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.\nTenstorrent is building the world’s fastest, most efficient AI compute clusters. TT-Fabric is the high-performance nervous system of this platform: the low-level networking layer that lets thousands of RISC-V and AI processors snap together into a single, massively parallel distributed supercomputer. If you love squeezing nanoseconds out of hot paths, designing protocols that move data at absurd scale, and turning messy hardware constraints into elegant distributed systems, this is an opportunity to shape the fabric that future AI models will run on\nThis role is hybrid based out of Santa Clara, CA; Austin, TX; or Toronto, ON.\nWe 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.\nWho We Are\nStrong systems engineer with deep C or C++ experience and comfort working in low-level or bare-metal environments.\nPassionate about hardware-software interaction, performance tuning, and eliminating inefficiencies at the protocol level.\nCurious about networking, synchronization, and communication across large clusters.\nComfortable reasoning from first principles and challenging industry conventions.\nMotivated by building infrastructure that directly impacts large-scale AI training and inference performance.\nWhat We Need\n\nArchitect, implement, and maintain TT-Fabric, our low-level networking library powering distributed inference and training.\nDesign scalable communication systems capable of coordinating thousands of AI processors efficiently and reliably.\nOptimize protocols, synchronization strategies, and data movement to extract maximum hardware performance.\nIntegrate TT-Fabric APIs into the broader programming model in collaboration with AI and hardware teams.\nHelp define the long-term architecture of Tenstorrent’s distributed systems stack.\nWhat You Will Learn\nHow large-scale AI clusters are architected from the networking layer up.\nThe performance characteristics of custom AI hardware and RISC-V processors at scale.\nAdvanced synchronization, collective communication, and interconnect optimization techniques.\nHow distributed systems design decisions directly influence model throughput and training efficiency.\nHow hardware and networking software co-evolve in next-generation AI infrastructure.\nCompensation for all engineers at Tenstorrent ranges from $100k - $500k including base and variable compensation targets. Experience, skills, education, background and location all impact the actual offer made.\nTenstorrent offers a highly competitive compensation package and benefits, and we are an equal opportunity employer.\nThis offer of employment is contingent upon the applicant being eligible to access U.S. export-controlled technology. Due to U.S. export laws, including those codified in the U.S. Export Administration Regulations (EAR), the Company is required to ensure compliance with these laws when transferring technology to nationals of certain countries (such as EAR Country Groups D:1, E1, and E2). These requirements apply to persons located in the U.S. and all countries outside the U.S. As the position offered will have direct and/or indirect access to information, systems, or technologies subject to these laws, the offer may be contingent upon your citizenship/permanent residency status or ability to obtain prior license approval from the U.S. Commerce Department or applicable federal agency. If employment is not possible due to U.S. export laws, any offer of employment will be rescinded.","description_format":"text","description_chars":4256,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Processors, MCUs & AI Chips","AI Chips & Accelerators","Semiconductor IP & Chip Design Services"],"lifecycle":[{"event":"open","at":"2026-08-30T14:12:36Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.099,"p_room":0.28,"age_days":584,"expected_fill_days":77,"reasons":["conf:1","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-21T05:46:15Z"},"pay":{"stated_usd_annual":500000,"is_top_pay":true},"html_url":"https://alion.io/job/tenstorrent-software-engineer-tt-fabric","json_url":"https://alion.io/job/tenstorrent-software-engineer-tt-fabric.json","meta":{"generated_at":"2026-10-21T11:43:34Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":16576,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":48241},"rest":"https://alion.io/mcp/rest/get_company?id=48241"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftenstorrent-software-engineer-tt-fabric"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Ftenstorrent-software-engineer-tt-fabric"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Ftenstorrent-software-engineer-tt-fabric"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/tenstorrent-software-engineer-tt-fabric\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftenstorrent-software-engineer-tt-fabric"}]}
