Engineer, Validation- GDDR7
Tenstorrent
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.
At Tenstorrent, we’re building the next generation of AI/ML hardware platforms, and next generation high speed memory is a key enabler of our performance and scalability. We are looking for a GDDR7 IP Validation and Firmware Engineer to work on the validation and enablement of our next-gen GDDR7 PHY and controller IP. In this role, you will own the post-silicon validation of high-speed memory interfaces, do low-level firmware development for bring-up and diagnostics, and work closely with cross-functional teams and memory vendors to deliver robust and high-performance memory subsystems.
This role is hybrid, based out of Toronto, Canada or Santa Clara, California.
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:
- Lead post-silicon validation of GDDR7 PHY and controller IP, including bring-up, debug, and full coverage closure.
- Develop and execute validation plans based on JEDEC specs and system use cases; perform PVT testing, SI/PI margin analysis, and compliance validation.
- Design and implement firmware tools to support link training, diagnostics, and calibration flows.
- Build automated lab test infrastructure for data capture, regression, and stress testing using scripting (e.g., Python, Shell).
- Collaborate with IP vendors, DRAM partners, and internal teams on training algorithms and debug strategies.
- Partner with cross-functional teams to resolve system-level issues, support reliability validation, and enhance memory subsystem performance.
Experience & Qualifications:
- Bachelor’s or Master’s in Electrical or Computer Engineering with experience in high-speed memory interface validation and embedded firmware development.
- Strong programming skills in C/C++ for embedded platforms.
- Experience with memory technologies such as GDDR7, GDDR6, DDR5, LPDDR5, or HBM.
- Proficiency in scripting languages (e.g., Python, Shell Scripting) for automation and lab tooling.
- Deep understanding of JEDEC memory interface standards and PHY-level training flows.
- Hands-on experience with lab tools and test equipment such as oscilloscopes, BERTs, logic analyzers, and protocol decoders.
- Proven ability to debug hardware/firmware interaction in silicon and system-level environments.
- Experience with margining, calibration, or stress-mode validation.
- Familiarity with reliability testing methodologies for memory interfaces.
- Exposure to simulation or emulation-based pre-silicon validation.
- Background working with memory vendors on compliance and feature integration.
- Exposure to low level FW development for RISC-V.
Tenstorrent offers a highly competitive compensation package and benefits, and we are an equal opportunity employer.
