Float
Senior Propulsion & Energy Systems Engineer
Location: Full-time On-Site (CA)
Float is an early-stage aerospace company developing advanced
airship systems
for large-scale cargo applications. We are focused on solving hard aerospace problems and translating ambitious concepts into real, tested hardware. Our team is small, execution-driven, and building a new airship platform from first principles.
The Role As Senior Propulsion & Energy Systems Engineer, you will own the design and development of critical energy and propulsion-adjacent systems for Float’s airship platform. This is a
hands‑on, system‑level role
focused on safety, reliability, manufacturability, and integration.
You will take responsibility for energy‑related subsystems from early architecture and trade studies through
physical prototyping, testing, and iteration , working closely with the Lead Aerospace Engineer and founding team.
Responsibilities
Design and develop
energy and propulsion‑related subsystems
for a large‑scale cargo airship
Define system architectures that balance
performance, safety, reliability, and manufacturability
Lead trade studies and requirements definition for energy storage, distribution, and integration
Drive
design‑for‑manufacturing (DFM)
decisions to support repeatable production
Build and evaluate
physical prototypes and proof‑of‑concept hardware
Develop and execute
system‑level test plans , validation procedures, and failure analyses
Collaborate closely with structures, aerodynamics, avionics, and manufacturing teams to ensure clean system integration
Qualifications
Degree in Aerospace, Mechanical, or related engineering field, or
equivalent real‑world experience
Strong background in
propulsion, energy systems, pressure systems, or complex mechanical systems
Proven experience taking systems from
concept through prototype and test
Solid understanding of
safety‑critical design principles
and system reliability
Experience with
CAD , system‑level modeling, and engineering trade studies
Comfortable working in fast‑moving, early‑stage environments with evolving requirements
Strong engineering judgment and bias toward hands‑on problem solving
Nice to Have
Experience with
hydrogen or alternative energy systems
Background in
aerospace, automotive, or industrial energy systems
Familiarity with
certification‑aware or regulated design environments
Hands‑on experience building and testing mechanical or energy‑related hardware
Prior experience at an aerospace startup or skunkworks‑style team
Why Join Us This is a rare opportunity to shape the core engineering DNA of a company redefining how cargo moves across the planet. You’ll take on meaningful responsibility early, build groundbreaking vehicles, and grow alongside a world‑class team pioneering the future of sustainable air mobility.
