Senior Cloud Engineer

Senior Cloud Engineer (Onsite Lead / Architect - AWS HPCOps) is responsible for designing, implementing, and managing large-scale high-performance computing (HPC) platforms on AWS for scientific and research-driven workloads. This role provides architecture oversight, technical leadership, and hands-on engineering support, while ensuring operational excellence and strategic alignment with enterprise goals.

As the onsite lead, you will guide a distributed engineering team, collaborate with scientific and IT stakeholders, and introduce emerging technologies that enhance HPC scalability, reliability, and automation. The role requires deep expertise in AWS HPC architecture, strong leadership capabilities, and the ability to operate autonomously in complex environments.

• Architect scalable HPC solutions using AWS Parallel Cluster, AWS Batch, EC2 Spot, Auto Scaling, and other core AWS services
• Design computing environments supporting computational chemistry, molecular dynamics, genomics, and high-throughput scientific workloads
• Develop and optimize data storage solutions using S3, EFS, FSx for Lustre, and high-performance data access patterns

• Lead onsite activities and manage a team of ~10 offshore HPC/cloud engineers
• Drive the planning, execution, integration, and operationalization of HPC projects
• Ensure delivery quality, cost efficiency, and alignment with enterprise cloud strategy

• Oversee cluster operations, job scheduling (Slurm), compute scaling, patching, and incident response
• Implement best practices for observability using Cloud Watch, Prometheus, Grafana, and logging frameworks
• Ensure high availability, reliability, and performance of HPC workloads and underlying infrastructure

• Build infrastructure using Terraform and Cloud Formation with fully automated IaC delivery pipelines
• Deploy cloud-native automation for cluster lifecycle management, cost optimization, and environment provisioning

• Lead PoCs to evaluate new HPC frameworks, containerization strategies (Docker, Singularity), and workflow engines (Nextflow, Cromwell)
• Recommend architectural enhancements and modernization approaches

• Communicate architecture, progress, risks, and recommendations to technical and non-technical stakeholders
• Collaborate with scientific computing, research, security, and enterprise architecture teams
• Act as a trusted advisor to business partners on HPC and cloud-enabled computing

• Deep experience designing HPC systems on AWS (Parallel Cluster, Batch, EC2 Spot, FSx for Lustre)
• Strong Linux administration and troubleshooting skills
• Expertise in parallel computing technologies (MPI, OpenMP), job schedulers (Slurm), and distributed systems

• Strong Terraform and Cloud Formation experience
• Hands-on CI/CD experience (Git Hub Actions, Git Lab CI, Jenkins)
• Experience managing multi-account AWS org structures

• Skilled in tuning compute, storage, and network performance for HPC workloads
• Strong knowledge of cost optimization strategies for large cluster deployments

• Ability to simplify complex HPC/cloud architectures for broader audiences
• Strong cross-functional influence and stakeholder management skills

• Proven ability to lead onsite/offshore teams, mentor engineers, and guide architecture decisions
• Able to work across regions, functions, and cultures
• Excellent written and verbal communication skills
• Demonstrates a mindset of diversity, inclusion, and continuous learning
• Inspires collaboration, accountability, and innovation

• Makes high-impact architectural and operational decisions independently
• Incorporates diverse stakeholder input to develop robust solutions
• Drives rapid and high-quality implementation of technical strategies
• Accountable for architecture governance, delivery quality, and risk mitigation

• Represents HPC function in customer meetings, architecture…
