Principal Opto-Mechanical Engineer

Job Description

Our client is an engineering organisation specialising in the development of high-performance optical and sensing technologies for demanding environments. The company supports critical applications across aerospace, defence, and industrial sectors, with a strong focus on the integration of optics, electronics, and mechanical systems.

Mission

The Principal Opto-Mechanical Engineer will lead the mechanical design and system integration of advanced optical assemblies, contributing to the development of next-generation sensor and imaging technologies. This senior technical role combines hands-on design leadership with strategic oversight of design for manufacture, system integration, and environmental qualification. Working closely with optical, systems, and production teams, the successful candidate will ensure that all designs meet stringent mechanical and optical specifications while operating reliably under real-world constraints.

Responsibilities

Opto-Mechanical Design & Integration

• Lead the full design lifecycle of complex opto-mechanical systems from initial concept through to production release.
• Develop CAD models and detailed drawings compliant with internal quality standards and production requirements.
• Define mechanical tolerances and constraints in alignment with optical and thermal performance requirements.

Cross-Functional Development

• Collaborate with optical, thermal, systems, and electronics engineers to define interface requirements and achieve optimal system integration.
• Drive prototype builds and validation efforts, supporting hands-on assembly and testing where needed.

Performance & Reliability Assurance

• Support environmental qualification including shock, vibration, humidity, chemical resistance, and temperature extremes.
• Apply DFM, DFA, and DFT principles to ensure robust, scalable, and cost-effective designs.

Technical Documentation & Review

• Prepare technical documentation including specifications, interface control documents, and verification plans.
• Lead design reviews and contribute to the development of internal engineering standards and best practices.
• Provide technical guidance to junior engineers and actively participate in team development and knowledge transfer.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering, Optical Engineering, or a closely related discipline.
• At least 10 years of experience in the design and integration of precision opto-mechanical systems.
• Expertise in optical tolerancing, thermal and structural analysis, and mechanical integration of optical elements.
• Proficiency in 3D CAD tools such as SolidWorks, Creo, or NX.
• Experience in environmental testing and qualification of mechanical assemblies.
• Strong communication and documentation skills in English.

Preferred Experience

• Experience in sectors such as aerospace, defence, or optical instrumentation.
• Familiarity with polymers or lightweight materials used in optical system enclosures.
• Exposure to AI-driven design optimization or multidisciplinary system development.
• Location: Edinburgh, Scotland, United Kingdom
