Lila Sciences is building Scientific Superintelligence to solve major scientific challenges through advanced AI models and proprietary AI Science Factory instruments. The company is assembling a talent-dense AI safety team to identify and mitigate risks from scientific superintelligence while preserving core scientific discovery capabilities. You will serve as a materials scientist focused on mapping dual-use risks across the materials sciences domain. Your role bridges deep materials expertise with risk assessment to safeguard increasingly capable scientific AI systems. Key responsibilities include: - Map misuse risks by connecting material properties, processing, and functional performance across materials domains to harmful applications, including emerging or overlooked uses of scientific advances - Assess how physical feasibility, processing complexity, manufacturing requirements, and actors' resources affect the plausibility and likelihood of misuse, including which constraints AI could change - Distinguish established capabilities, plausible future developments, and weakly supported hypotheses, revising assessments as evidence changes across models, tools, and automated laboratories - Identify expertise gaps, commission targeted scientific input with the expert-program team, and integrate specialist findings into a coherent risk landscape assessment - Translate dual-use judgments into policy boundaries, evaluation priorities, and mitigation requirements that support beneficial materials research - Collaborate with threat modelers, evaluation researchers, engineering and experimental colleagues to assess capabilities, interpret red-team findings, and evaluate safeguards You will work across science, model training, and lab integration teams to develop and implement a bespoke safety strategy tailored to Lila's specific goals and deployment strategies. The role involves technical safety strategy development, broader ecosystem engagement, safety-focused evaluations, safety systems design, and research into longer-term needs such as oversight of superintelligent scientific systems. REQUIREMENTS: - PhD or comparable experience in materials science or closely related discipline, with strong grasp of relationships between structure, properties, processing, and applications. Relevant backgrounds include particulate, porous and formulated systems; structural and functional materials including thin films, electrochemical materials, metals and alloys - Substantive experience assessing dual-use risks in a relevant area, with strong understanding of harmful applications such as nuclear proliferation, radiological misuse, weapons-related capabilities (e.g., energetics), or other consequential materials risks - Sound judgment about physical possibility, practical feasibility, and uncertainty, with ability to investigate risks beyond immediate specialism - Ability to identify appropriate specialists, evaluate technical evidence, and synthesize contributions across scientific and security disciplines - Clear scientific communication, independent research judgment, and ability to collaborate across science, engineering, and policy BONUS: - Prior experience applying materials or related physical-science expertise to AI safety through threat analysis, evaluations, red teaming, or mitigation design - Experience commissioning specialist research or assessing emerging technologies across disciplinary boundaries - Experience with computational materials science, advanced manufacturing, or automated synthesis and characterization
