We work at the intersection of machine learning, hardware, and software, creating technologies that reshape how people communicate and experience the world around them in everyday life.\nDescription\nWe are a growing physics and advanced technology team working at the intersection of cutting-edge research and real-world product feasibility. We are seeking a senior Physicist with deep domain expertise in laser-tissue interaction and laser safety engineering. In this role, you will lead the scientific investigation of optical energy delivery, investigate photo-induced tissue damage mechanisms, and establish the fundamental safety and formal classification frameworks for a groundbreaking, first-of-its-kind optical technology.\nDefine experimental and theoretical research strategies to characterize light-tissue interactions, optical penetration, and thermal/mechanical effects in biological media.\nDesign, build, and operate experimental lab setups to investigate photo-induced tissue damage (e.g., dermal and ocular tissue models), defining precise biological damage thresholds and exposure margins.\nServe as the team's foremost authority on laser safety, leading formal laser classification (e.g., IEC 60825, ANSI Z136, FDA CDRH) and product safety compliance.\nTranslate complex biological damage models and physical limits into actionable system-level specifications, hardware constraints, and operational safeguards.\nDefine and design system level solutions for safety compliance.\nDevelop and validate analytical and numerical simulation models (e.g., Monte Carlo light transport, thermal bio-heat equations) to predict tissue response and optical safety margins.\nAnalyze and report empirical findings clearly, enabling cross-functional engineering teams to make rigorous, risk-informed architecture decisions.\nPartner with multidisciplinary teams across hardware, firmware, optics, and human factors to drive feasibility from concept to safe, viable product implementations.\nMinimum Qualifications\nPh.D in Physics, Biomedical Engineering, Electrical Engineering, or a closely related discipline.\n10+ years of hands-on experience in laser physics, biomedical optics, or laser-matter interaction.\nProven track record in experimental research investigating light-tissue interaction and photo-induced tissue damage (thermal, photochemical, or photomechanical mechanisms).\nDirect laboratory experience working with lasers and biological tissues (tissue optics, ex-vivo/in-vitro models, or tissue phantoms).\nIn-depth expertise in laser safety standards and formal classification\nStrong hands-on laboratory capabilities: setting up optical beam delivery, beam profiling, dosimetry, and sensitive detection/characterization instrumentation.\nPreferred Qualifications\nPost-doctoral research or leadership role in biophotonics, laser-tissue dynamics, or medical laser technology.\nHands-on experience navigating regulatory approval or safety certification for consumer or medical optical systems.\nDeep understanding of ultrafast / short-pulse laser interactions with biological tissue and nonlinear optical damage regimes.\nProficiency with numerical modeling of optical propagation in scattering media (e.g., Monte Carlo simulations of light transport, FEM bio-heat transfer).\nOutstanding communicator with the ability to bridge fundamental biophysics, laser safety standards, and practical hardware design for cross-functional teams.","description_format":"text","description_chars":3527,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating
