About this role

Based in Paris, France, the Agentic Compiler Engineer position at Kog involves developing the AGCO agentic compiler to optimize large language model execution across standard datacenter GPUs. This role suits engineers with deep technical expertise in compilers, GPU systems, or LLM inference who want to work on core technology within a small team.

Role Overview

The Agentic Compiler Engineer will focus on AGCO, a system designed to explore optimization strategies for LLM execution, generate changes, compile them, verify correctness, and measure performance on real hardware. Responsibilities and focus areas are tailored to the individual's background and interests while collaborating with a full-stack engineering team.

Key Responsibilities

Design compilers and intermediate representations to represent and transform LLM computations.
Build optimization passes, lowering mechanisms, and code generation routines.
Develop search methods to evaluate different implementations and execution strategies.
Implement verification and correctness checks for generated code modifications.
Execute, profile, and optimize performance on GPUs.
Work on LLM inference across operators, memory, parallelism, and communication.
Create optimization loops that connect generated changes to hardware measurements.

Requirements

Demonstrate deep technical expertise and original work in at least one area relevant to the AGCO project.
Bring background in compiler engineering, including optimization passes, IRs, lowering, code generation, LLVM, or MLIR.
Show experience with GPU programming using CUDA, HIP, Metal, Vulkan, or similar technologies.
Possess GPU performance experience involving kernels, memory, synchronization, profiling, or hardware behavior.
Understand LLM inference engines and performance optimization, including attention, MoE, parallelism, or communication.
Have knowledge of formal verification, equivalence checking, SAT/SMT, or related methods.
Understand systems designed to automatically generate, search, test, benchmark, or optimize code.
Ability to relocate to Paris and work closely with the team on-site.
