technology, SBX. In this role, you will bridge the gap between experimental data science and industrial software engineering. While you will still engage with the "science" of DNA sequencing, your primary mandate is to engineer the systems that make that science scalable, reproducible, and fast. You will serve as the Technical Lead for a hybrid squad, driving the transition of experimental AI/models from Jupyter notebooks into robust, version-controlled, and highly optimized production libraries running on high-performance infrastructure. You will define the software architecture for SBX data analysis. You are not just analyzing data; you are building the engine that processes it. You will ensure that our basecalling and sequencing algorithms are not only accurate but are also performant, maintainable, and deployable at scale. The Opportunity Define and enforce software engineering standards, including clean code practices, comprehensive unit/integration testing, and mandatory code reviews within the data science team. Develop modular and extensible software libraries for DNA analysis, separating algorithmic logic from infrastructure code. Implement and oversee continuous integration and deployment pipelines to automate testing and streamline research code release cycles. Optimize performance of Python/PyTorch codebases, reimplementing critical bottlenecks in C++ and CUDA for GPU cluster efficiency. Convert theoretical bioinformatics concepts into highly efficient production-ready code. Design and implement solutions for effective memory management and I/O operations, tailored for large-scale genomic datasets. Build infrastructure for managing model versioning, registries, and monitoring for streamlined machine learning workflows. Design low-latency inference serving architectures for deploying deep learning models in production environments. Promote and implement containerization tools like Docker and Singularity for consistent execution environments across research and production. Architect distributed computing workflows and pipelines using tools like Nextflow and Airflow, ensuring production-grade performance and reliability in computational workflows. Develop dynamic workload managers and submission scripts to optimize resource use on SLURM-managed HPC clusters. Who you are Ph.D. or Master’s in Computer Science, Software Engineering, Bioinformatics, or related technical field. 7+ years (with PhD) or 5+ years (with MS) of industrial experience related to productionizing ML models or building scientific software. Expert-level proficiency in Python (OOP, design patterns) and strong proficiency in a compiled language C/C++. Deep understanding of data structures and algorithmic complexity. Proven experience deploying Deep Learning models (PyTorch/TensorFlow) into production. Familiarity with ONNX, TensorRT, or model quantization is a plus. Advanced knowledge of Linux internals, shell scripting, and container orchestration. Experience managing workloads on HPC (SLURM) or Cloud (AWS/GCP) environments. Production experience with Nextflow, Airflow Preferred Qualifications: Experience writing CUDA kernels or using GPU-accelerated libraries (CuPy, RAPIDS) for signal processing. Background in processing time-series data or electrical signal data. Relocation benefits are not available for this posting. The expected salary range for this position based on the primary location of Mississauga is 136,936.00 and 179,728.50 of hiring range. Actual pay will be determined based on experience, qualifications, and other job-related factors as determined by the company.
