Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.\nOur mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society. \nWe were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms. \nOur lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production. \nWe are a mission-driven company with a culture of urgency, accountability, and transparency. \nHelp us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. \nAbout This Role\nWe are seeking a Data Visualization Software Engineer to design and implement the visualization and operator-facing interfaces for test stands and production systems. This role sits at the intersection of real-time frontend engineering and industrial data systems, and is responsible for building high-performance, reliable UIs that render high-throughput, high-channel-count sensor telemetry live and support situational awareness, alarm management, and post-run analysis. The successful candidate will play a central role in defining the architecture, rendering standards, and UX of mission-critical visualization systems across R&D, manufacturing/test, and plant operations. \nResponsibilities\nDesign, implement, and maintain high-performance live charting and dashboards for kHz-class, high-channel-count sensor telemetry across test and production environments. \nDevelop and integrate HMI/SCADA interfaces for monitoring, control, alarming, and operational visibility. \nBuild real-time streaming UIs that stay responsive under load, and post-processing tools for cross-run comparison, derived signals, and campaign analysis. \nDefine and champion modern software engineering practices, UI architecture, rendering standards, testing strategies, and operational best practices across the visualization stack. \nWork closely with data platform, controls, and test automation teams to consume streaming and time-series interfaces directly. \nLead debugging, root cause analysis, and performance improvements across the full rendering-to-data stack. \nBasic Qualifications\nBachelor’s degree or higher in Computer Science, Computer Engineering, Software Engineering, or a related field. \n5+ years of experience building real-time or data-intensive user interfaces. \nStrong, production-level experience in TypeScript/React (or equivalent) and Python. \nHands-on experience with high-performance rendering and live data visualization, with a strong understanding of streaming data and UI performance under load. \nExperience with high-reliability, on-premise, 24/7 deployments in safety-critical environments. \nPreferred Skills and Experience\nExperience with HMI/SCADA platforms (e.g., Ignition) and dashboarding tools (e.g., Grafana). \nExperience with WebGL, canvas, or custom rendering for high-throughput, many-channel data. \nExperience with pub/sub and time-series interfaces (e.g., OPC-UA, MQTT). \nBackground in high-performance HMI design for situational awareness and alarm management. \nAbility to work across the stack, including the data and streaming layers that feed visualization. \nBackground in high-reliability or real-time environments (e.g., industrial automation, aerospace, energy, medical devices, finance/trading, gaming and real-time graphics). \nDemonstrated technical leadership in setting engineering standards, and building and mentoring high-performance engineering teams. \nAdditional Requirements\nAbility to work extended hours and weekends as necessary.\nAbility to come into our office every day. This role is 100% on site and in person.\nCurrently a US Citizen with capability to obtain and maintain a US Q clearance.\nEqual Opportunity Employer\nGeneral Matter is an Equal Opportunity Employer; employment with General Matter is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.\nCompensation and Benefits\nThe base salary range for this role is $125,000-$200,000 annually. \nCompensation bands are determined by role, level, location, and alignment with market data. Individual level and base pay is determined on a case-by-case basis and may vary based on job-related skills, education, experience, technical capabilities and internal equity. Please note that the stated salary range is an estimate and may be adjusted based on market conditions, business needs, or other factors.In addition to base salary, for full-time hires, you may also be eligible for long-term incentives, in the form of stock options, and access to medical, vision & dental coverage as well as access to a 401(k) retirement plan.","description_format":"text","description_chars":5574,"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":true,"languages":[]},"benefits":["Equity","Retirement plans","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Nuclear Energy","Nuclear Engineering"],"lifecycle":[{"event":"open","at":"2026-09-06T07:14:47Z"}],"visa":[],"liveness":{"score":25,"band":"fade","label":"Fading","p_open":1,"p_active":0.579,"p_room":0.44,"age_days":51,"expected_fill_days":47,"reasons":["conf:1","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/general-matter-software-engineer-data-visualization","json_url":"https://alion.io/job/general-matter-software-engineer-data-visualization.json","meta":{"generated_at":"2026-10-24T05:37:05Z","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":7969,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":171806},"rest":"https://alion.io/mcp/rest/get_company?id=171806"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgeneral-matter-software-engineer-data-visualization"},{"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%2Fgeneral-matter-software-engineer-data-visualization"},{"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%2Fgeneral-matter-software-engineer-data-visualization"},{"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/general-matter-software-engineer-data-visualization\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgeneral-matter-software-engineer-data-visualization"}]}
