About the job
Tenstorrent is seeking a senior High Speed Interconnect / Signal Integrity Engineer to design and validate high-bandwidth links for large-scale AI systems. You will define, model, and qualify interconnect solutions across copper and optical technologies for next-generation AI inference and training clusters.
Responsibilities
Define and specify high-speed interconnect architectures between systems within large AI clusters.
Develop requirements, validation plans, and test strategies for passive and active copper cables and optical transceivers at 100G, 400G, 800G, and 1.6T.
Document topologies, routing assumptions, and cable requirements for internal and customer-facing clusters.
Perform link and channel budget analysis, including loss, jitter, eye margin, and BER considerations across PVT and aging.
Lead and execute qualification and reliability testing, including accelerated life testing, mating life, and failure analysis for interconnect components.
Interface with key industry suppliers, track their roadmaps, and align Tenstorrent’s system designs to future interconnect capabilities.
Qualifications
Minimum
An experienced electrical engineer with a Bachelor’s or Master’s in Electrical Engineering.
5+ years working on high-speed communications (100G–1.6T), including signal integrity, channels, and links.
Comfortable building and owning link and channel budgets and making clear tradeoffs between reach, loss, BER, and margin.
Hands-on with SI tools and lab equipment such as Keysight ADS, VNAs, TDRs, BERTs, and protocol analyzers.
Familiar with cable specification and testing, as well as accelerated life testing, mating life, and failure analysis.
Able to collaborate across hardware, systems, and manufacturing teams.
Preferred
manufacturing/DFM/DTM experience is a plus.
