Job Description:

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. We are seeking an R&D Mechanical Engineer to develop the mechanical part of InSpek’s sensing systems. You will work on the design, prototyping, and manufacturing of optical 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.

Job Responsibility:

  • Design and iterate mechanical components and assemblies that meet cleanliness, sterility, and durability standards for bioproduction environments
  • Build and iterate prototypes using 3D printing, CNC machining, and other rapid prototyping methods
  • Conduct tests to validate performance and durability in real-world bioproduction conditions
  • Collaborate with internal teams and external partners to debug and refine mechanical designs
  • Optimize designs for cost, scalability, ease of assembly, and compliance with biotech requirements
  • Identify, qualify, and onboard subcontractors and engineering houses for specialized mechanical tasks
  • Work with CMOs, contractors, and industrialization partners to ensure mechanical components meet technical and quality standards
  • Contribute to procurement, timeline management, and technical documentation
  • Ensure smooth transitions from prototyping to volume production
  • Perform mechanical testing and validation to ensure components meet performance and regulatory requirements
  • Support quality control processes, with an emphasis on compatibility with bioproduction and pharmaceutical standards

Requirements:

  • 4+ years of experience (or equivalent) in mechanical engineering or industrial design, industrialization
  • Strong background in mechanics, system design, and integration, including proficiency with CAD tools and mechanical prototyping (e.g. 3D printing)
  • Hands-on experience with mechanical component selection, testing, and validation
  • Familiarity with hazardous environments such as bioproduction (preferred), space, and sub-sea
  • Experience with cleanroom, sterilization, material compatibility and radiation
  • Experience with supplier follow-up and project management
  • Excellent communication and project management skills
  • Ability to manage multiple stakeholders and prioritize tasks in a fast-paced environment
  • Fluency in English

Nice to have:

  • French is a plus
  • Knowledge of optoelectronic packaging or microfabrication
  • Familiarity with ISO standards
What we offer:
  • Health and life insurance (100%)
  • Meal vouchers
  • Gymlib account (access to gyms & sports)
  • Employee stock options (BSPCE)
  • Flexible remote work policy
  • Growth opportunities with potential for leadership roles
  • Regular social events
  • Inclusive culture
  • Unique opportunity to be an early employee at an innovative startup
