Job description

Openchip is building exciting new RISC-V chips with HPC and AI acceleration. 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.

Openchip is building exciting new RISC-V chips with HPC and AI acceleration. 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 (5-10yr).
• 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,...)

What do we offer?

• Join an innovative team and experience company growth.
• We believe in investing in our employees and providing them with the opportunities they need to grow and develop their careers.
• Enjoy a hybrid work environment.
• We also offer flexible schedule.
• We offer a remuneration that values your experience.
• The position will have the base in Barcelona.

We are looking for outstanding people willing to join our mission to change this industry and help to build a better world.

At Openchip & Software Technologies S.L., we believe a diverse and inclusive team is the key to groundbreaking ideas. We foster a work environment where everyone feels valued, respected, and empowered to reach their full potential – regardless of race, gender, ethnicity, sexual orientation, or gender identity.
