Optomechanical Industrialization Engineer @InSpek

Who Are We
InSpek develops optical microchip sensors capable of measuring multiple molecules, temperature, acidity, oxygenation, and more — directly at the heart of biochemical reactions. Our technology enables smarter production of medicines, food, and energy while minimizing waste. We are a VC-backed, ambitious team pushing the boundaries of what sensors can achieve.

If you thrive in a dynamic, innovative environment and want to shape the future of sensing technology, InSpek is the place for you

What Will You Be Doing
We are seeking an
Optomechanical Industrialization Engineer
to drive the industrialisation of InSpek's sensing systems. You will work on the design, prototyping, and manufacturing of optical and mechanical assemblies involving our chip-scale sensors, OEM components, and custom-made parts. Your work will ensure the mechanical and manufacturing readiness of components, from R&D tools to production-grade assemblies. Your role will be hands-on and collaborative, working closely with internal teams and external partners to debug, prototype, and manufacture next-generation sensing solutions.

Responsabilities
Mechanical & optical design:

• Design and iterate mechanical components and optomechanical assemblies using CAD tools.
• Identify and resolve technical issues in optomechanical assemblies, from component-level challenges to system integration.
• Conduct tests to validate performance, durability, and manufacturability.
• Optimize designs for cost, scalability, and ease of assembly.

Contract Manufacturing & Supplier Coordination

• Identify, qualify, and onboard subcontractors and engineering houses for specialized tasks.
• Act as the primary technical liaison with CMOs, contractors, and industrialization partners.
• Define and communicate technical requirements, review proposals, and answer technical queries.
• Manage procurement, timelines, and technical documentation.
• Ensure smooth transitions from prototyping to volume production.

Quality Control

• Develop and implement quality control protocols for optical, chemical, and mechanical aspects of our sensors.
• Perform incoming inspections and validate components/assemblies against specifications.

COMPETENCIES / PROFIL
You are a hands-on engineer with experience in optical components, mechanical design, manufacturing processes, and quality control. You can manage suppliers, solve technical challenges quickly, and contribute to robust sensor development.

• MSc + 4 years of experience (or equivalent) in optomechanical engineering or industrial design, industrialization
• Strong background in mechanical design (CAD, prototyping, testing), including proficiency with CAD tools and mechanical prototyping (e.g. 3D printing)
• Hands-on experience with optical systems (fibre optics, alignment, assembly)
• Experience with quality control, supplier follow-up and project management
• Excellent project management skills
• Ability to manage multiple stakeholders and prioritize tasks in a fast-paced environment
• Fluency in English; French is a plus
• Biotech knowledge is a plus
• Good communication skills for interacting with manufacturing partners

• Nice-to-have:

• Familiarity with bioproduction or pharmaceutical systems

• Familiarity with ISO standards
• Knowledge of optoelectronic packaging or microfabrication
