Software Engineer, Data Visualization

Software Engineer, Data VisualizationLos Angeles, CAAbout the CompanyGeneral Matter enriches uranium. We are designing, building, and operating the world's lowest-cost enrichment services, here in the US. In the process, we are restoring America's ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume. Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way. Our 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. We 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. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production. We are a mission-driven company with a culture of urgency, accountability, and transparency. Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable.About This RoleWe 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.ResponsibilitiesDesign, implement, and maintain high-performance live charting and dashboards for kHz-class, high-channel-count sensor telemetry across test and production environments.Develop and integrate HMI/SCADA interfaces for monitoring, control, alarming, and operational visibility.Build real-time streaming UIs that stay responsive under load, and post-processing tools for cross-run comparison, derived signals, and campaign analysis.Define and champion modern software engineering practices, UI architecture, rendering standards, testing strategies, and operational best practices across the visualization stack.Work closely with data platform, controls, and test automation teams to consume streaming and time-series interfaces directly.Lead debugging, root cause analysis, and performance improvements across the full rendering-to-data stack.Basic QualificationsBachelor's degree or higher in Computer Science, Computer Engineering, Software Engineering, or a related field.5+ years of experience building real-time or data-intensive user interfaces.Strong, production-level experience in TypeScript/React (or equivalent) and Python.Hands-on experience with high-performance rendering and live data visualization, with a strong understanding of streaming data and UI performance under load.Experience with high-reliability, on-premise, 24/7 deployments in safety-critical environments.Preferred Skills and ExperienceExperience with HMI/SCADA platforms (e.g., Ignition) and dashboarding tools (e.g., Grafana).Experience with WebGL, canvas, or custom rendering for high-throughput, many-channel data.Experience with pub/sub and time-series interfaces (e.g., OPC-UA, MQTT).Background in high-performance HMI design for situational awareness and alarm management.Ability to work across the stack, including the data and streaming layers that feed visualization.Background in high-reliability or real-time environments (e.g., industrial automation, aerospace, energy, medical devices, finance/trading, gaming and real-time graphics).Demonstrated technical leadership in setting engineering standards, and building and mentoring high-performance engineering teams.Additional RequirementsAbility to work extended hours and weekends as necessary.Equal Opportunity EmployerGeneral 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.Compensation and BenefitsThe base salary range for this role is $125,000-$200,000 annually.
