A Moving Experience.

What You Will Work On

• Design and train large‑scale transformer and hybrid foundation models
• Own model architecture choices across text, multimodal, and emerging paradigms
• Diagnose and resolve training instabilities at scale
• Navigate scaling tradeoffs across data and compute
• Define the technical direction for next‑generation models

Core Responsibilities

Deep Learning & Transformer Foundations

• Apply strong fundamentals in deep learning and representation learning
• Design and modify transformer architectures, including:
• Attention variants
• RoPE, ALiBi
• Grouped Query Attention (GQA)
• Mixture‑of‑Experts (MoE)

• Lion
• Adafactor
• Learning‑rate and warmup schedulers
• Understand and debug:
• Optimiser instability
• Gradient pathologies

Scaling Laws & Compute Tradeoffs

• Apply and validate scaling laws
• Navigate Chinchilla‑style compute vs data tradeoffs
• Make informed decisions about model size, dataset size, and training duration

Loss Functions & Alignment

• Design and experiment with loss functions including:
• Next‑token prediction
• Contrastive objectives
• RLHF, DPO, GRPO
• Understand how loss design impacts convergence, generalization, and alignment

Distributed Foundation Model Training

• Design and execute large‑scale training using:
• FSDP
• ZeRO‑3
• Tensor parallelism
• Pipeline parallelism
• Apply:
• Mixed precision (bf16, fp8)
• Gradient checkpointing

Partner closely with ML systems teams
