Role overview

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.

Key responsibilities

  • 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

Required qualifications

  • 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

Preferred qualifications

  • 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

Compensation & Benefits

  • Base salary: $130,000–$180,000
  • Meaningful equity
  • Full health, dental, and vision benefits
  • In-person five days a week in San Francisco, CA
