Job Description:

Software Engineer, C++ Systems

Location: On-site San Francisco, CA

About the Role

Were 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.

Youll play a critical role in scaling our platform as we serve a rapidly growing customer base, owning production systems from day one and tackling technically demanding challenges at the forefront of GPU infrastructure.

What Youll Do

• 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

Required Experience

• 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

Technical Skills

• 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

Education

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

Soft Skills

• Ability to deliver high-quality output quickly in an early-stage startup environment
• Comfortable taking full ownership of critical production systems
• Thrives in ambiguous, high-impact problem spaces

Company & Opportunity

• 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: productmarket 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
• Expect ownership, impact, and problems that demand top 0.1% technical skill

Why This Role

If you love squeezing performance out of low-level systems, enjoy working at the intersection of GPUs, distributed systems, and production infrastructure, and want to help scale a breakthrough platform at an early stage, this role offers a rare and exciting opportunity.
