Job description

Description

The Leidos Defense Space Business Area is seeking a talented Optical Materials Scientist to support our Emerging Space Systems Division. In this role, you will drive the development of tunable optical metasurfaces designed to enable multi- and hyper-spectral sensing on next-generation space missions.

Our Space Business Area is actively transforming space payload solutions through customer-funded programs and high-impact internal research and development (IR&D) efforts. If you are passionate about enabling groundbreaking capabilities in space-based sensing and working at the intersection of optical simulation, nanofabrication, and laboratory experimentation, we want you on our team.

Key Responsibilities

• Design & Modeling: Lead full-wave electromagnetic modeling to identify, optimize, and evaluate tunable infrared metasurface filters based on phase change materials.
• Performance Simulation: Architect advanced models to analyze the specific impact of tunable filters on the overall performance of infrared sensor systems.
• Fabrication Planning: Research, identify, and establish viable methods to successfully fabricate optimized optical designs.
• Experimental Validation: Create and execute comprehensive laboratory characterization plans to validate modeled performance against real-world data.
• Cross-Functional Collaboration: Partner closely with senior engineers and multidisciplinary teams to evaluate, test, and mature emerging optical technologies.
• Data Analysis & Documentation: Analyze experimental data to inform ongoing design decisions and document technical results to support IR&D and formal program milestones.

Basic Qualifications

• Education: BS degree in Physics, Materials Science, Optics, or a related field with 8+ years of prior relevant experience or MS degree with 6+ years of prior relevant. May possess a Doctorate in technical domain.
• Security Clearance: US citizenship with the ability to obtain and maintain an active DoD Secret security clearance.
• Core Experience: Demonstrated research or development experience specifically in optical and infrared materials.
• Software Proficiency: Hands-on experience with full-wave electromagnetic modeling software (e.g., Ansys HFSS, COMSOL, or Lumerical).
• Technical Knowledge: Deep familiarity with the infrared/optical properties of materials (including phase change materials), metamaterials, and metasurfaces.
• Sensor Technology: Foundational familiarity or experience with infrared detector technology.
• Optimization Skills: Experience utilizing optimization methods, including adjoint gradient descent and topology optimization.
• Professional Skills: Strong analytical problem-solving skills, sharp attention to detail, and effective written/verbal communication skills.

Preferred Qualifications

• Active Clearance: Active Secret clearance with the ability to obtain a higher-level clearance (TS/SCI).
• Cleanroom Experience: Hands-on experience with cleanroom environments and nanofabrication techniques (e.g., electron-beam lithography, photolithography, etching).
• Spaceflight Hardware: Prior exposure to designing optical components intended for space environments or satellite payloads.
• Programming: Proficiency in Python, MATLAB, or C++ for automated data collection or custom optical modeling scripts.
• Publication Record: Record of research contributions demonstrated through peer-reviewed publications, patents, conference presentations, or development of relevant optical technologies.
