How to Apply for Senior Software Engineer, GPU Cluster Infrastructure

at Far.Ai

🏢 About Far.Ai

FAR.AI is a non-profit AI research institute dedicated to ensuring advanced AI is safe and beneficial, with a unique portfolio approach that spans from early research to real-world adoption. They offer serious infrastructure for ambitious research, including a dedicated compute cluster and experiment-scaling stack, and have a strong track record of publishing at top venues like NeurIPS and ICML. Working here means contributing to a mission-driven organization that collaborates with frontier labs and governments to set new safety standards.

About This Role

As a Senior Software Engineer on the GPU Cluster Infrastructure team, you will design, build, and maintain the high-performance compute infrastructure that powers FAR.AI's AI safety research. You'll work closely with researchers to optimize experiment scaling, ensuring they can focus on breakthroughs rather than infrastructure challenges. This role is critical for enabling large-scale experiments that inform global AI safety efforts.

💡 A Day in the Life

A typical day might involve monitoring cluster health, debugging a failed training job, and working with researchers to optimize their experiment pipeline. You could also spend time automating infrastructure provisioning, evaluating new GPU technologies, and participating in team meetings to align on priorities. The role blends hands-on technical work with strategic planning to support cutting-edge AI safety research.

🎯 Who Far.Ai Is Looking For

  • Extensive experience managing large-scale GPU clusters (e.g., NVIDIA DGX, Kubernetes, Slurm) and optimizing distributed training workflows.
  • Proficiency in infrastructure-as-code (Terraform, Ansible), containerization (Docker, Kubernetes), and cloud platforms (AWS, GCP, Azure).
  • Strong programming skills in Python and Go, with a track record of building reliable, scalable systems for ML workloads.
  • Familiarity with AI/ML frameworks (PyTorch, TensorFlow) and an understanding of the unique demands of AI safety research, such as reproducibility and security.

📝 Tips for Applying to Far.Ai

1

Highlight specific experience with GPU cluster management, including scale (number of GPUs), orchestration tools, and monitoring solutions you've implemented.

2

Demonstrate familiarity with FAR.AI's research areas by referencing their published papers or projects, and explain how your infrastructure work can accelerate their mission.

3

Quantify achievements: e.g., 'Reduced training time by X% by optimizing interconnectivity' or 'Managed a cluster of Y GPUs with Z% uptime'.

4

Emphasize any open-source contributions or tools you've built for ML infrastructure, as FAR.AI values public sharing and collaboration.

5

Show awareness of the unique constraints of non-profit research, such as budget optimization and resource efficiency, and how you've addressed them.

✉️ What to Emphasize in Your Cover Letter

['Your hands-on experience designing and scaling GPU clusters for AI/ML workloads, with concrete metrics.', "How you've collaborated with researchers to understand their needs and translate them into robust infrastructure solutions.", 'Your commitment to AI safety and how infrastructure reliability directly impacts the credibility and speed of safety research.', 'Any experience with security and compliance in research environments, especially when working with sensitive models or data.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read FAR.AI's recent publications and blog posts to understand their research directions, especially any involving large-scale experiments or infrastructure.
  • → Explore their GitHub repositories (if available) to see the tools and frameworks they use or contribute to.
  • → Learn about their partnerships with frontier labs and governments to understand the real-world impact of their work.
  • → Investigate the backgrounds of the engineering team on LinkedIn to understand their expertise and potential interview style.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a GPU cluster from scratch for a research lab with a limited budget: what hardware, software, and networking would you choose and why?
2 How do you handle fault tolerance and job scheduling in a multi-tenant GPU cluster to maximize utilization?
3 Describe a time you optimized a distributed training job that was bottlenecked by I/O or communication. What tools and techniques did you use?
4 How would you ensure reproducibility of experiments across different hardware configurations and software versions?
5 Discuss your approach to monitoring and alerting for GPU clusters, including metrics you track and how you respond to common failures.

⚠️ Common Mistakes to Avoid

  • Focusing only on generic DevOps skills without demonstrating specific experience with GPU-accelerated workloads and ML frameworks.
  • Ignoring the non-profit context: candidates who emphasize profit-driven optimizations or lack awareness of resource constraints may not fit.
  • Neglecting to mention collaboration with researchers: this role requires close partnership, so failing to show teamwork skills is a red flag.
