Process Development Engineer

We are seeking a Process Development Engineer to join our particle dispersion technology team. You will be responsible for the design and development of a major unit operation from concept through commercial scales. Come help us bring this groundbreaking technology to the world.

• Design and scale up solids feed, heat transfer, fluids control, and monomer distribution systems
• Develop practical process operating windows through experimentation and computational modeling, where appropriate
• Establish system robustness, design a maintenance program, and prepare for field operations
• Collaborate with the aircraft engineering team to design systems against aerodynamic, thermal, electrical, and mass requirements
• Support field trials and experimentation
• Conduct failure analysis and root-cause investigations during development cycles
• Document design rationale, test protocols, and process specifications for manufacturing handoff

• BS in chemical engineering, mechanical engineering, or a related discipline
• 5+ years of hands-on industrial process design, build, scale-up, or manufacturing engineering experience
• Hands-on experience with any of the following: high-temperature process chemistry, reactor design, high-temperature thermal transfer fluids, continuous solids feeding systems, corrosion mitigation, or high-velocity gas mixing
• Demonstrated ability to work independently on cross-functional engineering problems and drive developmental progress through uncertainty elimination
• Strong technical communication skills with the ability to interface with teams in aircraft integration, atmospheric science, cloud microphysics, atmospheric sensing, government affairs, and related areas
• Comfort with experimental strategy, analytical design, instrumentation, and translating data into decisions

• Demonstrated lead experience with at least one complete design-build-decide cycle
• Familiarity with aircraft or aerospace operations, such as flight ops, certification, power budgets, or vibration environments
• Understanding of micron- and nanometer-scale particle chemistry, characterization, and dynamics
• Meaningful equity
• Full health, dental, and vision benefits
• In-person five days a week in San Francisco, CA
