We've built a versatile cloud platform that eliminates infrastructure barriers, empowering builders to focus on innovation instead of fighting their stack. Because breakthrough AI should move at the speed of ideas, not infrastructure.\nAbout the Role\nWe’re seeking a Principal Network Engineer (L7) focused on owning and evolving large-scale, RoCEv2 data center networks powering next generation AI and ML infrastructure.\nYou’ll work closely with our network architect and infrastructure leadership to define how the network is designed, implemented, and operated at scale, keeping over 8,000 GPUs burring today and scaling to cluster sizes reaching over 100,000 GPUs. You will be responsible for the architectural decisions that determine performance, reliability, and operational sanity at scale.\nYou’ll remain hands-on with high-speed optics, switching, routing, and congestion management in production clusters, while also setting the standards, patterns, and tooling other engineers build and operate against.\nWhat You’ll Do\nAs a Principal Engineer, you own end-to-end network architecture, make high-impact design decisions, and set technical direction across teams, with clear examples of systems you’ve defined and scaled\n\nDefine, evolve, and standardize large-scale RoCEv2 data center networks supporting AI and ML clusters from thousands to 100,000+ GPUs\n\nSet and validate congestion management strategy across RDMA fabrics, including PFC, ECN, and DCQCN, based on real production behavior\n\nEstablish automation, validation, and observability patterns that prevent misconfiguration and eliminate manual operational work\n\nAct as the technical escalation point for complex failures, scaling limits, and architectural tradeoffs in always-on, multi-tenant environments\n\nEssential Skills & Qualifications\nBachelor’s degree in Computer Science, Electrical Engineering, or a related technical field, or equivalent practical experience\n\nDeep experience designing and operating RDMA and RoCEv2 networks in large-scale production environments supporting AI or HPC workloads\n\nExpert-level knowledge of switching hardware and their NOS, such as Arista, Juniper, and custom solutions using SONiC, including high-speed Ethernet fabrics\n\nProven hands-on experience with congestion management and performance tuning using PFC, ECN, and DCQCN\n\nStrong experience with high-speed optics and cabling including 400G, 800G, and AEC, AOC, DAC, and structured cabling at scale\n\nStrong automation mindset, with experience using Python, Ansible, Terraform, Git, and production observability tooling\n\nWe’re looking for engineers who operate comfortably at scale, make hard calls with incomplete data, and take responsibility for systems that must work under sustained load. The solutions that work on a handful of devices will not work at Exascale.\n\nWhat We Offer\nStock Options\n\n100% paid Medical, Dental, and Vision insurance for Employees\n\nCompany Health Savings Account Contributions\n\n100% paid Short Term and Long Term Disability Insurance for Employees\n\nLife and Voluntary Supplemental Insurance Options\n\nOther Insurance Options, such as Pet & Legal Insurance\n\nVarious Supplementary Health Benefits, such as discounted Virtual Healthcare Appointments and Serious Illness Support\n\nFlexible Spending Account\n\n401(k)\n\nEmployee Assistance Program\n\nFlexible PTO\n\nPaid Holidays\n\nParental Leave\n\nOther In-Office Perks\n\nEqual Employment Opportunity\nTensorWave is an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. We do not discriminate on the basis of any protected status under applicable law.\nReasonable Accommodations\nTensorWave provides reasonable accommodations in accordance with applicable laws. If you require accommodation during the hiring process, please contact .\nEmployment Eligibility\nAll offers of employment are contingent upon verification of identity and authorization to work in the United States, as required by law.\nBackground Checks\nWhere permitted by law, employment may be contingent upon the successful completion of a job-related background check.\nData Privacy Notice\nBy submitting an application, you acknowledge that TensorWave may collect, use, and retain your personal information for recruiting and employment-related purposes in accordance with applicable data privacy laws.","description_format":"text","description_chars":4502,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Parental leave","Stock options","Vision insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Platforms (IaaS & PaaS)","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-07-31T19:32:23Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":152500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":50,"band":"ok","label":"Likely open","p_open":1,"p_active":0.903,"p_room":0.55,"age_days":77,"expected_fill_days":77,"reasons":["conf:3","velocity","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/tensorwave-principal-network-engineer","json_url":"https://alion.io/job/tensorwave-principal-network-engineer.json","meta":{"generated_at":"2026-10-17T07:35:13Z","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":10258,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":6823},"rest":"https://alion.io/mcp/rest/get_company?id=6823"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftensorwave-principal-network-engineer"},{"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%2Ftensorwave-principal-network-engineer"},{"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%2Ftensorwave-principal-network-engineer"},{"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/tensorwave-principal-network-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftensorwave-principal-network-engineer"}]}
