RISC-V AI Software Engineer — Kernels, Runtime & SDK

OverviewMentium Technologies Inc. is seeking a motivated RISC-V Software Engineer to join our hardware-software co-design team. In this role, you will help develop and optimize the software stack for our custom RISC-V-based vision AI accelerator.You will work across embedded software, computer architecture, and machine learning to develop high-performance compute libraries, runtime components, and developer-facing SDK tools. A key part of the role will be efficiently mapping AI and signal-processing workloads onto a multicore RISC-V SoC, with particular attention to vector processing, memory usage, data movement, and parallel execution.You will collaborate closely with RTL design, system architecture, software, and machine learning teams. This role is well suited for an engineer with experience in RISC-V, embedded computing, or accelerator research who is interested in turning advanced architectural concepts into a practical and extensible software platform.Key ResponsibilitiesDevelop and optimize software kernels for machine learning and signal-processing workloads on a RISC-V-based acceleratorBuild reusable compute libraries, runtime components, and APIs for the Mentium SDKOptimize software for vector execution, multicore processing, and the SoC memory hierarchyDevelop efficient data-movement and workload-scheduling strategiesProfile workloads and identify compute, memory, and system-level performance bottlenecksIntegrate optimized software components into AI model deployment and inference workflowsDevelop functional tests, performance benchmarks, examples, and SDK documentationCollaborate with hardware engineers to validate architectural features and improve system performanceContribute to the continued development of the RISC-V accelerator software architecture and programming modelEvaluate and adapt relevant open-source libraries, runtimes, and compiler technologiesRequired QualificationsMaster’s or PhD degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field3+ years of combined relevant industry, doctoral research, or applied research experienceStrong programming skills in Python, C and C++Experience with Python for testing, automation, tooling, or application developmentSolid understanding of computer architecture, memory systems, and parallel processingExperience with performance optimization, profiling, and low-level debuggingFamiliarity with machine learning or signal-processing operations such as convolution and matrix multiplicationAbility to read hardware specifications and collaborate effectively across hardware and software teamsExperience with Git and standard collaborative software-development practicesProfessional proficiency in EnglishPreferred QualificationsExperience with the RISC-V instruction set or RISC-V Vector ExtensionExperience with open-source RISC-V platforms such as PULP, or similar multicore and accelerator systemsExperience with SIMD, vector processors, GPUs, DSPs, or custom accelerator architecturesExperience with vector intrinsics, assembly programming, or low-level code optimizationFamiliarity with embedded, bare-metal, or real-time software developmentExperience developing numerical, signal-processing, or machine learning librariesUnderstanding of DMA, scratchpad memory, cache hierarchies, and multicore synchronizationFamiliarity with machine learning frameworks or model formats such as PyTorch, TensorFlow, or ONNXExposure to compiler and deployment technologies such as LLVM, MLIR, TVM, Deeploy, or related toolsExperience contributing to open-source software or research software projectsExperience developing SDKs, runtime libraries, developer tools, or reusable APIsExposure to hardware-software co-design, SoC development, FPGA prototyping, or architectural simulationItalian language skills are welcome but not requiredLocation and Employment

Location: Italy-based hybrid (preferred regions: Piemonte, Lombardia, Emilia-Romagna, Veneto, Campania) Work arrangement: hybridEmployment type: Full-timeGross annual salary range — RAL: €40,000–€65,000, depending on experience and technical backgroundWhy 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.
