Ambature is seeking a highly skilled Process Engineer to support the development and fabrication of next-generation superconducting devices. This role centers on cleanroom microfabrication, thin-film processing, and device-level testing, with the goal of maturing Ambature’s high-temperature superconducting technologies into robust, repeatable, and scalable processes.

This is a hands-on, fabrication-focused position based in San Jose, California, working onsite at a leading research partner’s cleanroom facility. You will collaborate closely with Ambature’s Science Team to scale our R&D-level process into robust manufacturable workflows while improving yield, increasing throughput, and accelerating prototype development.

In this role, you will:

• Develop, optimize, and execute cleanroom fabrication processes for superconducting devices (e.g., Josephson junctions, SQUIDs)

• Perform thin-film deposition (PVD, PLD, sputtering), photolithography, etching, and metrology in an ISO 5-7 (Class 100–1000) cleanroom environment

• Perform device-level electrical characterization to validate process performance

• Implement process controls, documentation, and continuous improvement methodologies to enhance reproducibility and yield of target KPIs

• Apply structured, data-driven engineering methods to diagnose issues and optimize processes

• Collaborate with Ambature’s Science Team to translate device designs into process flows and provide fabrication-driven insights

• Maintain detailed experimental records, analyze data, and communicate results clearly to internal and external stakeholders

• Support IP development through process documentation, invention disclosures, and technical contributions

• Ensure safe operation of cleanroom tools and adherence to facility protocols

Required Qualifications:

• M.Sc or B.Eng (with equivalent experience) in engineering physics, materials science, electrical engineering, nanotechnology, or a related field

• Hands-on experience with microfabrication processes in a cleanroom environment

• Proficiency with thin-film deposition, photolithography, and wet/dry etching

• Proficiency with metrology tools such as SEM, AFM, profilometry, and optical inspection

• Experience with device testing and electrical characterization (I-V, 4pt, contact resistance)

• Strong proficiency with data-driven engineering methods (DoE, RCA, and SPC)

• Strong data analysis skills and proficiency with scientific plotting/reporting tools

• Excellent communication skills and the ability to work both independently and collaboratively

• Strong attention to detail, time management, and process discipline

• Must be eligible to work in the United States and available to begin as soon as possible (target: May 2026)

Desired Qualifications:

• Experience with superconducting materials or devices (e.g., ReBCO, Josephson junctions, SQUIDs)

• 2+ years of industry experience in semiconductor, quantum-device, or advanced-materials fabrication

• Experience developing or optimizing multi-step process flows

• Familiarity with cryogenic measurement systems (e.g., PPMS, dilution refrigerators, LHe/LN2 setups)

• Patents, publications, or demonstrated contributions to fabrication-driven R&D

Compensation:

This is a full-time position with a salary range of $110,000 - $125,000 USD.
