Senior Engineer, Tenstorrent

• Bachelor’s or Master’s in Electrical or Computer Engineering with more than 8 years of relevant experience
• Strong embedded systems background with C/C++ (bare-metal, RTOS, or embedded Linux)
• Deep familiarity with Ethernet MAC/PHY architecture, including SerDes, PCS/PMA, link training, and packet framing
• Experience with pre- and post-silicon validation, including hands-on with traffic generators and lab equipment
• Comfortable with debugging tools and interfaces like UART, JTAG, MDIO, and analyzing packet traces

Desirable

• We’re seeking a IP Validation Engineer with deep expertise in high-speed Ethernet (400G/800G and beyond) to validate and enable the next generation of Ethernet MAC and PHY IPs that power our cutting-edge AI accelerator chips
• This role sits at the intersection of embedded systems, silicon validation, and advanced networking
• You'll work with best-in-class IP from leading vendors and in-house designs, bringing up and validating these IPs in silicon, and building robust validation infrastructure that ensures performance, interoperability, and reliability at scale
• Validate and debug high-speed Ethernet MAC and PHY IPs (400GbE/800GbE)
• Perform functional, performance, and compliance testing across PCS/PMA layers, SerDes lanes, loopbacks, and DMA engines
• Define and execute AN/LT, pause frames, CRC/FCS and fault handling tests
• Build automated validation suites using traffic generators and real-world packet scenarios
• Drive post-silicon bring-up across simulation, emulation, and lab environments, validating IPs in both controlled and real-world scenarios
• Write embedded diagnostics, bring-up scripts, and validation firmware
• Debug low-level issues using JTAG, MDIO, trace tools, and protocol analyzers
• Collaborate with RTL designers, system architects, and software teams to root-cause and resolve cross-stack issues
• Develop pre-silicon test frameworks in simulation and emulation environments
• Author and maintain low-level firmware for early hardware bring-up and validation
• Use scripting (Python, shell scripts, etc.) to automate test flows, data capture, and regression infrastructure
• Contribute to CI/CD flows for silicon validation pipelines
• Deliver production-ready routines for low-level IP initialization, link training, telemetry, and RAS diagnostics
