The posting

Optical Design Engineers for our High Power Beam Combining team

Location: Farum, Denmark | Level: PhD / Postdoc / Experienced Engineer

The Mission: Build the Next Generation of SBC Systems

At Ibsen Photonics, we are developing Spectral Beam Combining (SBC) modules for high-power laser architectures. We are looking for creative, hands-on Optical Design Engineers to take full ownership of designing, building, and optimising our SBC platform.

This role bridges the gap between theoretical physics and industrial reality. You won’t just design on a screen; you will spend significant time in the lab, iterating rapidly from proof-of-concept to robust, production-ready, scalable systems.

Key responsibilities:

  • Design & Assemble: Develop compact, efficient SBC modules using Ibsen’s world-class transmission gratings, while considering optical beam paths, thermal effects and mechanical constraints.
  • System Optimisation: Drive performance by refining optical alignment, mechanical stability, and complex thermal management for high-power loads in a reiterative process: design – experiment – optimise.
  • Characterisation: Use advanced diagnostics to maintain beam quality (low M²) during power scaling, including wavefront sensing and spectral analysis.
  • Full Lifecycle Ownership: Source optical/mechanical components and manage the transition from experimental prototypes to scalable, volume-ready designs.
  • Global Collaboration: Work closely with an internal team and international partners, including potential overseas visits for joint prototyping and testing.

What you bring

You are a proactive problem-solver who thrives in a “build-test-learn” environment. Ideally, you possess:

  • Education: A PhD or Postdoc in Optics, Photonics, Laser Physics, or a related field.
  • Expertise: Hands on experience with (high-power) fibre and free-space optical systems, precise alignment, and experimental troubleshooting. Understanding of (and ideally experience with) SBC and CBC beam combining techniques. Beam quality measurement and analysis. Mechanical design of low-tolerance devices
  • Technical Knowledge: Deep understanding of Gaussian optics, beam propagation, and high-power laser effects (thermal lensing, runaway-effects, mitigation strategies).
  • Software Skills: Proficiency in optical simulation tools (e.g., Zemax) and familiarity with mechanical CAD.
  • Mindset: Independent enough to drive a project and work on your own, but collaborative enough to thrive in a flat-hierarchy, cross-functional team, sharing insights and discussing projects/next steps. The role is highly experimental and hands-on, requiring independence and a strong drive to make systems work in practice, not just on paper.
  • Security Clearance: You are a European citizen with no family ties to Russia or Russian allied territories, and you have a clean criminal record.

Why join Ibsen Photonics?

  • High Impact: Your designs will directly shape the future of high-brightness laser systems for manufacturing, defence, telecommunications, and science.
  • Freedom to Innovate: We value experimental drive—if you have a better way to align or stabilise a system, we want to see it.
  • Danish Engineering Culture: Enjoy a supportive environment with fast decision-making, real ownership, and a healthy work-life balance.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
