Senior Mechanical Design Specialist
$138.1k - $172.6kFusion Energy Base
Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy. We are rapidly designing and building a pulsed magnetic fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems. Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand. You can read more about us in this letter from our founders. Why This Role Matters Pacific Fusion is seeking multiple Senior Mechanical Design Specialists to support the development of advanced mechanical systems for next‑generation fusion energy technology. This role is ideal for creative, hands‑on mechanical designers with strong CAD expertise who can work independently while collaborating closely with scientists, engineers, and cross‑functional technical teams. Successful candidates will develop and analyze complex mechanical systems, conduct research to resolve challenging engineering problems, and translate concepts into fully detailed, production‑ready designs. Depending on experience and qualifications, candidates may also provide technical leadership, including planning and leading multiple complex projects. What You’ll Do Independently analyze complex design problems and develop robust mechanical design solutions that satisfy all requirements and constraints. Translate design solutions into detailed layouts and assemblies using advanced Computer‑Aided Design (CAD) tools. Develop supporting documentation for design solutions, including analysis, schedules, cost estimates, safety notes, and procedures. Capture design intent using Creo Parametric, including model‑based definition practices where applicable. Maintain accurate design documentation and configuration control within Windchill or equivalent PLM/ELM systems. Estimate schedules and costs to determine effective approaches for design, materials selection, and fabrication to meet project deliverables. Prepare and present technical material for design reviews, procedures, and related documentation. Provide technical mentorship to fellow designers and contribute to workforce planning, task prioritization, and work assignments. Participate in formal design reviews and engineering change processes. Author, review, and approve engineering reports, manuals, and other technical documentation. Present designs and technical analyses to engineering leadership and project stakeholders. What You Bring Bachelor’s degree in Mechanical Engineering, Mechanical Engineering Technology, or a related technical field, or an equivalent combination of education and relevant experience. Significant applied experience with Creo Parametric and Windchill (or equivalent CAD/PLM systems). Advanced knowledge of CAD/PLM systems and configuration management best practices. Strong working knowledge of drafting standards, including ASME Y14.5 Geometric Dimensioning and Tolerancing (GD&T). Demonstrated ability to analyze and interpret complex design requirements and develop original, practical engineering solutions. Experience with hardware design, fabrication, assembly techniques, material selection, testing processes, and manufacturing methods. Ability to read, interpret, and follow complex engineering drawings, specifications, sketches, and procedures. Proven ability to manage multiple tasks with attention to detail, accuracy, and independent follow‑through. Strong written and verbal communication skills, including the ability to present technical information clearly. Bonus Points For Demonstrated technical or project leadership experience. Experience developing staffing plans, mentoring engineers or designers, and contributing to performance development. Familiarity with project management methods and tools. Experience using CAD‑supported Finite Element Analysis (FEA) to support conceptual and detailed design decisions.
