About the role

You’ll be collaborating closely with design engineering, supply chain, and quality teams to develop scalable build processes for high precision opto mechanical systems.

A typical day for an Optics Manufacturing Engineer could look like this: Manufacturing Process Development

• Developing and implementing robust manufacturing processes for complex optomechanical assemblies used in AFM systems
• Translating prototype builds into scalable, reliable production workflows while protecting precision and repeatability
• Designing assembly procedures, tooling, fixtures and clear work instructions that support the team
• Establishing process capability and building manufacturing readiness for new product introductions

Opto Mechanical Assembly & Alignment

• Leading the development of precise assembly and alignment processes for optical and mechanical subsystems
• Defining supportive best practices for handling and integrating sensitive optical components, sensors and precision stages
• Creating intuitive procedures for optical alignment, calibration and verification within production environments

New Product Introduction (NPI)

• Partnering closely with Engineering to guide smooth design transfer into production
• Providing thoughtful, practical Design for Manufacturing feedback throughout development
• Supporting pilot builds, validation builds and early production ramps with a calm, collaborative approach
• Identifying and resolving manufacturing challenges early and constructively

Production Scaling

• Collaborating with Quality to lift throughput, yield and overall consistency
• Spotting opportunities for gentle automation, modularisation and better assembly flow
• Supporting production ramp planning as manufacturing capacity grows Tooling, Fixtures & Test Systems
  • Designing and implementing precision tooling and fixtures that enable repeatable, confident optomechanical assembly
  • Developing supportive test and calibration setups to validate system performance during production
  • Working closely with Engineering, NPI, Quality, Supply Chain and Customer Support to keep everyone aligned
  • Supporting supplier development for precision components and optical assemblies
  • Contributing to root cause investigations for manufacturing or field performance issues
  • Offering technical support and encouragement to production technicians and wider manufacturing teams

  Who we are looking for

  • Working in low volume, highly complex opto mechanical equipment manufacturing scale up environments
  • Expert knowledge of optics & optical systems; including lasers & optical fibre
  • Familiarity with systems involving vibration isolation and precision motion control
  • Working in a fast paced environment where good judgement needs to be exercised
  • Familiarity with manufacturing techniques for tight tolerance systems
  • Extensive knowledge of DFM, operational excellence and process capability methods
  • Ownership mindset – promotes accountability for outcomes
  • Leadership mindset – solves for business need, not just departmental
  • Hands on problem solver who thrives in highly technical environments

  Nice to have

  • Experience in semiconductor equipment and/or laser manufacturing
  • Proficiency with CAD tools and engineering documentation

  Education / Qualifications

  • Either a degree in Physics or Engineering or similar, or a clear equivalent path through relevant apprenticeship or accumulated experience.
  • Over 5 years’ experience in a relevant industry

  We look for these attributes for our team

  • Self management: Able to work independently, setting priorities for own work based upon the company goals and targets.
  • Teamwork: Engages with other members of the company to bring the best solutions to the problem. Recognises the value that fellow company members bring to enhance own abilities. Supports colleagues with their tasks when critical to the company goals.
  • Impact and Influence: Establishes itself as the knowledge centre in its own field.
  • Ownership & Initiative: Reacts and addresses both short and medium term issues and proactively takes action to solve them.
  • Results Orientation: Focuses on the company goal, avoids distraction, making timely decisions to achieve the target.
