Job summary

Openchip & Software Technologies S.L. is seeking a compiler-focused engineer to extend LLVM/MLIR/GCC-based toolchains for novel hardware accelerators in Barcelona. You will work across ML/AI and hardware teams to map workloads to features and contribute to end-to-end compiler pipelines.

The role requires strong C/C++ skills, 1–4 years’ experience with compiler frameworks, and a proactive, collaborative mindset in a hybrid work setup. Flexible schedule and competitive compensation offered.

Qualifications

• Bachelor or Master’s degree in a relevant field.
• Experience in the relevant field (1-4yr).
• Experience with compiler frameworks (e.g., LLVM, MLIR, GCC...).
• Experience with computation and parallelism APIs (CUDA, OpenAcc, OpenCL, OpenML, SYCL...).
• Solid knowledge of the C and C++ programming languages.
• Experience with code benchmarking, debugging, profiling, and tracing.
• Experience with standard tools for source control (git), continuous integration, task management (Jira).

Responsibilities

• Make independent technical contributions to help their team deliver its commitments.
• Write code to extend compiler frameworks (e.g., GCC, LLVM), enabling usage of novel hardware features and acceleration, and improving the quality of code generated for these targets.
• Interact with ML/AI and hardware teams, connecting requirements and offerings, influencing hardware/software co-design.
• Collaborate with colleagues through code reviews, bug triaging, design documents, and more.
• Contribute to shared team responsibilities (CI failure triaging, documentation, code fixits, rotations...).

Job description

The Role

The Compilers team is developing the compilers, both for traditional languages (C, C++, Fortran) and for ML frameworks. Building on top of industry-standard compiler frameworks like LLVM, your role is to develop the components that will enable the use of Openchip's novel hardware features and accelerators, bringing visible improvements to end users.

Key Responsibilities

• Make independent technical contributions to help their team deliver its commitments. In particular:

  • Write code to extend compiler frameworks (e.g., GCC, LLVM), enabling usage of novel hardware features and acceleration, and improving the quality of code generated for these targets.
  • This includes both "traditional" (high-level language to binary) compilers as well as those manipulating ML intermediate representations (e.g., model graphs).

• Interact with colleagues across projects to unblock issues, or to reach consensus on technical topics. In particular:

  • Work with ML/AI and hardware teams, connecting their respective requirements and offerings, influencing hardware/software co-design.
  • In other cases, understand ML/AI workloads, both industry standard ones and those of specific clients of the company, and map them to hardware features.
  • Collaborate with colleagues through code reviews, bug triaging, design documents,...
  • Contribute to shared team responsibilities (CI failure triaging, documentation, code fixits, rotations...).

Required Qualifications

• Bachelor or Master's degree in a relevant field.
• Experience in the relevant field (1-4yr).
• Experience with compiler frameworks (e.g., LLVM, MLIR, GCC...).
• Experience with computation and parallelism APIs (e.g., CUDA, OpenAcc, OpenCL, OpenML, SYCL,...).
• Solid knowledge of the C and C++ programming languages.
• Experience with code benchmarking, debugging, profiling, and tracing.
• Experience with standard tools for source control (git), continuous integration, task management (Jira).

Soft Skills

• Team player: communicative and collaborative person who focuses on the outcome of the team above the individual needs.
• Curious about learning new technologies/stacks.
• Capable of within- and cross-team collaboration at the technical level.
• Can-do attitude, proactive and willing to step up and resolve any obstacle. Self-aware, self-starter, and self-motivated.

Preferred Qualifications

• Experience with the Python programming language.
• Experience with lower-level development (e.g., device drivers).
• Experience with ML model training and evaluation.
• Experience with ML frameworks (e.g., TensorFlow, PyTorch, Keras,...) and runtimes (e.g., ONNX, TfLite,...)
