Position Overview

We are looking for a Frontend / Graph-level Compiler Engineer to join our growing compiler team at Axelera AI. In this role, you will play a key part in developing and optimizing our MLIR-based compiler stack, enabling efficient execution of AI workloads on cutting-edge heterogeneous hardware architectures.

You will work closely with AI researchers, compiler engineers, and hardware architects, collaborating with a talented team of engineers across Europe. This is your chance to work on cutting-edge AI acceleration architectures, advance compiler technology, and make a real impact in a fast-moving startup environment.

Key responsibilities:

• Design, implement, and maintain frontend and graph-level compiler components using MLIR

• Develop and optimize graph-level transformations such as operator fusion, constant folding, operator sinking, graph partitioning, and other performance-critical optimizations

• Extend and maintain MLIR dialects, passes, and infrastructure to support AI workloads

• Integrate and lower AI models from frameworks such as PyTorch, ONNX, and TensorFlow into internal compiler representations

• Collaborate with hardware and backend compiler teams to ensure efficient mapping of AI workloads to heterogeneous architectures

• Support and mentor team members in adopting and effectively using MLIR infrastructure

• Analyze model graphs and implement optimizations to improve performance, memory efficiency, and execution efficiency

• Contribute to the design and evolution of the overall compiler architecture and tooling

• Debug, profile, and improve compiler performance and correctness

Qualifications:

• Master’s or PhD in Computer Science or a related technical field

• 3-5 years of experience in a Software Engineering role, thereof ideally 2 years of experience with Deep Learning frameworks and AI systems

• Experience with MLIR, including dialects, passes, and compiler infrastructure

• Solid understanding of compiler design principles and intermediate representations, especially graph-based Irs

• Experience working with AI model frameworks such as PyTorch (preferred), ONNX, or TensorFlow

• Proven experience implementing graph-level optimizations such as operator fusion, constant folding, graph partitioning, or similar transformations

• Strong programming skills in C++ and Python

• Experience working in collaborative engineering teams

• Excellent communication skills and willingness to share knowledge and mentor others

Nice to have:

• Experience working with custom AI accelerators or specialized hardware

• Background in computer architecture, especially heterogeneous systems (e.g., CPU + NPU, GPU, or dedicated accelerators)

• Experience with AI compiler stacks such as Torch-MLIR, TVM, XLA, Glow, or similar

• Experience optimizing AI workloads for performance and efficiency

• Familiarity with frontend model ingestion, graph lowering, and compiler pipelines

Location

We offer a flexible working arrangement, with options to:

• Work from one of our Axelera AI offices (Leuven in Belgium, Amsterdam and Eindhoven in the Netherlands, Zurich in Switzerland, Florence and Milan in Italy or Bristol in the United Kingdom) if you're already based in the vicinity.

• Work fully remotely from any European country (incl. the UK) you are already in.

• Relocate with us and work from Italy (Florence or Milan) or the Netherlands (Amsterdam or Eindhoven).

Kindly note that priority will be given to candidates who are [interested in being] based in Belgium or Italy.
