Senior optical design engineer F/H

Who are we ?

Founded in 2013, Cailabs designs, manufactures, and develops innovative photonic solutions for the space, industry, telecommunications, and defense sectors. A global specialist in laser shaping, the company has accelerated its growth in the space field with turnkey optical ground stations that integrate atmospheric turbulence compensation technology. This makes it one of the first companies to harness very high data rates enabled by optics in a commercial ground station.

Cailabs currently has over 120 employees, including 32 PhDs. With 26 patent families filed, the company is one of the most innovative companies in France. It is headquartered in Rennes, with offices in Paris and Washington (USA).

Job description

Apply your expertise in free-space optics to innovative beam shaping for various technical projects and industrial applications! Join the Simulation team at Cailabs where your skills will advance the future of optical technologies. 

At Cailabs, we are always on the lookout for talents who are keen on blending their optics expertise with numerical simulations. If you have a previous hands-on industry experience in designing optical systems, come join our Simulation Team to apply your skills to innovative projects, from laser shaping for space communications to spearheading advancements in industrial laser processing. 

Within this role, you will find a positive group dynamic and will lead the design of advanced optical systems as well as contributing to and using state-of-the-art numerical simulations of various physical systems: laser beams, atmospheric turbulence phenomena, photonic circuits, etc. 

Experience the pulse of a forward-thinking tech company, from the birth of a prototype to its journey towards full-scale industrialization. 

You will be a key part of the Simulation Team within our Technical Department, and you will have a direct line to the head of the team.

Responsibilities : 

• You are responsible for designing optical systems and centralizing optical developments at Cailabs.
• As dedicated specialist for the standard optical design software used in the industry, primarily Zemax, you are in charge of spreading best practices, providing  internal training on these tools, etc.
• You will also participate in optical design projects, tolerancing, and optimization of optical systems for a wide range of applications, including free-space optical communication (satellite-to-ground and point-to-point) and industrial laser processes.

• You will work in collaboration with interdisciplinary teams to integrate optical designs with electronic and mechanical systems for their industrialization, contributing to comprehensive system-level solutions. 

• You will design and implement advanced numerical tools in Python, add to the internal code libraries of the company, and use them to simulate a range of physical systems. 

Essential skills

• Advanced degree or Phd in physics or in optical engineering. 
• Experience in the design of optical systems, with an expertise in using optical design software such as Zemax or Code V. 
• Familiarity with numerical physics, for example the propagation of laser beams (open-source or proprietary libraries). 
• Comfortable with Python or Matlab, and a knack for coding. 
• Fluency in English and French to discuss technical projects with your team. 

Bonus Points for: 

• Experience with free-space optics: experimental optical setup, beam alignment, data acquisition. 
• Familiarity with collaborative coding practices and tools, with experience contributing to shared codebases in a team setting being advantageous. 
• Prior exposure to an industrial environment, especially in roles interfacing with product development and production units. 
• Basic proficiency in French is a plus. 

When you join Cailabs, you'll find :

• A dynamic team of engineers and PhDs who share your desire to put their skills to work on stimulating technical challenges,
• Collective emulation and a strong intellectual interest in your work,
• A company at the cutting edge of technology, from the development of prototypes through to the industrialisation phases.

Plus : 

• Time for sharing and conviviality (annual seminar, meals, group games, sports activities, etc.),
  100% health insurance cover,
• A bonus system to reward collective and individual performance.
• Finally, joining Cailabs is the assurance that everything will be done to help you perform, improve and take on new challenges.
