Senior Software Development Engineer, AWS Parallel Computing Service, AWS PCS

Are you excited about building cloud infrastructure that enables researchers, scientists, and engineers to tackle some of the world's most computationally intensive problems? The AWS High Performance Computing (HPC) team is looking for a Senior Software Development Engineer (Sr. SDE) to help advance the AWS Parallel Computing Service (PCS). This service allows customers to plan, schedule, and execute HPC workloads across the full range of AWS compute capabilities.

As a Sr. SDE on this team, you will define architectures and lead the design and implementation of critical components for systems that operate at global scale. You will collaborate with engineers across multiple AWS teams to influence the underlying services your customers depend on, drive software quality and engineering best practices, and help your team deliver reliable, performant solutions faster. If you thrive when priorities shift, enjoy working through ambiguity, and want your work to directly impact how customers run large-scale compute workloads in the cloud, we'd love to hear from you.

Key job responsibilities
- Lead the end-to-end design, implementation, and delivery of complex features for PCS, ensuring systems are scalable, maintainable, and secure.
- Own your team's architectural direction, balancing short-term delivery needs with long-term extensibility, and guide technology choices that shape the service roadmap.
- Collaborate with engineers, product managers, and partner teams across AWS to define requirements, align on system interfaces, and deliver integrated solutions.
- Drive engineering best practices across the team, including code quality, testing strategies, operational excellence, and effective use of generative AI tools to improve productivity.
- Mentor and coach other engineers through design reviews, code reviews, and hands-on guidance, raising the overall technical bar of the team.

A day in the life
Your morning might start with leading a design review for a new component, where you work through trade-offs with your team before writing a technical design document. After lunch you could be deep in code, building a prototype that validates a new approach to workload orchestration for very large clusters. Later, you join a cross-team sync with partner AWS service teams to align on an API contract. Throughout, you balance hands-on engineering with guiding teammates on their own projects, ensuring the pieces come together into a cohesive product.

About the team
