Join our SI team to ensure that every board we ship meets the most demanding signal integrity requirements - from early material research through high-volume manufacturing. You'll work at the intersection of electrical design, PCB fabrication science, and supplier quality, directly impacting products like DGX, MGX, and next-generation GPU/networking platforms.\nIf you love solving complex signal integrity challenges and thrive on bridging the gap between design intent and manufacturing reality, we want to hear from you.\nWhat You'll Be Doing:\nDefine board and system level SI requirements with emphasis on PCB impedance control, insertion loss budgets, and high-speed channel performance\nLead SI/PI design activities including PCB stackup definition, laminate/prepreg material selection, via impedance optimization, and design review\nEvaluate and qualify new PCB materials through characterization test vehicles, analyzing Dk, Df, surface roughness, and copper foil properties across frequency\nCollaborate with PCB fabrication suppliers to establish and monitor SI quality metrics - including trace geometry (H1/H2/W/T), impedance, and insertion loss - for both NPI and mass production builds\nDevelop and maintain statistical process control frameworks for PCB fab impedance and IL data; identify trends, excursions, and root causes\nConduct PCB supplier audits to verify process capability, compliance with NVIDIA specifications, and continuous improvement initiatives\nPartner with cross-functional teams (layout, mechanical, reliability, procurement) to balance SI performance with manufacturing feasibility, cost, and reliability\nContribute to PCB technology roadmap development, evaluating emerging materials and fabrication processes for next-generation products\nWhat We Need to See:\nBS or MS in Electrical Engineering, Materials Science, Chemical Engineering, or a related field, with 5+ years of relevant experience in PCB SI or PCB fabrication\nStrong foundation in electromagnetics, transmission line theory, and high-frequency signal propagation (skin effect, dielectric loss, dispersion)\nExperience with 3D/2D EM simulation tools such as HFSS, Q2D, Ansys SIwave, or Polar impedance calculators\nHands-on experience with lab measurement equipment including VNA and TDR for impedance and insertion loss characterization\nWorking knowledge of PCB fabrication processes: lamination, etching, plating, drilling, and their impact on electrical performance\nAbility to analyze data, identify trends, and communicate findings clearly to both technical and non-technical stakeholders\nEffective written and verbal communication skills in English\nWays to Stand Out from the Crowd:\nExperience with advanced PCB materials and technologies (e.g., PTFE/HC laminates, HVLP4/5 copper foil, TLPS, embedded capacitors)\nProficiency in Python, MATLAB, JMP, or similar tools for data analysis, automation, and statistical process monitoring\nFamiliarity with Delta-L or other de-embedding methodologies for material characterization\nExperience managing supplier quality programs, including audit planning, corrective action tracking, and process capability studies\nKnowledge of IPC standards relevant to PCB fabrication and testing. Track record of driving PCB technology improvements from R&D through high-volume manufacturing\nNVIDIA is widely considered one of the technology world's most desirable employers. We have some of the most forward-thinking and hardworking people in the world working for us. If you're excited about pushing the boundaries of PCB technology that enables the world's most powerful AI systems, come join us","description_format":"text","description_chars":3845,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Processors, MCUs & AI Chips","Servers & Data Center Hardware","Computer Components","AI Chips & Accelerators"],"lifecycle":[{"event":"open","at":"2026-08-07T00:00:00Z"},{"event":"close","at":"2026-08-08T15:13:29Z"},{"event":"reopen","at":"2026-09-03T08:08:33Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.447,"p_room":0.28,"age_days":74,"expected_fill_days":33,"reasons":["conf:32","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/nvidia-senior-signal-integrity-and-pcb-quality-engineer","json_url":"https://alion.io/job/nvidia-senior-signal-integrity-and-pcb-quality-engineer.json","meta":{"generated_at":"2026-10-20T21:30:38Z","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":25046,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":6},"rest":"https://alion.io/mcp/rest/get_company?id=6"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnvidia-senior-signal-integrity-and-pcb-quality-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%2Fnvidia-senior-signal-integrity-and-pcb-quality-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%2Fnvidia-senior-signal-integrity-and-pcb-quality-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/nvidia-senior-signal-integrity-and-pcb-quality-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnvidia-senior-signal-integrity-and-pcb-quality-engineer"}]}
