Headquartered in Silicon Valley,
femtoAI
—formerly known as Femtosense—was founded in 2018 by researchers from the Brains in Silicon Lab at Stanford University. Our technology takes inspiration from the principles of neuromorphic computing such as sparsity to empower intelligence in everyday devices.

We pioneered a high-performance AI accelerator integrated with an end-to-end embedded AI platform, enabling low-latency operation with less energy at a fraction of the cost. From wearables and household appliances to robotics and autonomous vehicles, femto

AI brings the power of AI to everyday devices.

You will work on a custom ML compiler that transforms modern ML and DSP models into highly efficient programs for our accelerator.

This role spans the full compiler stack—from ingesting models and transforming intermediate representations to optimizing execution under tight memory and latency constraints.

• Build and maintain model ingestion pipelines (e.g., PyTorch / ONNX → internal IR)
• Implement graph transformations such as:
• Operator decomposition and canonicalization
• Shape inference and layout transformations
• Develop and extend intermediate representations (e.g., MLIR)
• Implement optimization passes including:
• Operator fusion and graph partitioning
• Basic scheduling and tiling strategies
• Memory planning and reuse
• Debug correctness and numerical issues across transformations
• Collaborate with hardware and ML teams to improve system performance

• 2+ years of experience in compilers and/or edge-AI
• Proficiency in Python and/or C++
• Experience with at least one of the following:
• MLIR, LLVM, TVM, XLA, or similar
• Graph-level transformations or ML model internals
• Understanding of deep learning models (conv, sequence models, etc.)
• Ability to reason about correctness and performance tradeoffs

• Experience with optimization techniques (tiling, scheduling, memory reuse)
• Familiarity with ONNX or PyTorch internals
• Exposure to quantization or low-precision computation
• Interest in hardware‑aware ML systems
• 401(k)
• Medical insurance
• Vision insurance
• Disability insurance
• Paid maternity leave
• Paid paternity leave
• Child care support
