Full-time

Inception creates the world’s fastest, most efficient AI models. Our Mercury model is the world’s fastest reasoning LLM and first commercially available diffusion LLM, delivering 5x greater speed and efficiency than today’s LLMs, with best-in-class quality.

We are the AI researchers and engineers behind such breakthrough AI technologies as diffusion models, flash attention, and DPO.

The Role We seek experienced scientists and engineers with deep expertise in pre- and mid-training large language models. You will advance our diffusion-based LLM models, developing novel training techniques and pushing the boundaries of parallel token generation.

Key Responsibilities

• Design, develop, and optimize architectures for diffusion-based language models.
• Implement innovative training objectives and loss functions for discrete diffusion LLMs.
• Research and implement techniques for controlled text generation and constraint satisfaction.
• Develop methods for multi-modal integration within the diffusion framework.
• Improve model efficiency, reduce training time, and optimize inference throughput.

Qualifications

• BS/MS/PhD in Computer Science or a related field (or equivalent experience).
• At least 2 years of experience working on ML projects in PyTorch (or equivalent), preferably in a research lab or engineering role.
• Excellent familiarity with transformers and core LLM concepts (autoregressive pretraining, instruction tuning, in-context learning, KV caching).
• Familiarity with training and inference in diffusion models.
• Experience training deep learning models at scale in distributed computing environments.

Preferred Skills

• Extensive experience training transformer-based language models from scratch.
• Knowledge of advanced training techniques (mixed precision, gradient accumulation, etc.).
• Experience with multi-modal learning and cross-modal architectures.
• Background in optimization theory and neural network architecture design.
• Experience with LLM serving frameworks like vLLM, SGLang, or TensorRT.

Why Join Inception

• Work with World-Class Talent: Collaborate with the inventors of diffusion models and leading AI researchers
• Shape Foundational Technology: Your decisions will influence how the next generation of AI products are built and used
• Immediate Impact: Join at the ground floor where your contributions directly shape product direction and company trajectory

Perks & Benefits

• Competitive salary and equity in a rapidly growing startup
• Flexible vacation and paid time off (PTO)
• Health, dental, and vision insurance
• Catered meals (breakfast, lunch, & dinner)
• Commuter subsidies
• A collaborative and inclusive culture

About Us Inception creates the world’s fastest, most efficient AI models. Today’s autoregressive LLMs generate tokens sequentially, which makes them painfully slow and expensive. Inception’s diffusion-based LLMs (dLLMs) generate answers in parallel. They are 5x faster and more efficient, while delivering best-in-class quality.

Inception was co-founded by Stanford professor Stefano Ermon, who co-invented such breakthrough AI technologies as diffusion models, flash attention, and DPO, UCLA professor Aditya Grover, who co-invented node2vec, decision transformers, and d1 reasoning, and Cornell professor and Afresh co-founder Volodymyr Kuleshov, who co-invented MDLM and Block Diffusion.

We pioneered the application of diffusion to language, with world’s first (and only) commercially available dLLM, Mercury. We are currently deploying our large-scale diffusion LLMs at Fortune 500 companies. Diffusion is the technology behind today’s image and video AI, and we’re making it the standard for LLMs as well.

Our team includes engineers from Google DeepMind, Meta AI, Microsoft AI, and OpenAI. Based in Palo Alto, CA, we are backed by A-list venture capitalists, including Menlo Ventures, Mayfield, M12 (Microsoft’s venture fund), Snowflake Ventures, Databricks, and Innovation Endeavors, and by tech luminaries such as Andrew Ng, Andrej Karpathy, and Eric Schmidt.

If you are talented, innovative, and ambitious, come help us invent the future of AI. We are an equal opportunity employer and encourage candidates of all backgrounds to apply.
