Senior Engineer, Ethernet IP Validation

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 future of AI compute, and high-performance networking is a critical pillar of our architecture. 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.

This position is hybrid in Toronto, Canada or Santa Clara, California. We will consider Remote candidates on a case-by-case basis.

Key Responsibilities

Ethernet IP Validation

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

Bring-Up & Debug Infrastructure

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

Development & Automation

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

Minimum Qualifications

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

Nice to Have

Experience with L2/L3 networking protocols: Ethernet, IP, ARP, ICMP, VLAN, basic routing

Exposure to RTL design/verification (SystemVerilog/UVM)

Familiarity with Python-based test automation, Jenkins, or similar CI frameworks

Background working with multi-die chiplets, chip-to-chip interconnects, or high-speed board design constraints

Why Join Us?

Be a core part of shaping next-gen AI acceleration hardware

Work with a high-caliber team of silicon, systems, and software engineers

Own and influence the entire lifecycle of Ethernet IP validation – from simulation to production silicon

Help define the future of networking in AI platforms
