We are expanding our backend and packaging activities targeting large quantum processor units (QPUs). As a Backend Process Development Engineer, you will contribute to planning and build-out of a cleanroom expansion dedicated to these processes. Your job duties will include process flow design, tool configuration, and vendor interactions. You will also have opportunities for hands-on operator work supporting process ramp-up and validation.

Your work will directly impact the performance and scalability of IQM’s superconducting quantum computers, focusing on production readiness, high reliability, and quality control.

What will I be doing?

• Develop, optimize, and characterize die packaging and backend processes for cryogenic and extreme-temperature environments

• Define and design backend processes from concept to production readiness

• Drive process transfer to production, including documentation, training, and qualification

• Specify, procure, and qualify new process tools

• Support site-acceptance testing (SAT), tool installation, tool health monitoring and maintenance and ramp-up activities in collaboration with the equipment team

• Contribute to cleanroom build-out together with external consultants and infrastructure teams

• Perform hands-on process implementation, testing, and validation

• Collaborate cross-functionally with wafer fab, QPU designers, test teams, operations, and facilities

• Interface with external tool vendors to evaluate capabilities and specifications
  

What skills do I need?

• Proven experience with solder reflow and microbump / flip-chip interconnect processes

• Strong understanding of UBMs (Under-bump metallizations), and solder alloy systems

• Experience in die package design for cryogenic or extreme environments

• Demonstrated track record in setting up or scaling die packaging production lines

• Solid knowledge of cleanroom operations, contamination control, and process qualification

• Minimum 3 years of cleanroom operator experience

• BSc, MSc or PhD in Electrical Engineering, Applied Physics, or a closely related field

Preferred skills that can be useful but are not mandatory:

• High pad-count dies and fine-pitch interconnects

• Mechanical and thermal design of die packages or interposers

• Electroplating and surface finishing processes

• Wave, laser, or selective soldering

• Failure analysis techniques (X-ray tomography, SEM, optical microscopy)

• Mask layout design for semiconducting or superconducting foundry processes

• Ceramic substrates, hermetic or vacuum packaging

• Microwave / RF fundamentals and impedance-controlled designs

• Vacuum technologies, cryostats, or low-temperature systems

• Advanced PCB design (high-frequency, rigid-flex, low-loss materials)

• Automated testing, probing, or pick-and-place systems

• Experience with superconducting materials or quantum device fabrication

What can I expect from IQM?

• At IQM, you can expect to work on groundbreaking quantum hardware projects. Your work will directly contribute to the development and industrialization of next-generation quantum processor units, including large-scale systems, from defining backend process concepts to bringing new tools and cleanroom capabilities online and transferring them into production.

• You will thrive in a creative, open, and hands-on start-up environment where engineers are trusted with real responsibility. You will be encouraged to experiment, iterate, and continuously improve while working with cutting-edge tools and technologies.

• IQM offers a highly international and collaborative workplace, bringing together experts from diverse cultural and technical backgrounds.

• As a rapidly growing organization, IQM provides the opportunity to play a meaningful role in scaling both technology and operations.
