R&D Engineer (f/m/d)

Your mission

Develop our next generation of photonic devices – from the first experiment to production

Location: Dortmund, Germany

Employment type: Full-time (40 hours/week)

Salary: EUR 65.000,00-80.000,00 gross per year

If you enjoy combining device physics, hands-on lab work and automation, and want to see your ideas turn into real products, we look forward to getting to know you.

• Development of new semiconductor devices, processes and products – from concept through prototype to small-volume production

• Improvement of existing devices and processes with regard to performance, yield, reliability and manufacturability

• Design, execution and documentation of complex experiments for device, process and reliability evaluation

• Development and improvement of measurement setups for electrical, optical, thermal and reliability testing, including non-standard measurement methods

• Development and maintenance of test automation software in LabVIEW, combined with Python, MATLAB or C/C++ where required

• Analysis of experimental and production data, including root-cause analysis and proposals for next steps

• Technical leadership of NRE projects, including scope, milestones, deliverables, progress tracking and risk management

• Direct communication with customers and translation of their requirements into development and test plans

• Preparation of processing specifications for internal and external semiconductor fabs and support of technology transfer to our contract manufacturing partners

• Training, support and, when required, supervision of R&D operators

• Preparation of technical reports and documentation as well as contributions to application notes and website content

• Presentation of results at scientific conferences and trade shows and co-authorship of publications

Your profile

• Master's degree or PhD in Physics, Electrical Engineering, Photonics, Materials Science or a related field

• Solid understanding of semiconductor device physics and operating principles

• Hands-on experience with semiconductor processing, testing and characterisation

• Experience in designing measurement setups and automating tests, ideally with LabVIEW

• Confident use of statistical and physical models to analyse experimental and production data

• Independent, structured working style and the drive to take technical ownership of projects

• Ability to explain technical findings clearly to colleagues and customers

• Fluent English language skills, both written and spoken

• Good German language skills

Nice to Have

• Experience with semiconductor lasers, optical amplifiers or other photonic devices

• Experience with device, optical, thermal or process simulation tools

• Knowledge of industrial standards and calibration procedures

• Experience in NRE or other customer-driven development projects

• Experience working in an optical lab and handling precision optics

• Scientific publications or conference contributions

Why us?

For our site in Dortmund, we are looking for an R&D Engineer (f/m/d) to strengthen our Research & Development team. You will take new devices and processes from the first experiment all the way to production, combining hands-on lab work with technical responsibility for customer projects.

Innolume was one of the first companies to bring quantum-dot semiconductor devices to market. Today, we develop optoelectronic devices based on InGaAs/GaAs quantum-well and quantum-dot technologies for wavelengths from 780 to 1350 nm, many of them tailored to individual customer requirements. Our two in-house MBE reactors allow us to grow our own epitaxial structures for both development and volume production. As we move towards high-volume manufacturing, this role offers the opportunity to shape our next generation of products from the very first idea.

What We Offer

• Technical ownership of your own NRE projects and direct contact with our customers

• A varied role spanning research, development, production and customer projects

• Participation in scientific conferences and trade shows

• An international, multicultural team with flat hierarchies

• Short decision-making paths and close collaboration across departments

• Individual training and continuous learning opportunities

• Flexible working hours and 30 days of annual leave

• From the 7th month of employment, additional benefits
