About the role

About the Role

We’re looking for an ML Engineer focused on training optimization to help us scale and improve large-scale model training. You’ll work at the intersection of research and production, optimizing training pipelines for speed, stability, and cost—while collaborating closely with researchers pushing model architecture and capability forward.

  • This is a high-impact role with real ownership: your work directly affects how fast we can iterate, how large we can scale, and how efficiently we deploy new models.

What You’ll Do

  • Optimize large-scale model training pipelines (throughput, convergence, stability, and cost)
  • Improve distributed training strategies (data, model, and pipeline parallelism)
  • Tune optimizers, schedulers, batch sizing, and precision (bf16 / fp16 / fp8)
  • Reduce training time and compute cost via profiling, bottleneck analysis, and systems-level improvements
  • Collaborate with researchers on architecture-aware training strategies
  • Build and maintain robust training infrastructure (checkpointing, fault tolerance, reproducibility)
  • Evaluate and integrate new training techniques (e.g. gradient checkpointing, ZeRO, FSDP, custom kernels)
  • Own training performance metrics and continuously push them forward

What We’re Looking For

  • Strong experience training large neural networks (LLMs or similarly large models)
  • Hands-on experience with training optimization (not just model usage)

Solid understanding of

  • Backpropagation, optimization algorithms, and training dynamics
  • Distributed systems for ML training
  • Experience with PyTorch (required)
  • Comfort working close to hardware (GPUs, memory, networking constraints)
  • Ability to move fluidly between research ideas and production-ready code

Nice to Have

  • Experience with large-scale distributed training (multi-node, multi-GPU)
  • Familiarity with DeepSpeed, FSDP, Megatron, or custom training stacks
  • Experience optimizing training on AMD or NVIDIA GPUs
  • Contributions to open-source ML infrastructure or research codebases
  • Exposure to non-Transformer architectures (RNNs, hybrid models, etc.)

Why Join Us

  • Real ownership at Series-A stage — your work shapes the company’s trajectory
  • Work on cutting-edge models and training systems at scale
  • Small, highly technical team with fast feedback loops
  • Strong emphasis on engineering quality and research rigor
  • Competitive compensation + meaningful equity
