Tenstorrent is leading the industry on cutting-edge AI technology, revolutionizing performance expectations, ease of use, and cost efficiency. With AI redefining the computing paradigm, solutions must evolve to unify innovations in software models, compilers, platforms, networking, and semiconductors. Our diverse team of technologists have developed a high performance RISC-V CPU from scratch, and share a passion for AI and a deep desire to build the best AI platform possible. We value collaboration, curiosity, and a commitment to solving hard problems. We are growing our team and looking for contributors of all seniorities.
CPU Memory Systems RTL Lead will drive the development of Tenstorrent’s next-generation CPU RTL. This position requires a deep understanding of CPU design including Architecture, RTL, Design Verification, Physical Design Flow. The ideal candidate will drive the team building, the microarchitecture specification, RTL design, and verification.
This role is Remote, based out of The United States.
We welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting.
Responsibilities:
- Define and develop microarchitecture specifications for CPU (loadstore, data prefetch, cache coherency protocol, shared cache, etc…). The specification includes not only design, but also comprehensive analysis / strategy for verification and PPA (power, performance, area) closure.
- Define and develop interface between CPU core and external memory subsystem. This drives the definition of bus interface protocol including cache coherence protocol.
- The candidate will be responsible for the quality of RTL including design verification and PPA closure. This includes writing RTL, reviewing / refining unit verification environment, applying right RTL optimization to control PPA.
- To maximize the team’s output, the candidate actively uses AI tools to accelerate the CPU design process.
Experience & Qualifications:
- Bachelor's, Master's, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
- Proven track record of memsys RTL design (e.g., loadstore) for high-performance CPU.
- Deep understanding of design verification strategy and trade-offs for verification methodology (simulation, formal, various checkers, etc…). The candidate should understand how to verify if your design complies with certain memory ordering rules.
- Deep understanding of CPU microarchitecture and PPA trade-off.
- Deep understanding of memory ordering model.
- Basic understanding of AMBA CHI protocol is preferred.
- Basic understanding of RISC-V Architecture is preferred.
- Proficiency in hardware description languages (HDLs) such as Verilog or VHDL.
- Excellent problem-solving abilities and analytical skills.
- Strong communication skills, with the ability to convey complex technical concepts to diverse audiences.
- Ability to work collaboratively in a team-oriented environment and across multiple disciplines.
Compensation for all engineers at Tenstorrent ranges from $100k - $500k including base and variable compensation targets. Experience, skills, education, background and location all impact the actual offer made.
Tenstorrent offers a highly competitive compensation package and benefits, and we are an equal opportunity employer.
This offer of employment is contingent upon the applicant being eligible to access U.S. export-controlled technology. Due to U.S. export laws, including those codified in the U.S. Export Administration Regulations (EAR), the Company is required to ensure compliance with these laws when transferring technology to nationals of certain countries (such as EAR Country Groups D:1, E1, and E2). These requirements apply to persons located in the U.S. and all countries outside the U.S. As the position offered will have direct and/or indirect access to information, systems, or technologies subject to these laws, the offer may be contingent upon your citizenship/permanent residency status or ability to obtain prior license approval from the U.S. Commerce Department or applicable federal agency. If employment is not possible due to U.S. export laws, any offer of employment will be rescinded.
