Software Engineer

About the role

We’re seeking a highly skilled Software Engineer (C++ Systems) to join our client’s team and help build the core of our GPU virtualization platform. This role is ideal for engineers who thrive on microsecond-level performance optimization, enjoy working deep in complex C++ systems, and are motivated by building foundational infrastructure that directly impacts customers.

Responsibilities

• Optimize performance of our C++ GPU virtualization library at the systems level
• Research and develop solutions for GPU oversubscription, checkpointing, and distributed GPU clusters
• Support new hardware and software architectures with a deep, end-to-end understanding of the stack
• Debug low-level systems in production environments
• Diagnose and resolve performance issues in machine learning workloads
• Collaborate closely with the CTO on advanced systems design and implementation

Requirements

• Proven experience building and operating low-level systems in production environments
• Background working with compilers, kernels, or networking protocols
• Demonstrated ability to trace and resolve performance issues across complex systems
• Expert-level C++ proficiency (Rust experience is acceptable, though primary development will be in C++)
• Experience optimizing C++ and NIC performance
• Strong systems-level debugging and performance analysis skills

Qualifications

• Degree in Computer Science or a related field from a top-tier program
• Strong academic performance (3.7+ GPA)

Skills

• Building GPU virtualization software that dramatically improves GPU efficiency
• Operating a fast-growing GPU cloud, scaling from $0 to $500K in revenue in just six months
• Backed by Y Combinator and a recently closed $4.5M Seed round
• Join as employee #5 at a pivotal moment: product–market fit validated and scaling rapidly
• Work directly with the CTO on systems challenges few startups get to tackle
• This is a hardcore C++ systems role focused on GPU virtualization, performance tuning, production debugging, and advanced research

Benefits

• Ownership, impact, and problems that demand top 0.1% technical skill

Pay

• $160k - $200k

Schedule

• Full-time
