From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.\nWe’re a well-funded startup backed by Mayfield and led by industry’s veterans who’ve built and scaled some of the most transformative technologies in the industry. This isn’t incremental innovation, it’s a ground-floor opportunity to rethink the optical layer from the silicon up. You’ll work alongside a team of world-class engineers solving some of the hardest challenges in optics, systems, and scale. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow. \nIf you're looking for mission, momentum, and the chance to make an outsized impact jump on the rocket ship. We’re just getting started.\nPOSITION OVERVIEW\nWe’re looking for a Senior/Staff Software Engineer, Data to build the data pipelines and visualizations that turn raw manufacturing and test data into reliable signal for the engineers running our lines, the researchers pushing the technology forward, and the leadership team steering the company. You’ll work directly with optical, manufacturing, and quality/reliability engineers to design the pipelines, data models, and dashboards that help a fast-growing, multi-site organization make decisions based on trustworthy data.\nWhat You'll Do:\nArchitect and build the data pipelines and infrastructure that turn manufacturing and test data, including yield, SPC, failure, and reliability data, into dependable signal for engineering and leadership decisions.\n\nDesign, build, and maintain dashboards and visualizations for stakeholders across the executive team, internal engineering, and external customers.\n\nPartner directly with optical, manufacturing, and quality/reliability engineers to translate ambiguous domain requirements into robust data models and tooling.\n\nBuild and maintain automated data quality checks and validation pipelines, including checks that gate critical processes such as shipping readiness.\n\nIdentify and close data gaps, including missing, inaccurate, or inconsistent data, in close collaboration with domain experts and other data/ML engineers.\n\nDrive improvements to pipeline reliability, turnaround time, and cost across product lines.\n\nApply strong software engineering practices, including version control, testing, code review, and CI/CD, to data systems, not just analysis scripts.\n\nHelp set technical direction for the data organization as it scales across sites in Thailand, Bangalore, Singapore, and the United States, and mentor other engineers on the team.\n\nKey Qualifications:\n5+ years of professional software engineering experience, with a substantial portion spent building and owning data systems such as data engineering, analytics engineering, or backend systems handling large operational datasets. We are hiring across Senior and Staff levels.\n\nStrong SQL skills and experience designing, building, and maintaining data pipelines.\n\nHands-on experience building dashboards and visualizations with a BI or analytics framework such as Superset, Looker, Tableau, or similar. Direct experience with Apache Superset is a strong plus.\n\nProficiency with the Python data stack, including pandas and numpy, and visualization libraries such as matplotlib, seaborn, altair, or similar.\n\nExperience with cloud data infrastructure, preferably AWS.\n\nTrack record of partnering directly with non-data domain experts to turn ambiguous requirements into concrete, reliable data solutions.\n\nComfort owning a system end-to-end, from data model through dashboard, in a fast-moving startup environment.\n\nPreferred Skills:\nExperience with manufacturing, semiconductor, hardware, or other high-volume operational or test data.\n\nFamiliarity with statistical process control, SPC, or yield analysis concepts.\n\nExperience working across distributed, multi-site teams.\n\nWhy Join Us?\nCompetitive salary commensurate with experience\nComprehensive benefits package including health insurance\nProfessional development opportunities and certification support\nAccess to cutting-edge technology and cloud platforms\nCollaborative work environment with cross-functional teams\nInnovate with a Silicon Valley headquartered team, change the world\nLumilens is an equal opportunity employer.
