Working closely with wet-lab scientists, bioinformaticians, product teams, and software engineers, you will develop and implement robust bioinformatics solutions, integrating established community tools alongside novel methods. You will also contribute to software engineering best practices, including testing automation, CI/CD, observability, and software lifecycle management, helping to ensure DRAGEN Array software is reliable, scalable, and ready for production deployment across local and cloud-based environments.
What You'll Do
Lead the design and development of algorithms and probabilistic models for analysis of array and NGS data supporting genotyping and genetics applications.
Apply statistical, computational, and machine‑learning methods to large‑scale genetic and epigenetic datasets (e.g., genotyping, sequencing, copy number, methylation).
Design and develop production‑grade software that automates analytical workflows and enables robust analysis at scale.
Contribute to and help shape software testing automation, including unit, integration, and regression testing of bioinformatics pipelines.
Define and maintain CI/CD workflows to support continuous integration, validation, and reliable delivery of DRAGEN Array software.
Implement and evolve telemetry, logging, and monitoring to improve observability, diagnostics, and operational robustness.
Execute and improve Software Lifecycle (SLC) practices, including requirements traceability, design documentation, verification, and validation.
Use tools such as JAMA (requirements and traceability) and JIRA (planning and execution) to support structured, high‑quality software development.
Collaborate closely with wet‑lab scientists, product management, and engineering teams to translate scientific needs into validated computational solutions.
For staff level, provide mentorship and technical guidance to other scientists and engineers, and contribute to best practices in algorithm design, software engineering, and data analysis.
Why You
You will bring deep expertise in bioinformatics algorithm development, statistical modelling, and computational genomics, with experience developing production-quality software within scientific or commercial environments. You thrive working across multidisciplinary teams and are passionate about translating complex genomic data into impactful solutions that advance translational research and precision medicine.
You will have experience with array and NGS technologies, machine learning approaches, and scalable software development practices including testing automation, CI/CD, and software lifecycle management. For staff-level candidates, experience providing technical leadership, influencing scientific direction, and mentoring colleagues will be highly valued.
You'll also bring
PhD in Bioinformatics, Computational Biology, Computer Science, Biostatistics, Bioengineering, or a related field
Strong algorithm development and statistical modelling expertise
Experience with genomic data analysis at scale
Programming expertise in Python and/or R
Experience with production software development practices
Knowledge of testing automation, CI/CD and software lifecycle processes
Excellent communication and collaboration skills
