Optomechanical Engineer - All Levels

The Role

Our optics have to be mounted to sub-micron precision and stay aligned under thermal swings, vibration, and handling. We are seeking optomechanical engineers to design the assemblies the beam path rides on and the alignment schemes that keep them true from bench to field. Your work may look like partnering with Optical Design on tolerancing and alignment budgets and with Thermal on the structural-thermal-optical behavior that drives alignment stability.

Responsibilities

• Design optomechanical assemblies for EON's laser communications terminals, and carry them from concept through first light

• Design mounts, flexures, and kinematic schemes that hold sub-micron alignment under real loads

• Contribute to the line-of-sight error budget: structural dynamics, tolerance stack-up, jitter analysis, and pointing calibration

• Analyze mechanical and thermal stability of the optical train, supporting structural-thermal-optical (STOP) analysis in partnership with Thermal

• Drive tolerance and alignment-budget trades with Optical Design, where optical and mechanical performance are tightly coupled

• Execute alignment verification and metrology, confirming assemblies meet their budgets on the bench and after environmental exposure

• Support environmental test and qualification (vibration, shock, thermal-vac) that proves assemblies hold alignment through launch and field conditions

Basic Qualifications

• A degree in mechanical engineering, optical engineering, physics, or a related discipline

• Optomechanical design experience, including mounts, flexures, or kinematic design

• Hands-on alignment and integration of precision optical assemblies

• Proficiency in 3D CAD (NX, SolidWorks, Creo, or equivalent)

• Comfort moving fast and making sound calls without complete data

Preferred Experience

• Space or airborne optomechanical hardware, including launch-load and on-orbit stability design

• Lasercom or optical communications terminal experience

• Structural FEA (ANSYS Mechanical or equivalent) and structural-thermal-optical reasoning

• Athermalization and materials selection for stability: CTE matching, low-expansion materials (Invar, Zerodur, silicon carbide), and bonded versus mechanical mounting trades

• Fiber-coupling optomechanics: fiber-to-collimator alignment, fiber positioners, or coupling-stability design

• Alignment-verification and metrology methods for precision optical hardware

• Environmental test and qualification (vibration, shock, thermal-vac) for precision hardware

• Cleanliness and contamination control for optical assemblies, including handling, bake-out, and outgassing requirements

A note on level and background: We hire this role at all levels, from Associate through Senior and Principal Optomechanical Engineer, and calibrate title, scope, and compensation to your experience. If this list doesn't perfectly match your background still reach out. We are always looking for exceptional people from many disciplines.

What this job is really like

EON is a lean company by design. There is no program office, no requirements team handing you specs, and no army of analysts. You will build the models, make the calls on incomplete data, and be forced to defend and revise them. You will spend meaningful hands-on time in the lab, not just in reviews. If you do your best work inside a large, well-resourced program, this isn't it. If you want your fingerprints on a Tbps-class link from the start, this is it.

• EON believes the business should be primarily employee owned. In turn, all compensation offers include company stock options for FTEs.

• Relocation assistance to Los Angeles available.

• A real equipment and lab budget.

Location: Culver City, CA (onsite).
