Sciforium is an AI infrastructure company developing next-generation multimodal AI models and a proprietary, high-efficiency serving platform. Backed by multi-million-dollar funding and direct sponsorship from AMD with hands-on support from AMD engineers the team is scaling rapidly to build the full stack powering frontier AI models and real-time applications.

About the role

Sciforium is seeking a highly analytical and systems-aware Data Scientist to design, develop, and refine the next-generation AI models that leverage our large-scale compute clusters. In this role, you will bridge the gap between theoretical research and production-grade performance. You will not only build state-of-the-art LLMs and generative models but also ensure they are architecturally optimized for distributed training environments.

This position is ideal for a scientist who thinks deeply about algorithmic efficiency, convergence stability, and how model architecture impacts hardware utilization. You will play a pivotal role in defining the intelligence that powers Sciforium’s core offerings.

What you'll do

• Model Architecture Design: Develop and experiment with novel architectures for LLMs and generative AI, focusing on maximizing performance-per-watt and training throughput.

• Large-Scale Training Execution: Lead the end-to-end training runs of foundation models, monitoring loss curves, stability, and convergence across massive multi-node clusters.

• Optimization & Scaling Laws: Apply scaling laws to predict model performance and optimize hyperparameters, tokenization strategies, and objective functions for trillion-parameter regimes.

• Data Engineering & Curation: Build and maintain sophisticated data pipelines that handle petabyte-scale pre-training datasets, ensuring high-quality signal through advanced filtering and deduplication.

• Algorithmic Profiling: Collaborate with the Training Engineering team to profile how specific model layers (e.g., Attention mechanisms, MoE layers) interact with GPU/accelerator memory and interconnects.

• Evaluation & Benchmarking: Design robust evaluation frameworks to measure model capability across reasoning, coding, and creative tasks, ensuring alignment with safety and performance standards.

• Cross-Functional Collaboration: Partner with Infrastructure and Kernel engineers to co-design features that improve training efficiency and model FLOPs utilization (MFU).

Ideal candidate profile

• 5+ years of industry experience in Data Science, Machine Learning Research, or a closely related field, with a strong emphasis on deep learning.

• Bachelor’s or Master’s degree in Computer Science, Statistics, Mathematics, or another quantitative discipline.

• Expert-level Python skills with deep proficiency in PyTorch or JAX.

• Demonstrated experience training and deploying large-scale models (e.g., LLMs, diffusion models) in distributed production environments.

• Deep understanding of distributed training paradigms, including data parallelism, pipeline parallelism, and tensor parallelism.

• Strong mathematical foundation in linear algebra, calculus, and optimization, particularly as applied to neural network training and convergence.

• Experience working with data-at-scale tooling, such as Spark, Ray, or high-throughput data loading frameworks.

Nice-to-have

• PhD in a relevant field, with publications at top-tier conferences (e.g., NeurIPS, ICML, ICLR).

• Hands-on experience with Mixture-of-Experts (MoE) architectures, including routing and load-balancing challenges.

• Familiarity with RLHF workflows, including PPO and DPO fine-tuning pipelines.

• Knowledge of model quantization techniques (e.g., FP8, INT8, AWQ) and their impact on training stability and inference performance.

• Contributions to open-source ML libraries or involvement in high-profile LLM releases.

Benefits include

• Medical, dental, and vision insurance

• 401k plan

• Daily lunch, snacks, and beverages

• Flexible time off

• Competitive salary and equity
