**Please note this role is open to candidates currently located in, and with working rights to the UK or EU (especially Czechia)**

Welcome to Codasip

We believe Codasip is the most innovative processor solutions company. We take pride in designing and developing cutting-edge, high-performance, and energy-efficient CPU cores from scratch, and our own automated proprietary tools to fully customize them. We give our customers a unique competitive advantage by empowering their system-on-chip developers to build the most innovative products.

Our processor cores are based on the RISC-V open architecture. The potential for customizing RISC-V is unlocked with the Codasip Custom Compute approach: our unique architecture description language, CodAL, and the powerful automated processor design tool, Codasip Studio. These are at the heart of our unique and groundbreaking RISC-V processor solutions.

Founded in 2014, we’ve grown into a thriving and talented global community. Our IP engineering teams work from offices spread across Europe, including our first and largest design center in the beautiful city of Brno, Czechia. Across Europe, we already have design teams in Cambridge, Bristol, Munich, Villeneuve-Loubet, Barcelona, Thessaloniki, Heraklion and Athens. The Codasip team is also based close to its customers, which means we have dedicated sales and application engineers in the USA, Japan, Korea, and China.

Codasip is a private company backed by well-funded EU grants. Our products are already making a real impact, with billions of devices already in the market powered by our processor IP and tools.

What you’ll do

We’re looking for an LLVM Compiler Engineer to join our Embedded Software team and be part of realizing a whole new paradigm in semiconductors and microprocessor design. The role will initially be within our Labs organization, where we work on cutting-edge technologies and prepare them for rapid commercialization.

You will support the exploration and implementation of Vectors for Codasip RISC-V CPU cores. As we transition to commercialization, you will then work within our Studio Compiler team and ensure our highly automated design toolset has the necessary and comprehensive features for designing customizable vector architectures.

The scope of the work is broad, varied, and technically challenging.

You will:

  • Customize and optimize LLVM to support Codasip’s standard and customized embedded RISC-V CPU cores with in-pipeline and co-processor vector units
  • Enhance the compiler to work with custom hardware extensions and completely new processor architectures developed using our Studio EDA tool
  • Contribute expert advice to both internal and external customers to develop capabilities, skills and processes
  • Support the Embedded Software and Processor Design teams with compiler expertise to help optimize software and guide microarchitecture design
  • Explore compiler technology to support novel compute architectures and technologies
  • Partner with the Codasip Studio EDA tool compiler team to improve the tool’s automatically generated, LLVM-based C/C++ compiler
  • Work on both short-term customer-driven projects as well as longer-term strategic Codasip software products
  • Collaborate with the wider industry, open source community and academia to drive compiler adoption and future enhancements.
  • Work with/within our Studio compiler teams as we transition to commercialization, with scope in the future to explore further applications of this work e.g. AI/ML


What you need:

  • In-depth knowledge of and experience developing LLVM compilers
  • Strong C++ programming skills
  • Knowledge of Vector processing architectures (Scalable vectors and/or SIMD) and techniques, with experience in implementing and tuning/optimizing vector code
  • A flexible and adaptable attitude to work
  • A desire to learn and also positively influence the technical development of others
  • Lateral thinking and problem solving skills

What we’d love you to have:

  • Experience with RISC-V technologies
  • The ability to communicate effectively at both the technical and management level
  • An interest in AI/ML and/or MLIR
