Job summary

Samsung Electronics America’s Global Ecosystem Team (GOST) is offering an internship to develop systems software for memory and storage pools that support reinforcement-learning post-training of large language models. The work explores rollout generation, reward evaluation, policy updates, and checkpoint recovery utilizing shared resources.

Based in our San Jose headquarters with daily onsite presence, you’ll build a prototype using fabric-attached memory and SSD pools, integrate with an RL

Qualifications

• Pursuing higher degree in CS with remaining academic term.
• Must have at least 1 academic term remaining.
• Proficiency in C, C++, or Rust with Python/shell scripting for experiments/automation.
• Strong understanding of OS, memory mgmt, concurrency and computer architecture.
• Experience developing and debugging on Linux, using Git, and communicating technical results.

Responsibilities

• Profile the RL post-training loop to identify memory-capacity limits, data-transfer overhead, storage stalls, and GPU idle time.
• Develop one runtime feature that coordinates bounded memory staging, asynchronous storage writes, prefetching, or capacity allocation across workers.
• Integrate the feature with an existing RL framework using its training and checkpoint interfaces.
• Preserve snapshot consistency, policy-version provenance, buffer ownership, and durable checkpoint publication during asynchronous operations.
• Compare memory-only, storage-only, and combined pool configurations using training throughput, GPU-hours, local-memory usage, and restart performance.
• Deliver correctness tests, reproducible experiments, design documentation, and code suitable for review and potential open-source contribution.
• Find the resource management issue on post-RL workload and resolve the issue in host OS.
• Complete other responsibilities as assigned.
• Complete other responsibilities as assigned.

Job description

To provide the best candidate experience amidst our high application volumes, each candidate is limited to 10 applications across all open jobs within a 6-month period.

Advancing the World’s Technology Together

Our technology solutions power the tools you use every day--including smartphones, electric vehicles, hyperscale data centers, IoT devices, and so much more. Here, you’ll have an opportunity to be part of a global leader whose innovative designs are pushing the boundaries of what’s possible and powering the future.

We believe innovation and growth are driven by an inclusive culture and a diverse workforce. We’re dedicated to empowering people to be their true selves. Together, we’re building a better tomorrow for our employees, customers, partners, and communities.

What You’ll Learn

• Project Overview: Develop systems software for memory and storage pools that support reinforcement-learning post-training of large language models
• Skills You’ll Learn:
  • Core Linux kernel memory management for virtual machines
  • How to modify the Linux kernel memory/storage management subsystem
  • Contributing to the largest open source project in the world
  • Understand how open-source SW impacts Samsung business
  • Collaborating across team, Samsung, and industry

What You’ll Do

The Samsung Global Ecosystem Team (GOST) is seeking an intern to develop systems software for memory and storage pools that support reinforcement-learning post-training of large language models. The work will examine how rollout generation, reward evaluation, policy updates, and checkpoint recovery use shared resources. You will build a focused prototype using fabric-attached memory and SSD pool, and measure its effect on training progress, memory pressure, and recovery time.

GOST consists of a geographically distributed group of engineers making high impact contributions both in software and leadership to open ecosystems such as the Linux kernel and QEMU. This work supports Samsung’s latest storage and memory technologies.

As an intern, you will contribute to the SW ecosystem R&D efforts targeting Samsung’s latest memory and storage technologies globally through distributed open-source projects. The goal of the internship is to deliver a working memory-to-storage data path, a live RL post-training demonstration, and a measured explanation of when pooling improves training efficiency or recoverability.
