The LVIS software, NeuroMatch®, utilizes\nbrainwave signals from traditional EEG systems to enable AI driven algorithms to perform EEG\nsource localization, spike and seizure event detection. We have an international team with our\nheadquarters located in Palo Alto, California, USA and we have an office in Gangnam, Seoul,\nSouth Korea. We are looking for talented individuals to join us in transforming the neurology\nhealth care industry.\nAbout the Role\nNeuroMatch renders large volumes of EEG and neurological data through interactive 2D and 3D\nvisualizations in the browser. This includes a custom, low level WebGL2 rendering engine for\nreal time signal and waveform visualization, with GPU accelerated signal processing (GPGPU),\nplus a Three.js based 3D brain visualization layer, both built on top of our Vue frontend.\nWe're looking for a senior WebGL / graphics engineer to take ownership of this visualization\ntechnology: extending the custom rendering engine, maintaining the 3D brain visualization layer,\nand solving the GPU performance and large dataset problems that come with continuously\nstreamed clinical data.\nYou'll work closely with frontend engineers, neuroscientists, and clinical specialists to translate\nscientific algorithms and reference implementations into fast, precise, production visualization Software.\nRequirements\nOwn and extend our custom WebGL2 rendering engine used for real time EEG\nwaveform and signal visualization.\nMaintain and build out our Three.js based 3D brain visualization components (source\nlocalization, spike and seizure networks, and related views).\nDesign and implement GPU accelerated (GPGPU) signal processing techniques for in\nbrowser filtering and data preparation.\nOptimize GPU and CPU performance, memory use, and rendering throughput for large,\ncontinuously streamed datasets.\nWrite and optimize GLSL shaders for custom rendering and data processing pipelines.\nIntegrate visualization components into our Vue based frontend application.\nCollaborate with neuroscientists and clinical specialists to implement algorithms and\nreference implementations as production software.\nProfile and resolve rendering performance issues, memory issues, visual artifacts, and\nbrowser/GPU compatibility problems.\nContribute to frontend architecture, code quality, and technical design reviews.\nBasic Qualifications\n5+ years of professional software development experience, with substantial hands on\nWebGL 2.0 / GLSL development (not just framework usage).\nStrong JavaScript (ES6) / TypeScript skills.\nDirect experience writing and debugging GLSL shaders, and working with GPU buffers,\ntextures, and render pipelines.\nExperience building and maintaining complex, interactive, browser based applications\nhandling large or streaming datasets.\nBS or higher degree in Computer Science, Electrical Engineering, or a related technical\nfield, or equivalent practical experience.\nPreferred Qualifications\nExperience with Three.js and Vue.js.\nHands on experience with digital signal processing, such as digital filter design or noise\nreduction.\nFamiliarity with GPGPU techniques using WebGL, and with floating point standards such\nas IEEE 754.\nFamiliarity with OpenGL, Vulkan, Direct3D, Metal, SPIR-V, HLSL, OpenCL, or CUDA.\nExperience with WebAssembly, Web Workers, SharedArrayBuffer, or SIMD based\nbrowser performance techniques.\nExperience with large scale data visualization (medical, scientific, geospatial, or\nfinancial).\nExperience with Emscripten or C/C++ to WebAssembly workflows.\nExperience with automated testing, CI/CD, and git based code review practices.\nExperience with EEG, neuroscience, or medical software is helpful but not required; our\nscience and clinical teams provide the domain knowledge needed.\nPreferred Qualifications\nRendering large EEG waveform datasets smoothly and in real time in the browser.\nVisualizing neurological activity on interactive 3D brain models.\nBuilding GPU accelerated signal processing and visualization pipelines.\nImproving rendering performance and reducing memory use for long duration EEG\nrecordings.\nBuilding visualization tools that let physicians and researchers explore complex\nneurological data interactively.\nOther Information\nJob type: Full-time, On-Site\nLocation : Palo Alto, CA\nBenefits\nBenefits: Comprehensive Health, Dental, and Vision coverage.\nCompensation\n Base Salary: $135,000 to $175,000 annually \nActual compensation may vary based on experience, skills, qualifications, and location.","description_format":"text","description_chars":4725,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Neurotech & Neuromodulation"],"lifecycle":[{"event":"open","at":"2026-10-26T21:22:26Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"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":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":36,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-28T05:59:10Z"},"pay":{"stated_usd_annual":175000,"is_top_pay":true},"html_url":"https://alion.io/job/lvis-corporation-frontend-webgl-graphics-engineer","json_url":"https://alion.io/job/lvis-corporation-frontend-webgl-graphics-engineer.json","meta":{"generated_at":"2026-10-29T00:35:27Z","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":753,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":679125},"rest":"https://alion.io/mcp/rest/get_company?id=679125"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flvis-corporation-frontend-webgl-graphics-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%2Flvis-corporation-frontend-webgl-graphics-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%2Flvis-corporation-frontend-webgl-graphics-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/lvis-corporation-frontend-webgl-graphics-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flvis-corporation-frontend-webgl-graphics-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3294643}},{"tool":"search_jobs","arguments":{"company":"lviscorp.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3294643},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
