Staff Software Engineer

ROLE SUMMARY 

Pfizer is committed to the application of computational science in the areas of drug discovery and development and has recently initiated a large-scale migration of computational infrastructure to cloud. This role leverages extensive experience in scientific computing to deliver robust high-performance solutions supporting computational workloads across the organization.   

We are seeking an experienced individual contributor to own project migrations, user support, onboarding, documentation, communication, and training efforts related to the High-Performance Computing (HPC) environment. You will work with a team of engineers to ensure robust, scalable, high-performance cloud native infrastructure that underpins modernization of the scientific computing platform.  You will be the primary bridge between our R&D scientists and cloud infrastructure. 
 
Critical business capabilities that utilize Pfizer HPC resources include in silico drug discovery, protein folding/structure prediction, quantum chemistry, bioinformatics, pharmacokinetics and pharmacodynamics (PK/PD) modeling, ML/AI, and fluid dynamics.  Experience in one or more of these scientific domains is highly desirable.   

ROLE RESPONSIBILITIES  

• Lead solution design and migration strategy for R&D teams transitioning legacy scientific workloads to cloud based HPC platforms, ensuring alignment with performance, scalability, security, and cost objectives. 

• Partner with scientific stakeholders to translate research needs into platform level infrastructure requirements, providing senior technical guidance on compute, storage, and parallelization approaches. 

• Serve as the senior technical authority for complex HPC operational issues, defining troubleshooting frameworks, escalation paths, and long term remediation strategies for scheduler, dependency, and workflow failures. 

• Own the strategy, quality, and governance of HPC documentation and knowledge assets, ensuring documentation remains accurate, accessible, and aligned with platform standards, onboarding needs, and evolving best practices. 

• Lead platform level communications and stakeholder engagement related to HPC operations, including maintenance, capacity changes, and upgrades, ensuring transparency, predictability, and minimal disruption to scientific workloads. 

• Define and oversee user enablement and training strategy for HPC platforms, ensuring researchers are equipped to use cloud resources efficiently, responsibly, and in accordance with platform best practices.   

• Own the end to end lifecycle strategy for scientific software platforms, including selection, deployment models, upgrade planning, and deprecation, to ensure reliability, reproducibility, and broad usability across research domains. 

• Establish containerization standards and adoption models for scientific workflows, overseeing the transition of complex applications to container based execution environments and ensuring consistency across teams and platforms. 

• Set and govern application performance optimization standards across cloud instance types, guiding workload placement decisions to maximize performance, scalability, and cost efficiency. 

BASIC QUALIFICATIONS  

• B.S. with 7+ years or Ph.D. with 3+ years of experience in high performance computing, cloud computing, and life sciences. 

• Deep Linux systems expertise supporting the design, standardization, automation, and reliable operation of scientific computing platforms and services.  

• Excellent written and verbal communication skills with the ability to clearly communicate complex technical concepts to scientific, technical, and platform stakeholders. 

• Demonstrated ability to lead resolution of complex technical issues while providing clear status updates and communication back to scientific stakeholders. 

• Deep foundational technical expertise across HPC and cloud platforms, including Linux, Slurm, Kubernetes, GitOps, Google Cloud Platform, Spack, Cluster Toolkit, infrastructure-as-code
