Microfabrication Process Engineer (Advanced packaging)

Permanent employee, Full-time · Barcelona
Your mission

We are scientists, doctors, techies and humanity lovers, with the mission of pioneering real time precision neurology to cure brain-related disorders. INBRAIN harnesses the extraordinary material properties of Graphene, the world’s thinnest and nobel-prize winning material, to build high resolution neural systems. Our mission is to decode and modulate neural networks to restore people's lives.

As a Microfabrication Process Engineer (Advanced packaging), you will play a critical role in several key areas such as developing and optimizing Through-Glass Via (TGV) processes, wafer bonding, laser forming of glass, pick-and-place assembly, and Atomic Layer Deposition (ALD) for encapsulation. 

This position will involve process development, equipment bring-up, and automation integration to scale these technologies for production.

You will be at the forefront of bringing advanced healthcare solutions to market, making a tangible difference in people´s lives worldwide.

This position will be office-based in Bellaterra. 
Your profile

Main responsibilities:

  • Development to Production Transfer: manage the development-to-production transfer process, ensuring that prototype designs are effectively scaled for manufacturing with a focus on yield improvement, design optimization, and manufacturing readiness. This includes creating and refining the Bill of Materials (BOM), Bill of Processes (BOP), manufacturing equipment specifications, testing protocols, and manufacturing recipes.
  • Develop and optimize Through-Glass Via (TGV) processes, including drilling, filling, and metallization.
  • Lead wafer bonding process development, ensuring high yield and strong bond strength for multi-layer glass and semiconductor structures.
  • Drive the laser forming of glass for precision shaping, cutting, and structuring of wafers.
  • Support pick-and-place process development for precise assembly of components, including die placement and microelectronic packaging.
  • Collaborate with equipment vendors to support equipment bring-up, qualification, and production readiness.
  • Implement process control methodologies (SPC, FMEA) to monitor and improve process stability, yield, and repeatability.
  • Troubleshoot process issues and implement corrective actions to improve yields and reduce waste.
  • Document process flows, work instructions, and risk assessments to ensure processes are well understood and reproducible.
  • Work closely with automation engineers to integrate process automation for improved efficiency and consistency.
  • Support new product introductions (NPI) by ensuring processes are production-ready and scalable.


Mandatory Qualifications and Soft skills:

  • Bachelor’s or Master’s degree in Materials Science, Mechanical Engineering, Chemical Engineering, or Physics.
  • 3+ years of experience in microfabrication process development, particularly in glass-based technologies
  • Hands-on experience with Through-Glass Via (TGV) processes, wafer bonding, and laser processing of glass.
  • Fluency in English required (company main language)
  • Knowledge of pick-and-place assembly techniques for microelectronics packaging.
  • Familiarity with process control methodologies (SPC, FMEA, DOE).
  • Proven track record of equipment bring-up and process qualification in a clean room environment.
  • Willing to work directly with equipment and processes in a clean room environment.
  • Ability to troubleshoot and resolve complex process issues using a data-driven approach.
  • High precision in process development and documentation to ensure repeatable, high-quality results.
  • Strong communication skills to work effectively across teams, including technicians, engineers, and external vendors.
  • Comfortable managing evolving priorities and new challenges in a fast-paced production environment.
  • Proactively identifies areas for improvement and implements solutions to enhance process performance.


Nice to have:

  • Experience with vacuum systems and environmental controls for process tools.
  • Experience with thin film deposition processes such as ALD or PVD.
  • Knowledge of automated optical inspection (AOI) systems for yield monitoring.
  • Experience with bond strength testing and reliability testing for wafer-bonded structures.
  • Familiarity with automation integration and MES systems in manufacturing environments.
  • Previous experience in ISO 13485 or GMP-compliant environments.
  • Knowledge of robotics and motion control systems for pick-and-place equipment.
