Thin Films Process Engineer

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 Thin Films Process Engineer
, you will lead the feasibility, process development, and equipment bring-up for cutting‑edge micro‑assembly processes used in flexible medical device manufacturing. This role will focus on developing and optimizing key processes, such as laser scribing, lift‑off and delamination of polyimide (PI) devices, tab bonding, ACF bonding, pick‑and‑place assembly, and wafer testing and inspection as well as other potentially.

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.

Main responsibilities:

• Development to Production Transfer:
  The principal responsibility of development team is to 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.
• Collaborate with equipment vendors to manage equipment bring‑up, qualification, and tool acceptance for thin film processes.
• Coordinate or conduct materials characterization using tools such as SEM, AFM, XPS, FTIR, and profilometers etc to ensure film quality and performance.
• Troubleshoot and resolve process issues related to thin film deposition, adhesion, and uniformity.
• Implement process control methodologies, including SPC (Statistical Process Control), to monitor and improve process stability and yield.
• Support the integration of new materials into device structures, ensuring compatibility with existing processes and substrates.
• Assist with process documentation, including work instructions, process flows, and risk assessments.
• Drive continuous improvement initiatives for thin film processes to improve yield and cycle time, throughput, and material reliability.

Mandatory Qualifications and

Soft skills:

• Bachelor’s and Master’s degree in Materials Science, Chemical Engineering, Physics, or a related field.
• Around 3 years experience in thin film deposition processes in a semiconductor, microfabrication, or materials development environment.
• Fluency in English required (company main language)
• Knowledge of PVD, CVD, ALD, and sputtering techniques.
• Experience with materials characterization tools (e.g., SEM, AFM, XPS, profilometers).
• Hands‑on experience with process optimization and equipment qualification in clean room environments
  .
• Familiarity with process control systems (SPC, FMEA).
• Strong understanding of substrate preparation, film adhesion, and material compatibility for multi‑layer structures.
• Analytical Problem‑Solver and Detail‑Oriented.
• Ability to work effectively across cross‑functional teams, including technicians, engineers, and external vendors.
• Comfortable in a fast‑paced, evolving environment with shifting priorities and new challenges.
• Ability to clearly document processes, write reports, and present technical findings to both technical and non‑technical audiences.

Nice to have:

• Experience working with novel semiconductor materials or biocompatible materials for medical or industrial applications.
• Knowledge of device integration and post‑processing techniques (e.g., etching, bonding).
• Experience with automated optical inspection (AOI) and yield management systems.
• Familiarity with MES (Manufacturing Execution Systems) and data warehouse systems.
• Previous experience in ISO 13485 or GMP‑compliant environments.
• Experience with vacuum systems, gas handling, and environmental controls for thin film processes.
