Job Description
Position Overview
We are seeking an Optical Design Engineer with strong expertise in optical system design, simulation, tolerancing, and validation. The role involves complete ownership of design activities from requirement capture to system validation and customer engagement.
Key Responsibilities
- Project Initiation & Requirements
- Understand system and product requirements; extract relevant inputs.
- Define detailed optical specifications with primary engineering calculations.
- Communicate assumptions, deliverables, timelines, and associated risks.
- Anticipate challenges and provide effective risk mitigation strategies.
- Optical System Design
- Select suitable starting design configurations.
- Perform detailed optical design using Zemax or equivalent tools.
- Conduct optimization, tolerance analysis, and manufacturing sensitivity studies.
- Generate optical drawings, documentation, and design reports.
- Typical systems include:
- EO/IR cameras, night vision optics
- Spectrometers, laser systems
- IR lenses, telescopes, lens stacks
- Present design solutions to customers and internal stakeholders.
- Opto-Mechanical & Cross-Functional Collaboration
- Transfer optical design intent to mechanical teams.
- Support development of mounts, mechanisms, baffles & housings.
- Understand tolerances and environmental impacts on system performance.
- Basic exposure to detectors (CCD, CMOS, IR), acquisition electronics, and system integration.
- Validation & Testing
- Coordinate lens procurement, vendor interactions, and corrective actions.
- Support fabrication, material selection, alignment, and test activities.
- Perform optical validation under laboratory and environmental conditions.
- General Engineering Contributions
- Participate in project initiation, feasibility studies, and cost analysis.
- Provide technical inputs for proposals and solution justification.
- Communication & Soft Skills
- Communicate effectively with customers and cross-functional teams.
- Prepare technical presentations and demonstrate solutions to clients.
- Willingness to travel for trials, studies, and customer discussions.
- Self-driven, quick learner with strong ownership and enthusiasm for optics.
Requirements
- MSc Physics (preferably Semiconductors) / M.Tech (Applied Optics) / MSc Tech (Optics/Photonics)
- 3 – 5 years of hands-on experience with Zemax or equivalent optical design tools
- Strong experience in optical systems design: EO/IR optics, lens stacks, assemblies/sub-assemblies
- Basic knowledge on 3D modelling (modules, components, and full devices)
- Ability to generate ISO-compliant optical design drawings
- Working knowledge of optical manufacturing & design documentation
- Experience in Opto-mechanical design and opto-electronics is an advantage
- Willingness to travel across India and SEA for trials, demonstrations, and customer support
