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
