The posting

Develop advanced power electronics for high-performance laser systems

Do you want to work hands-on with power electronics in a highly specialized R&D environment, developing solutions used in advanced laser and photonics technologies?

Hamamatsu Photonics A/S is expanding its R&D organization and is looking for a Senior Power Electronics Engineer to strengthen its electronics capabilities.

About the Company

Hamamatsu Photonics is a global leader in photonics, laser and fibre technologies, employing more than 5,800 people worldwide.

Following the acquisition of NKT Photonics in 2024, the former NKT Photonics organisation now operates as the Lasers & Fibers Business Unit within the Hamamatsu Photonics Group, supporting applications within Quantum Technologies, Life Sciences, Semiconductors, Aerospace & Defence and Advanced Industrial Technologies.

Responsibilities

As Senior Power Electronics Engineer, you will take ownership of electronics development across the full product lifecycle—from early concept and design to validation, production, and optimization.

You will work in a multidisciplinary R&D environment, contributing to both detailed design and system-level solutions. This is a deeply technical, hands-on role with high ownership.

The role is based in Birkerød, Denmark and reports to the Team Lead Electronics.

Key responsibilities:

  • Design and develop power electronics for laser systems across the full product lifecycle
  • Own technical work packages and ensure delivery within scope, timeline, and quality targets
  • Develop system-level electronics architectures and design concepts
  • Collaborate closely with experts in optics, mechanics, and system design
  • Create reference designs to support scalability and standardization
  • Support manufacturing, custom solutions, and product improvements
  • Ensure compliance with relevant industry standards and certification requirements

What you will be doing (in practice)

  • Working on low-volume, high-margin, high-complexity systems
  • Translating unclear or evolving customer requirements into robust technical solutions
  • Contributing to both detailed circuit design and overall system performance
  • Taking ownership of solutions from idea → design → validation → production

Profile

You are a strong power electronics specialist with experience developing complex systems and a structured, solution-oriented mindset.

Experience

  • Senior-level experience in power electronics development (100W–10kW range)
  • Strong track record in PCB design and product development
  • Experience working across the full product lifecycle
  • Comfortable working in complex and evolving R&D environments
  • Experience collaborating with cross-functional teams and stakeholders

Technical expertise

You have strong experience in several of the following:

Power electronics design

  • DC/DC converter design and verification (kW range)
  • Analog circuit design (control loops, amplifiers, inrush circuits)

Hardware & components

  • Magnetic component design (inductors, transformers, chokes)
  • PCB design and productization

Simulation & analysis

  • Circuit simulation (e.g. LTspice, Pspice)
  • Worst-case analysis, component stress, MTBF, DFMEA

General

  • Strong understanding of switch-mode power electronics technologies
  • Experience working with external partners or suppliers

Benefits

Hamamatsu Photonics offers a highly innovative and collaborative working environment where you can influence both technology and product development while being part of a globally recognized photonics organization.

You can expect:

  • Market-competitive salary, including relocation support on a case-by-case basis
  • 12% employer-paid pension scheme
  • Annual bonus
  • A highly dynamic and growing business environment with strong long-term potential
  • High degree of autonomy and technical ownership
  • Exposure to senior leadership and international projects
  • A multicultural, knowledge-driven environment with highly skilled colleagues
  • Strong opportunities for professional growth and career development as the organization continues to scale
