1d•$168,200 - $252,200•Onsite

About The Position

Northrop Grumman Space Systems is looking for a Staff Optical Engineer to support the Electro‑Optics Group within the Launch Vehicles business unit in Chandler, Arizona. You will work as part of a multi‑disciplinary seeker engineering team responsible for optical design, analysis, integration, and test of development and flight hardware. The role is centered on optical engineering for imaging and sensing systems (visible through LWIR), with an emphasis on how opto‑mechanical design and environments drive optical performance. At the staff level, you will provide technical leadership, develop and implement new tools and methods, and ensure system‑level performance across the full mission profile.

Requirements

Bachelor’s degree in Optical Engineering, Physics, Mechanical Engineering, Electrical Engineering, or related discipline from an accredited university and 12 years of relevant experience; or a Master’s degree and 10 years of experience; or a PhD and 8 years of experience.
Active U.S. Government Department of Defense (DoD) Secret security clearance at time of application.
Demonstrated experience with optical systems used in imaging, sensing, or seeker applications; including system-level performance ownership.
Experience with optical performance analysis and an understanding of how structural and thermal environments affect imaging quality and line of sight (e.g., STOP/SILOS concepts).
Proficiency with optical modeling tools (e.g., ZEMAX, Code V, FRED, or equivalent) for design, analysis, and tolerancing.
Experience with 3D CAD tools (e.g., CREO, NX, SolidWorks) to interface effectively with opto‑mechanical designs; ANSYS Mechanical experience preferred.
Experience with optical imaging systems in one or more spectral bands (e.g., visible, NIR, SWIR, MWIR, LWIR).
Demonstrated ability to independently determine and develop technical approaches and solutions, complete complex tasks with minimal oversight, and drive tasks to completion.
Strong technical communication skills, including the ability to generate clear documentation and present optical design/analysis results to technical and non‑technical audiences, and to represent the organization in technical discussions with customers.

Nice To Haves

MS or PhD in Optical Engineering, Physics, or Mechanical Engineering with a focus on optical systems.
Previous experience with DoD missile defense or seeker programs, including familiarity with performance verification frameworks, environmental qualification, and flight test correlation.
Hands‑on experience with STOP and SILOS modeling workflows and integration of structural/thermal results with optical design tools.
Experience with DoD missile defense programs and associated standards pertaining to missile systems, seeker systems, or other high‑reliability environmentally challenging electro‑optical applications.
Deep experience with EO systems, including optical design, analysis and tolerancing, stray light control, error budgets, radiometric budgets, opto-mechanical design, and focal plane technologies.
Demonstrated experience leading optical and environmental test campaigns and correlating measured optical performance to predictive analyses.
Experience serving as a subject matter expert and/or technical lead across functional teams, including mentoring, technical review, and cross discipline coordination.

Responsibilities

Lead and contribute to the design and analysis of optical systems for imaging and sensing applications (e.g., refractive/reflective optics, relay optics, athermalized systems, objective lenses).
Perform and own optical performance analyses (e.g., wavefront error, MTF, line of sight (LOS) stability, boresight, sensitivity, and tolerancing) across expected environmental and operational conditions, with a high degree of self-checking.
Develop and maintain optical error budgets, including contributions from alignment, manufacturing tolerances, thermal and structural effects, and line of sight stability; review others’ work for accuracy and consistency.
Perform and guide Structurally Induced Line of Sight (SILOS) analysis in collaboration with structural and thermal analysts to ensure optical performance is maintained through the full mission profile; drive system level solutions to optical structural thermal interactions.
Define and allocate optical requirements and tolerances at the system, subsystem, and component levels; flow requirements to optomechanical design, manufacturing, and test, ensuring system level compliance.
Collaborate closely with opto-mechanical, systems, electrical, and manufacturing engineers to ensure that optical designs are realizable, producible, and testable, and support system level trade studies and design optimization.
Guide and review the development of optomechanical designs (mounts, cells, structures) that support optical alignment, stability, and environmental robustness; develop or refine methods and tools to improve robustness and efficiency.
Support and sometimes lead laboratory and environmental test activities, including optical alignment, calibration, performance verification, and correlation of analysis to test (vibration, thermal, shock, etc.).
Participate in and frequently lead design reviews (internal and customer), presenting optical design concepts, analyses, error budgets, and test results to stakeholders; serve as a subject matter expert for optical performance.
Provide technical leadership, mentoring, and guidance to early and mid-career engineers in optical design, analysis, and problem solving.
Drive continuous improvement and innovation, including development and implementation of new tools, methods, and processes to improve optical design quality, efficiency, and robustness.
Assist with and often lead troubleshooting, root cause analysis, and design updates for prototype and production hardware when optical performance issues are identified, including system level investigations.
