Sr Experimental Plasma Scientist
About The Position
An Experimental Plasma Scientist is a technical contributor within Avalanche’s Science organization. The role advances understanding of plasma physics as it applies directly to Avalanche’s fusion systems in an environment of rapid iteration, incomplete information, and evolving requirements. This is not a purely academic role: the scientist works closely with experimental systems, diagnostics, simulations, and cross-functional engineering teams to inform design decisions, interpret results, and guide future experiments. The role calls for strong scientific judgment, new approaches, and helping the team move faster and smarter. Avalanche is a Seattle-based start-up developing compact fusion machines for clean, energy-dense power generation. Its modular design is intended to serve applications ranging from austere environments and deep-sea vehicles to maritime transport and lunar power. The company emphasizes hands-on collaboration, rapid development, learning, and iteration. The position is based in Tukwila, Washington, with occasional travel for equipment procurement, integration, or collaboration as needed.
Requirements
- PhD in plasma physics or a closely related field, or equivalent depth of experience.
- Demonstrated ability to approach complex plasma physics problems analytically.
- Comfort interpreting theory, simulation, and experimental results.
- Ability to work with a diverse team and independently, prioritize work, and make progress in ambiguous environments.
- Clear communication skills, including the ability to explain complex ideas across disciplines.
- Comfort iterating quickly and revising assumptions as new data emerges.
- Comfort coding in Python or similar languages.
Nice To Haves
- Direct experience working with fusion-relevant plasma diagnostics.
- Electrical and/or mechanical technician experience.
- Experience assembling experimental, prototype, or low-volume hardware.
- Experience with interlocks or other safety systems.
- Familiarity with vacuum or ultra-high-vacuum systems.
- Experience with cryogenic systems or fluid handling.
- Experience working around high-voltage systems.
- Experience with pneumatic systems and precision plumbing.
- Automation or controls installation experience.
- Surface-mount and through-hole soldering experience.
- Prior work in fast-paced, hardware-driven R&D environments.
Responsibilities
- Design, analyze, and interpret plasma experiments in collaboration with the broader science team and engineers.
- Translate experimental results into clear, actionable recommendations for future experiments.
- Integrate experimental data, simulations, and theory to inform conclusions and guide next steps.
- Help identify the most important questions at each stage of development and prioritize effort.
- Work with mechanical, electrical, instrumentation, and software engineering teams to incorporate plasma physics considerations into system design.
- Communicate complex plasma physics concepts clearly to non-plasma specialists across the organization.
- Provide scientifically grounded input for product and system trade studies.
- Mentor more junior scientists and engineers.
- Share knowledge, review analyses, and contribute to a collaborative and curious science culture.
- Help strengthen team practices around documentation, analysis, and communication.
Benefits
- Excellent medical, dental, and vision benefits; the company pays 100% of premiums.
- 10 paid holidays and a company-wide December holiday break.
- Generous paid vacation and sick time.
- Weekly employer-provided team meals, a well-stocked kitchen, and employee events on and off-site.
- Opportunity for equity.
- Small, tight-knit team with low barriers to action.
- Exposure to a wide variety of problems for hands-on professional growth.
