Senior Fluids Engineer

Senior Fluids Engineer - Lead Development of Advanced Thermal & Flow Systems

Hawthorne, California | On-site

Opportunity Summary

We are building next-generation power generation systems designed to deliver reliable, scalable energy for emerging industrial and compute infrastructure. By combining advanced thermal systems, high-performance turbo machinery, and modern manufacturing approaches, our team is developing a new class of compact power hardware capable of being deployed faster and more efficiently than traditional solutions. We are seeking a Senior Fluids Engineer to own fluid system development across the product lifecycle.

This individual will play a critical role in defining flow architectures, pressure management strategies, thermal-fluid performance, and system integration. The ideal candidate is comfortable moving between analysis, hardware development, testing, and system-level problem solving while operating in a highly collaborative startup environment.

About Us

We are a venture-backed energy technology company building advanced power systems for the next generation of industrial and digital infrastructure. As an early-stage team, we move quickly, prioritize technical excellence, and believe the best engineers thrive when given meaningful ownership over challenging problems.

Job Duties

• Own fluid system architecture from concept through deployment
• Design high-pressure gas and fluid systems including piping networks, valves, manifolds, and flow control hardware
• Develop thermal-fluid models to predict system performance across operating conditions
• Perform CFD analysis and flow simulations to guide design decisions
• Define system operating envelopes, pressure losses, flow requirements, and transient behaviors
• Collaborate closely with turbo machinery, thermal, controls, and mechanical engineering teams
• Support prototype development, integration, testing, and troubleshooting
• Drive system-level performance optimization and root cause investigations
• Contribute to design reviews, technical trade studies, and architecture decisions

Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related discipline
• 5+ years of experience developing fluid systems for aerospace, propulsion, energy, turbo machinery, or industrial equipment
• Strong understanding of fluid mechanics, thermodynamics, and heat transfer
• Experience using CFD and thermal-fluid simulation tools
• Experience designing high-pressure fluid or gas systems
• Ability to take ownership of complex technical problems from concept through validation

Preferred Experience

• 7+ years of relevant industry experience
• Experience with supercritical fluid systems
• Experience supporting hardware testing and development programs
• Background in rocket propulsion, gas turbines, turbo machinery, or advanced energy systems
• Startup or rapid development environment experience

Why Join Us

• Early engineering ownership with direct influence on product architecture
• Opportunity to solve challenging multidisciplinary engineering problems
• Exposure across design, analysis, testing, and system integration
• Work alongside experienced engineers from aerospace, energy, and advanced hardware industries
