Job Title: Principal Optical Engineer

Job Description

We are seeking a Principal Optical Engineer to lead the design, integration, and validation of electro-optical and infrared (EO/IR) systems across the full product lifecycle, from early lab prototyping through fielded deployment. This role blends hands-on laboratory work, optical design, and system integration, supporting rapid development efforts for next-generation sensing and imaging systems.

Responsibilities

• Serve as a technical lead for optical systems, supporting development from concept through prototype, integration, and transition to production.
• Perform Detection, Recognition, Identification (DRI) analysis to evaluate EO/IR system performance in operational environments.
• Collaborate with cross-functional teams (mechanical, electrical, software, systems) to integrate sensors and optical subsystems into larger platforms.
• Build, align, and test benchtop optical prototypes, validating performance against requirements.
• Operate and expand a laboratory environment for optical testing and characterization, including use of integrating spheres, collimators, and alignment stations.
• Conduct sensor characterization across multiple spectral bands, including visible, near IR (NIR), shortwave IR (SWIR), midwave IR (MWIR), and longwave IR (LWIR).
• Perform precision alignment of optical systems using laser-based techniques.
• Define system-level requirements and select optical components such as lenses, sensors, lasers, stabilization systems, and displays.
• Develop and optimize optical designs using Zemax, including tolerance analysis and performance modeling.
• Support stray light analysis and recommend mitigation strategies.
• Verify and test optical hardware delivered from vendors to ensure compliance with specifications.
• Generate technical documentation and clearly communicate results to internal stakeholders and external partners.

Essential Skills

• Bachelor’s degree in optical engineering or related field.
• 15+ years of experience in the optical design field.
• Experience in laboratory environments, including expertise with opto-mechanical assembly, alignment tools, optical bore sighting, and laboratory testing.
• Design experience incorporating HD visible sensors, SWIR, MWIR, and LWIR sensors with optical assemblies.
• Experience modeling sensor systems to predict system performance for detection, recognition, and identification of objects.
• Knowledge of techniques and specifications for Optical Image Stabilization (OIS) and Fast Steering Mirrors (FSM).
• Experience specifying displays, especially near-eye displays for systems such as sights, binoculars, and AR/VR systems.
• Experience designing and modeling lenses and other optical components in Zemax.
• A solid knowledge of relevant optical component suppliers.
• Willingness to travel up to 10% to support project needs.
• Must have active Secret or higher level clearance.

Additional Skills & Qualifications

• Experience modeling sensor systems in the Night Vision Integrated Performance Model.
• Experience mentoring junior optical engineers.
• Experience with hyperspectral systems.
• Technical writing and presentation skills.
• Experience with laser designators, laser range finders, laser dazzlers, and other tactical laser systems.

Work Environment

The role is primarily located at the Lorton, VA facility with 25% or more travel to Fort locations for customer engagements. The work environment involves hands-on lab work and system-level ownership, providing exposure to cutting-edge EO/IR and sensing technologies and the opportunity to influence programs from early concept to fielded capability.

This is a Permanent position based out of Lorton, VA.

The pay range for this position is $180000.00 - $200000.00/yr.
