About Us

Together.ai is at the forefront of AI infrastructure development, creating robust platforms and frameworks to support state-of-the-art large-scale machine learning training. We specialize in delivering resilient, high-performance systems that power breakthroughs in AI research and deployment.

We are seeking a Large-scale Training Resilience Engineer to ensure the reliability, fault tolerance, and scalability of our large-scale training infrastructure. If you are passionate about solving complex distributed systems problems and building highly available AI training pipelines, this role is for you.

 

Responsibilities

• Resilience and Fault Tolerance Design:
  • Develop systems to identify, isolate, and recover from failures in large-scale distributed training workloads.
  • Implement proactive error-detection mechanisms, including straggler detection and fault prediction algorithms.
• Distributed System Optimization:
  • Ensure stability and consistency across distributed training clusters (e.g., GPU/TPU clusters).
  • Optimize recovery time and throughput in the face of hardware or software failures.
• Monitoring and Observability:
  • Design and maintain observability systems for monitoring cluster health, training performance, and failure patterns.
  • Leverage telemetry data to improve incident response and automate mitigation strategies.
• Automation and Tooling:
  • Build resilience-focused tooling, such as job health monitors, distributed checkpoint systems, and automated recovery workflows.
  • Enhance debugging and diagnosis frameworks for distributed training jobs.
• Collaboration and Documentation:
  • Collaborate with platform engineers, researchers, and ML practitioners to identify pain points and resilience requirements.
  • Document and communicate best practices for fault-tolerant AI training.

 

Qualifications

Must-Have:

• Experience:
  • 5+ years of experience in distributed systems, cloud infrastructure, or large-scale machine learning training.
• Technical Skills:
  • Proficiency in distributed computing frameworks (e.g., PyTorch DDP, TensorFlow, Horovod).
  • Strong knowledge of resilience strategies in distributed systems (e.g., leader election, consensus, retry mechanisms).
  • Hands-on experience with observability tools (e.g., Prometheus, Grafana, ELK stack).
• Programming:
  • Proficient in Python, Go, or a similar programming language.
• Infrastructure:
  • Experience working with cloud platforms (e.g., AWS, GCP, Azure) and Kubernetes for workload orchestration.
• Soft Skills:
  • Strong analytical, problem-solving, and debugging skills.
  • Excellent collaboration and communication skills.

Nice-to-Have:

• Familiarity with GPU/TPU cluster management and scheduling.
• Experience with high-availability database systems or message queues.
• Experience with open-source contributions or community engagement.
