Who We are Looking for

We encourage candidates from diverse backgrounds to apply, even if you do not meet every qualification listed below.

We are seeking a highly technical, hands-on cryogenic systems expert with demonstrated experience building dilution refrigerators and related ultra-low-temperature hardware. The ideal candidate understands the underlying thermodynamics as well as the mechanical, thermal, and integration constraints required to produce robust, repeatable systems.

This role reports directly to the R&D Lead and works closely with the broader R&D team, Production, Service, and other key technical stakeholders to ensure new designs are performant, manufacturable, and field-ready.

Experience with cryogenic heat switches, sintered powder heat exchangers, high-density RF wiring, and cryogenic vibration isolation is strongly valued.

What Will You Do

Working under the technical direction of the R&D Lead and in close collaboration with  other cross-functional stakeholders, you will contribute across the full lifecycle of ZPC’s cryogenic systems — from design refinement through production integration and field support.

Your responsibilities will include:

• Collaborate with the R&D team to address complex thermal, mechanical, and integration challenges in dilution refrigerator systems.
• Design and refine dilution refrigerators, cryostats, and ancillary cryogenic subsystems.
• Improve cooling power, base temperature performance, and system stability through structured design iteration.
• Lead cross-functional R&D projects to deliver customized sub-Kelvin systems, ensuring seamless transitions from customers’ experimental needs to robust, field-ready hardware.
• Liaise directly with Production teams to resolve manufacturability constraints and improve repeatability of system builds.
• Support the Service team in diagnosing and resolving field performance issues, including root cause analysis at millikelvin regimes.
• Contribute to development and implementation of technical standards to improve reliability, documentation, and assembly consistency.
• Participate in technical design reviews to ensure alignment between design intent and production execution.

Preferred Experience / Technical Skills

We are most interested in candidates with strong low-temperature physics fundamentals and applied systems engineering experience.

• PhD or MSc in Physics, Engineering, or equivalent industry experience.
• Direct experience building dilution refrigerators (not solely operating them).
• Strong background in thermodynamics and heat transfer at cryogenic temperatures.
• Experience with cryogenic heat exchangers and gas-gap heat switches.
• Familiarity with superconducting magnet integration and cryogen-free platforms preferred.
• Strong technical documentation and reporting discipline.
• Passport and ability to pass security clearances for customer site installations if required.

Nice to Have / Considered an Asset

• Finite element modelling for thermal, fluid or structural analysis.
• Experience with high-density RF wiring in cryogenic environments.
• Vibrational analysis using sensitive transducers
• Experience transitioning prototype systems into structured production builds.
• Ability to work independently while contributing to a multidisciplinary engineering team.

What Will You Bring

• Deep technical curiosity and analytical rigor.
• Systems-level thinking with attention to thermal, mechanical, and integration detail.
• Excellent written and verbal communication skills for cross-functional collaboration.
• Commitment to precision, engineering discipline, and continuous improvement.
• Ability to operate effectively within a growing, technically demanding organization.
• Proven academic or industrial track record with strong references.

Compensation and Benefits

• Competitive salary commensurate with experience and education
• 100% employer-paid group benefits, including:
  • Health and dental
  • $750 annual Health Care Spending Account
  • Employee & Family Assistance Program (EFAP)
• Flexible Paid Time Off policy
• Paid statutory holidays
• Employee-paid life insurance and long-term disability benefits
