About the role
Ambature is seeking a highly skilled fabrication scientist to support the development and fabrication of next‑generation superconducting devices. This role centers on cleanroom microfabrication, thin‑film processing, and electrical testing, with the goal of maturing Ambature’s high‑temperature superconducting technologies into robust, repeatable, and scalable processes.
This is a hands‑on, cleanroom position based in Waterloo, Ontario working in the QNFCF, the University of Waterloo’s 8000 sq ft nanofabrication facility, and its satellite labs. 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 Own Ambature’s multi‑step fabrication process end‑to‑end and serve as the internal and external subject‑matter expert Develop, optimize, and execute cleanroom fabrication processes for superconducting devices (e.g., Josephson junctions, SQUIDs) Drive new process innovations by exploring novel materials, architectures, and fabrication approaches to push device performance and manufacturability forward Perform thin‑film deposition (PVD), photolithography, etching, and metrology in an ISO 5-7 cleanroom environment 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 technical and non-technical audiences Support IP development through process documentation, invention disclosures, and technical contributions Ensure safe operation of cleanroom tools and adherence to facility protocols
Required Qualifications PhD or M.Sc (with equivalent experience) in engineering physics, materials science, electrical engineering, nanotechnology, or a related field 3 - 5 years of post-graduate experience developing multi-step fabrication processes in a cleanroom environment Proficiency with thin‑film deposition, photolithography, and wet/dry etching Proficiency with metrology tools such as SEM, AFM, and profilometry 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 Canada. Start date negotiable
Desired Qualifications Experience with superconducting materials or devices (e.g., ReBCO, Josephson junctions, SQUIDs) Experience with EBL for nanofabrication of small-scale devices Familiarity with cryogenic measurement systems (e.g., PPMS, dilution refrigerators, LHe/LN2 probes) Patents, publications, or demonstrated contributions to fabrication‑driven R&D
What We Offer This is a full‑time position with a salary range of $125,000 - $150,000 CAD Comprehensive benefits Equity/stock options 4 weeks paid vacation Opportunities for IP contribution and publications

About Ambature
Based in Waterloo, Ontario and Scottsdale, Arizona, Ambature, Inc. is the world leader in a-axis high-temperature superconducting technology. We design superconducting materials and quantum devices to power an innovative, sustainable future. Nearly half of Ambature’s intellectual property portfolio is dedicated to computing and sensing, while the other half is dedicated to clean energy—the generation, transmission and storage of electricity. Our unique materials and scalable device architectures enable two important shifts in the advanced chips industry: mass production and higher operating temperatures of superconducting devices.
If the transistor is the most fundamental semiconductor device, then the Josephson junction (JJ) is the most fundamental superconductor device. JJs are building blocks for sensors, quantum computers, and high-performance or energy-efficient classical computers. Our JJs can be manufactured at scale in any major foundry in the world using standard silicon fabrication equipment.
Semiconductors conduct electricity with some resistance. Resistance generates heat in wires, batteries, antennas, smartphones, computers, etc. Heat is the major barrier to advancements in semiconductor power, speed, density, efficiency, and reliability. Our materials address the heat problem because superconductors conduct electricity without resistance. Superconductors typically operate at very cold temperatures, but Ambature’s roots are in research towards room temperature superconductivity.
There are low-temperature superconductors (LTS) and high-temperature superconductors (HTS). HTS devices reduce cooling power consumption and coolant costs by an order of magnitude. Ambature’s a-axis HTS JJs will be the first commercially available, mass produced HTS tunnel junctions. They are viable because we have overcome historical technological barriers by mastering a-axis rather than conventional c-axis epitaxial growth.
