Sr. Network Engineer

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.

As our AI infrastructure continues to scale, we're looking for a Network Engineer to help design, deploy, and operate the networking backbone powering Tenstorrent's global AI compute infrastructure. You'll play a critical role in ensuring the reliability, performance, and scalability of our data center networks while partnering closely with hardware, systems, and software teams to support next-generation AI clusters.

This role is hybrid, based out of Toronto, Canada.

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.

• Experienced in designing, deploying, and operating large-scale data center networks using modern leaf-spine architectures with strong Layer 2/Layer 3 networking expertise (BGP, EVPN-VXLAN, OSPF, TCP/IP).

• Hands-on experience with enterprise networking platforms including Arista (EOS), Dell (SONiC), Cisco (IOS-XE), Fortinet firewalls, and lossless Ethernet fabrics for RDMA (RoCEv2, PFC, ECN, DCQCN).

• Proven ability to troubleshoot complex production network issues across switches, routers, firewalls, and distributed infrastructure with a focus on reliability and performance.

• Skilled in network automation using Python, Ansible, Terraform, or similar tools to improve operational efficiency and scalability.

What We Need

• Design, deploy, and manage Tenstorrent's global data center network infrastructure supporting AI accelerator clusters and production environments.

• Configure, maintain, and troubleshoot switches, routers, firewalls, and high-speed network fabrics to ensure reliable, high-performance operations.

• Collaborate with hardware, platform, DevOps, and infrastructure teams to support new cluster deployments, network expansions, and performance optimization.

• Build scalable, secure, and highly available network architectures while driving automation, operational best practices, and continuous improvements in network provisioning and management.

• Gain hands-on experience building and operating networking infrastructure for next-generation AI accelerator systems and large-scale compute clusters.

• Develop expertise in high-performance data center networking technologies, including AI fabrics, high-speed Ethernet, and cloud connectivity.
