About the role

  • Foundational AI Research Scientist developing next-generation language models. Pioneering large-language-model architectures and attention mechanisms for efficient scaling.

Responsibilities

  • Research and prototype sub-quadratic attention architectures to unlock efficient scaling of large language models.
  • Design and evaluate efficient attention mechanisms including state-space models (e.g., Mamba), linear attention variants, and sparse attention patterns.
  • Lead pre-training initiatives across a range of model scales from 1B to 100B+ parameters.
  • Conduct rigorous experiments measuring the efficiency, performance, and scaling characteristics of novel architectures.
  • Collaborate closely with product and engineering teams to integrate models into production systems.
  • Stay at the forefront of foundational research and help shape Aldea's long-term model roadmap.

Requirements

  • Requires a Ph.D. in Computer Science, Engineering, or related field.
  • 3+ years of relevant industry experience.
  • Deep understanding of modern sequence modeling architectures including State Space Models (SSMs), Sparse Attention mechanisms, Mixture of Experts (MoE), and Linear Attention variants.
  • Hands-on experience pre-training large language models across a range of scales (1B+ parameters).
  • Expertise in PyTorch, Transformers, and large-scale deep-learning frameworks.
  • Proven ability to design and evaluate complex research experiments.
  • Demonstrated research impact through patents, deployed systems, or core-model contributions.
  • Nice to Have Experience with distributed training frameworks and multi-node optimization.
  • Knowledge of GPU acceleration, CUDA kernels, or Triton optimization.
  • Publication record in top-tier ML venues (NeurIPS, ICML, ICLR) focused on architecture research.
  • Experience with model scaling laws and efficiency-performance tradeoffs.
  • Background in hybrid architectures combining attention with alternative sequence modeling approaches.
  • Familiarity with training stability techniques for large-scale pre-training runs.

Benefits

  • Competitive base salary
  • Performance-based bonus aligned with research and model milestones
  • Equity participation
  • Flexible Paid Time Off
  • Comprehensive health, dental, and vision coverage
