• Job title: Senior/Staff Backend Compiler Engineer
• Job type: Full Time
• Experience level: Senior
• Salary: Not specified
• Degree requirement: Postgraduate Degree
• Tech skills: Python
• Location requirements: Hybrid, United Kingdom

About the role

• Senior/Staff Backend Compiler Engineer developing a domain-specific language at Axelera AI. Collaborating with engineers across Europe to optimize workloads on heterogeneous hardware architecture.

Responsibilities

• Evolve our kernel language to something that is usable both by developers inside and outside the compiler team and company
• Design and implement backend compiler optimizations to efficiently map workloads onto heterogeneous architectures (CPU, NPU, and specialized accelerators)
• Implement advanced optimization strategies across the compiler stack based on your experience, e.g.: Memory planning, tiling, vectorization, task partitioning, concurrency optimizations (compute and memory), etc.
• Contribute to compiler infrastructure, intermediate representations, and optimization passes
• Analyze performance bottlenecks and implement improvements based on profiling and benchmarking
• Contribute to technical direction, mentor junior engineers, and promote engineering best practices
• Work effectively within a collaborative, distributed engineering team

Requirements

• Master’s or PhD in Computer Science, Computer Engineering, or a related technical field
• 5+ years of experience in compiler development, systems programming, or performance-critical backend software engineering
• Strong understanding of compiler backend concepts, including scheduling, memory optimization, and code generation
• Demonstrated experience optimizing computations at a low level (e.g., tiling, memory planning, concurrent scheduling, task synchronization)
• Basic to solid understanding of computer architecture concepts such as memory hierarchies, DMA controllers, Network-on-Chip (NoC), and modern CPU architectures (e.g., RISC-V, ARM, x86)
• Familiarity with heterogeneous computing architectures (e.g., CPU + accelerator such as GPU, NPU, DSP, or similar)
• Strong programming skills in Python and good proficiency in C++
• Experience working collaboratively in a team environment

Benefits

• Pension plan
• Extensive employee insurances
• Option to get company shares
