Our team works 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.

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.

Responsibilities

Define experimental and theoretical research strategies to characterize light-tissue interactions, optical penetration, and thermal/mechanical effects in biological media
Design, 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
Serve 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
Translate complex biological damage models and physical limits into actionable system-level specifications, hardware constraints, and operational safeguards
Define and design system level solutions for safety compliance
Develop 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
Analyze and report empirical findings clearly, enabling cross-functional engineering teams to make rigorous, risk-informed architecture decisions
Partner with multidisciplinary teams across hardware, firmware, optics, and human factors to drive feasibility from concept to safe, viable product implementations
Lead the biological and physical risk assessment for novel optical concepts, pinpointing exposure limits, hazards, and mitigation pathways
Conduct hands-on lab experiments combining lasers and biological tissue models to measure, observe, and quantify damage mechanisms under varied irradiation profiles
Formulate and own the formal laser product classification strategy, defining engineering controls, interlocks, and compliance documentation
Characterize system-level physical limits and optical delivery parameters (wavelength, pulse duration, fluence, beam profile) to maximize performance while strictly adhering to safety standards
Author comprehensive safety reports, compliance dossiers, and technical whitepapers to support engineering choices and regulatory alignment

Requirements

Ph.D in Physics, Biomedical Engineering, Electrical Engineering, or a closely related discipline
10+ years of hands-on experience in laser physics, biomedical optics, or laser-matter interaction
Proven track record in experimental research investigating light-tissue interaction and photo-induced tissue damage (thermal, photochemical, or photomechanical mechanisms)
Direct laboratory experience working with lasers and biological tissues (tissue optics, ex-vivo/in-vitro models, or tissue phantoms)
In-depth expertise in laser safety standards and formal classification
Strong hands-on laboratory capabilities: setting up optical beam delivery, beam profiling, dosimetry, and sensitive detection/characterization instrumentation
Outstanding communicator with the ability to bridge fundamental biophysics, laser safety standards, and practical hardware design for cross-functional teams

Nice to have

Post-doctoral research or leadership role in biophotonics, laser-tissue dynamics, or medical laser technology
Hands-on experience navigating regulatory approval or safety certification for consumer or medical optical systems
Deep understanding of ultrafast / short-pulse laser interactions with biological tissue and nonlinear optical damage regimes
Proficiency with numerical modeling of optical propagation in scattering media (e.g., Monte Carlo simulations of light transport, FEM bio-heat transfer)
