Develop and optimize software kernels for machine learning and signal-processing workloads on a RISC-V-based accelerator

Build reusable compute libraries, runtime components, and APIs for the Mentium SDK

Optimize software for vector execution, multicore processing, and the SoC memory hierarchy

Develop efficient data-movement and workload-scheduling strategies

Profile workloads and identify compute, memory, and system-level performance bottlenecks

Integrate optimized software components into AI model deployment and inference workflows

Develop functional tests, performance benchmarks, examples, and SDK documentation

Collaborate with hardware engineers to validate architectural features and improve system performance

Contribute to the continued development of the RISC-V accelerator software architecture and programming model





Evaluate and adapt relevant open-source libraries, runtimes, and compiler technologies

Required Qualifications

Master's or PhD degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field

3+ years of combined relevant industry, doctoral research, or applied research experience

Ability to read hardware specifications and collaborate effectively across hardware and software teams

Experience with Git and standard collaborative software-development practices

Professional proficiency in English

Preferred Qualifications

Experience with the RISC-V instruction set or RISC-V Vector Extension

Experience with open-source RISC-V platforms such as PULP, or similar multicore and accelerator systems

Experience with SIMD, vector processors, GPUs, DSPs, or custom accelerator architectures

Experience with vector intrinsics, assembly programming, or low-level code optimization

Familiarity with embedded, bare-metal, or real-time software development

Experience developing numerical, signal-processing, or machine learning libraries

Understanding of DMA,



scratchpad memory, cache hierarchies, and multicore synchronization

Familiarity with machine learning frameworks or model formats such as PyTorch, TensorFlow, or ONNX

Exposure to compiler and deployment technologies such as LLVM, MLIR, TVM, Deeploy, or related tools

Experience contributing to open-source software or research software projects

Experience developing SDKs, runtime libraries, developer tools, or reusable APIs

Exposure to hardware-software co-design, SoC development, FPGA prototyping, or architectural simulation

Italian language skills are welcome but not required

Location and Employment

Location: Italy-based hybrid (preferred regions: Piemonte, Lombardia, Emilia-Romagna, Veneto, Campania)

Work arrangement: hybrid

Employment type: Full-time

Gross annual salary range - RAL: €40,000-€65,000, depending on experience and technical background

Why Join Mentium?
At Mentium, you will work at the intersection of custom silicon, RISC-V software, embedded systems, and vision AI. You will collaborate directly with the engineers designing the hardware and help create the software environment used to program and deploy workloads on it.

As part of a small and focused company, your contributions will directly influence our products and technical direction. You will have the opportunity to take ownership of meaningful projects and help transform advanced RISC-V and accelerator technologies into a robust, developer-friendly software platform.

This position provides an opportunity to work on both research-oriented technical challenges and production-quality engineering, while gaining experience across processor architecture, optimized kernels, runtime software, AI deployment, and hardware-software co-design.
