Verification Engineer in Bristol

Please note this role is only open to candidates currently located in and with working rights in the UK.

Location: Preferably based at one of our UK design centres (Bristol or Cambridge).

Seniority: Engineer, Senior, Principal.

Welcome to Codasip. At Codasip, we’re redefining the future of computing. Following a bold strategic pivot toward cyber-resilient semiconductor architectures, we are building next-generation processors and systems where security is embedded at the very core by design, not as an afterthought. As we expand our portfolio of secure, CHERI-enabled technologies and focus on delivering architecture-first security solutions, there has never been a more exciting time to join. We are embarking on clean-sheet designs and expanding the teams of engineers who can establish high-quality working practices as they explore new ground. Be part of a global team shaping the next era of secure computing where innovation, ownership, and impact go hand in hand.

The impact you’ll make:

• Verify RISC-V processors and extensions
• Develop verification solutions (e.g., test benches and test bench components, stimulus generation, formal environments)
• Collaborate with other engineers in a team responsible for the delivery of all verification activities related to a component or subsystem from start to finish
• Define verification strategies for blocks and sub-systems, identifying and utilising the right tools
• Review technical specifications, providing feedback from a verification perspective
• Run simulations, hunt bugs and complete root cause analysis of complex issues
• Define, estimate, prioritise and track your own work
• Track and report verification metrics
• Craft automated verification flows

What You Bring to The Table:

• Commercial experience with functional processor verification methodologies as applied to CPU or other ASIC verification (simulators, test generation, coverage collection, gate-level simulation, etc.)
• Knowledge of verifying CPU architectures or other IP
• Fluency and the ability to write clear and concise code in languages like SystemVerilog, Python, C++, Rust, etc.
• Past verification ownership of a design block
• User knowledge of Linux to enable automation of common tasks
• Knowledge of versioning tools (Git, SVN)
• Knowledge of RISC-V Architecture
• Good knowledge of computer systems and architecture
• Analytical thinking and team collaboration skills
• Ability to work effectively across teams to debug issues and find root causes

Our UK design centres in Cambridge and Bristol, launched in early 2022, are driving innovation in cutting-edge RISC-V CPU development. We’re designing high-performance, low-power CPU cores entirely from scratch to power some of the most exciting applications. Think high-performance supercomputers and next-generation embedded systems. This is a unique chance to work on clean-sheet designs that push technological boundaries and make a real impact.

We’re looking for Verification Engineers to help bring our vision to life. You’ll be a key part of verifying complex, state-of-the-art CPUs, including advanced out-of-order processors. Taking ownership of portions of the design, you’ll apply a range of verification methodologies and play a vital role in setting high standards for a brand-new platform.

This is an opportunity to collaborate with an international team spanning Europe, working alongside world-class engineers across disciplines to solve challenges and pioneer new ideas. If you’re a bright, driven self-starter who thrives on innovation and wants to build something great, we’d love to hear from you.

Join us in Cambridge or Bristol and be part of a team redefining what’s possible in CPU design and cyber-resilient semiconductor architectures.
