Principal Magnet Cryogenics Engineer
for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections that have real specific content.
We need to parse the posting.
Job title: Principal Magnet Cryogenics Engineer (already shown, we don't repeat as heading).
We need sections:
- About the role: likely the "Position Overview" paragraph(s). Also maybe "About Thea Energy"? The instruction: Use for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So "About the role" corresponds to position overview. Also there is "About Thea Energy" which is company description; maybe that could be part of About the role? But we can include as part of About the role? The instruction says use those headings; we can include About the role heading and put the position overview text there. The company description could be included as part of About the role or maybe we could add a separate section? Not in list; better to incorporate into About the role.
- Responsibilities: from "Key Responsibilities" bullet list.
- Requirements: from "Required Experience" bullet list.
- Qualifications: maybe from "Technical Knowledge"? Could be considered qualifications. The list includes Technical Knowledge items. Could be Qualifications.
- Skills: from "Skills & Competencies".
- Benefits: from "Company Benefits" bullet list.
- Pay: from "$190,000 - $215,000 a year". That's pay.
- Schedule: not mentioned; maybe not include.
We must not include sections with placeholder or vague content. Pay is specific: salary range. So include Pay.
Schedule: not present, so omit.
We must not repeat job title as heading. Also not include Job ID etc.
We must remove boilerplate: cookie notice, privacy notice, apply for this job, Diversity And Inclusion, AI tools, etc. Also remove duplicated lines.
We need to preserve ALL substantive information; do not invent or summarize away detail. So we need to keep all details from those sections.
We need to format using headings, - for any list of duties/requirements/benefits, and
for prose.
Thus:
About the role
... (position overview plus maybe company description)
But we need to ensure we don't lose any substantive info. Let's extract:
About Thea Energy paragraph: "Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future."
Position Overview: "We are seeking a Principal Magnet Cryogenics Engineer with over 10-15 years of industry experience to lead the complete program lifecycle—from concept through commissioning—of large-scale cabled High-Temperature Superconducting (HTS) magnet systems for next-generation fusion reactors. In this role, you will hold end-to-end technical ownership for the cryogenic design, thermal-hydraulic modelling, forced-flow cooling distribution, and cryogenic integration of large-scale CICC (Cable-in-Conduit Conductor) or advanced stacked-tape HTS magnets. You will bridge megawatt scale cryogenic plant engineering with microscopic thermal-hydraulic magnet behaviour, leading multi-disciplinary teams through multi-million-dollar hardware deliverables."
We can combine both into About the role paragraph(s). Could be two elements.
Responsibilities: list items under "Key Responsibilities". Each bullet starts with a bold heading? Actually they are like:
Program Lifecycle Ownership: Lead the complete lifecycle (Conceptual, Preliminary, Detailed Design, Qualification, Fabrication, Assembly, Commissioning, and Decommissioning) for large-scale HTS fusion magnet cryogenic systems.
Cryo-Thermal System Architecture: Design, model, and validate gaseous helium (gHe), or sub-cooled liquid nitrogen (sLN2) thermal management systems tailored to high-field HTS cabled conductors (stacked HTS conductors).
Thermal-Hydraulic Modeling: Perform dynamic thermal-hydraulic analysis, transient load modelling (nuclear heating, AC losses, eddy currents, ramp rates), and margin calculations under operational and fault conditions.
Quench & Fault Management: Own the cryogenic response strategy during quench events, including rapid helium expansion, overpressure relief sizing, burst disc integration, and thermo-mechanical stress containment.
Large-Scale Infrastructure & Plant Integration: Define requirements for mega-watt class cryogenic plants, cold compressors, heat exchangers, sub-coolers, helium distribution boxes (valve boxes), and low-heat-leak transfer lines.
Joints & Current Leads: Oversee cryogenic thermal management for high-current demountable or permanent HTS joints and conduction-cooled hybrid (HTS/LTS) gas-cooled current leads (60+ kA).
Vendor & Subcontractor Governance: Manage major sub-contracts for large-scale cryogenic infrastructure, conductor fabrication, pressure vessels, and vacuum insulated systems (cryostats).
V&V and Commissioning: Plan and execute full-scale cryogenic and high-current magnet test campaigns, leading cool-down, steady-state operation, quench mitigation, and warm-up procedures.
We need to preserve all detail. So each bullet as
- with the full sentence.
Requirements: from "Required Experience". Bullets:
10-15+ Years of Direct Experience in cryogenic engineering and thermal-hydraulic design for superconducting magnet systems, with a primary focus on HTS tape/cable architectures (REBCO/BSCCO).
Large-Scale Fusion/Physics Program Delivery: Proven track record of ownership over large-scale (> $10M+) magnet work packages within fusion energy programs (e.g., W7x, ITER, JT60SA, KSTAR, DEMO) or major scientific facilities (e.g., CERN, FERMILAB).
Cabled HTS Architecture: Demonstrated expertise in high-current (tens of kA) cabled HTS configurations (e.g., Cable-in-Conduit Conductors, stacked tape conductors) and forced-flow cooling strategies.
Full Lifecycle Track Record: Experience taking at least one major superconducting magnet or cryogenic system from initial concept through initial cool-down and operational validation.
Regulatory & Code Compliance: Deep familiarity with pressure vessel standards applied to cryogenic temperatures (ASME BPVC Section VIII, EN 13445, B31.3) and cryogenic safety standards (ISO 21010/CGA).
We need to keep each as
- .
Qualifications: from "Technical Knowledge". Bullets:
HTS Material Physics: Solid understanding of critical surfaces for REBCO coated conductors, strain sensitivity, thermal margin assessment, and current sharing regimes.
Cryogenic Fluids & Thermophysical Properties: Mastery of low-temperature fluid dynamics (gHe, sLN2) using database tools.
Transient Thermal Analysis: Deep domain knowledge of AC losses (coupling, hysteresis, flux creep) nuclear volumetric heating, heat-leak budgets, and conduction/radiation thermal shielding (MLI design).
Instrumentation & Controls: Extensive knowledge of low-temperature thermometry (Cernox, TVO, optical fibers/FBG), cryogenic flow meters, pressure transducers, and cryogenic valve telemetry.
We could treat these as Qualifications.
Skills: from "Skills & Competencies". Bullets:
Computational Tools: Proficiency in finite element analysis (FEA) and thermal-hydraulic system modeling tools (e.g., COMSOL Multiphysics, ANSYS Thermal/CFD, MATLAB/Simulink).
System Engineering & Requirements Flowdown: Capability to write clear system requirement documents (SRDs), interface control documents (ICDs), and lead major design reviews (CoDR, PDR, CDR).
Leadership & Team Mentorship: Demonstrated ability to lead cross-functional engineering teams (structural, electrical, vacuum, systems) and mentor junior magnet/cryogenic engineers.
Strategic Risk Mitigation: Mastery of FMEA, applied to cryogenic system failures, vacuum loss (loss of vacuum/L VAC), and runaway quench scenarios.
Benefits: from "Company Benefits". Bullets:
Comprehensive health benefits (e.g. medical/dental/vision)
Employee equity stock options

Pay: "$190,000 - $215,000 a year". This is a specific statement; we can put in a

Schedule: not present, omit.
We must not include any boilerplate like "It’s not necessary to meet all of the skillsets outlined above..." etc. Also remove "Diversity And Inclusion" etc.
