Job summary

Caelora, a Munich-based company pioneering high-energy ultrashort-pulse laser systems, seeks a senior scientist/engineer to design and develop ultra-high intensity laser systems. You will own dedicated projects and collaborate with multidisciplinary teams, including partners worldwide, to advance cutting-edge technology.

You will drive budgeting for energy, fluence, and temporal contrast, lead commissioning, and ensure robust, reproducible hardware development for next-generation systems in an

Qualifications

• PhD or MSc in Physics, Photonics, Optical Engineering, or related field.
• For MSc, extensive professional experience required.
• Expertise in setting up and operating high-power laser systems and diagnostic equipment.
• Experience with simulation tools for ultra-short, high-intensity laser systems and validating models against measurements.
• Professional experience in industrial integration of laser systems or industrial manufacturing environments.
• Experience applying industrial standards.
• Fluent in English.
• High flexibility, adaptability, and a proactive, can-do attitude.
• Strong quantitative and analytical skills.
• You are willing to reside in the greater Munich area.
• Willingness to travel.

Responsibilities

• Collaborate with multidisciplinary teams in the development, assembly, and operation of key components for the next generation of highly efficient, high-average-power, ultra-intense lasers.
• Perform calculations and simulations for OPCPAs and high-energy diode-pumped solid-state laser systems, and contribute to the overall laser system design, owning the energy, dispersion, nonlinear phase and fluence budgets
• Collaborate with the engineering team in designing and constructing laser (sub-)systems.
• Interact with external partners to steer and monitor their performance, e.g., by working with our R&D Team and leading optics manufacturers to advance the current state of the art in optical technology, and own the interfaces from what suppliers deliver through to technical acceptance
• Derive and own the technical specifications for the procurement of hardware, ranging from small, machined parts to large optical components from both local and international suppliers, with measurable requirements and verification methods, and assist the procurement team throughout the sourcing process.
• Stay up to date with the latest advancements and research trends in laser technologies by attending conferences and publishing findings in scientific journals
• Own the temporal contrast and prepulse budget across the chain
• Own the fluence budget and damage margin: specify coatings and qualify optics against measured LIDT before they are installed
• Lead commissioning and acceptance testing, in our laboratory and on customer sites, including the handover
• Design for a system that will be built more than once: reproducible alignment, documented procedures, and performance a customer can recover without us
• Contribute to an inclusive and collaborative team environment in which all team members feel supported, valued, and heard.
