Team Lead Photonic Packaging (m/f/d) in Münster (full-time)

Münster
Full or part-time
Permanent employee

Your mission

Are you an experienced packaging expert passionate about advancing the field of
photonics and quantum applications? We are seeking a Team Lead Photonic Packaging
Engineer to head our packaging efforts. In this hands-on leadership role, you will guide a
small, dedicated team of engineers and oversee the complete packaging assembly of our
single-photon detectors. You will be responsible for tackling the unique challenges of
packaging Photonic Integrated Circuits (PICs) for operation at cryogenic temperatures (2
Kelvin).

Key Responsibilities
• Team Leadership: Lead and mentor a hands-on packaging team (2+ engineers),
planning workflows and ensuring efficient project execution.

• Advanced Packaging Processes: Develop and execute high-precision fiber-to-chip
coupling strategies, focusing on maximizing coupling efficiency and stability at
cryogenic temperatures.

• Assembly & Integration: Perform and oversee critical assembly steps including
chip attachment and wire bonding, ensuring reliability under extreme thermal
cycling.

• Thermal & Mechanical Design: Design submounts and packaging interfaces. You
will specifically address thermal management challenges, calculating and mitigating
mechanical stress caused by CTE (Coefficient of Thermal Expansion) mismatches
between chip, submount, and adhesive layers at 2K.

• Process Optimization: Transition manual packaging steps into automated processes.

• Interface with Design: Collaborate closely with the PIC design team to optimize
Mode Size Converters and spot sizes for improved coupling tolerances.

• Strategic Sourcing: Select and qualify materials (epoxies, solders, submounts)
suitable for cryogenic environments.

Your profile

To excel in this role, we are seeking candidates with the following qualifications and skills:
  • Education: Master’s degree or PhD in Engineering, Physics, Photonics, or a related
    field

  • Industry Experience: You possess several years of professional experience in the photonic packaging industry, ideally gained at specialized packaging service providers, photonic foundries, or optical assembly houses.

  • Technical Expertise:
    • Deep understanding of PIC Packaging (Fiber array attachment, Flip-chip,
      Wire bonding).


    • Proven experience with cryogenic packaging or packaging for harsh
      environments is highly desired.


    • Solid knowledge of thermal management and material properties (CTE) at
      low temperatures.


    • Familiarity with PIC design principles (especially Mode Size Converters) to
      guide the design team on packaging constraints.


    • Leadership: Experience in technically leading small teams or projects.

    • Mindset: You are a "hands-on" leader who enjoys working in the lab while also
      handling strategic planning.

Why us?

What we offer:

• Impact: Opportunity to shape the next technological revolution with impact on all
industries by enabling quantum technologies.

• Compensation: Competitive salary and compensation package above industry
standards.

• Culture: A team-centric workplace with flat hierarchies, open communication, and
an open-door policy.

• Flexibility: Remote work options and a family-friendly environment.

• Growth: The chance to take on significant responsibility from day one and build
your own processes.
